- Denotes attended Exit Meeting B.
Vendors Nuclear Industry Involvement The William Powell Company (WPC) has 15 contracts for ASMr C!::, 1, 2, and 3 valves scheduled for completion by mid year 1982.
They also have 2 con-tracts for ASME, Class 3 valves scheduled for completion between 1983 and 1991.
C.
Follow up of the 10 CFR Part 21 Reported Deficiency 1.
Objectives of this area of the inspection were to verify:
a.
That the valve contracts that specified seismic requirements have been re-evaluated using the latest computer program.
b.
That the corrective action has been evaluated to determine its adequacy and proposed modifications have been submitted to the client for review and approval.
c.
That the repair / rework method (s) and procedures have included the QA participation.
2.
Method of Accomolishment The preceding objectives were accomplished by a review of the status repcrts submitted to the NRC and discussions with cognizant personnel.
3.
Findings a.
No nonconformances or unresolved items were identified.
The inspector obtained the following information:
(1) Mississippi Power and Light Company, Grand Gulf Units 1 and 2 (a)
The customer has accepted the valve modifications and/or auxiliary supports as recommended by WPC.
(b) Unit 1.
The repair / rework has been completed.
The majority of the work was performed at the construction site by the erectors personnel, however, WPC management personnel was in
_ attendance at all times in an' adivsory capacity (c) Unit 2.
The required repair / rework has not been started, because WPC and their custemer car.not agree who is respon-sible for the expense of the corrective actions.
(d) WPC has completed the operability testing of the 14 valves at the new specified g loads.
All valves were accepted at the new loads of 6 g's horizontal and 5 g's i
vertical instead of the original requirements of 3 g's in two directions.
(2)
Fermi Unit 2 ' Detroit Edison Company)
WPC management stated that all seismic calculations have been submitted to Detroit Edison Company for their information.
WPC has not received any response relative to this information.
They may not receive a response because, as the inspector stated in Inspection Report No. 99900057/80-02, that the iJrChase Order IE-86734 equipment specification did not require cal-culations for the valve natural frequency.
(3) Cincinnati Gas & Electric Comoany, Zimmer (CG&E)
For all valves the seismic analysis have been completed and the reports submitted to the customer for their review and acceptance.
Most of the valves did not meet the revised requirements of 100 cps and several valves were below the original specified 33 cps.
The customer has not advised WPC of the disposition of these valves.
b.
10 CFR Part 21 Status Report WPC management stated that an interim report w'il be issued within 30 days to the NRC covering the current activ cies.
c.
Potential 10 CFR Part 21 Deficiency WPC performed a stress analysis of 64 valves for the Grand Gulf and Zimmer facilities using the new 6 g load, requirements.
Thesa calculations identified 2 types of 3 inch valves for the Zimmer site that exceeded the assigned stresses.
WPC stated it is their opinion that the deficiency is the result of the additional loading and not the program, because these valves were in conformance with the stress requirements using the original 2 g loadings.
WPC management scated that CG&E has been contacted by telephone stating the problem and requesting their evaluation of the situation relative to tne issuance of a 10 CFR Part 21 Report.
WPC managema. >tated that a written report coataining all the details will be aubaitted to CG&E with a copy to Sargent & Lundy, b/ May 12, 1981, for their evaluation and disposition.
s WPC management also stated that, they will review the WPC valves supplied to other nuclear sites to determine if a similar situation exists.
D.
