Risk Analysis y
- Objectives for this section
- Summarize PRA Model Scope and Quality
- Describe the Risk Assessment
- Discuss the Sensitivity Analyses
- Discuss the Configuration Risk Management Program and Risk Reduction Measures
PRA Model Scope p and Qualityy
- Internal Events and Internal Flooding models were developed per RG 1.200 Rev 2 requirements and have been Peer Reviewed Per the Peer Review Team Overall, the CPNPP PRA was found to substantially meet the ASME PRA Standard at Capability Category II and can be used to support risk riskinformed informed applications applications
PRA Model Scope and Quality
- Subsequent q to the Peer Review, Findings g and Observations were addressed and incorporated into the current Revision 4A model All Not Not Met Met now Cat II or better 4 of 7 previous Cat I now Cat II or better Remaining 3 with no application impact All Findings were resolved and incorporated All but one suggestion incorporated One was deferred with no application impact All remaining SRs meet Cat II or better
- External Events based on IPEEE and will be used for insights only
PRA Model Scope and d Quality li
- Adequately addresses asbuilt, asoperated plant
- Plant specific data and plant specific best estimate TH address success criteria
- Loss of Offsite Power modeling is robust
- Electric power systems modeling is robust; Alternate Power Generator is installed and modeled in the PRA
- SBO / RCP Seall LOCA modeling d li isi robust b and d uses the h WOG 2000 modeld l with high temperature seals
- Convolution method used for LOOP recovery analyses
Description of Risk Assessment
- Applicable pp Guidance and Criteria
- Q Quantitative tit ti A Analyses l for f IInternal t l Events E t and d Fl Flood, d Level I and II
- Qualitative Analyses for External Events
- Qualitative discussion combined with IPEEE risk insights for the Fire, High Winds (Tornado), and Seismic (Margins)
- Supported by detailed walkdown of plant
Discussion of Sensitivity Analyses
- Sensitivity studies are used to address uncertainties.
These studies will include but are not limited to:
- Reliability of components important to the risk contributions of the CT extension
- Increased I d duration d ti off XST1 CT
- LOOP Weather and Plant Centered frequencies
- Deferred maintenance
- Uncertainty analysis will be performed per NUREG 1855.
855.
- Common Cause Failure discussion
Configuration Risk Management Program
- CPNPP has a Configuration Risk Management Program
- Incorporates the characteristics of the model Configuration Risk Management Program described in RG 1.177
- CRMP description has been incorporated into plant Technical Specifications - 5.5.18 5 5 18
- Previously approved for one time 14day change to Technical Specifications for AC Sources - Operating - B 3.8.1 Required Action A.3 (XST2A transformer installation)
- CRMP is a requirement off the h Maintenance Rule l Program.
CPNPP endorses the guidance in NUMARC 9301, Industry Guideline For Monitoring the Effectiveness Of Maintenance At Nuclear Power Plants Plants
- CPNPP will meet the fire (a)(4) requirement by December 1, 2013
Configuration Risk Management Program -
Risk Mitigation Actions
[Implemented during the extended CTs]
- 1. Restricted Access to and Suspension of Maintenance in the Switchyard.
- 2. Testing of Diesel Generators (EDG and APG) and Turbine Driven Auxiliary Feedwater Pumps within the Two (2) Weeks Prior to the Start of the XST1 extended CT.
- 3. Rescheduling of Testing and Maintenance on the EDGs, APGs, TDAFWPs, XST2, CCWPs and SSWPs to occur outside the extended CT window.
- 4. Suspension of Hot Work Activities Near XST2 Power and Control Cabling.
- 5. Roving Hourlyl Fire Watch h Along l Paths h off XST2 Power and d Controll Cabling.
bl
- 6. Selection of Time of Year Due to Weather Considerations.
- 7. Operations preparations and grid monitoring during the CT.
Preliminary Conclusions of Risk Assessment
- Based upon previous LAR submittal and the current update to the PRA model, model the preliminary PRA results show that the extension of the XST1 CT will have minimal impact on plant risk
Proposed Schedule Luminant Power requests approval of the proposed License Amendment by September 30, 2013, to be implemented within 120 days of the issuance of the license amendment.
