PVNGS UNITS 1, 2 AND 3 I.
Potential Problem Four (4) Target Rock Valves procured by Combustion Engineering (CE) and delivered to PVNGS were returned to CE for additional qualifi-cation testing in accordance with NUREG-0588. For this program, two (2) one-inch (1") Target Rock Model 77L-001 and two (2) two-inch (2") Target Rock Model 77L-003 Solenoid Valves were received. These Valves were intended for use as the Safety Injection Tank Vent Valves (Model 77L-001) and as the Pressurizer Auxiliary Spray Valves (Model 77L-003).
Inspections conducted prior to the test programs as well as the results of the test program itself revealed a large number of anomalies including:
a.
Insulating Washer Incorrectly Installed b.
0-Ring Seals and Rubber Grommets Missing c.
Electrical Short in the Solenoid Leads d.
Lead Wires Damaged e.
Valve Unable to Seat Properly Due to Soft Seat' Ring Coming Out of Retention Groove f.
