Dear Mr. Case:

Enclosed is the final report describing the qualification test program for the Nine Mile Point Unit 1 electrical connectors.

The electrical connectors satisfactorily passed the simulated loss of coolant accident environment test.

My November 30, 1977 letter indicated that an additional test of the electrical connectors would be performed simulating a loss of coolant environment with radiation effects. This test is scheduled to be completed in March, 1978, and the test report will be submitted by April 1, 1978.

Very truly yours, NIAGARA MOHAWK POWER CORPORATION 7gQ33QQ47 Donald P. Disc Vice President-Engineering
