Note 1: Pnmary Contamment Purge and Vent 18-inch valves are identified in bold text. Due to toshng configurabons, several of the valves, wtuch are subrect of the requested licensing amendment, are tested in conjunchon with addibonal valves. Maximum allowed leakage for these test configurabons is 17.2 SCFH at a test pressure of 42 psig.

Note 2: As Found leakage test results.

'I As Left Leakage test results: after performance of correchve mantenance, preventative mamtenance, or after related actmbes that I Note 3:

could have an adverse impact on leakage performance. Lack of test data indicates no such actmties occumed for Pnmary Contamment Purge and Vent valves dunng this penod i
