Dear Sir or Madam:
On April 10, 2006, the NRC issued the referenced Generic Letter (GL) to request that licensees evaluate their facilities to confirm compliance with existing applicable regulatory requirements in light of the information provided in the GL and take any appropriate additional actions. Recent confirmatory testing of the Hemyc and MT fire barriers revealed they may not perform their intended protective function during a fire.
The GL also required licensees to provide a written response, as applicable, to their facilities. The GL response is provided in the enclosure herein.
Because Energy Northwest does not rely on, and has not installed, Hemyc or MT fire barriers at Columbia Generating Station, Energy Northwest is only responding to the following requests for information from the GL:
- 1. A statement on whether Hemyc or MT fire barrier material is used at their nuclear power plants and whether it is relied upon for separation and/or safe shutdown purposes in accordance with the license basis, including whether Hemyc or MT is credited in other analyses (e.g., exemptions, license amendments, GL 86-10 analyses).
- 2. A description of the controls that were used to ensure that other fire barrier types relied on for separation of redundant trains located in a single fire area are capable of providing the necessary level of protection.
RESPONSE TO GENERIC LETTER 2006-03, "POTENTIALLY NONCONFORMING HEYMC AND MT FIRE BARRIER CONFIGURATIONS" Page 2 Energy Northwest makes no new commitments by this letter. Ifyou have any questions or require additional information, please contact Mr. GV Cullen at (509) 377-6105.
I declare under penalty of perjury that the foregoing is true and correct. Executed on the date of this letter.
