o 2 lAfter entry into Mode 4 from Mode 5, the operability of EMF-36's low and hign I g trange detectors were not checked during the required surveillance following ther ITTT1 Iplant's change in status.

This is a violation of Tech. Spec. 3.3.3.9(4a) whicht g tis reportable per TS 6.9.1.13(b). Since the event occurred during the pre-l
