MANUAL REACTOR SCRAM WITH ROD MOTION WHILE SHUTDOWN
"During planned testing of the Control Rod Drive (CRD) system, the reactor trip breakers were opened via the manual reactor trip push buttons to de-energize a CRD motor in response to a high temperature. The partially withdrawn control rods fully inserted and all other rods remained in their initial positions.
"This manual Reactor Protection System (RPS) actuation while the reactor was not critical is reportable in accordance with 10 CFR 50.72(b)(3)(iv)(A)."
The licensee notified the NRC Resident Inspector, the State of Ohio, and Ottawa and Lucas Counties.

AGREEMENT STATE REPORT - FIXED GAUGE STUCK SHUTTER
The following information was received from the Commonwealth of Virginia:
"The licensee discovered a shutter stuck in the open position during a routine test of a fixed gauge on May 5, 2014. The gauge is a Ronan Engineering Model SA1, serial number M-7299. It is used as a low-level indicator in a pre-dryer vessel and contains a 26.9 milliCurie (decay corrected) cesium-137 source. The licensee indicated that using unusual force to try to close the shutter would likely damage the actuator rod mechanism. The shutter is kept in the open position during operations and does not pose an additional radiation exposure to personnel. The licensee performs radiation surveys at one foot from the gauge surface during routine tests. The maximum reported result for this gauge was 300 microR per hour. The licensee has contacted the manufacturer to repair the gauge. The Agency [Virginia Radioactive Materials Program] will continue to monitor the situation until the shutter is repaired."
