| | * RA-Sa-2009 Supporting Requirements met to Capability Category II except: |
| | - Some sub-elements of SY-C1, SY-C2 System Notebook Documentation need completion |
| | * To be completed prior to RICT Program implementation 19 |
| | |

| | * Common Cause treatment will be in accordance with NEI 06-09-A or Regulatory Guide 1.177 Rev. 1 23 |
| | |
| | Plant Modifications |
| | * PRA models rely on installation of modifications or taking compensatory measures |
| | * RICT Program will not be implemented until modifications complete or compensatory measures in place |
| | * FLEX strategies not yet reflected in the PRA models - conservatism 24 |

- Miscellaneous variances described in LAR 11
TS 3.4.12, Pressurizer Vents
- RICT added to Two Required Actions
- Note added to preclude use of RICT when all pressurizer vent paths are intentionally made inoperable 12
Pressurizer Vent Paths S RCB-HV109 RCA-HV106 S To Containment RCB-HV108 Atmosphere S S S RCA-HV103 RCB-HV105 Reactor Drain Tank Pressurizer 13
TS 3.7.3, Main Feedwater Isolation Valves (MFIVs)
- LAR adds restoration action
- RICT added to Two Required Actions 14
Miscellaneous Variances
- TS 3.7.2, Main Steam Isolation Valves (MSIVs)
- Did not add RICT for restoration conditions associated with MSIV actuator trains
- TS 3.7.4, Atmospheric Dump Valves (ADVs)
- Note added to preclude use of RICT when all ADV lines are intentionally made inoperable
- TS 3.7.9, Ultimate Heat Sink (UHS)
- Added new 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> restoration condition for UHS
- TS 3.8.7, Inverters
- Revised note since PVNGS design has two inverters per train supporting 4 channels of vital instruments
- Note precludes use of RICT for two or more inverters intentionally made inoperable resulting in a loss of safety function 15
Summary
- LAR to remove Second Completion Time (TSTF 439) in progress
- Monitoring TSTF 505 Operating Experience
- Participating in Industry Committees
PRA Models Everett DePue Senior Engineer PRA Lead for TSTF-505
Summary of PRA Models
- PRA models developed and peer reviewed
- Internal events
- Internal flood
- Internal fire
- Seismic
- RG 1.200 Rev. 2 hazards screened and peer reviewed
- Total CDF/LERF meet RG 1.174 Rev. 2 limits
- Internal events and internal flood risk very low
- CDF/LERF dominated by internal fire and seismic hazards 18
Internal Events PRA
- Peer review by CEOG conducted in 1999
- Self-assessment performed against entire RA-Sa-2009 in 2015
- RA-Sa-2009 Supporting Requirements met to Capability Category II except:
- Some sub-elements of SY-C1, SY-C2 System Notebook Documentation need completion
- To be completed prior to RICT Program implementation 19
Internal Flood PRA
- Industry Peer Review conducted in 2010
- All ASME/ANS PRA requirements met to Capability Category II after peer review findings addressed 20
Internal Fire PRA
- Fire PRA complies with methods in NUREG/CR-6850
- Industry Peer Review conducted in 2012
- Follow-up Industry Peer Review conducted in 2014 - addressed 2012 findings
- All ASME/ANS requirements met to Capability Category II after peer review findings addressed 21
Seismic PRA
- Industry peer review conducted in 2013
- All ASME/ANS requirements met to Capability Category II after peer review findings addressed except
- SPR B7 Complementary Success Logic
- Meets Capability Category II for ASME/ANS RA-Sb-2013 22
Plant-Specific Modeling
- Real time risk model as currently used for existing Technical Specification CRMP OR
- Pre-solved solutions (STP approach)
Plant Modifications
- PRA models rely on installation of modifications or taking compensatory measures
- RICT Program will not be implemented until modifications complete or compensatory measures in place
- FLEX strategies not yet reflected in the PRA models - conservatism 24
Summary
- All hazards have been evaluated in accordance with RG 1.200 Rev. 2
- All PRA models peer reviewed
- Capability Category II met for all PRA models with three exceptions
Implementation Plan Bryan Thiele Department Leader Risk Informed Project Manager
Implementation Plan
