COLUMBIA GENERATING STATION, DOCKET NO. 50-397 COMMITMENT TO MAINTAIN SEVERE ACCIDENT GUIDELINES
Dear Sir or Madam:
The Nuclear Energy Institute (NEI) Nuclear Strategic Issues Advisory Committee (NSIAC) recently approved an Industry Initiative to implement and maintain Severe Accident Guidelines (SAGs). By this letter Energy Northwest establishes commitments related to SAGs for Columbia Generating Station (Columbia). These guidelines would be used by emergency response personnel during accident conditions that progress beyond the mitigation capabilities described in Emergency Operating Procedures (EOPs). SAG strategiesare intended to arrest the progression of fuel damage, maintain the capability of the containment as long as possible, and minimize radiological releases. The new SAG commitments are listed in Attachment 1.
It is expected that NRC staff personnel will conduct periodic inspection of our SAGs and perlormance deficiencies, if any, will be assessed using the Reactor Oversight Process (ROP). We also understand that inspection activities will not extend to NRC review and approval of SAG strategies, or the use of equipment described in the SAGs.
If you should have any questions regarding this submittal, please contact Ms. L. L.
Williams, Licensing Supervisor, at 509-377-8148.
I declare under penalty of perjury that the foregoing is true and correct.
