TELEPHONE CONFERENCE CALL COLUMBIA GENERATING STATION LICENSE RENEWAL APPLICATION August 10, 2010 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of Energy Northwest, held a telephone conference call on August 10, 2010, to discuss and clarify the following requests for additional information (RAls) concerning the Columbia Generating Station, license renewal application (LRA).

RAI B.2.49-1

Background

A review of operating experience at Columbia Generating Station (CGS) has indicated that multiple failures of small-bore socket welds have occurred at CGS due to cracking.

GALL Report,Section XI.M35 recommends the use of the One-Time Inspection of ASME Code Class 1 small-bore piping only for those plants that have not experienced cracking of ASME Code Class 1 small-bore piping resulting from stress corrosion or thermal and mechanical loading. For those plants that have experienced cracking, the GALL Report recommends periodic inspection of the subject piping to be managed by a plant-specific aging management program (AMP).

Request Since cracking of socket welds has occurred at CGS, either provide a plant-specific AMP that includes periodic inspections to manage cracking, or provide justification why a plant-specific AMP that includes periodic inspections is not necessary for ASME Code Class 1 small-bore piping.

Discussion: The staff discussed with the applicant the need for a plant-specific AMP that included a detailed description of the sampling method used in the periodic inspections.
