A Brief History of CM in the Nuclear
Industry
• Configuration Management in military and
aerospace industry geared towards product
conformance to facilitate interchangeability of parts
while still satisfying the overall design
requirements
• MIL-STD-973 (1992), ”Configuration Management”
(later replaced by ANSI/EIA-649-1998)

A Brief History of CM in the Nuclear
Industry
• DOE STD 1073-93 “Configuration Management”
• Applicable to DOE nuclear facilities in the
operational phase.
DOE-STD-1073 was updated in
2003

A Brief History of CM in the Nuclear
Industry
• Nuclear plants in mid 60’s to early 80’s typically
designed by AEs under contract
• Final design documents typically turned over to
the utility at the end of construction
• Little knowledge transfer of design info to utility
engineering organization
• Utilities struggled to deal with long term design
maintenance and related document upkeep

A Brief History of CM in the Nuclear
Industry
• Early indicators that the nuclear plant design
basis knowledge was becoming disconnected
from the physical plant
• IE Bulletin 79-14 uncovered
• calculation discrepancies
• undocumented modifications
• document discrepancies
• as-built problems

Davis Besse Loss of Feedwater event (1985)
• Led to NRC Safety System Functional Inspections
(SSFIs) and NUREG-1154
• difficulties maintaining operational readiness of
safety systems
• lack of understanding design bases
• Voluntary design basis reconstitution, DBDs and selfevaluation
• NUREG-1397, NUMARC 90-012, INPO 87-006 and
NUREG/CR-5147

A Brief History of CM in the Nuclear
Industry
Browns Ferry (1985)
• Browns Ferry fire in Unit 1 (1975) led to changes in
NRC standards for Fire Protection
• All three Browns Ferry units shut down voluntarily in
March 1985 due to CM related problems containment isolation testing (Unit 1), reactor water
level instrumentation (Unit 2)
• Unit 1 restarted in May 2007 after 22 year shutdown

require utilities to address how they were dealing
with the problems - withdrawn

A Brief History of CM in the Nuclear
Industry
• Nuclear Information and Records Management
Association (NIRMA) CM Committee developed
solution
• control of technical information by
engineering and operations personnel
• mature records management and document
control process

The Configuration Management
Benchmarking Group is Born
• First Nuclear CM benchmarking conference
hosted by PPL Susquehanna
in Fall 1994
• Forum to exchange information
on CM processes and methods
at work in the industry
• 17 US utilities were represented
• Each utility made presentation
about their CM program
• No motivational speeches
• No sales promotions by service providers
11

The CMBG Idea Grows
• Interest from industry to hold another similar
conference
• Second conference hosted by
Ontario Hydro in 1995
• Drafted plans for continuing organization approved in 1996
• Adopted name: Configuration Management
Benchmarking Group
• Formed Steering Committee
• Wrote Mission Statement “…forum for peer-level
information sharing…”
• Defined ground rules for holding future
conferences
12

CMBG is not affiliated with any
other single organization
• Independent of regulatory and oversight agencies
• Conference costs are paid by registration fees
and supplemented by host utility
• Host utility pays for web site
• Activities limited to information exchange
• Written Principles and Practices guide our
endeavors.

• Presented elements and attributes that facilities
needed to establish of a good CM program.
• Later became basis for ANSI/NIRMA CM-1.0-2000
Criteria
• Program management
• Design requirements
• Information Control
• Change control
• Assessment
• Training

A Brief History of CM in the Nuclear
Industry
Millstone Spent Fuel Pool Cooling (1996)
• NRC had lost confidence in utility’s ability to know
and maintain its design basis and to implement
design and licensing requirements
• 10CFR50.54(f) letter in October 1996 to all licensees
that required a response on how design basis
information was controlled and maintained.
• More far-reaching implications than letter that NRC
was persuaded not to issue in 1993

Millstone Spent Fuel Pool Cooling (1996)
• 10CFR50.54(f) letter helped to solidify CMBG as a
viable resource for the industry
• Demonstrated how the CMBG "network" could be
used to find and distribute valuable CM information
between utilities, including good practices and
lessons learned

DC Cook Design issues (1997)
• Extended shutdown due to inability to respond to
design basis event and other configuration issues
• Contributed to INPO decision to modify the
evaluation performance objectives and criteria to
include configuration management and to the
formation of a new CM evaluation department.

INPO - Margin Management (2003)
• INPO reorganization emphasized, “Evaluating
Configuration and Margin Management”
Functional/Design Failure
Greater than design basis range
Design margin
Design or Tech Spec Basis Limit
( This is a prohibited range of operation and
represents the additional conservative margin to
account for uncertainties in design and
construction )
Analyzed transient range
Operating margin
Operating Point Limit
( Design allows operation in the transient range.
However operating restrictions consistent with the
design, such as the magnitude and frequency of
excursions into this range apply)
Allowed operating range
Normal Operating Point
( The allowed operating range provides the normal
margins operators use without violating setpoints )

The Next Big Thing in Nuclear CM
• We need your help in identifying the CM
issues important to your station
• CM for new plants
– CMBG is a forum for sharing lessons learned
from the current generation of operating plants
in developing CM controls/ processes for the
next generation of the nuclear fleet
• YOUR CMBG will continue to provide a
forum for industry benchmarking on CM
issues
