TELEPHONE CONFERENCE CALL COLUMBIA GENERATING STATION LICENSE RENEWAL APPLICATION October 13, 2010 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of Energy Northwest (the applicant) held a telephone conference call on October 13, 2010, to discuss the following draft request f or additional information (D-RAI) concerning the Columbia Generating Station license renewa l application (LRA). Draft Small Bore Piping Program D-RAI B.2.49-2 Background LRA Section B.2.49 states that the Small Bore Piping Program is a new plant-specific program that wi ll detect and characterize cracking in small-bore piping components that are exposed to reactor coolant. In the "detection of aging effects" program element the applicant stated that in-scope components will be grouped into populations based on component type, materia l, and environment. The applicant also stated that the sample size will be 10 percent of each population (except for socket welds) with a minimum of one location and a maximum of 20 locations; the socket weld sample will include three locations.

Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants Section A.1.2.3.4 states that this program element shou l d describe "when," "where," and "how" program data are collected (i.e., all aspects of activities to collect data as part of the program).

It also states that when sampling is used to inspect a group of structures and components, a basis should be provided for the inspection population and sample size that is selected.

The applicant stated the number of socket welds to be examined as a part of the Small Bore Piping Program; however, it does not state the total number of such welds in the plant (i.e., the sample population).

The staff is unable to determine the sample size for socket welds as a percentage of the total number of such welds present to assess whether the sample size is suff i cient to be representative of the total socket weld sample population.

Reguest Provide and justify the sampling information that is selected, in terms of number of welds and percent of welds to be inspected, for the volumetric examinations of socket welds for both nondestruct i ve and/or destructive examinations.

Discussion:

The applicant understands the question and the staff will send a formal RAI. ENCLOSURE 2
