This report contains the highlignts of the Fort St. Vrain, Unit No. 1, activities operated under the provisions of the Nuclear Regulatory Commission Operating License CPR-34. This report is for the month of August, 1982. | |||
1.0 NARRATIVE | |||
==SUMMARY== | |||
OF OPERATING EXPERIENCE AND MAJOR SAFETY RELATED MAINTENANCE 1.1 Summary Reactor power continued throughout the month at about 70% | |||
and 215 MWe, with the exception of three brief reductions to 30% caused by malfunctioning control equipment, and one turbine generator trip caused by a grounded instrument line. | |||
Work is in progress to replace #5 feedwater heater. | |||
1.2 Operations The reactor continues operation at 70% power with electrical generation at 215 MW. One reduction in power to 55%, 175 MWe, was made on request by the System Load Dispatcher for five hours. | |||
Repairs to several snubbers were made with no reduction of g | |||
power operation. | |||
Brushes were replaced on the turbine generator amplidyne unit. | |||
A faulty reheat temperature sensing element caused a brief l reduction of power on August 13. | |||
l On August 17, a faulty relay in the main steam pressure l controller caused a turbine runback and a rod runback of the reactor. The plant was brought back to 70% power manually, and the relay was repaired. | |||
On August 27, 10 helium circulator tripped due to a faulty speed signal to the circulator speed controller. Power was reduced to 30%, the malfunction was corrected, and 70% | |||
power operation resumed. The same evening, the turbine generator was tripped while repairing a master trip indicating light receptacle. The turbine generator was | |||
; placed on line, and 70% power attained at approximately | |||
! 0700 hours the following morning. | |||
A Change Notice was completed on August 30, for all helium circulator speed control systems, which selects the higher a speed signal from either of two channels. This will lessen | |||
-z-the chance of a circulator trip from faulty speed indication as had occurred on August 27, 1982. | |||
A drain line from the cold reheat flash tank to the deaerator ruptured and was isolated for repair. | |||
Lightening struck the 60 meter weather tower. Recorders at the tower were restored upon replacing a damaged power supply. | |||

1.0 NARRATIVE
SUMMARY
OF OPERATING EXPERIENCE AND MAJOR SAFETY RELATED MAINTENANCE 1.1 Summary Reactor power continued throughout the month at about 70%
and 215 MWe, with the exception of three brief reductions to 30% caused by malfunctioning control equipment, and one turbine generator trip caused by a grounded instrument line.
Work is in progress to replace #5 feedwater heater.
1.2 Operations The reactor continues operation at 70% power with electrical generation at 215 MW. One reduction in power to 55%, 175 MWe, was made on request by the System Load Dispatcher for five hours.
Repairs to several snubbers were made with no reduction of g
power operation.
Brushes were replaced on the turbine generator amplidyne unit.
A faulty reheat temperature sensing element caused a brief l reduction of power on August 13.
l On August 17, a faulty relay in the main steam pressure l controller caused a turbine runback and a rod runback of the reactor. The plant was brought back to 70% power manually, and the relay was repaired.
On August 27, 10 helium circulator tripped due to a faulty speed signal to the circulator speed controller. Power was reduced to 30%, the malfunction was corrected, and 70%
power operation resumed. The same evening, the turbine generator was tripped while repairing a master trip indicating light receptacle. The turbine generator was

A Change Notice was completed on August 30, for all helium circulator speed control systems, which selects the higher a speed signal from either of two channels. This will lessen
-z-the chance of a circulator trip from faulty speed indication as had occurred on August 27, 1982.
A drain line from the cold reheat flash tank to the deaerator ruptured and was isolated for repair.
Lightening struck the 60 meter weather tower. Recorders at the tower were restored upon replacing a damaged power supply.

- The 1992 estimated date is based on the understanding that spent fuel discharged during the tern of the Agreements will be stored by DOE at the Idaho Chemical Processing Plant. The storage capacity has evidently been sized to accomodate eight fuel segments. It is estimated that the eighth fuel-segment will be discharged in 1992.
