==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 Entergy's 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
