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 Arkansas Nuclear One.
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 Stephenie Pyle at 479.858.4704.
I declare under penalty of perjury that the foregoing is true and correct. Executed on June 10, 2011.
Sincerely, Original Signed by Christopher J. Schwarz CJS/nbm
