NRC Bulletin 2011-01, Mitigating Strategies, dated May 11,2011 Letter Number 2.11.038

Dear Sir or Madam:

On May 1.1, 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 Pilgrim Nuclear Power Station (PNPS).

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 Mr. Joseph R. Lynch, Licensing Manager, at 508-830-8403.

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, Robert G. Smith PE Site Vice President

PNPS Letter 2.11.038 Page 1 of 2 QUESTION 1 Is the equipment necessary to execute the mitigating strategies, as described in your submittals to the NRC, available and capable of performing its intended function?

RESPONSE

The strategies required by section B.5.b of the Interim Compensatory Measures Order EA 026 and implemented pursuant to a license condition were submitted to the NRC by references

[1, 2, 3, 4, and 5] and reviewed and accepted by the NRC in reference [6].

Entergy assessed the status of equipment necessary to execute the mitigating strategies as identified in the referenced letters. Based upon the assessment, the equipment is available and capable of performing its intended function.

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?

RESPONSE

Entergy assessed the capability to execute the mitigating strategies as identified in the referenced letters. NRC Temporary Instruction (TI) 2515/183 Inspection Reports references [7 and 8] identified areas for strategy improvements. These issues were entered into the corrective action program. Additional enhancements and validation of those actions are ongoing and are expected to be completed by July 31, 2011.

Based upon the assessment and actions taken to date, the guidance and strategies are capable of being executed considering the current configuration of the facility, staffing, and skill levels of the staff.
