. The purpose of this test is to verify ths full stroke capability of the Safety Injection Accumulator Discharge Check Valves,
[251S*141, 142, 145, 147, 148, 151), in accordance with ASME Section XI, Subsection !WV 3520. This test also verifles in Appendix D, the remote position indication for the Safety injection Accumulator Nitrogen Makeup Valves, [2GNS* SOY 853A, B, C), the Bypass Nitrogen Supply Valves [2GNS*SOV853D, E, F], the Nitrogen lleader Vent Isolation Valves (2GNS*SOV854A, B) and the Nitrogen Makeup Outside Containment Isolation Valves [2GNS*A0V101 1, 2) to satisfy ASME XI, Paragraph IWV-3300 .equirements.

!!. GENERAL TEST HETHOD Vhile monitoring pressurizer level and accumulator pressure and volume, the S! accumulators are blowndown, one at a time, by stroking open th6 in, "alves.
The data obtained for each accumulator is then analyzed to verify proper check valve operation, by comparing the plot of the actual accumulator pressure vs. time to the calculated theoretical curve; and by Comparing the actual flow rate to the calculated minimum flow required to full-stroke open the check valves. l l ISSUE 1 REVISION 1 i' ( s
