TECH SPEC REQUIRED SHUTDOWN DUE TO SWING BUS AUTOMATIC THROWOVER FAILURE
"While performing a Technical Specification surveillance functional test of the [Low Pressure Coolant Injection] LPCI swing bus automatic throwover scheme, the throwover function failed, rendering LPCI Loop Select inoperable. Time of [the] event was 1521 [EDT]. Inoperable LPCI Loop Select results in entry into Tech Spec 3.0.3. Power reduction activities were briefed and power reduction commenced at 1615. Maintenance is currently implementing a contingency work order to correct the auto throwover failure.
"This report is made pursuant to 10 CFR 50.72(b)(2)(i), initiation of plant shutdown required by the plant's Technical Specifications; and 10 CFR 50.72(b)(3)(v)(D), an event or condition that could have prevented the fulfillment of the safety function of systems needed to mitigate the consequences of an accident."
Offsite and Emergency power remain available.
The NRC Resident Inspector was notified.

"On March 9, 2015, at approximately 1521 [EDT], while performing a functional test of the LPCI swing bus automatic throwover scheme, the throwover function failed, rendering LPCI Loop Select inoperable. Tech Spec 3.0.3 was entered and power reduction commenced at 1615 [EDT]. Power was lowered to approximately 80%. Maintenance led a troubleshooting process that found and corrected the equipment problem. At approximately 2311 [EDT], the limiting condition for operating was cleared and LPCI Loop Select was declared operable. Tech Spec 3.0.3 was exited at that time."
The licensee notified the NRC Resident Inspector. The plant has returned to 100% power.

TEMPORARY LOSS OF POWER TO AIR MONITORING PUMPS
"The air monitoring vacuum pumps were disabled for approximately 20 minutes. Due to an unplanned power outage, the soft water supply to the air monitoring vacuum pump seals on the 2nd floor of the Feed Materials Building (FMB) was lost. These pumps provide vacuum for the stack monitoring and personnel area monitoring systems in the FMB. The secondary and tertiary water supplies to the pumps were not available when needed. This caused the vacuum pumps to be shut down until a temporary water supply could be established. A temporary water supply was reestablished to the pump seals. The pumps were restored to service at approximately 1520 CDT on 03/09/2015."
The licensee has contacted NRC Region II inspector David Hartland regarding this event.

AGREEMENT STATE REPORT - RADIOACTIVE MATERIAL GAUGE SOURCE NOT FULLY RETRACTED
The following report was received from the Tennessee Department of Environment and Conservation Division of Radiological Health via email:
"The licensee called to report a radioactive material gauge with stuck source in the closed position. The gauge is a Vega Model SHLM-C2, with three 37 millicurie Cs-137 rod sources, SNs 2609, 2611, and 2612. Radiation measurements indicated the source was in the shielded position. On March 9, 2015, a Vega service representative visited the site and inspected the gauge. It was discovered the source was not completely retracted. The gauge remains bolted to the process vessel, and is scheduled for replacement after additional retraction or equivalent means to secure the source has been implemented. No additional radiation exposure to personnel occurred. Current radiation levels are the same as found under normal conditions when the source is in the retracted position."
