Operations Summary December 1985 Tbe fc' lowing si-.iry describ s the significant operati)nal. ctivities for th-month 31 retc;Lec. In support of this summary, a ch anological log of significant events is included in this report.
Unit 1 Unit one, cycle three refueling / modification outate ended at 2400c, December 19, 1985. The unit remained in an administrative slutdown due to documentation concerns relating to the environmental quals fications of various electrical equipment (NUREG 0588). Maintenance and <ther modifications remain in progress. The present schedule for synchroni. cation of unit one is February 10, 1986. Actual start-up is dependent upon NRC ret iew of the Sequoyah Start-up Readiness Plan and the resolution of significant emIloyee concerns.
The unit has been off-line 131 days.
Unit 2 The unit remained in the administrative shutdown the entire n > nth due to documentation concerns relating to the environmental qualific ition of various electrical equipment (NUREG 0588). Outage related maintenant a and mcdifications are being performed. The present schedule has the unit prepa red to return to service on February 2,1986. Actual start-up is dependent uIon NRC review of the Sequoyah Startup Readiness Plan and the resolution of significant employee concerns. The unit has been off-line 132 days.
Significant Operational Events Unit 1 Date Time Event 12/1/85 0001C Cycle 3 refueling /modifica. ion outage continued. The reactor wai in mode #5.

Fuel Performance Unit 1 The core average fuel exposure accumulated during December was 0.00 HUD/ff!'U.
Unit 2 The core average fuel exposure accumulated with the total accumulated during December was 0.00 MWD /MTU with the total accumulated core average exposure of 8097.51 MWD /MTU.
Spent Fuel Pit Storate Capabilities The t.otal storage capability in the spent fuel pit (SFP) is 1,'86.
- However, theri are five cell locations which are incapable of storing sient fuel. Four locations (A10, All, A24, A25,) are unavailable due to a. suction strainer conflict and one location (A16) is unavailable due to an instrumentation con-flict. Presently, there are a total of 348 spent fuel bundles stored in the SFP. Thus, the remaining storage capacity is 1,033.
PORVs and Safety Valves Summary No PORVs or safety valves were challenged in December 1985.
Licensee Events and Special Reports The following licensee event report (LER) was reported to the Vuelear Regulatory Commission in December 1985.
I{R DESCRIPTION OF EVENT l-85046 On November 14, 1985, at 1305 CST, with unit 1 in mode 6, a deluge valve,1-FCV-26-231, on high pressure fi re protection (HPFP) inadvertently opened and charged the fire hose stations in unit containment annulus and the area arouns the reactor coolant pumps (RCPs). After investigation, the valse was manually isolated and the Unit Operator (U0),. fter reviewing
.the HPFP drawings, determined that only the ho e stations -
around the RCPs were being isolated. In actuality, the annulus hose stations are supplied by this header also ind therefore, they were isolated. Since the annulus contains equipment that was required operable, a failure to comply with action (a) of Technical Specification LCO 3.7.11.4 occurred in that backup hoses were not run (, quired within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />). This condition remained until'its discovery on November 18. 1985, at approximately 1345 CST, during the performance of a HPFP surveillance on valve positions. At that time, the header and associated hose stations were returned to service.
1-85047-Technical Specification 6.12.2 requires access to high radiation areas be controlled by locks with keys administrative 1y controlled by the shift engineer and/or health physics.
On December 15, 1985, it was discovered that several employees may have had keys to locks for six high or potentially high radiation areas.

~QR DESCRIPTION OF EVENT (cont.)
1-85048 An NRC inspection team on December 6, 1985, identified that the maintenance program guidelines (SQM-2 and SQM-57) were required to be PORC reviewed and failure to do so was a violation of the technical specification 6.8.2.
Special Reports There were no special reports for the month of December 1985.
Offsite Dose Calculation Manual Changes No changes were made to the Sequoyah Offsite Dose Calculation tanual during the month.

INSTRUMENT MAINTENANCE Unit 1 An inadvertant containment vent isolation occurred on 12-/-85.is a result of power loss to radiation monitor 1-RM-90-112A (PRO-1-85-362). The power supply plug was verified to be connected to the correct plug sold. Recorder 1-RR-90-112 indicated that the monitor lost power for approximately ten minutes.
It was believed that the monitor's power supply failed in service.
However, the power supply was removed from service, placed under a load test, and was determined to-be functioning properly. Further investigation revealed that the radiation analyzer (RP-30) connector pins could have momentarily opened the power circuit. The connector pins were cleaned and 1-RM-90-112A was returned to service.
The reactor coolant system narrow range RTD manifolds on loops 2,3, and 4 were found damaged during performance of SMI-0-68-28 to install new RTD's for lualified life replacement. MR's were initiated to allow repair by Mechanical Maintenance. Six of eight RTD's have already been replaced.
The remaining two will be completed after the manifolds are repaired.
Unit _2 During performance of a required soldering modification to 2-PT-68-66, RHR suction valve 2-FCV-74-2 was inadvertantly closed, isolating he suction to the RHR pumps (PRO-2-85-134).
Investigation revealed a de'iciency with SI-484 that caused the isolation. The instruction was revisei under a temporary change to include additional steps for prevention o RHR isolation when working on the loop.
2-PT-68-323 was found out of tolerance during performance of efueling calibration, SI-94.1.
PRO-2-85-133 was initiated, the transa tter was re-calibrated, and the loop was returned to service.
Common Contracted with Westinghouse to perform a re-analysis of Sequ( fah's setpoint methodology report. This was necessary to consider maintenante and test equipment inaccuracies and new equipment installations to. ensure safety.
margins are not compromised. Preliminary calculations from Westinghouse are expected to be submitted and reviewed before startup.
During performance of SI-620, auxiliary air compressor pressure switch 0-PS-32-62 was found out of tolerance. PRO-1-85-359 was initisted and the switch was recalibrated.
Continued support for the environmental qualification program. Received QMDS binders and began verification of essential maintenance requirements.
Coordinated with OE to resolve binder discrepancies and equipment installati'n o
problems.
