Title: MANAGEMENT REVIEW MEETING


1
A Brief History of CM in the Nuclear Industry
and the CMBG
Presented By Keith Reinsmith CMBG Steering
Committee June 21, 2010Charlotte, North Carolina
2
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)

3
A Brief History of CM in the Nuclear Industry
  • DOE STD 1073-93 Configuration Management
  • Applicable to DOE nuclear facilities in the
    operational phase.

4
A Brief History of CM in the Nuclear Industry
  • Nuclear plants in mid 60s to early 80s
    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

5
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

6
A Brief History of CM in the Nuclear Industry
  • Salem ATWS event (1983)
  • Generic implications identified in NUREG-1000 and
    NRC Generic Letter 83-28
  • compliance with vendor recommendations
  • part and procurement issues
  • vendor manual controls
  • Industry initiatives by INPO, NUMARC and EPRI to
    provide guidance and consistency

7
A Brief History of CM in the Nuclear Industry
  • 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
    self-evaluation
  • NUREG-1397, NUMARC 90-012, INPO 87-006 and
    NUREG/CR-5147

8
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

9
A Brief History of CM in the Nuclear Industry
  • NRC specialized SSFIs for safety systems
  • Electrical Systems (EDSFI)
  • Service Water Systems (SWOPI)
  • SECY-92-193 intent to issue generic letter to
    require utilities to address how they were
    dealing with the problems - withdrawn

10
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
  • PP02-1994 Position Paper on Configuration
    Management Program

11
The Configuration Management Benchmarking Group
is Born
  • First Nuclear CM benchmarking conference hosted
    by PPL Susquehannain Fall 1994
  • Forum to exchange informationon CM processes and
    methodsat 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

12
The CMBG Idea Grows
  • Interest from industry to hold another similar
    conference
  • Second conference hosted byOntario 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

13
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.

14

17
A Brief History of CM in the Nuclear Industry
  • Millstone Spent Fuel Pool Cooling (1996)
  • NRC had lost confidence in utilitys 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

18
A Brief History of CM in the Nuclear Industry
  • 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

19
A Brief History of CM in the Nuclear Industry
  • 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.

24
A Brief History of CM in the Nuclear Industry
  • INPO - Margin Management (2003)
  • INPO reorganization emphasized, Evaluating
    Configuration and Margin Management

Functional/Design Failure
Greater than design basis range
Design margin
( This is a prohibited range of operation and
represents the additional conservative margin to
account for uncertainties in design and
construction )
Design or Tech Spec Basis Limit
Analyzed transient range
( 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)
Operating Point Limit
Operating margin
Allowed operating range
( The allowed operating range provides the normal
margins operators use without violating setpoints
)
Normal Operating Point

32
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
