' Monthly Operations Report

'I. OPERATIONS SUIGfARY -

Fort Calhoun remained in a refueling operation condition for the month of_ February. The fuel shuffle was completed during February and no abnornalities were discovered.

Surveillance testing continued during the month including several major refueling tests such as the Energency Safeguards With Loss of Offsite Power test.

Several open maintenance requirements were completed during a combined rav vater / component cooling water / instrument air outage.

Operations support of refueling activities continued as normal.

A. PERFORMANCE CHARACTERISTICS 4

LER Humber Deficiency i

LER-020, Rev. 2 During continuing inspections of accessible piping being performed in accordance with IE Bulletin 79-02, two additional snubbers on the safety injection system piping vere found to be inoperable because of improper installa-tion of the anchor bolts. No significant occurrence took place. The probable consequences i vould have been the inability of the snubbers to perform their design functions during a seismic event.

LER-001 On January 2,1980, while operating- at approxi-mately 98% power, the breaker feeding the con-tainment cooling fan motor (VA-33) tripped.

i This trip was believed to have occurred due to faulty trip units in the breaker feeding VA-33.

As a result of VA-33 being tag 6ed "out", redun-dant containment cooling units were tested for gg y g - -

operability in accordance with Technical Speci-D )D fication 2.h(2) . Subsequently, HCV h033, which am'W U ' #

- upon opening allows ccmponent cooling water to flow through the cooling coil for the containment cooling unit, VA-7D would not open from the control room switch.

LER-002 During power operations at approximately 90% and while performing surveillance test ST-SI/CS-1, the containment sump safety injection recircula-tion valve HCV-383-h failed to close from the control room switch. At the time of the failure,

LA. PERFORMANCE CHARACTERISTICS (Continued) 4 LER Number Deficiency the redundant safety injection recirculation -

valve HCV-383-3 was found to be operable.

M.O..#3669 was written to investigate the problem.

LER-003 While attempting to load the diesel generator, DG-2, during the performance of a special e- 24-hour diesel generr. tor test required in i response to IE Bulletin 79-23, the generator field vent to maximum excitation; therefore,

- the diesel was shutdown to prevent generator i ,

damage. The failure was a result of a refer-

! ence 7ener diode drift in the A-C regulator panel. The diode was replaced and the diesel generator testing was resumed. Subsequently i 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> later into the " resumed" test, a radiator tube leak was discovered. This leak

, was repaired per =aintenance order and the 24-hour diesel test was restarted and satis-

• factorily completed without further incident.

LER-00h A fire barrier inside a empty breaker cubicle was degraded to pull in new cabling. A fire watch was established and a maintenance order

, issued to temporarily fill the fire barrier.

The fire watch was not maintained in a continu-ous manner as required b'/ Technical Specification , 2.19 B. - CHANGES IN OPERATING METHODS
