1 9-14-79 B. A. Svensson 616 465-5901 AUGUST, 1979 Boron injection tank train 'B'eater grounded out.

The heater was replaced and operability checked satisfactorily.

No.

4 steam generator stop valve test selector valve MMO-240 would not move to position B.

Torque switch was found to be malfunctioning.

Replaced torque switch and valve operated s ati s factorily.

HARV-302, CVCS letdown to the VCT or demineralizers, limit switch failed.

The failed limit switch prevented normal valve operation.

The limit switch actuation arm required replacement.

The correct operation of the valve and indication lights were verified.

The release flow rate meter on the waste disposal system control panel was reading low.

RFI-285 release flow rate meter and transmitter were calibrated and operation verified.

J Point 83 of containment air temperature recorder SG-18 was indica-ting full scale.

The RTD fo'r upper containment quad 3 was found to be open.

Replacing the RTD corrected the problem.

Protection channel I delta T/Taverage would periodically spike upward giving spurious overtemperature and overpower channel trips.

The cold-leg RTD was found to be the. problem.

The spare cold-leg RTD was placed in service.

Ice condenser temperature recorder points 1 through 6 were indica-ting full scale.

The problem was traced to a defective relay card in the instrument room.

Replacing the relay card corrected the problem.

The glycol return valve VCR-21 limit switch was causing a ground on the AB battery.

The switch box was cleaned out and the internals of the limit switch were replaced to correct the ground.

The nuclear emergency

alarm, when tested from Unit.2, did not sound.

A faulty transform r was replaced, and the system tested satisfactorily.
