Subject:
Oconee's topics for next weeks drop in Preston Gillespie, Bill Pitesa, and Tom Ray will be coming for the drop-in.
Topics:
Merger overview and planned changes NFPA-805/PSW status o Bartley note - Licensee submitted an LAR on 8/1 for revision to NFPA-805 amendment to move completion date out to 12/31/2014. Current due date is 12/31/2012. Request is due to procurement delays on PSW equipment and the discovery of heatup issues in 3 areas related to the PSW modification (electrical rooms, east penetration rooms and PSW pump area). Rooms don't have cooling for PSW events. Licensee may complete prior to 12/31/2014 depending on actions necessary to resolve heatup issue.
Status of items associated with o
Flood CAL Bartley note - working with NRR to determine best way to modify CAL, licensee proposing to have analysis date and modifications (submit list of all modifications and implementation schedule) date consistent with Fukishima 50.54(0 letter. This would move the submitting list of all modifications out to August 2015. Initial staff take is that it is reasonable to have the flood reevaluation to be consistent with the 50.54(f) letter but it is NOT reasonable to move out the integrated assessment report and submitting the list of modifications to 2015 since licensee is already way ahead on this. Integrated assessment (at least for dam failure) is pretty much done. Modifications have been evaluated and should just need adjustment based on results of re-evaluation.
o SSF CAL
" Bartley note - SSF design basis reconstitution in progress. So far only significant issue has been the decay heat requirements for SSF to be operable. They need enough decay heat to maintain the plant at essentially NOT/NOP for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> for SSF operations. This has resulted in the SSF being declared inoperable on several occasions.
" Bartley note - Licensee submitted a letter documenting their evaluation of modifications/procedure changes to reduce risk due to turbine building bus duct fires.
Letter takes credit for PSW modifications to reduce risk. Letter also discusses enhancements (not commitments) for PMs on bus ducts, changing bronze bolts to stainless steel, periodic thermography). RPB I is satisfied with the actions and has drafted a letter to close this CAL item.
License Renewal inspection preparations - plan to highlight extensive efforts to prepare for inspection Progress made in conservative decision making Ultimate fix for pressurizer heater breakers o
Bartley note - these are the breakers in the east penetration rooms that are the normal power supply to the pressurizer heaters and would be used during PSW operations. Same issue we had with the pressurizer heater breakers in containment for the SSF. Problem is the heatup issue discussed under NFPA-805 bullet.
Preparations for upcoming 95002 for SSF pressurizer heater breakers.
