The failure of the steam dusp and bypass sentrol system during the Generator Trip Test caused a rapid cooldown and depressurination of the reactor coolant 50-3),7, /75-12). This failure re-3 system.
(Referense IE I Inspection Report sulted in several acceptance criteria not being satisfied.
The licensee's acceptance criteria for the Generator Trip Test was as follows:
i Main feedwater valves are ramped t; ut within 20 seconds.
1.
4 2.
Main control board trend recorders monitor their plant parameters on scale.
j 3.
Steam generator pressure is maintained below 1000 psia.
4.
Reactor coolant system pressure is maintained below 2500 psia.
i 5.
Steam dump and bypass control systems returned the plant to the hot shutdown condition.
6.
Evaluation of the response recordings does not indicate the existance of design deficiencies or potential hazards to plant equipment or i
safety.
]
The Generator Trip Test met acceptance criteria 3 and 4.
R Review of the 100% power level plateau test data indicated the licensee is accepting the results of the Generator Trip Test by compensating for the failed acceptance criteria. This was done by reviewing the data collected i
during an unscheduled trip on May 12, 1975, from 93% power caused by loss of a main feed pump, and applying the Generator Trip. Test acceptance criterin to the trip. By combining the two trips all acceptance criteria for the Generator Trip Test has been satisfied.
IE:I has no difficulty in accepting this approach.
