Event Notification Report for November 06, 2014

TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO DROPPED CONTROL ELEMENT ASSEMBLY

"On November 6, 2014 at 1116 Mountain Standard Time (MST), Control Element Assembly (CEA) 15 dropped fully into the core while all other CEAs remained fully withdrawn. Limiting Condition for Operation (LCO) 3.1.5 Condition A was entered for one CEA misaligned from its group which requires restoration of the CEA within 2 hours. An initial power reduction was performed upon receipt of the deviation in accordance with technical specifications. The CEA could not be aligned within 2 hours and LCO 3.1.5 Condition C was entered at 1316 MST which requires entry into Mode 3 within 6 hours. Power reduction continues as necessary to comply with technical specifications.

"No major equipment was inoperable prior to the event that contributed to the event. No emergency classification was required per the Emergency Plan. No automatic essential safety feature actuations occurred and none were required. The Emergency Diesel Generators did not start and were not required. Safety related buses remain energized. The offsite power grid is stable. Other LCOs were entered as required by technical specifications."

The licensee has notified the NRC Resident Inspector.

* * * UPDATE PROVIDED BY RYAN LANE TO JEFF ROTTON AT 0012 EST ON 11/07/2014 * * *

"Efforts to repair the CEA control system and realign CEA 15 with the other CEAs in its regulating group were unsuccessful. Shutdown of Unit 2 was completed at 1636 [MST] in accordance with normal operating procedures to comply with the shutdown requirements of LCO 3.1.5 Condition C. Unit 2 is currently stable in Mode 3 with the reactor coolant system at normal operating temperature and pressure. All equipment responded as expected with the exception of steam generator # 2 economizer feedwater regulating valve which remained 3 percent open. The economizer feedwater isolation valves to both steam generators were manually closed to isolate the economizer feedwater flow paths. The event did not result in any challenges to fission product barriers and there were no adverse safety consequences as a result of this event.

"The NRC Resident Inspector has been informed of the Unit 2 shutdown."

AGREEMENT STATE REPORT - STOLEN TROXLER MOISTURE/DENSITY GAUGE

The following report was received from the State of Washington via email:

"Associated Earth Sciences reported to the State of Washington, Department of Health, Office of Radiation Protection that a Troxler portable gauge, model 3411, serial number 11272, containing 0.1 Ci Cs-137 and .005 Ci Am/Be, was stolen from the back of a pickup while parked overnight at a gauge user's resident apartment complex in Bothell, Washington. The gauge was last seen at 1900 PST the previous night and discovered missing at 0730 PST on November 7.

"The gauge was located in a locked black plastic tool box secured in the bed of the pickup. The tool box containing the portable gauge was stolen from the bed of the truck. Two cables and locks were reported used to secure each side of the tool box to the bed of the truck. It was unclear how the tool box was removed from the truck bed. The licensee reported no cut lock or cable was left behind. It was also unclear if the tool box lid was locked with the same locks and cables used to secure the tool box to the truck. The licensee was asked to provide a photo of their system used to secure the gauge and tool box to the truck. The gauge transport box inside the tool box was reported locked with a single lock. The handle of the gauge was also reported locked.

"The gauge user was asked why the gauge was not returned to the licensed storage location at the end of the day per the condition in the license. The user reported the job site was close to his house and he wanted to avoid the hour and a half drive to the licensed facility to check out a gauge. The theft was reported to the Bothell Police Department and police report #14-25445 was made.

"A follow-up with the licensee will be conducted to investigate possible citations for not returning the gauge for overnight storage in the licensed storage location and proper security for transporting the gauge in a vehicle."

State of Washington Incident Number: WA-14-045.

* * * UPDATE AT 1358 EDT ON 6/8/2015 FROM STEPHEN MATTHEWS TO MARK ABRAMOVITZ * * *

The following report was received via e-mail:

"As of June 8, 2015, the gauge has not been located. Associated Earth Sciences sent [Washington Office of Radiation Protection] a letter dated June 5, 2015 documenting their corrective actions, which consisted of re-training their portable gauge operators, specifically for transportation security. Since the theft occurred over six months ago we feel there is no way to avoid closing this incident as of today, June 8, 2015."

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
