erations Summa The following summary describes the significant operational activities during the reporting period. In support of this summary, a chronological log of significant events is included in this report and begins on page 5.

There were 6 Reportable Occurrences reported to the NRC during the month of October.

Unit 2 Significant operational events for unit 1 are tabulated by date and time beginning on page 5.

The unit did not scram during the month of October.

Power was administratively limited throughout the month by 60K "B" recirculation pump speed, with "A" loop out of service, except for testing on October 25 at 70K pump speed.

A summary of maintenance work is shown on pages 18 through 30; Unit 2 Significant operational events for Unit 2 are tabulated by date and time beginning on page 6.

There was one scram during 'the month. On October 10 the reactor scrammed during surveillance testing when piping was accidently bumped; causing a false high water level signal in the scram discharge volume.

A summary of maintenance work is shown on pages 18 through 30.

Unit 3 Significant operational events for Unit 3 are tabulated by date and time beginning on page 8.

The unit was down the entire month for refueling.

A summary of maintenance work is shown on pages 18 through 31.

erations Summa (Continued)

Common S stems Approximately 8.92E-1 gallons of waste liquid were discharged containing approximately 7,p2E-1 curies of activity.

Cooling towers 1, 2 (until October 2) and 6 were operational this month for two lift pump operations. Modifications by the tower vendor were continued on Tower 3 and modifications to Tower 2 began on October 2. None of the towers. had significant operational problems.

erational Data The average daily unit power level for units 1, 2, and 3 is shown on pages 9 through 11.

The operating data reports for all three units are shown on pages 12 through 14.

Unit shutdowns and power reductions for all three units are shown on pages 15 through 17.

Refuel in Information Unit 1 Unit 1 fs scheduled for its second refueling begfnnfng on Nobember 18, 1978, wfth a restart date of December 20, 1978. Resumption of operatfon on that date will requfre a change fn technical speciffcatfons pertaining to the core thermal limits. Licensing informatfon in support of these changes was submitted fn August 1978. This refueling will load additional 8 X SR (retrofit) fuel assemblies into the core, replacing presently loaded 7X7 fuel and will involve installing a new recirculation pump trfp (RPT) system.

There are 764 fuel assemblies fn the core. The spent fuel storage pool presently contafns 168 spent 7X7 fuel assemblies and 156 new 8 X 8R fuel assemblies. The px'esent stox'age capacfty of the spent fuel pool fs 1080 assemblies. Present planning is to incxease that capacfty to 3471 assemblies.

With present capacfty, the refueling later fn 1978 would be the last refueling that could be discharged to the spent fuel stoxage pool without exceeding that capacfty and mafnt~g full core discharge capability fn the pool.

Unit 2 Unit 2 fs schedu1ed for fts second refueling beginning on April 22, 1979, with a restart date of July 1, 1979. Resumption of operatfon on that date will require a change in technical specfficatfons pertaining to the core thermal limits. Present scheduling is to submft licensing information in support of these changes before the xefuelfng. This refueling will involve xeplacing.

some more 7 X 7 fuel assemblies with 8 X 8R (retrofit) assemblies.

There are 764 fuel assemblies fn the core. At the end of October there were 132 discharged cycle 1 7 X 7 fuel assemblies fn the spent fuel storage pool.

There are presently 36 new 8 X 8 fuel assemblfes fn the spent fuel storage pool which were not loaded into the core during thfs cycle. The present storage

Re fuelin Information (Continued)

Unit 2 (continued) capacity of the spent fuel pool is 1080 assemblies. Present planning is to increase that capacity to 3471 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.

Unit 3 Unit 3 began its first refueling on September 8, 1978, with a scheduled restart date of November 20, 1978. 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 was submitted in July, 1978. This refueling involves replacing some of the

~

present 8 X 8 fuel assemblies with 8X8R (retrofit) assemblies, modifying the main steam relief valves to increase simmer margin, and installing a new recirculation pump trip (RPT) system.

There are 143 fuel assemblies presently in the core. There are 829 fuel assemblies in the spent fuel storage pool. All but 208 of these will be reloaded into the- core for cycle 2.. The present licensed storage capacity of the spent fuel pool.'is 1132 assemblies.

31 Outa e Summa Unit 3 Octobex'978 The fuel bundles have been sipped and shuffled in order to permit coze reload. The completion of the GE vibration instrumentation removal and control xod operability checks have put fuel reloading about 18 days behind the original critical path schedule.

All the MSXV's are completely zepaired and installed. The majority of the miscellaneous valves have passed the LLRT either initially or after zepaiz. There are still six valves which are to be repaired and retested. A total of seven contzol rod drives weze changed out after pxoblems were en-cquntered with CRD 38-51 and 34<<23. The scram discharge header modification portions of the EECM piping change were completed. The CRD piping zeroute to the steam tunnel along with the CRD nozzle repaix'nd capping were completed.

The recirculation pump trip (RPT) modification for unit 3 is essenti-ally completed with only post modification testing yet to be done. Other modi-fications which axe still underway aze the off-line zadiation monitor, the diesel dxiven fize pump, and the standby gas treatment changes. The zecirculation pump MG set x'otoz repair has been completed and an inspection is underway to see if there is any damage to the unit 1 rotors.

The L-1 moistuxe removal modification has been completed and now reassembly of the low pzessuxe turbine and reactor feedpump tuxbine are complete except for the system oil flush. The mods on the HPCI and RCIC turbines aze also complete.
