By letter dated November 30, 1989, the Niagara Mohawk Power Corporation provided for review its procedure for establishing a water seal for,the containment spray system discharge line isolation valves for Nine Mile Point Unit 1.

The NRC staff had requested the above procedure for review in a safety-evaluation report dated May 6, 1988 related to an exemption request for Type C testing of these valves.
