Refueling Information Significant Operational Events Average Daily Unit Power Level lo Operating Data Reports 13 Unit Shutdowns and Power Reductions. 16 Plant Maintenance 19 Outage Summary ~ 1 ~ ~ ~ ~ ~ ~ 26
0 erations Summar The following summary describes the significant operational activities during the reporting period. Tn support of this summary, a chronological log of significant events is included in this report.
There were fourteen reportable occurrences reported to the NRC during the month of December.
Unit 1 There were no scrams on the unit during the month.
Unit 2 There were three scrams on the unit during the month. On December 2, the reactor scrammed due to abrupt movement of the turbine control valves apparently caused by EHC pressure control problems. The turbine control valves abruptly opened, then started closing, leading to a high neutron flux scram. The reactor was manually scrammed on December 13 to investigate vibration on the 2A recirculation motor, pump, and associated piping. On December 17, the reactor was manually scrammed for implementation of modifica-tions of certain PCIS valves and the installation of acoustic monitoring instrumentation on the MSRV's.
Unit 3
0 erations Summa (Continued)
Unit 3 Unit startup (BOC-3) following a refuel outage began on December 6.
The unit scrammed once during the month. On December 30, the reactor was manually scrammed to install overhead cables from the cooling tower switch gear to the bus tie boards.
Fati ue Usa e Evaluation The cumulative usage factors for the reactor vessel are as follows:
Location Usa e Factor Unit 1 Unit 2 Unit 3 Shell at water line 0.00421 0. 00317 0.00283 Feedwater nozzle 0.20264 0. 13592 0.10480 Closure studs 0.17644 0.11572 0.08561 Note: This accumulated monthly information satisfies technical specification section 6.6.A.17.b(3) reporting requirements.
Common S stems Approximately 1.13E+06 gallons of waste liquid were discharged containing 2.75E+00 curies of activity.
Refuelin Information Unit 2 Unit 1 is scheduled for its third refueling beginning on or about January 3, 1980, with a restart date of February 19, 1980. This refueling will involve loading additional 8 x 8 R (retrofit) fuel assemblies into the core, replacing presently loaded 7 x 7 fuel, LPCI modifications, installing acoustical monitors on KSRV's, and containment isolation modifications.
There are 764 fuel assemblies in the reactor vessel. The spent fuel storage pool presently contains 322 spent 7 x 7 fuel assemblies, two 8 x 8 R fuel assemblies, and 252 new fuel assemblies. Because of modification work to increase spent fuel pool capacity to 3471 assemblies, present capacity is limited to 720 assemblies. With present capacity, Unit 1 does not have full core discharge capability in the pool.
Unit 2
'I Unit 2 is scheduled for its third refueling beginning on September 1, 1980, with a scheduled restart date of October 7, 1980. Resumption of operation on that date will require a change in technical specifications pertaining to the core thermal limits. Licensing information in support of these changes will be submitted to the NRC before the outage. This refueling involves replacing some more 7 x 7 fuel assemblies with 8 x 8 R (retrofit) assemblies.
There are 764 fuel assemblies in the reactor vessel. At the end of the month, there were 132 discharged cycle 1 fuel assemblies and 268 discharged cycle 2 fuel assemblies in the spent fuel storage pool. The present storage capacity of the spent fuel pool is 1080 assemblies. With present capacity, the 1979 refueling would be the last refueling that could be discharged to the spent fuel pool without exceeding that capacity and maintaining full core discharge capability in the pool.
Refuelin Information (Continued)
Unit 3 Unit 3 resumed power operation December 8, 1979, after its second refuel outage which began August 24, 1979. Unit 3 is scheduled for its third refueling beginning on September 6, 1980, with a scheduled restart date of October ll, 1980. This EOC-3 refueli'ng involves loading additional 8 x 8 R (retrofit) assemblies into the core.
There are 764 fuel assemblies presently in the reactor vessel. There are 144 discharged cycle 2 fuel assemblies and 208 discharged cycle 1 fuel assemblies in the spent fuel storage pool. The present storage capacity of the spent fuel pool is 1528 assemblies. With present capacity, the 1980 refueling would be the last refueling that could be discharged to the spent fuel pool without exceeding that capacity and maintaining full core discharge capability in the pool.

26 OUTAGE
SUMMARY
December 1979 The Unit 3, cycle 2 refuel outage was completed on Saturday, December 8, 1979, marking the completion of a 107 day modification, maintenance, and refuel outage.
Unit 2 was shutdown on December 17 for modifications to the primary con-tainment isolation system and installation of an accoustic monitoring system for the main steam relief valves. During this outage, approximately 80 percent of the repair items on the Unit 2 short outage list were completed as well as the PCES and accou tic monitoring mods. Unit 2 was returned to service on December 23.
Unit 3 was shutdown on December 30 for a modification to install an alternate power supply from the cooling tower transformers to the Unit 3 shutdown bus tie board. This modification should be completed and the unit returned to service by the middle of January.
Preparations have been underway for the upcoming Unit 1, cycle 3 refueling outage and should be completed by January l. Unit 1 is scheduled for a 48 day refueling outage to begin January 3, 1980.
