unit remained on line for the remainder of the reporting period.

Safety Relief Valve Challenges

Honth of Scottmber 1989 i Requirement

NUREG-0737 T.A.P. II.K.3.3 l There were no safety relief valve challenges during the month.  !

An SRV challenge is defined as anytime an SRV has received a signal to operate via reactor pressure, auto signal (ADS) or control switch (manual). Ref. BECo t 1tr. #81-01 dated 01/05/81.
