. . Operational Summarv for January 1989 I The unit remained in cold shutdown until January 2, 1989 when the reactor was made critical at 1705 hours0.0197 days 0.474 hours 0.00282 weeks 6.487525e-4 months . Training criticals were performed until 1132 hours0.0131 days 0.314 hours 0.00187 weeks 4.30726e-4 months on January 4, 1989. Training criticals were required because 16 l operators have provisional NRC licenses which require reactivity manipulations a before unrestricted licenses can be issued. Following completion of training criticals, a plant heatup was commenced. By January 7, 1989 the reactor was steady at approximately 140 psig. High Pressure Coolant Injection and Reactor i Core Isolation Cooling testing was r"ccessfully completed by January 10, i 1989. At approximately 2100 hours0.0243 days 0.583 hours 0.00347 weeks 7.9905e-4 months to January 10, 1989 a controlled shutdown was initiated due to questions which arose concerning NRC Generic Letter 88-14 and the operability status of the torus to reactor building vacuum breakers.

Plant Design Change 89-04 was implemented to provide a safety related, independent air supply for the secondary containment to torus vacuum breaker isolation valves. Following a successful test of the air supply, the reactor was made critical on January 27 at 1412 hours0.0163 days 0.392 hours 0.00233 weeks 5.37266e-4 months . At 2110 hours0.0244 days 0.586 hours 0.00349 weeks 8.02855e-4 months , due to an.

excessive leak rate on the vacuum breaker isolation valves accumulators, a controlled shutdown was initiated, and an Unusual Event notification was made per technical specification requirements. The Unusual Event was terminated at 2215 hours0.0256 days 0.615 hours 0.00366 weeks 8.428075e-4 months . The unit remained in cold shutdown through the end of the month to facilitate repairs.

Safety Relief Valve Challenges Month of January 1989 Requirement: NUREG-0737 T.A.P. II.K.3.3 There were no safety relief valve challenges during the month.

: kFFUELING INFORMATION

.The following refueling information is included in the Monthly Report as L requested in an NRC letter to BECo, dated January 18, 1978: 1 L j 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 1991

3. Scheduled date for restart following refueling: March 1991

4. Due to their similarity, requests 4, 5, & 6 are responded to collectively-under #6.

5. See #6.

6. The new fuel ' loaded'during the 1986/87 refueling outage was of the same design as loaded in the previous outage, and consisted of 192 assemblies.

7. (a) There are 580 fuel assemblies in the core.

(b) .There are 1320 fuel assemblies in the spent fuel pool.

8. (a) The station is presently licensed to store 2320 spent fuel assemblies. The actual usable spent fuel storage capacity is 2320 fuel assemblies.

(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 1000 fuel assemblies.
