FNP NFPA 805 LAR Submittal Overview March 19-21, 2013 Circuit Analysis
Summary
- Circuit Analysis Process and Controls
- A l t Qualifications Analyst Q lifi ti
- Governing Analysis Criteria
- Circuit Analysis Database
- Associated Circuits Circuit Analysis Slide 2 of 14
Process and Controls
- Performed IAW approved procedure
- Strict and formal analysis conventions
- Emphasis on consistency and standardization
- Integrated PRA and NSCA requirements
- Rigidly defined Function States
- Independent verification for each analysis
- Detailed documentation in database (FDM/ARCPlus)
Circuit Analysis Slide 3 of 14
Analyst Qualifications
- All analysts formally qualified to SNC &
Contractor QUAL CARD for independent work
- Internalized industry lessons learned on training, qualifications and oversight qualifications,
- Procedure and database established to force consistency
- Maintained awareness of dual use - PRA and NSCA Circuit Analysis Slide 4 of 14
Governing Criteria
- Initial Work to Rev.1
- Gap analysis performed to Rev. 2 (per Generic RAI 10 and RG 1.205)
- Later work
- Integrated emerging PIRT issues
- No N creditdit ttaken k ffor off-scheme ff h exclusions l i
- Included Open p circuits Note: Integrated requirements for conservative, but universal criteria between PRA and NSCA Circuit Analysis Slide 5 of 14
NSCA vs. PRA
- 95% of circuit analysis y criteria for PRA and NSCA are the same
- Establish single dataset for criteria to assure dual use and better interface between NSCA and PRA
- Provide procedure and database flexibility to accommodate the 5% difference
- Long Long-term term configuration control extremely difficult if redundant data sets are maintained
- Differences p primarily y handled through: g
- Interlock identification and documentation Circuit Analysis Slide 6 of 14
Analysis Methodology
- All circuit analysis drive by FUNCTION STATES
- Component + Initial State + Desired State
- Permits maximum flexibility to accommodate PRA and NSCA differences (primarily auto signals)
- Minimize false failures up front
- Efficient Effi i t and d lless error prone
- Consistent with NUREG/CR-6850 methods for Tasks 3&9 Circuit Analysis Slide 7 of 14
Analysis Methodology, cont
- Work package development to facilitate process
- Single, controlled database (FDM)
- Process and techniques based on NRC/EPRI training g modules
- Major Steps Prerequisites q satisfied
- Function state established
- Plant specific rules and conventions
- Resolve questions Circuit Analysis Slide 8 of 14
Analysis Methodology, cont
- Major Steps Work Package g Development p
- Supplemental information Cable Selection
- All scheme cables dispositioned
- Fault codes applied to all cables
- Basis documented for excluded cables
- Selection of required cables with hot probe method
- Cables generally excluded based only on design features at this stage (NUREG/CR-6850 concept)
Circuit Analysis Slide 9 of 14
Analysis Methodology, cont
- Major Steps Power Supply pp y Identification
- All Power Supplies identified
- Required and not-required determined based on Function State requirements
- Sensitive to alternate PS lineups and how they are credited Dependencies & Interlocks
- All circuit interlocks formally dispositioned
- Equipment dependencies established or off-scheme cables directly incorporated
- Differentiate auto functions so NSCA and PRA can apply as credited by Basic Event Circuit Analysis Slide 10 of 14
Analysis Methodology, cont
- Major Steps Documentation
- Controlled database, with individual analysis originate and check sign-offs
- Final calculation for circuit analysis and PRA Notebook Circuit Analysis Slide 11 of 14
Circuit Analysis Database Circuit Analysis Slide 12 of 14
Associated Circuits
- Consolidated calculation
- Addresses NSCA & PRA
- Addresses secondary fire concerns
- Addresses loss of DC control power to Switchgear
- Followed PIRT recommendations
- Followed NEI 00-01, Appendix B method Circuit Analysis Slide 13 of 14
