Dear Sir or Madam:

On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued an order (Reference 1) to Entergy Nuclear Operations, Inc. (Entergy). The Order was immediately effective and directs Entergy to have a reliable hardened vent (RHV) to remove decay heat and maintain control of containment pressure within acceptable limits following events that result in the loss of active containment heat removal capability or prolonged station blackout (SBO). Specific requirements are outlined in of the Order.

The Order requires submission of an initial status report 60 days following issuance of the final interim staff guidance (ISG). The final ISG (Reference 2) was issued August 29, 2012. The purpose of this letter is to provide the initial status report pursuant to Section IV, Condition C.2, of the Order (Reference 1) within 60 days following issuance of the ISG (Reference 2). This report confirms Entergy has received the ISG and is in the process of evaluating the guidance for the purpose of having a reliable hardened vent (RHV) to remove decay heat and maintain control of containment pressure within acceptable limits following events that result in the loss of active containment heat removal capability or prolonged station blackout (SBO) as described in Attachment 2 of the Order.

The ISG, section 4.0 contains the specific reporting requirements for the initial status report. The following information provides the status pursuant to section 4.0 of the ISG.
