DOCKFT No. 50-336 ATTACIMENT 1 MILLSTONE NUCLEAR POWER STATION, UNIT No. 2 LOW TDiPERATURE TESTING QUANTIFICATION OF SECONDARY PLANT LOSSES 1742 032 NOVDiBER,1979 8 00111 o f(:, /

QUANTIFICATION OF SECONDARY PLANT LOSSES During operation of Cycle 3 of Millstone Nuclear Power Station, Unit Ib. 2, tests at reduced reactor coolant inlet temperatures will be performed to quantify secondary plant losses. Northeast Nuclear Energy Company (NNECO) has determined that this test cons:itutes an unreviewed safety question and proposes to amend Facility Operating License No. DPR-65 by administratively restricting certain plant parameters to assure that transients or accidents initiated during the test will be less limiting than the current scfety analyses.

Accordingly, NNEC0 hereby proposes to amend Facility Operating License No. DPR-65 by adding a new paragraph 2.C(6) to read as follows:

(6) Northeast Nuclear Energy Company is authorized to perform a test during operation of Cycle 3 at reduced reactor coolant inlet temperature. The duration of the test shall not exceed twenty four (24) hours. During the conduct of the test, the following operating conditions will be administratively maintained :

a) minimum reactor inlet temperature shall be maintained

> 537"F.

b) maximum linear heat rate shall be maintained

$ 14.2 Kw/ft.

c) the pressurizer level shall be maintained at normal operating levels with the reduced average coolant temperature.
