This report describes the results of a project to improve the generic component failure database for the
Savannah River Site (SRS). Additionally, guidelines were developed further for more,advanced applications
of darabase values. A representative list of components and failure modes for SRS risk models was genetaed
by reviewing existing safety analyses and component failure data bases and from suggestions from SRS
safety analysts. Then sources of data or failure rate estimates were identified and reviewed for applicability.
A major source of information was the Nuclear Computerized Library for Assessing Reactor Reliability, or
NUCLARR.’ This source includes an extensive collection of failure data and failure rate estimates for
commercial nuclear power plants. A recent Idaho National Engineering Laboratory report on failure data
from the Idaho Chemical Processing Plant was also reviewed? From these and other recent sources, failure
data and failure rate estimates were collected for the components and failure modes of interest. For each
component failure mode, this itiorrnation was aggregated to obtain a recommended generic failure rate
distribution (mean and error factor based on a Iognormal distribution). Results are,presented in Table 1 in
this report.
A major difference between W generic database and previous efforts is that this effort estimates
failure rates based on actual data (failure evews) rather than on existing failure rate estimates. This effort was
successful in that over 75°/0 of the results are now based on actual data. Also included is a section on
guidelines for more advanced applications of failure rate data.

1. INTRODUCTION
As part of an overall effort to upgrade the methodologies for stiety analyses of nonreactor
nuclear facilities at the Savannah River Site (SRS), a new generic component ftilure database was
developed. The project to update the SRS generic component ftilute database had several goals:
Provide information for various failure modes for each component, where possible. An
example is to provide ftilure rates for valve ftilure to open/close upon demand and valve
spurious operation, rather than just valve ftilure. Such ftilure mode information is often
necessary for detailed fault tree models.
Base component ftilure rates on actual data (ftilure events) wherever possible.
Use the most up-to-date and applicable data sources available.
Provide a clear documentation trail for each component failure rates estimate, such that
others can review the basis for each estimate.
The entire project was structured such that these goals could be accomplished. All of the goals were
met.
Based on a review of existing stiety analyses and component failure databases, and based on
additional input from SRS safely analysts, a comprehensive list of components and ftilure modes
was generated. The list is shown in Table 1. Approximately 500 component and ftilure mode
combinations were identified. Given this list of components and failure modes, sources were
identified that contained applicable failure data or failure rate estimates. A section on guidelines for
the use and applications of fhilure rate data is also included.
2. DATA SOURCES
Sources used to develop the SRS component generic database may contain actual failure
data or failure rate estimates. Also, sources containing failure data may vary in the quality or detail
of the information. Therefore, three categories of sources were established:
Category 1- Sources with actual failure data obtained from a detailed review of failure
events (to ensure applicability to the failure mode being considered) and a detailed review of
component populations and exposure duration’s (or demands). Such data include the
plant-specific component ftilure data collected for probabilistic risk assessments (PRAs) or
reliability studies. The NUCLARR1 database has 19 Category 1 sources, all from nuclear
power plants. For this project the Savannah River Site (SRS) reactor data were added. The
data sources include the following:

Including these Category 1 sources increased the Category 1 data by nearly 20%.
Category 2- Sources with actual failure da@ but which have an added uncertainty in the data
compared with Category 1 sources. This added uncertainty can result from a less comprehensive
search for actual failures, a more approximate method for determiningg component populations or
exposure duration’s (or demands), or a less clear breakdown of failures into the failure modes of
concern. NUCLARR has 10 Category 2 sources “inits database. For this project, an additional five
Category 2 sources were identified and used
NPRD-3S -By carefhlly reviewing failure mode information presented in tables in this
document, the failure data presented in NPRD-3 could be divided into the failure modes of
interest for this project.
0REDA7 - Failure data iiom components in offshore oil drilling facilities are presented in
this report. In some cases judgment was needed to break down the data by ftilure mode.
WIN-330 - This document lists ftilure data obtained from the Department of Energy (DOE)
Idaho Chemical Processing Plant. However, this document does not distinguish failure
modes, so some judgement was needed to break down the data by failure mode.
Tritium8 9 ‘d 10-These documents include ftilure data from a tritium handling facility at the
Los A&& National Laboratory. Again, judgement was needed to break down the data by
failure mode.
LNG111- Failure data from liquid natural gas facili~ components are presented in this
document. Judgement was needed to break down the data by failure mode.
Addition of these five sources more than doubled the amount of data from Category 2 sources in
NUCLAR.R
Category 3- Sources that list only ftilure rate estimates. Six representative sources were
used in this project. Many more such sources exit. The six were chosen to represent a
variety of industries.
All of the sources used in this project are listed in Table 2.

3. AGGREGATION ROUTINES
As discussed in Section 2 of this report, sources of data were grouped into three categories,
depending upon the type and quality of information presented. For a given component and ftilure
mode, several sburces within a category might have failure tiormation. Also, a single source may
contain several sets of failure data. Therefore, aggregation routines are needed to combine the
information from the different sources to obtain a representative result. Two different aggregation
routines were used:
,
1.
Combining actual failure data (failures and component exposure hours or
Demands) from different sources (used for Categories 1 and 2).
2.
Combining failure rate estimates that also include error factor estimates (used
For Category 3).
For Categories 1 and 2, the aggregation procedure is as follows*:
1.
Compute Rand R2from source datai
Where &= number of failures from source i
Ti = component exposure time (h) from source i.
2.
Match moments to obtain underlying normal distribution:
M = 2 in(R) -0.5 ln(RJ
S2= ln(RJ-21n(R).
3.
Determine mean and error factor of lognonnal distributiorx
Mn = exp(lvl + S2/2)
EF = exp(l.645 S)
where Mn =ean
EF = error factor (95th percentile/50th percentile).
For data involving demands rather than exposure hours, the same equations apply, bit
With Ti replaced by Di (number of demands from source i). If tie procedme described .
above resulted in an error factor greater than 10, the error factor was chosen to be 10.

Three special cases may arise when aggregating actual failure daa such that the above routine does
not work.
The first is the case where only one data set is available (number of ftilures and number of hours or
demands). In this case a Bayesian update of a non-informative prior was used to determine the mean
Estimate 3!
Mn = (2n + 1)/(2T)
(for time-related data)
Mn = (2n + 1)/(2D + 2)
(for demand-related data).
In both cases, an error factor of 10 was used. The error factor of 10 w& chosen by examining the
aggregated results in Tables 3 and 4 and calculating an average error factor.
The second special case occurs when all of the data sources involve zero or one ftilure. In
this case, the data were combined (failures added and exposure hours or demands added) to obtain
one data set which was then treated similarly to the case just described.
Finally, the third case arises when S2is less than zero. This case was treated the
same as the second special case.
For Category 3, the aggregation routine is the followin<7:

Some of the Category 3 sources do not list error factors. In such cases, an error factor (3,5,
10, or 30) was assumed based on an average of error factors from the other sources. If no sources
listed an error factor, then 10 was used. Also, if the aggregation resulted in an error factor greater
than 30, then the error factor was assumed to be 30. Finally, if a single source listed several fbilure
rate estimates, then the estimates for that source were aggregated using the procedure described
above. Then the result for that source was combined with the other sources.
Because a goal of this project was to base component ftilure rate estimates on actual failure
data (contained in Categories 1 and 2) wherever possible, and because the quality of data in
Category 1 sources is expected to be better than that for Category 2, aggregations were pefiormed
only within categories. Results from each category aggregation were not combined to obtain an
overall result.
4. DATA SEARCH
Results of the search for component failure tiormation are sunimarized in Tables 3 through
5. Tables 3a through 3f present the Category 1 data by component failure mode, and type of
system. The NUCLARR1 column in Tables 3a through 3f actually represents the aggregation-of all
of the Category 1 sources in FKJCLARR. Tables 4a through 4f present the Category 2 results, and
Tables 5a through 5t the Category 3 results. Also presented in each table are the aggregated results
(mean failure rate and error factor).

5. RECOMMENDED RESULTS
Recommended component generic ftilure rates are presented in Tables la through lf. The
recommended results were obtained from the Category 1 aggregation, if such data existed. If not,
then the Category 2 results were used. Finally, if neither Category 1 nor Category 2 itiormation
were available, then the Category 3 results were used. Also, because the product of this effort is a
generic database, the mean frequencies were rounded off to 1,3, or 5 times the appropriate power of
10. Error factors obtained from the aggregation process were rounded off to 3, 5, or 10. Tables 6a
through 6f contain more detailed notes concerning the selections of recommended ftilure rates.
A review of Tables 6a through 6f indicates that approximately 75% of the recommended
failure rate estimates are based on actual failures from nuclear power plants or other types of
facilities. The remaining 25% of the estimates had to be generated from sources listing only ftilure
rates.
It should be noted that failure data may be reflective of a pa.xticular application or
environment. In cases where data is limited to sources of specialized application or operating
environments, it may be appropriate to modi@ the recommended mean to account for alternative
conditions. In all cases, engineering judgment should be used in the application of generic data.
Also listed in Tables la through If are identifiers such as PIP-LE-W for each of the
systern/component/fhilure mode ftilure rate distributions. In the identifier, the first three letters, PIP,
indicate the type of component, which is a pipe. The second set of letters, LE, indicates the ftilure
mode, which is external leakage. The final letter, W, indicates the type of system, which is a water
system. Tables 7, 8, and 9 list the codes used for components, ftilure modes, and processing fluids.
Parts of this naming scheme were obtained from the report Review and Development of Common
Nomenclature for Naming and Labeling Schemes for Probabilistic Risk Assessmen~8. However, in
some cases the naming schemes for components and failure modes, recommended as standard
practice in Reference 38, were changed ~o allow for a more consistent approach. Also, many
additional components had to be added.

6. APPLICATION GUIDELINES
Guidelines on application and use of failure rate dati
I. Time Dependent Failure Rate ( A )
For a normal operating facility component failure is essentially a random process and the
failure rate k, is treated as a constant. However, in the total life cycle of the facility, Z takes up
different values for its three distinct phases (the famous ‘Bathtub’ profile). For the initial ‘infant
mortality’ phase, A decreases with time, then remains constant during the normal steady state
operation phase and finally increases with time in the ‘aging’ phase. The initial phase is of minimal
importance in risk studies, but the ‘aging’ phase is relevant for many older facilities like SRS.
Failure probabilities in the random steady state phase is adequately predicted by the Exponential
model with constant h. However, ftilures in the ‘aging’ process are better estimated by the
Weibull distribution
P(t) =1- e** -( t/q )** ~, where, q is the scale or reliability parameter (- l/X.), and
~ is the shape parameter, 1< ~ <4
(for ‘aging’ phase).
As a simplification, studies indicate that exponential approximation with a ‘modified’ 1 (
fixed at 30% to 50’%higher than the ‘nominal’ A) appears to yield reasonably good results
especially in the time range of 1 to 2.5 MTBF (Mean Time Between Failure= 1/2.). In the time
period beyond 3 MTBF, Weibull distribution is recommended for failure probability determination.
Note: Sensitivity studies performed with Exponential model (with ‘modified’ k = 1.3 to 1.5
times ‘nominal’X) and Weibull model (with 1< ~ Q, range of interest for most facilities like
SRS), document the validity of the above assertion.
II.
Failure on demand ( X~) and Conversion Factors to Hourly Failure Rate (1)
Component ftilure rates are sometimes specified in per demand (typically, fails to start or
operate on demand, eg. diesel generator) rather than per time period (hour etc.). However, an
MTBF value for components is required for Risk/ RAMI analyses. The MTBF can be
expressed as the reciprocal of the hourly ftilure rate k, ie. MTBF = l/A. But a demand
failure probability &must first be changed to an hourly failure rate h before it can be
converted to MTBF. This can be done by assuming that the time period between successive
equipment demands is one day and then dividing Xdby 24 hours. This results in a hourly
failure rate that can be converted to MTBF as noted earlier. However for many standby
equipments the period between successive demands ranges from 1 to 3“months or sometimes
even to a year or more. Thus the assumption of daily demand period is quite conservative for
. .
many applications.
9
WSRC-TR-93-262,
Rev.1
Based on engineering judgement and expert opinion the following conversion factors are
recommended for use with standby equipment with varying demand frequencies:
.
Recommended Frequency for Analysis
Hourly,
1 per hour
Daily, 1 per 24 hours
Weekly, 1 per 7*24=168 hours
Observed Demand Frequency
1 or more per day
linlto3months
1 or 2 per year
Note: Demands on standby equipments are triggered by some anticipated failure events ( eg.
power supply failure for diesel generator demands). The above recommendation is based on
an uncertainty factor of -25 (ie., EF=5 ) which is considered a reasonable spread for most
anticipated events. When no reliable observed data is available for a facility, “anuncertainty
factor of -100 (ie., EF=1O) may be used with the assumed frequency for analysis. For
example, for an assumed frequency of 3 per year, the recommended frequency would be
(3/365)*100 = 1 per day (i.e.,daily).
III.
Credits for Maintenance Programs
Improvements in component reliability can be obtained with reduction in un-scheduled /unanticipated component repair/ ftilure through improved maintenance programs.
a) Preventive Maintenance (PM)
Under this maintenance program components are replaced or repaired to their original
performance level every ~ years, instead of letting them remain in place until failure.
Replacement of components ahead of their MTBF improves reliability (ie. the
probability that an item will operate without failure over some specified mission time)
which can be expressed as follows:
Reliability R(t) = e**-M
for t< T,
= e**-~*T for t 2 T,
no~al reliability equation
where T is the replacement time interval
b) Predictive/Precision Maintenance ( PdM/Pc~
PdM involves monitoring of SSC’Sthrough non-intrusive tests/ inspections to detect
component degradation and to identi$ potential problems and is a valuable tool in
preventing ftilure. Some”commonly used PdM technologies are:
Vibration Monitoring and Diagnostics,
Infhred Thermography,
Lubricating oil analysis, Ferrography and Grease analysis,
Acoustic/ Ultra-sonic tests,
Radio Frequency monitoring, Polarization Index etc. “

“
WSRC-TR-93-262,
Rev.1
These technologies have been credited to significantly reduce component failure rates
and improve reliability here at SRS as well as at other facilities.
Precision Maintenance (PcM) program at SRS utilizes Root cause Analysis technique to
all significant incidents to better define and apply PdM technologies to suit specific
components and applications.
A 50% to 75’% reduction in component failure rates has been observed in system/
facilities with successfid PdM/ PcM program. This corresponds to a 4 to 2 increase in
MTBF.
Iv.
Uncertainty and Error Factor (EF)
The choice of the value of Error Factor (EF) is highly significant due to its influence
on the value of the Mean which is the most commonly used parameter in risk analysis.
The maximum value of the Error Factor (EF) applicable to ftilure rates in this document has
been limited to 10. This coxesponds to a data spread QK95’Yo/
X05’XO)
of 100 with a Mean
bounding 76% of the population at 2.6 times the Median (X50%). A higher EF of 30.(used “
in earlier version of the document) would make the data spread -1000 with the Mean
bounding only 80V0(a marginal improvement of 4% from the 76%) of population at a
considerably higher value of 8.3 times the Median value.
An EF value in excess of 10 would normally reflect poor samples with no well-defined
distribution. Choosing a higher median value coupled with a smalIer EF might be a better
approach for such sample distributions than a lower median value with a larger and less
meaningful EF. The EF value of 30 in the original issue of the document (primarily for the
rupture mode of ftilure) was arbitrarily chosen for conservatism with no hard data to
backup. In fact, even for the rupture failures, the observed EF’s in the data tables were in
most cases equal to or below 10. A review of some independent PRA reports of nuclear
plants ( eg., Oconee, Seabrook etc.) also indicated that in less than 1% of cases EF exceeded
10. Hence an upper limit of 10 for EF is deemed more reasonable.

Use of only SRS HistoricalData (with no additionaldata source availatde)
When using sorts of events from SRS incident databank as the only source for computing
component failure rates/ fi’equencies, the following table (based on Ref. 27,40) provides the ~
appropri~ multiplier R to obtain either the 95% upper-bound failure rates (AJ for the
preferred conildence limit ( based on clm-sical conlldence interval property) or the 50%
median failure rates ~

It is recommendedto use 95% coni%lence limit values ( column 2) for conservative analysis
of acute events and 50% limits ( column 3) for realistic analysis of chronic events.
Not& This method is suitable when historical data provides only the number of occurrences
and time intends of the events and not any further detailed information.
Bayesian Update
Using a Bayesian Update technique, additional available generic data on component
failures(as found in lEEB-Std-500, Ref.-3l) can be utilhd together with SRS incident
databank (or any other facility or site-specific) information to develop more realistic failure
rates typical of a larger industrial population. Unlike the simpler classical approach
mentioned earlier for single data source, the Bayesianupdate has the capabiity to combine
“a prior” experiencewith posterior data to develop “posterio? probabilitybased on Bayes
theorem which states thaG
PosteriorProbabil@ is proportionalto Prior probability( from generic data) times
Likelihoodfiction (from Site specific data).
Appendix-B showsthe outline of BayesianUpdate model and some examples in Microsoft
EXCELspreadsheetformat.

This would the be.prefemed.methodfor data compilationand analysis to be used for fullscope PRA’s or formal Safety analysisreports.

CommonCause faihue - ~ factor
Dependentfailures such as common cause failures at the systemslevel are treated either
explicitlyby means of identifjhg causes of dependentfailure and by incorporatingthem
explicitlyin the systemsor event sequencemodels, or implicitlyby using certain parameters
to accountfor their contributionto the systems’unavailability.Examplesof the fmt type are
sharing of commoncomponents,fires, floods etc. The discussionhere deals with the second
type, which includesfailuresthat are not coveredin the fmt typebut are occasionallynon- “
random,that is, dependent.Examplesare design errors, constructionerrors, procedure
deficiencies,and unforeseenenvironmentalvariations and certain types of human error
during test and maintenance,etc. The parametricmodel used to quantifythe effect of this
secondcategoryis known as the &factor method. The parameter ~ is defined as the ffaction
of the total componentfailure rate attributableto commoncause failures
~ = itd (k + M ) = WA
where k= component’sdependentfailure rate
Xi=component’sindependentfailure rate
A = Component’stotal failure rate
So that, k= ~L and M= (1-~)k and 0S ~ S 1
