Fort Calhoun Station Unit No. 1 January 1981 Monthly Operations Report I. OPERATIONS

SUMMARY

Fort Calhoun operated at approximately 75% reactor power during the <

month of January.

Power was reduced during the weekend of January 11 to approximately 55% power to accon:modate condenser tube leak testing.

Power was returned to 75% at the co.npletion of the testing.

One reactor trip occurred on January 30 at 0908. The unit was resynchronized to the grid at 1254 on January 31, 1981.

The Supervisor-Operations participated in an emergency procedures workshop in Windsor, Conn. on January 10 thru 12.

Surveillance tests and operational tests were completed as required.

One new Operations personnel reported for duty in January.

A. PERFORMANCE CHARACERISTICS LER Number Peficiency LER 80-030 During the performance of ST-ESF-6, F.2, Appendix F, Diesel Generator #1 (DG-1) failed to start on its secondary air system. DG-1 was removed from service in accordance with Tech. Spec. 2.7(2)i and the secondary air start motors were repaired. Prior to the incident, DG-1 had successfully started on

  • its primary air start system. In addition,-
DG-2 was started to verify its operability.

LER 80-031 During normal operation, a leak developed in l the veld which connects the demineralized i vater flush line to the discharge manifold of Charging Pump CH-1B. Charging pu=ps CH-1A and CH-lc were operable; therefore, the require-ments of Technical Specification 2.2 were met.

A similar' event is described in LER 78-021.

LER Number Deficiency LER 80-032 on 12-10-80, while operating at approximately ,

75% power, the primary heat tracing circuits associated with the piping located between the Boric Acid Pump (CH-hA) discharge and one of the isolation valves (HCV-268) to the charging pump suction header were found to be inoperable.

During the time of the failure, the secondary heat tracing circuits associated with the afore-mentioned piping were operable. In addition, there were at least two remaining operable flov 1 paths from the concentrated boric acid tanks to l

the reactor coolant system as well as a flow path from the SIRWT to the charging pumps as required by Technical Specification 2.2.

B. CHANGES IN OPERATING METHODS None C. RESULTS OF SURVEILLANCE TESTS AND INSPECTIONS None D. CHANGES, TESTS AND' EXPERIMENTS CARRIED OUT WITHOUT COMMISSION APPROVAL Procedure Description / Safety Analysis Summary SP-ALIGN-1 Time-Motion Study for Auxiliary Feedvater Valves W-171, W-172, W-Thk, W-745 Performance of this special procedure does not constitute an Unreviewed Safety Question as defined in 10CFR50_.59, since it incorporates ST- N-1, F.1, to' insure proper valve alignment according to Technical Specification 3 9 and FSAR Section 9.h.

SP-FAUD-1 Fuel Assembly Uplift Condition Detection - all test results acceptable indicating adequate downward force on the fuel assemblies.

SP-FAUD-1 Fuel Assembly Uplift Condition Detection - down-vard force indications on fuel assemblies is acceptable.

Procedure Descriution/ Safety Analysis Summary SP-FAUD-1 (Continued)

Performance of this special procedure does not constitute an Unreviewed Safety Question as defined in 10CFR50.59, since it only involves taking test data and making calculations.

EEAR-80-lh WD-39A/ completed as designed.

Completion of this procedure did not constitute an Unreviewed Safety Question as defined in 10CFR50.59, since it upgraded existing system components for improved performance and safety.

E. RESULTS OF LEAK RATE TESTS PAL door was tested on 1-28-81. The leakage measured was O scem.

F. CHANGES IN PLANT OPERATING STAFF New Auxiliary Operator (Nuclear) is John Paulsen.

G. TRAINING Training for January, 1981, included approximately 35 hours4.050926e-4 days <br />0.00972 hours <br />5.787037e-5 weeks <br />1.33175e-5 months <br /> per week of prepared lectures for Operations, systems training and Tech. Spec. training for all maintenance personnel. Four Hot License candidates received their Reactor Operator licenses.

Fire brigade training was conducted for the fire brigade members.

H. CHANGES, TESTS AND EXPERIMENTS REQUIRING NUCLEAR REGULATORY C0!CIISSION AUTHORIZATION PURSUANT TO 10CFR50 59 Amendment No. 54 regarding Technical Specifications for NUREG 0578, Category A, Modifications and Procedural changes.
