VRAIN NUCLEAR CENERATING STATION PUBLIC SERVICE COMPANY OF COLORADO 16805 WELD COUNTY ROAD 191/2 PLATIEVILLE, COLORADO 80651 REPORT No. 50-267/81-025/03-L-0 Preliminary IDENTIFICATION OF OCCURRENCE:
The liquid nitrogen storage tank level decreased to less than 650 gallons.
This constitutes operation in a degraded mode of LCO 4.2.12 and is reportable per Fort St. Vrain Technical Specification AC 7.5.2(b)2.
EVENT DESCRIPTION:
On March 17 at 1500 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br />, with the plant operating at 69% power and 225 We, a local loss of, electrical power to the liquid nitrogen storage tank room resulted in the liquid nitrogen storage cank level decreasing below 650 gal-lons. A minimum level of 600 gallons was reached before electrical power was restored to the room. The liquid nitrogen storage tank level was re-stored to normal by 1615 hours0.0187 days <br />0.449 hours <br />0.00267 weeks <br />6.145075e-4 months <br />.
Operation of the low temperature absorber and dewpoint moisture monitors was maintained throughout the occurrence.
CAUSE DESCRIPTION :
The cause of the occurrence was loss of control power to the fill line iso-lation valve.
In June,1980, in an effort to provide for the high makeup requirements of the liquid nitrogen storage tank, a temporary configuration was devised whereby the fill line isolation valve was converted to a level control valve.
This was accomplished by adding a controller and a current / pneumatic con-verter, powered from a local convenience outlet. A 120V circuit breaker feeding receptacles in the liquid nitrogen storage tank room tripped, causing the converter output to go to minimum and closed the fill valve. The cause for the breaker trip is thought to have been portable equipment overloading the circuit.
REPORTABLE OCCURRENCE 81-025 ISSUE O Page 2 of 3 CORRECTIVE ACTION:
The 120V breaker supplying power to the liquid nitrogen storage tank room was reclosed, enabling makeup to the storage tank to be re-established and level was restored to grsater than 650 gallons.
A bypass valve was installed around the fill valve current / pneumatic con-verter, which when opened, would defeat the cenporary control system and allow opening of the fill valve from the Control Room if electrical power is lost to the liquid nitrogen storage tank room.
Pul,lic Service Company of Colorado Nuclear Projects Department is currently evaluating the liquid nitrogen system. Results 4111 be supplied in a future supplemental report.
