This' report contains the highlights of the Fort St. Vrain, Unit No.1, activities operated under the provisions of the Nuclear Regulatory Commission Operating License DPR-34. This report is for the month of January, 1984.
1.0 NARRATIVE
SUMMARY
OF OPERATING EXPERIENCE AND AAJOR SAFETY RELATED MAINTENANCE The month of January was highlignted by pre-shutdown activities, shutdown, and plant reconfiguration for shutdown activities.
The plant operated near 70% power for the first two weeks, except for six hours when the turbine was tripped due to amplidyne problems. The reactor power was reduced to 50%, due to leakage problems on "1A" circulator inlet piping.
On January 17, the power was reduced to 30% to allow going to the " low power" position. Pre-shutdown surveillances were then completed, and on January 19th, the turbine generator was manually tripped. Core Support Floor testing was then performed while decreasing power. The reactor was manually scrammed on January 20, 1984, but decay heat removal requirements delayed complete cora depressurization until January 26, 1984.
Prior to refueling, the helium purification inlet valves and the
/^ '_ "B" train cooler were removed, and the electrical bus work was
\: started. Essentia'i Gus I has been removed from service, and is being upgraded at this time. Shutdown work included the deaerator and condenser inspection, instrument calibrations, loop 1 valve work, IA circulator piping removal, moisture
. monitor work, and removal of the low pressure rotor on the turbine generator.
All work is progressing, but asbestos insulation removal delays have slowed progress. Refueling is delayed due to electrical cable conductor problems in the Fuel Handling Machine cable network.
