On August 7, power was reduced to 65% to minimize main steam line high radiation levels while shifting condensate demineralizers. Reactor power returned to 99% on August 8.
On August 9          "B" Diesel Generator was declared inoperable for repairs. Repairs.
were completed on August 10 and the unit was returned to service.
On August 12 power was reduced to 70% While putting "E" Condensate demineralizer on line. RWCU'was removed and isolated in an attempt to identify dyrwell leakage.

r REFUELING INFORMATION
          .        The following, refueling information is included in the Monthly Report as requested in a letter to Mr. G. C. Andognini 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, Dbcket Numb'er 50-293.
: 2. Scheduled date for next Refueling Shutdown:        September,1983    !
        .          3. Scheduled date for restart following refueling: November , 1983-
: 4.                                                            *
: 5. Due to their similarity, requests 4, 5, & 6 ard responded to collectively:
: 6. The fuel,' which had been loaded during the 1981 scheduled refueling outage, is .of the same P8x8R design, as loaded the previous outage con-sisting of 112 P8DRB282 assemblies and 60 P8DRB265 assemblies.
: 7.    (a) There are 580 fuel assemblies in the core.                                '
(b) There are' 936 fuel assemblies'in the speSt fu,el pool.
: 8.    (a)    The station is presently licensed to store 2320 spent fuel assemblies.              -
                -              The actual spent fuel storage capacity is 1770 fuel assemblies at present.                                                ,
(b)  The planned spent fuel storage capacity is 2320 fuel assemblies.
: 9. With present spent fuel in storage, the spent fuel pool now has the capacity to accommodate an additional 834 fuel assemblies.

.. BOSTON EDISON COMPANY g PILGRIM NUCLEAR POWER STATION Summary of Operations for AUGUST, 1982 , l The unit was operating at 100% power until August 3, when the reactor scrammed '

due to main steam line radiation believed.to be caused by air intrusion.

The reactor started up on August 4, generator put on grid, main condenser back-washed and power increased to 86%.

1 OnAugust5,powerwas_reducedto60%tochangecontrolrodpatternandsubsequently incre~ased to _ 100% . ' hPCI was declared inoperable on August 6 to repair leak on gland seal condenser and was returned to service. Reactor power was re-turned to 99% power on August 6.

On August 7, power was reduced to 65% to minimize main steam line high radiation levels while shifting condensate demineralizers. Reactor power returned to 99% on August 8.

On August 9 "B" Diesel Generator was declared inoperable for repairs. Repairs.

were completed on August 10 and the unit was returned to service.

On August 12 power was reduced to 70% While putting "E" Condensate demineralizer on line. RWCU'was removed and isolated in an attempt to identify dyrwell leakage.

The reactor scrammed at_._1400_on August 13 due to main steam line hi flow when

'sta'ging struck inain steam 1ine instrument yack.

On August 14 "B" Diesel made inoperable due to ground at 1330. "B" Diesel declared operable at 2014.

Reactor power was increased to 70% on August 19 per direction of Reactor Engineering. ___ ___

Holding.80% power on August 20 while investigating core flows mismatch (speed versus pump flow problem.) Continued increasing power under Reactor Engineering guidance. Trimmed power 2h hours due to high condenser Delta T. Reactor power returned to 99% on August 22, 1982.

On August 26 power was returned to 100% until August 30. On August 31 main condenser was backwashed, and divers cleaned intake bays.

r REFUELING INFORMATION

. The following, refueling information is included in the Monthly Report as requested in a letter to Mr. G. C. Andognini 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, Dbcket Numb'er 50-293.
2. Scheduled date for next Refueling Shutdown: September,1983  !

. 3. Scheduled date for restart following refueling: November , 1983-

4. *
5. Due to their similarity, requests 4, 5, & 6 ard responded to collectively:
6. The fuel,' which had been loaded during the 1981 scheduled refueling outage, is .of the same P8x8R design, as loaded the previous outage con-sisting of 112 P8DRB282 assemblies and 60 P8DRB265 assemblies.
7. (a) There are 580 fuel assemblies in the core. '

(b) There are' 936 fuel assemblies'in the speSt fu,el pool.

8. (a) The station is presently licensed to store 2320 spent fuel assemblies. -

- The actual spent fuel storage capacity is 1770 fuel assemblies at present. ,

(b) The planned spent fuel storage capacity is 2320 fuel assemblies.

9. With present spent fuel in storage, the spent fuel pool now has the capacity to accommodate an additional 834 fuel assemblies.
