Enclosure PG&E letter DCl-11-065 Page 1 of 2 PG&E 30-Day Response to NRC Bulletin 2011-01 Mitigating Strategies NRC Question 1:
Is the equipment necessary to execute the mitigating strategies, as described in your submittals to the NRC, available and capable of petiorming its intended function?
PG&E Response 1:
10 CFR 50.54(hh)(2) requires licensees to implement guidance and strategies under the circumstances associated with loss of large areas of the plant due to explosions or fire in the following areas: (1) fire fighting; (2) operations to mitigate fuel damage; and (3) actions to minimize radiological release. The Diablo Canyon Power Plant guidelines and strategies are provided in the following primary correspondence on this topic:
(1) PG&E letter DCl-05-058, "Response to NRC Guidance Regarding Mitigation Strategies", dated May 25, 2005.
(2) PG&E letter DCl-07-001, "Response Providing Implementation Details for the Phase 2 and 3 Mitigation Strategies", dated January 11, 2007.
(3) PG&E letter DCl-07-051, "Response to NRC Request for Additional Information Regarding Implementation Details for the Phase 2 and 3 Mitigation Strategies",
dated May 8, 2007.
Equipment necessary to execute the PG&E 10 CFR 50.54(hh)(2) licensing basis mitigating strategies described in the above documents is available and capable of performing its intended function. This was confirmed by walking down equipment that is used in the performance of the Extreme Damage Mitigation Guidelines (EDMGs),
Extreme Damage Guidelines, and Extreme Damage Water Management Guidelines verify the equipment is available. In addition, applicable site mitigation casualty procedures were walked down in the same manner as the EDMGs.
NRC Question 2:
Are the guidance and strategies implemented capable of being executed considering the current configuration of your facility and current staffing and skill levels of the staff?
PG&E Response 2:
10 CFR 50.54(hh)(2) requires licensees to implement guidance and strategies under the circumstances associated with loss of large areas of the plant due to explosions or fire in the following areas: (1) fire fighting; (2) operations to mitigate fuel damage; and (3) actions to minimize radiological release. The PG&E 10 CFR 50.54 (hh)(2) licensing basis guidelines and strategies are capable of being executed considering Diablo
Enclosure PG&E Letter DCL-11-065 Page 2 of2 Canyon Power Plant's current configuration, current staffing, and skill levels of the staff.
To confirm this, the Extreme Damage Mitigation Guidelines, Extreme Damage Guidelines, Extreme Damage Water Management Guidelines, and applicable casualty procedures were reviewed and determined to be executable based on the in-plant walkdowns.
