I will inform the licensee that he should obtain sufficient design information and acceptance criteria guidar.ce from B&W to enable the evaluation of the proper performance of these valves using the lift forces measured or to provide an alternate testing method which will demonstrate their operability.
2.
Headquarters should be informed of this problem to determine if:
a.
Specific acceptance criteria should be included in the Davis-Besse Technical Specifications for the 18 month testing of these valves.
b.
Similar requirements exist or should be added to other B&W facilities using internals vent valves.
Unless I hear to the contrary, I will inform the licensee of the need for additional information.
Other actions will await your decision to bring this matter to the attention of Headquarters.
