ABSTRACT
Heat transfer is a process inherent in most power generation methods, including
light water nuclear reactors. Control Rod Drive Mechanisms control the position of
Control Rod Assemblies within a reactor core and are vital to nuclear plant operations.
Control Rod Drive Mechanisms each contain a Coil Stack Assembly, which requires
heat removal to ensure proper operation. This project investigates alternative cooling
methods for a Coil Stack Assembly. Lower Coil Stack Assembly temperatures by
means of conduction cooling are needed for operating nuclear plants applying for
operating license extensions. Enhanced Coil Stack Assembly designs which utilize pin
fins, straight fins and internal cooling cavities are required to reduce or eliminate cooling
fan power requirements in future power plant designs. Steady state heat transfer finite
element analyses are performed using ANSYS Workbench™ Version 11.0, utilizing 3-D
models and heat transfer material properties of current Coil Stack Assemblies. ANSYS
results from modified Coil Stack Assembly designs are then compared to baseline
geometry ANSYS results.
Baseline cooling analyses are performed to validate the FEA models.
The
baseline results show that the average temperature at the inner surface of the coils during
normal operating conditions is approximately 3.63 °F above the maximum technical
limit of 392 °F.
The baseline results are considered acceptable based upon the
conservative boundary conditions used in the FEA model. An analysis in which exterior
surfaces of the Coil Stack Assembly are held at a constant 100 °F temperature is
performed. These boundary conditions, which simulate a conduction cooling apparatus
that is form fitted to the Coil Stack Assembly, are shown to reduce the temperatures at
the inner surfaces of the coils by an average of 183°F. Coil Stack Assemblies which
utilize pin fin and straight fin arrays are also analyzed.
An average temperature
reduction of 66.5 °F at the inner surfaces of the coils is achieved using pin fin arrays
with a total additional surface area of 2553 in2 per Coil Stack Assembly. Straight fin
arrays with 5728 in2 of additional surface area per Coil Stack Assembly reduce
temperatures by an average of 95.5 °F at the inner coil surfaces.
Forced internal
convective cooling is shown to reduce average coil temperatures by 44.6 °F when
ix
internal cooling cavities of ovular shape and approximately 1561 in2 cooling area are
used.

Introduction
The nuclear power industry is in the midst of a resurgence commonly referred to
as the “nuclear renaissance”. Approximately four hundred nuclear power plants were
built world-wide during the mid- to late-twentieth century. A drop in energy demand,
construction cost overruns as well as the accidents at Three Mile Island and Chernobyl
were ultimately responsible for the cancellation of hundreds more plants in planning or
construction phases. A variety of factors, including efforts to curb climate-changing
greenhouse gas emissions, are now encouraging many nations world-wide to reconsider
the use of nuclear power generation.
In a light water nuclear steam supply system (NSSS), an example of which is
shown in Figure 1, water coolant flows through channels in the fuel bundles within the
reactor vessel (RV), where the heat energy is transferred from the fuel bundles to the
coolant.
Figure 1: Typical 4-Loop Nuclear Steam Supply System

One of the ways in which the reactivity within the fuel core is maintained is
through the use of control rod assemblies (CRA), which introduce negative reactivity
when lowered into the core. The heights of the CRAs within the core are maintained by
control rod drive mechanisms (CRDM) located on top of the RV. A CRDM is an
electromechanical drive that vertically positions the CRA within the RV. The CRDM
aids in start up and shutdown of the reactor, adjusts or maintains the power level of the
core during normal operation and can quickly introduce negative reactivity into the core
in the event of an unusual event or intentional reactor trip. Figure 2 shows a schematic
of the CRDM system and its sub-assemblies.

The four major sub-assemblies that comprise a CRDM system are: the coil stack
assembly (CSA), the pressure boundary, the latch assembly and the drive rod assembly.
The CRDM operates by utilizing electro-magnetic flux fields generated by the CSA to
drive magnetic latch assembly components in a pre-determined fashion within the
pressure boundary. The timing and sequence of these fields determines whether the
CRA is inserted into or withdrawn from the reactor core.

Proper CSA operation is vital to the operation of a nuclear reactor. If the coils
within the CSA overheat and become damaged, they will short out electrically, resulting
in a dropped CRA. While this design is inherently safe, it means that any failure of the
CSA will prevent the startup criticality of the fuel core. Therefore, heat removal from
the CSA is important during all phases of plant operation. The CRDM CSA is currently
cooled using forced air convection.
A cooling shroud containing large fans and
ductwork encases the periphery of the CRDM systems as part of an integrated system
and provides cooling air flow rates of at least 100 ft/s over the coil stack assemblies.
This cooling air maintains the coil temperatures within the CSAs at or below 392 ºF;
keeping the coils cooled helps to improve latch assembly stepping characteristics and
increases the operating life of the CSA.
Many nuclear power plants which were originally designed for a forty year life
are applying to have their operating licenses extended by twenty years and may apply for
an additional twenty year life extension. Given that the effective plant design lives are
now longer than originally intended, enhanced CSA cooling methods are desired to help
ensure reliable coil function through their extended lives. A reduction in required fan
motor size for adequate CSA cooling has two potential benefits: a reduction in operating
and maintenance costs if smaller fan motors are used, or increased cooling margin if
larger fan motors continue to be used.
Additionally, these modifications may be
beneficial in advanced reactor designs which seek to utilize the current coil material
technology at higher temperatures.
The need for enhanced CSA cooling includes in-situ retrofit solutions for
operating plants as well as design concepts for future components. The CSAs that are
currently in use within operating plants are unable to be modified significantly for many
logistical and licensing issues.
This project focuses in part on alternative cooling
solutions, conductive cooling apparatuses which can readily be added to existing CSAs.
These solutions include an apparatus which is approximately form-fitted to the exterior
CSA surfaces and a simpler apparatus which fits rigidly along the flat CSA side surfaces.
Enhanced cooling methods are also needed for future CSA design concepts. The
CSA coil housings are made from cast iron and have the potential to be investment
casted with internal cavities. Forced internal convective cooling with water as the
3
cooling medium is considered and the effects of varying cavity shapes and sizes on CSA
cooling are determined. Features can also be cast or machined into the external surfaces
of the CSA housings. Enhanced external convective cooling by utilization of pin fin and
straight fin arrays is investigated; specifically, the effects of different pin fin and straight
fin geometries and array layouts on CSA cooling is determined.
It is important to note that many assumptions are made in this project regarding
the analysis models and inputs; these assumptions are made conservatively whenever
possible. The primary purpose of this project is to show that alternative Coil Stack
Assembly cooling methods are feasible by comparing analyses to a baseline model.

Background
Thermal management of the CRDM system through heat rejection from the
individual CRDM components to the surrounding area is vital to normal reactor startup,
operation and shutdown. Prior work has been performed which investigates cooling of
control rod drives for a high temperature engineering test reactor. Initial thermal cooling
flow analyses [1] evaluated the flow of air around the standpipes within which the
control rod drives were situated, similar to the cylindrical CRDM pressure housings.
The 3D analyses, in which the control rod drive standpipes were modeled as pillars,
were performed using thermal-hydraulic analysis and thermal analysis software codes.
The flow analyses results were evaluated and cooling air ducts were added within the
stand pipe room to aid in cooling the control rod drives. Operational cooling tests were
then performed to determine the control rod drive temperatures [2]. The experimental
results showed that the control rod drive temperatures were maintained at temperatures
below 180 °C using indirect forced air cooing via cooling air ducts.
This project involves heat transfer analysis of components which undergo
internal heat generation, conduction heat transfer and convective heating and cooling
loads. Established conduction and convection heat transfer principles are used to solve
for the boundary conditions acting on the various CRDM components. The boundary
conditions are then inputted into a finite element analysis (FEA) model to determine the
resulting component temperatures.
Conduction is the transfer of energy through particles in direct contact with each
other. It is governed by Fourier’s Law, which is taken from [3] and shown in its onedimensional form in Equation 1. Fourier’s Law states that the rate of heat transfer is
proportional to the temperature gradient in a material. Different forms of Fourier’s Law
can be used to calculate the total heat flow into or out of an object, or the local area heat
fluxes.

Examples of conduction cooling are often seen in electronic devices, where latent heat is
removed from components through the use of heat sinks.
Convection is the transfer of heat energy via bulk fluid motion, as opposed to
stationary particles in conduction heat transfer. Convection is characterized in two
different ways: natural convection and forced convection. Natural or free convection
occurs due to buoyancy effects created by heat-induced density changes. Where free
convection occurs by natural forces, forced convection is induced by an external source
such as pumps, fans, etc. Forced convection is found in many cooling applications such
as condensers, electronics and aerospace component applications.
Convection heat
transfer is often expressed in the form of Equation 2, which is known as Newton’s law of
cooling [3].

Where:
(2)
q " = heat flux, Btu/s-m2;
h = heat transfer coefficient, Btu/in2-hr-°F;
Ts = surface temperature, °F;
T = free stream temperature, °F;
Cooling convection is enhanced by the addition of cooling surface area via
extended surfaces in the form of straight fins and pin fins.
Extended surface designs
vary in shape and size; however the most common forms are pin fins and straight fins of
uniform cross section. From [3], it is shown that for fins of uniform cross section, the
fin heat transfer is given by Equation 3.

Tb = base surface temperature, °F;
T = free stream temperature, °F;
It is seen from Equation 3 that the heat transferred from a fin of uniform cross
section is dependent upon material properties, geometry and boundary conditions. The
efficiency of straight fins and pin fins, taken from [3], is shown in Equation 4. This
equation is used to characterize the thermal performance of each of the pins.

h = heat transfer coefficient, Btu/in2-hr-°F;
P = perimeter, in;
k = thermal conductivity, Btu/in-s-°F;
Ac = cross sectional area, in2;
It is shown in Equation 4 that straight fin and pin fin efficiency is a hyperbolic function
of fin geometry and material properties. The effects of variations in fin geometry,
specifically the length and perimeter, on CSA heat transfer and resulting steady state
temperatures are investigated in this project.

Pin fins typically utilize circular or rectangular cross sections and protrude at a
right angle to the surface of the cooled body. An example is a heat sink for electronic
component cooling is shown in Figure 3.
Figure 3: Pin Fin Heat Sink
Straight fins also extend at right angles to the cooled body, however they typically travel
over the entire length of the body with no disconnects. An example of straight fin
application is seen in automotive radiators, as shown in Figure 4.
Figure 4: Straight Fins on Automotive Radiator
8
Internal cooling convection is a process whereby fluid is forced through cavities
within a component in order to provide enhanced cooling to a particular portion of the
component. The cooling fluid depends on the application. For example, plane engines
utilize air passing through the engines at high velocities for internal cooling. Cooling is
achieved by creating small cavities through which a portion of the air can pass as it
travels over the turbine vanes. Use of liquid heat transfer mediums for internal cooling
can provide much higher levels of heat transfer due to higher heat transfer coefficients in
liquids than in gases.
Finite element analysis software can be utilized to calculate the temperature
distribution in an object based upon boundary condition inputs. The software first
breaks the model into differential element volumes. Boundary conditions are then
applied and a mathematical model is created using governing equations for the
differential element volumes. The FEA program solves the mathematical model and
then calculates the temperatures at each of the differential element nodes, in order to
determine the temperature distribution throughout the component. In this study, the heat
transfer analyses are performed using ANSYS Workbench Version 11.0 software. The
steps that were performed for each of the analyses are shown below.
1. Create 3-D solid model in AutoDesk Inventor™ Version 2009.
2. Import native Inventor assembly into Workbench meshing environment.
3. Generate mesh using maximum refinement Workbench settings.

Analysis
This section describes the analysis used to evaluate cooling methods for Control
Rod Drive Mechanism Coil Stack Assemblies (CSAs). The internal CSA coil heat
generation, CRDM system boundary conditions and convective heat transfer coefficients
are calculated for use in the different FEA model configurations. FEA model parameters
such as coolant properties, air flow characteristics, CSA surface temperatures, and pin
fin and straight fin characteristics are defined.
In all of the analysis cases, the
assumptions used to create the FEA models are listed within their respective section.
FEA meshing settings are also discussed, along with the methods used within the FEA
model to reduce computing resource demands.
Figure 2 shows the CRDM sub-
assemblies and direction of cooling air flow passing over them.

Boundary Conditions
3.1.1
Coil Heat Generation
Historical operating plant data shows that the heat rejection over the entire length
of the CRDM is approximately 41,000 Btu/hr. However, the local heat generation
within the CSA coils during normal operation directly impacts the cooling of the CSA;
therefore specific values are calculated for each of the coils. The positions of the three
copper wire wound coils within the CSA are shown in Figure 2. The heat generation
values within the coils are calculated using the measured current passed through the coils
and the resistance of the copper wire. The stationary (bottom) and movable (middle)
coils are identical in size and number of copper wire windings. The lift (upper) coil has
the same inner and outer diameters but is larger in height and therefore contains more
copper wire windings. Resistance within the coil is a function of temperature; resistance
increases with temperature. The electrical resistance of the copper wire at 392 °F, the
maximum allowable coil temperature, is conservatively used to calculate the heat
generation values.
The electrical resistance of copper increases linearly with
temperature; Equation 5 is used to calculate the corresponding electrical resistance of the
coil wire at the elevated temperatures. Note that Equation 5 requires the use of Celsius
10
temperatures be used.
The Celsius temperatures used are equivalent to ambient
temperature and maximum allowable coil temperature.

Due to the heavy load that the CRDM lifts during withdrawal and insertion steps,
the CSA coils are supplied more current during stepping operations than when holding
the drive rod stationary. Although the CRDMs spend the majority of their operating life
in hold-mode with reduced current supplied only to the stationary (lower) coil, the time
averaged stepping currents of all three coils will conservatively be used to calculate the
heat generation values of each coil. This ensures that the CSA cooling is adequate for
situations when the CRDMs are stepped continuously.
The control systems which
power the CSA coils are current-limited and therefore the amount of current supplied to
each coil is known. A portion of the power supplied to the CSA coils is used to perform
work, i.e. CRA insertion or withdrawal. However, it is conservatively assumed that all
power supplied to the CSA coils is converted into heat. The heat generation, taken from
[4], is shown in Equation 6.

Heat Transfer Coefficients
The heat transfer coefficients for the internal and external CRDM areas are
calculated as input to the heat transfer analyses.
The heat transfer coefficient is
calculated for the inner diameter (ID) of the Pressure Housing, which is exposed to
reactor coolant (subcooled water) at 550 °F and 2250 psia. The heat transfer coefficients
are also calculated for the external Pressure Housing area below the CSA, the CSA, and
the Pressure Housing area immediately above the CSA; all of which are exposed to
cooling air. Figure 5 shows the convective heat transfer regions and their respective
lengths.

Interior Pressure Housing Surface
The heat transfer coefficient is calculated for the ID surface of the Pressure
Housing from an elevation 17” below the CSA to 7” above the CSA, as shown in region
13
1 of Figure 5. Region 1 is meant to represent the reactor coolant in contact with the
Pressure Housing over characteristic lengths which impact CSA cooling. The Guide
Sleeve, which rests below the Latch Assembly, acts as a barrier to prevent thermal
siphoning between the coolant in the RV and the coolant in the CRDM Pressure
Housing. Equation 7 is used to determine the heat transfer coefficient.

Where: h1 = heat transfer coefficient, Btu/in2-hr-°F;
Nu = Nusselt Number, dimensionless;
k = thermal conductivity, Btu/in-s-°F;
L1 = characteristic length, in.
Since the values of k and L1 are known from Table 3, the Nusselt number is
now calculated.
The coolant flow within the Pressure Housing is considered
insignificant because the Guide Sleeve, which resides below the Latch Assembly (Figure
2), acts as a thermal flow barrier. The Nusselt number for natural flow over a plate is
calculated using Equation 8, from [6]. Note that this equation is limited to conditions for
which Gr x Pr > 1010.

Equations 10, 9 and 8 are solved in series and the resulting Nusselt Number is then used

surface. The values are shown in Table 5.

Housing below the CSA in Region 2 are shown below. Equation 11, taken from [7], is
used to calculate the heat transfer coefficient for forced flow over a column. Based on
empirical plant operating data, the average air velocity over the CSAs will be assumed as
100 ft/s. The properties of cooling air are taken from Table 4.

The heat transfer coefficient is calculated for the forced air flow over the CSA as

Internal CSA Housing Cooling Cavities
Based upon the irregular geometry of the CSA housings and a cored hole that
runs adjacent to the ID of the CSA housings, it is not feasible for a helical internal
cooling cavity to be utilized. Therefore, an ovular shaped internal cooling cavity which
spans the height of each of the flat CSA housing sides will be investigated. For the
purposes of this project, it will be assumed that component cooling water at 100 °F, 100
psia and 50 ft/s is supplied to each of the CSA cavities at a sufficient flow rate, such that
the heat transfer coefficient is constant along the entirety of the cooling cavities. For
simplicity, the cooling water flow is considered fully developed and all of the cooling
cavities will be subjected to the same heat transfer coefficient and cooling temperature.
The properties of the component cooling water are shown in Table 9.

Because the coolant flow is through an ovular shaped cavity, the hydraulic

Meshing
The CSA models are analyzed using ANSYS Workbench Version 11.0 as
outlined in Section 2.0. The models are meshed using the ANSYS default settings for
path conforming tetrahedrons with a relevance of 0 on a scale of -100 to 100. The
resulting mesh is shown in Figure 6. The mesh contains 69818 nodes and 32990
elements.
Figure 6: Default ANSYS Tetrahedron Mesh
Setting the mesh relevance to a maximum of 100 refines the mesh to 185237
nodes and 95422 elements, an almost three-fold increase in number of mesh nodes. The
refined mesh is shown in Figure 7.
21
Figure 7: ANSYS Tetrahedron Mesh at Maximum Refinement
While the default mesh parameters are acceptable, the maximum mesh
refinement parameters are used when possible in order to produce more accurate results.
In the convection cooling analyses involving pin fins, complex model geometries and
computing resources available require the models to be reduced to a quarter section of
the original geometry. This is acceptable due to the axisymmetric nature of the CRDM
sub-assemblies. The model is conservatively sectioned so that the quarter geometry
contains the least cooling surface area of the four quarters possible. Figure 8 shows the
plan view of the meshed quarter section model. In all ANSYS cases, the model is first
meshed, boundary conditions are applied and then the analysis is performed.

FEA Model Inputs
The FEA model boundary conditions, shown in Table 11, are calculated in
Sections 3.1.1 and 3.1.2 based upon empirical plant operating data. The intent is to
mimic those boundary conditions experienced by the CSA during normal plant
operation. It is important to note that heat transfer coefficients are calculated for the
regions shown in Figure 5: (1) the internal surfaces of the Pressure Housing, (2) the
external surfaces of the Pressure Housing below the CSA, (3) the external surfaces of the
CSA and (4) the external surfaces of the Pressure Housing above the CSA. The CSA
heat transfer coefficient is calculated by treating the CSA as a flat plate; therefore all
four CSA surfaces have the same heat transfer coefficient. Additionally, testing and
23
operating plant data have shown an approximate 50 °F temperature increase in the
cooling air temperature as it passes over the height of the CSA. This 50 °F temperature
increase is assumed to occur in a linear fashion such that it is incorporated into the FEA
models in 10 °F increments as shown in Table 11.

Baseline Cooling Analyses
The baseline cooling analysis of the CSA is performed by simply applying the
loads in Table 11 to the various components of the FEA model, as shown in Figure 9.
The heat loads in Table 11 are what the Pressure Housing and CSA experience during
normal stepping operations.
24

3.5
Conductive Cooling Analyses
The conductive cooling analyses are performed by first applying the heat loads in
Table 11 on the Pressure Housing and CSA components. However, instead of applying
the cooling convection loads to the Pressure Housing and CSA exteriors, specific CSA
surfaces are held at a fixed temperature of 100 °F. Holding the surfaces at a fixed
temperature simulates a conductive apparatus removing heat from the CSA. Normal
component cooling water is typically available on site at 70 °F nominal, however a water
temperature value of 100 °F is assumed for these analyses, to account for potential heat
loads imposed on the cooling water as it travels through the reactor containment building
to each of the CSAs. The flow rate of the component cooling water is assumed to be
sufficient to maintain the conductive cooling apparatus at a constant temperature despite
25
potentially high heat fluxes.
The thermal conductivities of individual CRDM
components that make up the CRDM system are defined as input to the heat transfer
analyses. For conservatism, all thermal conductivities shown in Table 12 are taken at
the maximum allowable coil temperature of 392 °F.

Conductive cooling Case 1 assumes that only the flat sides of the CSA housings
are held at constant temperature, which correlates to a straight-sided apparatus that could
be utilized on existing CSAs. Figure 10 shows the typical areas (highlighted in dark
green) of the CSA housings which are selected within the FEA model for this analysis.

Conductive cooling Case 2 assumes that both the flat sides and the angled
surfaces of the CSA housings are conductively cooled. This correlates to an apparatus
which is profiled to both the flat sides and the inward-angled surfaces of the CSA. This
profiled apparatus could be utilized on existing CSAs. Figure 11 shows the typical areas
(highlighted in dark green) of the CSA housing which are selected within the FEA
model for this analysis.

3.6
Convective Cooling Analyses – Pins
The convective cooling analyses of pin fin cooling effects are performed by
applying the heat loads and convective cooling loads from Table 11 on the quarter
section ANSYS model Pressure Housing and CSA components including the added pin
fins. Since the amount of convective cooling is dependent on surface area, it is expected
that the cooling convective heat transfer will increase as the area increases due to the
27
addition of pin fins.
An increase in cooling convection will result in lower CSA
component temperatures. The pin fin sizes and spacing are shown in Figure 12. The
cooling air flow over the external Pressure Housing and CSA surfaces is shown in
Section 3.1.2 to be turbulent. It is assumed that the air flow acts on all external surfaces
of the CSA.

The convective cooling analyses of straight fin cooling effects are performed
similar to the analyses of pin fins. Since the bases of the analyses are similar, it is
expected that as the total surface area added by the straight fins increases so will the
cooling convective heat transfer, resulting in lower CSA temperatures. The calculated
heat loads and convective cooling loads are shown in Table 11. The straight fin sizes
and spacing are shown in Figure 14. The cooling air flow over the external Pressure

Convective Cooling Analyses – Internal
3.8
The internal convective cooling analyses are performed by applying the heat
loads and convective cooling loads from Table 11 on the Pressure Housing and CSA
components. However, the external convective cooling loads are replaced by inputs
from Table 10. Since the amount of convective cooling is partially dependent on surface
area, it is expected that as the total surface area added by the fins increases so will the
cooling convective heat transfer.
Though the fluid temperature is assumed to be
constant from inlet to outlet for each CSA housing, the temperature is increased for each
housing, similar to the increase in temperature for the pin and fin convective cooling
analyses. The internal cooling cavities are defined in Table 15.

Results
Finite element analyses have been performed for several CSA model configurations
based upon boundary conditions calculated in Section 3.1. The analyses performed
include baseline, conductive cooling, pin fin cooling, straight fin cooling and internal
cooling. Baseline analyses were performed to verify the FEA model and calculated
boundary conditions.
The conductive cooling analyses were performed to prove
feasibility for use in existing plants. Finally, fin and internal convective analyses were
performed to investigate enhanced cooling methods for future CSA designs. The results
of the analyses and the maximum coil temperatures are presented for each configuration
analyzed.
4.1
Baseline Analysis
The baseline analysis using existing CSA geometry and operating boundary
conditions (including stepping operations) shows that the three coil assemblies are able
to operate near the maximum coil temperature limit of 392 °F. The maximum coil
temperatures are calculated for the ID surfaces of the coils, since the ID surfaces are
under the largest thermal loads from the Pressure Housing.
The maximum coil
temperatures for the baseline analysis are shown in Table 16.

The temperature distribution throughout the CSA under normal operating
conditions, as presented in Figure 17, shows that the temperatures within the coils are
slightly above allowable limits on the ID surfaces.
The higher than allowable
temperatures are likely due to the conservatisms built in to the boundary conditions.
Based upon the temperatures being over allowable limits by approximately 3.63 °F, the
baseline FEA analysis and related boundary conditions are considered acceptable for use
in other analyses.

Conduction Analysis
Two conductive cooling analyses are performed: one which takes only the flat
sides of the CSA into consideration (“straight”) and one which includes both the flat and
curved surfaces of the CSA (“profiled”). The first analysis, which represents a cooling
apparatus that fits rigidly along the length of the CSA, holds the flat sides of the CSA at
a constant temperature of 100 °F. The second analysis, which represents a cooling
apparatus that is closely form-fitted to the angled surfaces of CSA, holds both the flat
and the inward contoured surfaces of the CSA at a constant temperature of 100 °F. The
results of these analyses are shown in Table 17.

Table 17 shows a significant decrease in all three coil temperatures, for both
cases in which external surfaces are held at constant temperature.
The average
temperature reduction is 148.6 °F for Configuration 1 (straight) and is 182.8 °F for
Configuration 2 (profiled). It was expected that the profiled conductive cooling analysis
would produce lower temperatures since a larger surface area was held constant; these
additional surface areas are also in closer proximity to the three coil locations. The
temperature distribution from the profiled configuration is shown in Figure 18.
Figure 18: Conduction Cooling Temperature Distribution
Figure 18 shows the external surfaces held at a fixed temperature of 100 °F.
These external surface temperatures, meant to represent the effects of a conductive
34
cooling apparatus, result in coil temperatures approximately 175 °F at the periphery of
the coils and about 213 °F at the ID surfaces.
Convection Analysis – Pins

Four convection cooling analyses were performed to evaluate the effects of
different pin designs protruding normal to the flat vertical sides of the CSA housings.
Results of these analyses are shown in Table 18 along with the pin efficiency of each
configuration.

The average temperature reduction ranged from 50 °F for Configuration 1 to 66.5 °F for
Configuration 3.
Note that the pin fin efficiencies decreased with pin diameter
reduction, however total heat transfer increased due to the increased quantity of pins
within each array. This increase in convective surface area corresponds to the lower coil
temperatures shown for Configuration 3. It was expected that the configurations with
more pin surface area would produce lower temperatures. Configurations with more
pins could not be analyzed due to computing limitations. The temperature distribution
from the most effective cooling results, Configuration 3, is shown in Figure 19.

Figure 19 shows that the coils are maintained at approximately 300 °F through

The temperature distribution from Configuration 4, which is the most effective,
is shown in Figure 20. The efficiency of each pin decreased with reduction of fin cross
sectional area, however the quantity of fins within each array also increased, resulting in
increased external surface area. This increase in convective surface area corresponds
with the larger temperature reductions for Configuration 4.

Conclusions
CRDMs control the positions of CRAs within a reactor core and are vital to the
operation of light water nuclear reactors. In order to ensure reliable operation the of the
CRDM system, a significant amount of heat must be removed from the CRDM CSA.
This project evaluated several different heat removal methods for the CRDM CSAs
through utilization of ANSYS finite element analysis software. First, a baseline analysis
was performed to verify the FEA model and calculated boundary conditions. Next,
conductive cooling apparatuses were analyzed by holding specified surfaces at a
constant temperature within the FEA model.
Conductive cooling analyses were
performed for two cases: a simple apparatus which fit along the flat surfaces of the CSA
and a second case in which the apparatus conformed to the external surface profiles of
the CSA. Enhanced convective cooling analyses were then performed to determine the
effect of various pin fin arrays and straight fin arrays on CSA coil temperatures. Lastly,
an analysis was performed to determine the effect of internal cooling cavities on CSA
coil temperatures.
The results of the baseline analysis showed that the FEA model inputs, specifically
the model geometry, material properties and CRDM system heat loads, were valid. The
resulting maximum coil temperatures were 3 °F above the technical limit; this was
attributed to conservatisms built into the boundary condition. The baseline FEA model
was therefore considered acceptable for use. Verification of the baseline FEA model
allows for its use in future CRDM system heat transfer analyses as well as larger,
integrated system analyses.
The conductive cooling analyses resulted in the largest CSA coil temperature
reductions. These coil temperature reductions were based on the assumption that the
conductive cooling apparatuses were able to maintain the exterior surfaces of the CSA at
a constant temperature, despite the potential for large heat fluxes at these surfaces. The
profiled conductive cooling configuration, which contained more surface area cooling,
provided lower coil temperatures. This was expected due to the increased surface area
cooling and the proximity of the additional cooling surfaces to the CSA coils. The
results of the analyses show that under the assumed boundary conditions, there is
39
potential to significantly reduce the temperature of the CSA coils in existing nuclear
power plants, which can help to extend their operational limits.
This temperature
reduction also has the benefit of allowing for the elimination of cooling fans and
ductwork that are located above the CRDMs on the RV. Additionally, the resulting
large coil temperature reductions suggest a possibility for use of conductive cooling
apparatuses in future high-temperature CRDM designs.
The analyses of pin fin and straight fin arrays on the CSA produce temperature
reductions in all of the CSA coils. The coil temperature reductions are shown to be a
function of added cooling surface area; more surface area equates to more heat removal
from the CSA. The FEA analyses yielded larger CSA coil temperature reductions for
the straight fins than for the pin fins. However, the pin fin geometry analysis was
limited by computing resources, constraining the maximum total pin fin area to only
45% of the total straight fin area. In either case, CSA coil temperature reductions
suggest that pin fins or straight fins, which are easily added to the cast iron CSA
housing, have the potential to significantly decrease the cooling fan power requirements
at future nuclear power plants.
The current CSA housing geometry does not allow for significant modification,
therefore only one internal housing cavity configuration was able to be analyzed. The
analysis shows temperature reductions in all of the CSA coils. Therefore, there is a
potential for internal cooling to be used in future CSA designs, in order to eliminate
cooling fans and associated ductwork that are located above the CRDMs on the RV.
Additionally, internal CSA cooling has the potential for use within future high
temperature reactor designs.
