30-Day Response to NRC Bulletin 2011-01, Mitigating Strategies Entergy Nuclear Operations, Inc.,
Palisades Plant Docket No. 50-255 License DPR-50
Reference:
NRC Bulletin 2011-01: Mitigating Strategies, dated May 11,2011
Dear Sir or Madam:
On May 11, 2011, the NRC issued the referenced Bulletin 2011-01, and requested a written response within 30 days. Attached is Entergys 30-day written response for the Palisades Plant.
In response to the events on September 11, 2001, and NRC requirements, Entergy developed preplanned strategies and implemented guidance to maintain or restore core cooling, containment, and spent fuel cooling capabilities under the circumstances associated with the loss of large areas of the plant due to fire or explosions. Following the events on March 11, 2011, at the Fukushima Daiichi Nuclear Power Station, Entergy took actions to ensure availability of these capabilities. The attached response reflects these actions.
There are no new commitments contained in this submittal.
If you need any additional information, please contact Ms. Barbara E. Dotson, Acting Regulatory Affairs Manager, at 269 764 2265.
I declare under penalty of perjury that the contents of this response are true and correct to the best of my knowledge and belief. Executed on this 10th day of June 2011.
Sincerely, Thomas P Kirwin Acting Site Vice President
