2 of 2 9-15-86 At 1400,'The NRC was notified that both trains of safety injection were inoperable.on 9-4-86 due to closure.of IMO-270 and IMO-275, with one pump out on clearance.

The underlying concern is that 2 of 4 loops required by the FSAR were blocked.

9-17-86 At 1003, The TDAFP was declared inoperable because FMO-211 and FMO-241 were closed after discovering leakage into the feedlines.

(T/S 3. 7.1. 2)

At 1335, The TDAFP was declared operable and FMO-211 and FMO-241 were opened, following determination that the check valves leaking-into the feedlines had been reseated.

4 9-19-86 At 0617, The east Component Cooling Water Pump was declared inoperable due to an oil leak.

(T/S 3.7.3.1)

At 1622,-The East Component Cooling Water Pump was declared operable.

l 9-23-86 At 1755,.The NRC was notified of a possible violation l

of shutdown margin, (T/S 3.1.1.1 and 3.'1.1.2) due to Boron --10 depletion.

The incident remains under investigation.

Plant conditions were determined satisfactory for continued operation.
