LOSS OF SECONDARY CONTAINMENT FOLLOWING SURVEILLANCE TESTING
"On April 3, 2018 at 0019 [EDT], the Susquehanna control room received indication that a loss of Secondary Containment Zone 3 differential pressure had occurred. Control room operators noted the loss following completion of surveillance testing. The cause is under investigation. Zone 3 differential pressure was restored to greater than 0.25 inches WC [water column] at 0145 [EDT].
"Zone 3 differential pressures being less than 0.25 inches WC constitutes a loss of Secondary Containment based on not meeting requirements of SR [Surveillance Requirement] 3.6.4.1.1.
"This event is being reported under 10 CFR 50.72(b)(3)(v)(C) and per the guidance of NUREG-1022, Revision 3, Section 3.2.7, as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment system."
The NRC Resident Inspector has been notified.

AGREEMENT STATE REPORT - STUCK OPEN SHUTTER
The following is a synopsis of a email from the state of Georgia:
On April 3, 2018, the Georgia Radioactive Material Program was informed that a fixed nuclear gauge on the number 4 Digester had a shutter stuck in the open position (normal operation mode). The shutter was made operable on the same day, that the report was made to the state of Georgia.
The gauge is a Kay Ray 7063-P and serial number 9132. The gauge contains 500 mCi of Cs-137. The gauge is in service with all radiation readings acceptable. There was no risk of exposure to employees or members of the public.
