Esport Date:
4 August 1977 4.
Occurrence Date:
12 July 1977 (discovered 27 July 1977) 5.
Identification of Occurrence:
0 The point of discharge temperature exceeded 103 F for a time greater than 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, contrary to Environmental Technical Specification 2.2.1.
6.
Conditions Prior to Occurrence:
Mode 1 power operation.
i 7.
Description of Occurrence:
At 1300 it was reported that as a result of reviewing Environmental Data, it was discovered that the point of discharge temperature exceeded 103 F for a period in.
excess of 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> between 2000 on 12 July and 0100 on 13 July 1977. The maximum recorded temperature of this time period was 103.30F. As the load demand of Units 1 and 2 were decreased, the temperature of the point of discharge returned to acceptable values.
j 8.
Designation of Apparent Cause:
This event was caused by high intake temperature and the high power levels of Units 1, 2, and 3.
