RAIs for Columbia Relief Request RAI (MF8925), 3ISI-19 Importance: High

Lisa, By letter dated December 7, 2016, (Agencywide Documents Access and Management System (ADAMS), Accession No. ML16343B035), Energy Northwest (the licensee), submitted Request for Relief No. 3ISI-19 from certain requirements of the American Society of Mechanical Engineers, Boiler and Pressure Vessel Code (ASME Code),

under the provisions of Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Section 50.55a(g)(5)(iii), for the third 10-year inservice inspection (ISI) Program for the Columbia Generating Station. The licensees request for relief applies to the third ISI interval, in which the licensee adopted the 2001 Edition through the 2003 Addenda of ASME Code Section XI as the code of record.

The NRC staff has reviewed the relief request and has identified areas where additional information is needed to complete its review. A clarification call was held on September 5, 2017 to finalize the text of the questions below. These RAIs are now released formally with a 30 calendar day response time from today of October 6 2017.

RAI 1

Section XI, Article IWA-2220 of the ASME Code specifies the requirements for surface examinations.Section XI, Article IWA-2221 of the ASME Code requires that surface examinations performed using the magnetic particle method shall be conducted in accordance with Section V, Article 7 of the ASME Code. Please provide the applicable Code requirements for the surface examination of the Category C-C attachment welds (e.g.

ASME Code Section V, Article 7.)

RAI 2

The licensee states that the A RHR system is subject to VT-2 visual examination during system pressure testing and that there were no recorded leaks during these pressure tests last interval. Since the Category C-C attachment welds are not pressure boundary welds, please explain how the system pressure test is relevant to determine the acceptability of the four Category C-C attachment welds.
