Summary of Operations for June, 1983 The unit was operating at.100% power at the start of the month.

~ On June 1, the "B" emergency diesel generator was declared inoperable because I of a loss of speed control. (Ref: LER 83-33/03L-0). A power reduction was made on June 4 to backwash the condensers, returning to full load the same day.

On June 5. the "C" SSW pump was made inoperable to correct vibration problems.

and perform preventive maintenance. On June 6 the A0 5033B nitrogen purge .

j_ valve was made inoperable when it could not pass the required timing sur-1-

veillance test (Ref: LER 83-34/03L-0). The "B" D/G was returned to service the same day.

h On June 10..the RWCU System was removed from service in an attempt to identify the source of increasing drywell leakage. A scheduled feedwater heater maintenance outage and drywell entry was started on June 11. Drywell inspection found a leaking hinge pin cover on a feedwater check valve. The 1400-4A MOV, core spray test valve was found with 3~out of 4 operator mounting cap screws-missing (Ref: LER 83-35/03L-0). Various steam leaks were also repaired in the condenser area. Anodes were changed in the water boxes and a ground was b

repaired on the "B" 125 VDC battery system. Two drywell air flow dampers l were found malfunctioning ; an air flow balance was performed after their repair. A seismic hanger was found with loose bolts on the "A" RHR loop. The ,

bolts were tightened and the reactor made critical on June 14 at 2000 hrs.

and the unit placed on line at 0808 hrs. on June 15. On June 16, while reducing 4 power for a rod pattern change the unit tripped at 0030 hrs, because of erratic EPR control. The "C" S/RV was used for pressure control during this scram.

After adjustment, the reactor was made critical at 1157 hrs, the unit placed on line at 1900 hrs. and 100% power was achieved on June 17. Later the same-day, PNPS Was notified by BECo Engineering Dept. that the "A" spent fuel pool heat exchanger support did not meet the required seismic loading criteria. (Ref:

LER 83-29/01T-0). The "A" & "B" SFP loops were isolated with the "B" loop used only as required until the support was returned to original design on June 25.

i On June 18, power was reduced for a condenser backwash and control rod exercises.

t Control rod 10-31 could not be withdrawn and the symmetric rods were inserted.

The maximum power available with this pattern was approximately 96%. The "C" i SSW pump was returned to service on this day. ,

On June 25, power was reduced for a condenser backwash and returned to full available power the same day.

On June 27, the unit was taken off-line because of increasing drywell leakage.

Drywell entry and investigation found MO 202-4B and 202-5A recirculation valves leaking. 'MSlV "B" stem packing was also found to be leaking. Repairs to the

~

"B" 5th point heater. condenser tube cleaning and seal weld leaks in the drywell were also made during this outage. The unit remained off-line until the end of the month.

NOTES: ,

1. The condensers were backwashed every weekend because of horseshoe crab intrusion.

2. The annual emergency preparedness drill was held on June 29.

SAFETY / RELIEF VALVE CHALLENCES MONTH OF JUNE, 1983 Requirement: T.A.P. II.K.3.3 Date: June 16, 1983 Valve #: 203-3C Reactor Pressure: 980 psi Reason: Manual actuation of the valve to control reactor pressure following a scram which was caused by MSIV initiation.

REFUELING INFORMATION The following refueling information is included in the Monthly leport as requested in an NRC letter to BECo dated January 18, 1978:

For your convenience, the information supplied has been enumerated so that each number corresponds to equivalent notation utilized in the request.

1. The name of this facility is Pilgrim Nuclear Power Station, Docket Number 50-293.

2. Scheduled date for next Refueling Shutdown: January, 1984

3. Scheduled date for restart following refueling: April, 19E4 4.

5. Due to their similarity, requests 4, 5, & 6 are responded to collectively:
