Baxley, ccornia 31513 l)orin;; normal plant operation it was discovered that surveiilance procedure llNP-1-3752, llat tery Individual Cell Surveillance, was not pe r fo rmed on i
the requi red date, dovenhe r 26, 1979, as speci fied by Tech Spec 4.9. A. 3.b.
l tipon discovery, the mi.ssed surveillance was linediately performed and found to be nat is factory on !ovenbe r 2 7, 1979.
The Battery Cell. Surveillance was late due to personnel oversight. Thi, is a re-occurring event that is common to both unit s at Plant. llat ch and therefore tue systeu of notifying the responsible pe rsonnel has been rer sed t o provide a double check nystem of not i fi cation.
The nyut en of notifyinr, personnel is being looked into in depth and f urt her revisions nay be inade to insure that surveill an ce is performed on time.
