-Serial No. 1022
. January 23, 1984 Director of Nuclear Reactor Regulation Attention:
Mr. John F. Stolz Operating Reactor branch No. 4 Division of Operating Reactors United States Nuclear Regulatory Commission Washington, D.C. 20555
Dear Mr. Stolz:
This letter is to conclude our response to your letter dated February 17, 1983 (Log No. 1218), transmitting Amendment 52 which requested Toledo Edison to verify, by tests, the voltage analysis of the Davis-Besse Nuclear Power Station, Unit 1.
In our letter, dated March 23, 1983 (Serial No. 925), we submitted the schedule and test outline for the tests. By this letter we are providing the conclusion based on the test results.
A comparison of the test data with the analytical results calculated from the actual testing conditionslindicated that all test values are above the analytical values indicating the analysis to be on the conservative side.
Very truly yours, ff m
