COLUMBIA GENERATING STATION, DOCKET NO. 50-397 ENERGY NORTHWEST'S INITIAL STATUS REPORT IN RESPONSE TO MARCH 12, 2012 COMMISSION ORDER MODIFYING LICENSES WITH REGARD TO RELIABLE HARDENED CONTAINMENT VENTS

Reference:

1. NRC Order Number EA-1 2-050, Order Modifying Licenses with Regard to Reliable Hardened Containment Vents 2. NRC Interim Staff Guidance JLD-ISG-2012-02, Compliance with Order EA-1 2-050, Reliable Hardened Containment Vents, Rev 0, August 29, 2012

Dear Sir or Madam:

On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued the referenced Order (Reference

1) to Columbia Generating Station (Columbia).

Reference 1 directs Columbia 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 Attachment 2 of Reference

1. Full implementation is required no later than either two refueling cycles after submittal of the overall integrated plan or by December 31, 2016, whichever comes first.Reference 1 requires submission of an initial status report 60 days following issuance of the final interim staff guidance.

The purpose of this letter is to provide the initial status report pursuant to Section IV, Condition C.2, of Reference 1 within 60 days following issuance of Reference

2. This report confirms Energy Northwest, the licensee for Columbia, has received Reference 2 and is in the process of evaluating the guidance for the purpose of having a 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 SBO as described in Attachment 2 of Reference
