Contrary to the above, an activity offecting quality was not adequately prescribed by documented procedure tn-that the Excess Flow Check Valve Surveillance procedure, QIS 47-1, did not specify the valving sequence for returning a level transmitter to service.
Consequently, on November 5, 1989, an ESF actuation.was generated while returning the i
1-263-58B reactor vessel level transmitter to service (254/89026-01a).
b.
Contrary to the above, an activity affecting quality was not adequately prescribed by documented procedure in that the out of service procedure-I for preparing the 1A 24/48 volt battery for its discharge test at the conclusion of the IB 24/48 volt battery discharge test did not properly sequence the realignment of the batteries.
