INTERIM PART 21 NOTIFICATION - DEFECTIVE SOLENOID VALVES The following is a summary of information that was obtained from Flowserve via facsimile: On January 13, 2020, and January 14, 2020, two Flowserve Model 38878-8, 3-way, 2-postion solenoids valves supplied to Seabrook Station for use on the feed water isolation valve actuator failed bench testing. The failed solenoid valves were returned to Flowserve for evaluation. The evaluation of these solenoid valves will be completed by June 11, 2020. Point of Contact: Matt Hobbs, PE Engineering Manager Office: 919-334-7127 MHobbs@flowserve.com
The following is a summary of the information provided by the vendor via fax and email: Testing at Flowserve determined that valves did not reposition when actuated and were failed. Disassembly determined that one valve had unidentified foreign material that was preventing valve from actuating, and the other valve had been partially disassembled and then reassembled, resulting in damage that caused the valve to not actuate. Flowsever determined that these conditions would have caused failure of the assembly and test performed at Flowserve before the valves were shipped and therefore occurred after Flowserve shipped the valves. Flowserve concluded that these two solenoid valve failures are not defects or deviations that occurred at Flowserve that would be associated with substantial safety hazards. Notified R1DO (Jackson) and Part 21/50.55 Reactors Group (by email). |
