Dear Mr. Tucker:

We have been reviewing the operation of Dresser safety valves as part of TMI Action II.D.1 (Relief and Safety Valve Testing).

In conjunction with this item, the Electric Power Research Institute (EPRI) conducted tests on certain models of Dresser safety valves. The EPRI data is presently being reviewed on a generic basis by the NRC staff and the staff has also begun a review of plant specific reports based on the generic EPRI data.

Pending final resolution of II.D.1, the staff concluded that justification was necessary for continued operation of PWR's which have Dresser safety valves on the primary system.

The enclosed copy of the staff's safety evaluation provides the required justification.

Sincerely, John F. Stolz, Chief Operating Reactors Branch #4 Division of Licensing
