AGREEMENT STATE REPORT - OPERATING ARM FOR NUCLEAR GAUGE BROKEN

The following was received from the State of Texas via email:

"On February 28, 2014, the Agency [State of Texas] received a reciprocity request from a company from the State of Tennessee to perform emergency repairs on a Berthold model LB 8010 nuclear gauge containing a 20 milliCurie cesium-137 source at a generally licensed facility in Texas. The Agency [State of Texas] contacted the Texas licensee and asked if there had been a shutter problem with the gauge. The licensee stated on February 24, 2014, while they were moving the gauge from one location to another, one of their employees noted the operating arm on the shutter appeared bent. The employee attempted to straighten the operating arm and it broke off the gauge. The gauge was placed in the licensee's storage location. The licensee contacted the manufacturer who repaired the gauge shutter on February 25, 2014. The licensee stated no personnel received any significant exposure from the event. Additional information will be provided as it is received in accordance with SA-300."

UNIT 2 LOSS OF SECONDARY CONTAINMENT DUE TO DISCHARGE DAMPER FAILURE

"On March 8, 2014 at 0325 [EST], Secondary Containment Zone 2 (Unit 2 Reactor Building) differential pressure went to 0.0 inches WG [water gauge] following a routine transfer of Unit 2 Reactor Protection System (RPS) Power supplies. Upon restoration from the RPS power supply transfer, one of the Reactor Building Exhaust Fans tripped due to a malfunction of its discharge damper. Zone 2 HVAC was restored at 0335 by placing the other train of fans in service. Zone I (Unit 1 Reactor Building) and III (Common Refuel Floor Area) ventilation remained in service and stable.

"Zone 2 differential pressure recovered to SR 3.6.4.1.1 requirements of 0.25 inches WG within a few minutes and was verified to be stable. LCO 3.6.4.1 was entered at 0325 and exited at 0354. Tech Spec for Secondary Containment Operability requires a negative pressure of at least 0.25 inches water gauge for all three Reactor Building Ventilation Zones.

"There have been no further perturbations in differential pressure and secondary containment remains operable.

"This event is being reported under 10 CFR 50.72(b)(3)(v)(C) and per the guidance of NUREG 1022 Rev 3 section 3.2.7 as a loss of a safety function. There is no redundant Susquehanna Secondary Containment System."

The licensee notified the NRC Resident Inspector.
