June 1990 Monthly Operating Report I. OPERATIONS
SUMMARY
Fort Calhoun Station returned to 30% power June 1,-1990, after repairing an electro-hydraulic control (EHC) oil leak on the turbine. After steam generator chemistry limits were met, power was increased beyond the 30% ;
holdpoint. A power level of 98% was reached on June 8, On June 10, power was reduced to 94% in preparation for moderator temperature coefficient (MTC) testing. On June 12, an emergency power reduction was initiated due to a heater drain pump suction relief valve failure. Power reduction commenced and was stopped at 76%. Power was returned to 95% after the pump was' isolated. Upon completion of MTC testing, power was increased to 100%
on June 18. On June 22, the unit was taken off-line far balancing of the main generator to reduce vibration. Auxiliary feedwater pump full flow
' tests were also conducted. The unit was reloaded, taken off-line for additional balancing, and reloaded to 95% power on June -25. Due to questionable die:el generator operability (see discussion below), a unit ,
shutdown was initiated June 26, but stopped at 42% power. On June 27, Fort Calhoun Station regained 100% power operation after the diesel generator operability concern was resolved.
During the month of June, two failures occurred on the emergency diesel generator number one (DG-1) voltage regulator. The first failure occurred on June 15 durina a diesel coolant system performance test. After i approximately three hours of operation on a warm (85'F) day, a voltage regulator alfunction occurred which-caused a sudden increase in generator output current. The operator was forced to trip the generator output a breaker and subsequently shut down DG-1. -Troubleshooting revealed a blown i fuse,and 4 degraded diode bridge rectifier. These components were replaced and the surveillance test was performed on June 20 to verify DG-'l'
-operability. Subsequently on June 25 (again:during an extended engine run :
- on an:85'F day) a similar loss of regulation occurred necessitating an ~i engine' shutdown. - - A degraded germanium transistor in the ~ voltage regulator and a blown fuse were determined to be the immediate cause of the problem.
However,!it was also noted that the -voltage regulator cabinet was quite j warm to the touch. Consultation with the regulator manufacturer (GE) h determined that the cabinet containing the regulator was-improperly-L; . ' designed, in that no ventilatian was- provided for cooling the regulator
- ' componeats. A temporary modification was immediately implemented to remove both the DG-1 and DG-2 regulator panel doors in order to provide the necessary cooling. Further DG. testing was performed during warm weather (S0'F) to verify proper operation. No operational problems occurred during a 6.5 hour5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> test of DG 1 at full load. 0G-1 was declared operable on June 27.

During the month of June 1990, the work performed during the 1990 i Refueling Outage was completed or reviewed in the post maintenance work j review process. Significant maintenance is outlined below: )
The' differential pressure transmitter for the steam driven auxiliary feedwater pump, FW-10, was replaced. This transmitter is used to control-the speed, and therefore discharge pressure, of the pump. In addition,-
the steam chest drain valve for the steam turbine was- replaced. ,
' Capacitors were replaced in instrument inverters "C" and "D". This action
, was required due to inservice / shelf-life age of the capacitors. :
During preventive maintenance activities on high pressure safety injection loop valve HCV-311, low megger readings-were observed on the motor for the ,
operator. It was discovered that a motor lead was broken about two inches from the motor. The lead was repaired. There was no indication that the valve-was' inoperable prior to discovery of the broken wire. It is OPPD's c opinion that this is an isolated case sad occurred during the preventive ,
u maintenance activity.
During performance of _the annual diesel generator overhaul for DG-1, it was discovered that the cylinder number five failed its exhaust valve leakage test. .The measured pressure was 42 PSIG vice a minimum acceptable ;
pressure of 56 PSIG. The powcr pack for cylinder number five was replaced. The diesel vendor was on site for the replacement as this is the first failure of a power pack at Fort Calhoun Station.
The following NRC inspections.took place in June:
IR90-30 Residents' Monthly Inspection (05/15/90 thru 06/14/90)
IR90-32 Residents' Monthly Inspection (from 06/15/90 to present) -

B. RESULTS.0F LEAK RATE TESTS The results of the Reactor Coolant System (RCS) leak rate tests for the month of June 1990, indicate a continuation of the very low RCS leakage trend following the-1990 refueling and maintenance outage. 3 The known leakage to the Reactor Coolant Drain Tank and the Pressurizer Quench Tank varied throughout the month from 0.0.tc 0.035
.gpm. The total leak rate, which is the sum of both the known and unknown leak rates, peaked on June 17, 1990 with 0.264 gpm calculated.
Because reactor power w changed several times during the month, a .
great deal' of Deaerateo adter and Boric Acid was added to the' RCS to l 0 control reactivity. This caused more than the normal number of negative leak rate' indications and compromised the accuracy of those tests performed during reactivity changes. It is expected that reactor power will be held relatively constant throughout the summer months, therefore, more accurate leak rate tests should result.
