"According to 180 NAC 3-026.02 (NRC 10 CFR 30.50) this is the twenty four hour report to the HOO [NRC Headquarters Operations Officer] due to an event in which equipment is disabled or fails to function as designed and is required to regulation or license condition and no redundant equipment was available and operable to perform the required safety function.
"The RSO [Radiation Safety Officer], called to report that on May 6th, [2017] at approximately 0645 [CDT] in the morning, Becton Dickinson had a source rack time-out alarm. The Source Rack down switched failed to indicate the rack reached the down position. Upon initial investigations they determined the source was in the down and shielded position. With the help of their service company, Nordion, they bypassed the door interlock and with survey instruments, they ensured the sources were down in the shielded position. No exposure to personnel occurred. Upon initial visual inspection, it appears there may have been a broken [electrical] cable that caused the alarm. Nordion is expected to be on-site today, Monday, May 8, to fix the problem. Will update when we receive the written report." |

The following information was received from the Commonwealth of Virginia via email:
"On May 8, 2017, the licensee notified the Virginia Office of Radiological Health (ORH) that on April 19, 2017, the shutter mechanism of the fixed gauge device (Thermo EGS Gauging Inc. Model TFC-185, Serial Number QC00323; 1250 millicuries of Krypton-85) was not opened all the way to the end as it should function by design. The gauge is used to scan the thickness of plastic sheeting. The licensee has contacted the gauge manufacturer (Thermo EGC Gauging, Inc.) and found that the cause of the problem was due to failure of the Solenoid Rotary Coil found in the device.
"The licensee's report indicated that Thermo EGS Technician replaced the Solenoid Rotary Coil and fixed the problem. The case is closed.
"There was no public health and safety concern.

The following information was obtained from the Commonwealth of Pennsylvania via fax:
"Event Description: The licensee reported that on May 8, 2017 the indicator light on an AccuRay Model U-3 gauge, serial number 6631901, containing 1 Curie of americium-241 would not change from red (open) to green (closed). The area around the shutter was surveyed and the shutter was determined to be in a closed position. A service provider was contacted and the piston was replaced. All regulatory precautions were taken and no exposures occurred.
"Cause of the Event: Equipment failure.
"Actions: The Department [PA Department of Environmental Protection] will perform a reactive inspection. A service provider has already corrected the problem. More information will be provided upon receipt."

"On May 15, 2017 at 1800 hours EDT, the '2A3' 4.16 KV safety related bus unexpectedly de-energized. The '2A' emergency diesel generator (EDG) system received a valid start signal from the undervoltage condition on the '2A3' bus but did not start as the EDG had been removed from service for maintenance. Loss of the '2A3' 4.16 KV bus resulted in a valid actuation of the undervoltage protection relays. The direct cause of the de-energization was determined to be failed secondary side potential transformer fuses. The 'B' train safety related electrical busses were unaffected by the event.
"The '2A3' 4.16 KV bus was reenergized at 2340.
"This event was determined to be reportable pursuant to 10CFR50.72(b)(3)(iv)(A)."
During the electrical transient, the licensee briefly entered Technical Specification 3.0.3 but plant conditions were restored, all required LCOs were satisfied, and Technical Specification 3.0.3 was exited before the plant was required to downpower.
The licensee notified the NRC Resident Inspector. |

"On May 15, 2017 at 1918 hours [CDT], Unit Two High Pressure Coolant Injection (HPCI) Minimum Flow Valve MO 2-2301-14 failed to open as required by procedure and HPCI was declared inoperable. When the HPCI Turbine was tripped, the Minimum Flow Valve did not open when system flow reduced to the low flow setpoint. This event is being reported as a condition that could have prevented fulfillment of a safety function in accordance with 10CFR50.72(b)(3)(v)(D). The HPCI system is a single train system and the loss of HPCI could impact the plant's ability to mitigate the consequences of an accident. In accordance with Technical Specification 3.5.1 Condition G, the Reactor Core Isolation Cooling (RCIC) system was confirmed operable."
This places the plant in a 14-day LCO action statement.
