~issed Surveillance of Condenser Temperature CONDITIONS PRIOR TO OCCURRENCE:
Operational Mode 1 Reactor Power 65%
DESCRIPTION OF OCCURRENCE:
Between the hours of 1121 and 1353,*a program was being run on the plant computer to calibrate a control room recorder which will be used to monitor condenser circulating water outlet temperature and condenser delta T. *The computer operator was not aware that the program would disrupt normal condenser. temperature indication in the control room and he did not inform the Shift Supervisor so that local temperature readings could be monito~ed as required 'by Environmental Technical Specification~
2. 1
- 1. a, 2. 1. 1. b, 2. 1. 2 and 2. 1. 3.
DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:
