Dear Mr. Keppler:
Operating Licenses DPR-58 and DPR-74 Docket Nos.
50-315 and 50-316 ISO No. 80-032/04K-0 The following report is being submitted as required by the Appendix B Techni-cal Specifications, Section 5.4.2. 1, and describes the cause and corrective action of the incident which was verbally reported to Mr. R.E.
- Masse, NRC Region III Inspector, at 1045 hours0.0121 days <br />0.29 hours <br />0.00173 weeks <br />3.976225e-4 months <br /> on March 14, 1980.
During valving in the Unit 2 Failed Fuel Detector, the sampling line was overpressurized causing the safety valve on the system to relieve.
The reactor coolant water dischaxged from this safety valve, drained to the clean sump tank which vented radioactive gas to the Unit 1 vent stack.
This release was detected by the stack radiogas monitor R-26 with the alarm alerting the operatoxs of a possible leak.
Further investigation identified a leak coming from the Unit 2 Failed Fuel Detector which was immediately isolated.
The Unit 1 vent radiogas monitor returned to background levels after isolating the safety valve.
Gas was released from the vent from 1020 to 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> on March 14, 1980.
A total of 0.871 Ci of Xe-133 was released at a rate of 7.74 X 10-4 Ci/Sec.
This is 1.3 percent, of the Technical Specification Appendix B Instantaneous Release Rate Limit Section 2.4.3.a.l.
Also released
- were, 2.37 X 10-6 Ci of I-131, at a xate of 9.87 X 10-10 Ci/Sec.
which is 0.015 percent of Technical Specification Appendix B Instantaneous Release Rate Limit Section 2.4.3.a.2.
This occurrence had no effect on the health and safety of the public.
