NIAGARA M0 HAWK POWER CORPORATION NINE MILE POINT - UNIT 2 DOCKET NO. 50-410 Interim Report for a Problem Concerning Post Weld Heat Treatment Qualification of Feedwater System Angle Valve:
(55(e)-84-37)
Description of the Problem
.The problem pertains to the Past Weld Heat Treatment qualification of angle valves, Mark Nos. 2FWS*HCV54A and B, in the feedwater system.
These are ASME Class 1 valves.
The certified material test' reports provided by the valve manufacturer, Atwood and Morrill Co. Inc., did not document the temperature of g
the simulated post weld ' heat treatment of the test coupons for-the valve bodies.
In
- addition, the weld material post weld heat treatment qualification was performed for a. shorter duration than the production post weld heat treatment of the valve.
This condition has been documented on Nonconformance and Disposition Report No. ZO96..
L.
The matter is still under investigation and a final report will be ' submitted by January -11,1985 r:
