20545 H. B. ROBINSON STEMI ELECTRIC PLANT LICENSE DPR-23 FAILURE OF SAMPLE HEAT EXCHANGER
Dear Dr. Morris:
In accordance with Technical Specifications Paragraph 6.6.1.c, the following abnormal occurrence is reported.
On November 24, 1971, an alarm was received on Radiation Monitoring System Channel R-17, Component Cooling System. The primary sample heat exchangers were isolated and the activity level stabilized.
The leak was determined to be in the pressurizer liquid space sample heat exchanger.
Theothersampleheatexpangerswerereturnedtoservice.
Pressurizer liquid space samples will be obtained utilizing another sample heat exchanger pending repair or replacement of this heat exchanger.
A sanple taken on the Component Cooling System following iso-lation of the sample heat exchangers indicated an activity of 8.2 x 10-5 uc/ml. There was no activity released to the environment as thel omponent Cooling System is a closed system.
Yours very truly, NBB:dds cc:
