SUMMARY
Fort Calhoun Station operated at a nominal 100% power throughout the month of December 1991.
On December 1, 1991, the Process Radiation Monitrrs for the Radioactive Waste Processing Building (RM-041,-042, & 043) were found to have zero sample flow due to a closed exhaust damper in the building ventilation system. This required entry-into Technical Specification LC0 2.9.1 (2) which requires - grab samples each 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for gaseous activity and continuous sampling for particulate and iodine activity on the Rad Waste Building exhaust stack. The damper apparently failed closed due to the loss -tf the control air in the building. The control air system self-contained air compressor had tripped off and not restarted following a momentary . loss of off-site (161kV) power. The air compressor was restarted and sample flow was re-established to the monitors shortly after discovery. This allowed clearing the LCO.
On-December 4, 1991, a four-hour notification was made to the NRC due to a failure to adequately test the equalizing valve on the containment inner Personnel Air Lock (PAL) door. The e tested per Technical Specification 3.5(qualizing volve had not been leak 3) s measure the inner door was declared inoperable and the outer PAL door was immediately danger tagged closed to prevent a breach of Containment integrity.- ~ Preparations for testing the equalizing valve included fabricating a test assembly and obtaining a waiver of compliance from the NRC to allow the outer PAL door to be opened. On December 6, 1991 the NRC granted Omaha Public Power District (OPPD) a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> waiver to allow testing of the inner PAL door equalizing valve. The valve was ,
~
successfully tested.on December 7, 1991.
On. December 10,1991, the last shipment of new Westinghouse fuel was received and inspected for the upcoming refueling outage. Currently all new fuel assemblies have been accepted by OPPD exccpt for one (R-001).
The assembly in question has a small surface defect on one fuel pin.
On December 16, 1991 a one-hour notification was made to the NRC based on discovery.thatportIonsofthetubingusedtotesttheContainmentPAL were not seismically qualified; thus, the PAL was outside the design bas?
of the plant. The non-qualified test equipment has been removed and new seismically rated tubing and isolation valves will be-installed January
-1992.
Unknown leakage from the RCS had been increasing over the last few months.
During the month of December, efforts to identify the leak path found that the source of leakage was the High Pressure Safety Injection (HPSI) -
Charging system crosstie valve HCV-2988. To prevent any further leakage-from this path, the Charging - HPSI manual isolation valve (CH-li,1) was closed. This resulted in a reduction in RCS unknown leakage to normal values.

LIC-92-007R Page 2 On December 19, 1991, the 161kV Offsite power feed to the plant was taken out of service to repair a power pole arm which had been damaged by a winter storm earlier in the year. Repairs were completed by OPPD's Electric Operations Division and power was restored in approximately six hours.
The following hRC inspections took place during December 1991:
IER No. 91-24 Routine Resident Inspection IER No. 91-26 Special Inspection (Containment Integrity)
The following LERs were submitted during December 1991:
jJR NO. Descrintion 91-24 ESF Actuation after Pulling Fuses 91-25 S1 Pipe Supports Outside Design Basis 91-26 SR0 without NRC Physical 91-27 RCDT Sampling (WD-1060) 91-28 Unmonitored Release on Loss of 161kV A. SAFETY VALVES OR PORV CHALLENGES OR FAILURES WHICH OCCURRED NONE B. RESULTS OF LEAK RATE TESTS Total RCS leak rate increased from 0.475 gpm at the first of the month to 0.712 gpm on December 18, when the major source of leakage was identified. Charging flow was leaking through HCV-2988 to the 2500 psig HPSI header and then through the "B" Safety Injection Tank leakage cooler to the Reactor Coolant Drain Tank. HCV-2988 is the cross connect valve between the charging header and the high pressure HPSI header. The valve is a solenoid operated valve that is normally open to provide a flow path for hot leg injection and long term core cool ing. The valve is scheduled to be rsplaced during the 1992 refueling outage.
HCV-2988 was isolated by closing CH-191. This reduced the leakage to .137 gpm. With CH-191 closed, the total RCS leakage remained near this amount the rest of the month.
