SUMMARY
OF OPERATING EXPERIENCE DOCKETT NO:
50-344 DATE:
1-2-81 COMPLETED BY:
G. G. Fair 4
TELEPHONE:
503-556-3713 Ext. 234 OPERATION:
The plant operated at full power from the first of the month until the 26th when power was reduced to 40% due to favorable hydro-electric supply conditions for the rest of the month.
The steam generator primsry-to-secondary tube leakage increased from about 45 gallons per day at the start of the month to about 60 gallons per day at the end of the month.
Steam generator D is suspected of contributing 70% of the total with the balance mostly f rom steam generator A.
The reactor coolant system gross gamma activity increased from about 2.8 pCi/ml to about 3.2 pCi/ml on 12-19-80.
It is suspected that one fuel pin developed a breach in its cladding. Further analysis is underway to attempt to identify which fuel region contains the new fuel rod failure.
A turbine runback of about 5% from full power occurred on 12-12-80.
On the grid a north-south tie breaker opened and the turbine generator speed control acted to reduce 60 Fnn: in response to the small load rejection. Full power was reattained within the hour.
A minor fire occurred in vital 480 VAC motor control center B22 breaker when the service water booster pump B was cycled. The breaker cycling combined with dust in the housing and possibly loose switch tabs was the apparent cause.
The breaker was returned to service 5.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> later.
MAJOR SAFETY RELATED MAINTENANCE:
Work continued on improvement modifications to the Plant Security and Fire Protection Systems.
Work continued on modifications to the Control and Auxiliary Building walls to improve seismic integrity.
Work continued on TMI-related modification work.
Work began on 12-1-80 on the construction of the Technical Support Center.
MISCELLANE0"S MAINTENANCE:
A fire protection undergroud main pipe was ruptured during excavation work for the Technical Support Center on 12-10-80 and on 12-12-80.
The break was repaired and the-line moved to lessen the possibility of additional breaks.
The positive displacement charging pump overhaul was completed; the pump operating test indicated that additional work must be done to prevent cylinders from loosing their prime from air passing through the pump.
MISCELLANEOUS MAINTENANCE Cont.
Work was completed on the installation of loop seals on the Primary Water and Refueling Water Storage Tanks overflow lines.
Work was completed on the South Boron Injection Tank re 'rculation pump seals.
Work was completed on the West Emergency Diesel Generator semi-annual preventive maintenance.
The P 250 computer's spare disk was tested and loaded with software the week of December 15, 1980.
LICENSE CHANGES:
Amendment 53: Added clarification to the Technical Specification meaning of the term ' operable'.
Amendment 54: Added Technical Specification restriction in section 3.9.13 to when the containment purge exhaust fan may be operated during irradiated fuel movement during refueling.
Corrected the minimum water level over the irradiated core during refueling in section 3.9.10.
Added requirements for redundancy in decay heat removal system in sections 3.9.8.2, 3.4.1.1, 3.4.1.2, and 3.4.1.3.
MISCELLA"EOUS:
Mount St. Helens exhibited minor volcanic activity during the month. No effects were noted at the Trojan site.
l The Institute of Nuclear Power Operations sent an eleven member review team l
to the Trojan site to examine the Trojan Nuclear Plant organization and i
operations.
A Radiation Emergency Response Plant communication drill took place on December 15, 1980.
