ANSI/NIRMA CM Standard 2021 Revision CMBG Conference - July 2022 Pittsburgh PA
History & Background of the CM Standard Approach taken for 2021 Revision Overview of the revision process Voting process and results Topics Topics Comment reviews and resolution ANSI processes & publication Overview of changes to 2021 Revision Q&A
History - 1985 to 1994: CM-related issues raised in the nuclear industry o NRC Safety System Functional Inspections (SSFIs) o Licensee difficulties finding information on SSCs o Control of Design Basis was questioned by NRC History & History & Background Background NIRMA establishes a Configuration Management Committee (CMC) in 1987 NIRMA CMC develops a Position Paper (PP02) on CM for operating nuclear plants: o Initial PP02 1989 Focus on common problems and established core CM Program elements o PP02 revised in 1994 in conjunction with DOE which had DOE Order 1073 as CM Program reference
History - 1994 to 2000: PPL sponsored initial CM Information Exchange Conference in October 1994 o Utilities shared their CM-related activities o NIRMA presented PP02 and recommended consideration for an industry standard on CM Not endorsed at the time o CMBG became official name at 1996 Conference History & History & Background Background 1996 Millstone shutdown occurred o NRC required licensees response to 10 CFR 50.54 (f) request for information with focus on CM o CMBG coordinated response and engaged NIRMA to collaborate on an industry Standard NIRMA and CMBG collaboration: o Developed initial NIRMA CM Technical Guideline (TG19) o ANSI/NIRMA CM Standard in 2000 and all revisions
History of Standard: ANSI/NIRMA Standard CM 1.0 published in 2000 First revision was published in 2007 2007 Revision was Reaffirmed in 2015 Background Background & & History History ANSI requires action on a Standard every five (5) years: NIRMA was delayed in starting 1st cycles ANSI granted extensions on action for both 2007 and 2015 versions The new revision was started in Mid-2020 so NOT LATE..!
Scope of 2021 Revision: Continue to expand CM guidance for operating plants Added Section 4 to emphasize the need for CM in full lifecycle Design through Decommissioning Approach Approach to the to the Revision Revision Focus of 2021 Revision: Updates to reflect evolving best practices Clarify US-specific terms to allow the international nuclear community to better understand the intent and meaning Add Appendices with examples to show how CM principles have been implemented in the industry
Revision process: Establish Task Team to develop the revision Collect inputs for consideration in the revision Overview Overview of of Revision Revision Process Process Develop, review and revise content Recruit industry representatives for reviewing and voting on proposed revision Conduct voting process (Ballots) Process documentation package for ANSI Finalize standard revision Publish for industry use
Revision Task Team: Laurent Perkins Bentley/Cohesive Overview Overview of of Revision Revision Process Process David Weber Energy Northwest (Columbia Station) Mike Dickson Retired Duke Energy Rich Giska R&L Partners, Inc. (ANSI Standards Liaison) Major review and feedback provided by Westinghouse CM Team
NIRMA does not vote on the revision to the CM Standard Per ANSI Requirements, the voting group is called the Consensus Body Voting Process The Consensus Body is required to include members that: Might be materially affected by the Standard Represent multiple perspectives to ensure balance of areas of interest in the voting
The Consensus Body membership: Industry Interest Groups: oINPO o CMBG Nuclear Utilities/Owner Operators Three (3) NSSS Suppliers Four (4) A/E Constructor One (1) Voting & Results The Consensus Body voting results: Approve Seven (7) Approve with Comments Three (3) Object Zero (0) Not returned Two (2)
NIRMA submitted a documentation package to ANSI for approval: BSR-9 package with evidence of voting results Any Object ballots require resolution Given no Object ballots ANSI provided approval NOTE: ANSI does not review and approve the content of ANSI Standards ANSI Process ANSI requires publication of the revised standard within six (6) months of approval Development Team reviewed comments: Determined which warranted updates Updated text for final version to be published
NIRMA did an editorial review and format scrub for final publication NIRMA Published CM 1.0, 2021 Revision in January 2022 Standard Published It is available for sale by NIRMA & ANSI ANSI/NIRMA CM 1.0 2021 | NIRMA ANSI/NIRMA CM 1.0-2021
