.Nonroutine Environmental Operating Report No. 50-219 83-3-1 Report Date February.14, 1983 Occurrence Date January 23, 1983~
Identification of Occurrence Exceeding a limiting condition as defined in the Environmental Technical Specifications, paragraph 2.1.4.3 -- less than two dilution pumps were operating for greater than 15 minutes, and ambient. water temperature was less than 60*F.
This event is considered to be a Nonroutine Environmental Report as defined in the Technical Specifications, Appendix "B", ' Paragraph 5.6.2.
Conditions Prior to Occurrence Dilution. Pump Flow 5.20 E5 GPM Circulating Water Pump Flow 3.45 E5 GPM Prior to the occurrence, the ambient water. temperature in the intake canal was 32.3*F. The condenser discharge water temperature was 49.8'F, and the-U.S.
Route 9 Discharge bridge temperature was 36.2*F.
Description of Occurrence At 1044 hours0.0121 days <br />0.29 hours <br />0.00173 weeks <br />3.97242e-4 months <br /> on 23 January, dilution pumps 1-2 and 1-3 tripped off leaving no.
dilution pumps in service.
Apparent Cause of Occurrence A power cable failure to the main breaker of the dilution pumps caused the shutdown of dilution pumps 1-2 and 1-3. Specifically, electrical terminations
.(stress cones) failed in the system.
