Dear Mr. Stello:
Serial No.
PO/FHT:scj Docket Nos. :
License Nos.:
115 50-280 50-281 DPR-32 DPR-37 COOLING WATER DISCHARGE TEMPERATURE CHANGE RATE This letter report is furnished in accordance with the provisions of Surry Power Stati?n Technical Specification 4.14.C.1.
Due to heavy ice accumulation at the condenser cooling water intake structure, a reduced flow of condenser cooling water was experienced during the period 0230 to 0330 on February 18, 1979. As a result, the condenser cooling water outlet temperature increased 4.5°F as measured at the station discharge structure during this period.
This rate of temperature change is in excess of 3°F/hr. as permitted by Technical Specification 4.14.A.3. Unit' No. 1 was at 100% power and Unit No. 2 was at refueling shutdown during the time of the occurrence.
There is an ongoing ice prevention program which, upon completion, should preclude this from being a problem in the future.
A survey was conducted to determine if the temperature change had affected the river environment and no evidence of detrimental effects was found.
