21.21(d)(3)(i) DEFECTS AND NONCOMPLIANCE PART 21 - NON-CONFORMING COVER MACHINING ON SOLENOID VALVE The following is a synopsis of the Part 21 report that was received via fax:
"Cover Machining is installed on upper section of Solenoid Valve and it allows for the electrical connection to the valve solenoid and protects inside wiring of the solenoid from environmental condition. Cover machining part number V52636-567 has 0.190 radius (Drawing V52620-50 Zone D3) which was machined too deep removing material from surface needed for proper O-ring seal. The lack of material exposes part of the sealing O-ring which could diminish the O-ring sealing capability. With O-ring sealing capability diminished, Valcor cannot ensure that valves with Cover Machining Installed on Solenoid Assembly will perform its safety function during all postulated events.
"This item has historically been manufactured by machining a casting. For the lot involved, castings were not available. Authorization was given to manufacture the Cover directly from suitable bar stock. To accomplish this, Valcor's vendor used the casting drawing and casting machining drawing to manufacture the finished machined part. The combination of these two drawings had insufficient control on the corner radius, resulting in this nonconformance.
"All defective covers in stock have been quarantined and a nonconformance report has been generated. Lack of location controlling dimension on the Cover Machining drawing for 0.190 radius was discovered to be the root cause of the defect. Valcor has created and released a new engineering drawing that properly controls the location of 0.190 radius. This action has been completed as of 11/22/2016. Engineering Manager-Nuclear was responsible to this action.
"Valcor is in a process of notifying all affected customers.
12/05/2016 U.S. Nuclear Regulatory Commission Operations Center Event Report Page 2 "Customers:
Ameren, Valve Part Number V526-6000-16 (Stock# 7731643), S/N 9, QTY 1, Location Ameren Missouri - Callaway Bruce Power (BPC), Valve Part Number V526-6000-20 (Cat ID 142129), S/N 28-36, QTY 9, Bruce NGS "Note: All 9 valves supplied to BPC have been returned to Valcor for nameplate correction and are accounted for.
"If you have any questions or addition information is needed regarding this matter, please contact Fran Lucano at 973-467-8400."
