The following was received from the State of Tennessee via email:
"A fire occurred in an off gas dust collector and particulate filtration system used for ventilation from a process providing oxidation of metal depleted uranium chips. Alarm engaged and fire suppression system engaged. The local fire department responded and reinforced suppression. The fire department departed by 11:20 AM. Initial indications indicate no releases to the environment based on visual indications and stack monitoring systems not alarming. Negative pressure to the building was maintained. Smears taken outside of the building and radiologically controlled area does not indicate any elevated activity outside of the building. Air samples are being pulled and analyzed for workplace and air effluent stacks. Bioassays were being conducted to assess worker and firemen. A follow-up report will be submitted upon receipt of further information."

The following was received from the State of North Dakota via email:
"Taney Engineering, Inc. (Taney) reported the loss of a moisture/density gauge (Troxler Model No. 3430, Serial No. 30530) that contained a 1.48GBq (40mCi) Am-241:Be source (Serial No. 47-27626) and a 0.3 GBq (8 mCi) Cs-137 source (Serial No. 77-13400) currently licensed under North Dakota Department of Health License No. 33-53306-01. This event was initially reported to the Minot, North Dakota Police Department at 11:54 P.M. on Sunday, 11/15/2015. At that time, the field inspector noticed the Troxler nuclear density gauge designated above to be missing from the bed of his truck at the end of the day. The field inspector stated the nuclear density gauge was in the yellow transport box secured in the bed of his truck with chains and locks to both side handles and locks on the transport case when he stopped at Wal-Mart located at 3900 S Broadway St., Minot, ND 58701. When he returned from the store, the equipment was still secure in the bed of his truck. He drove to Buffalo Wild Wings in the adjoining parking lot located at 3820 S Broadway St., Minot, ND 58701 at approximately 11:35 P.M. He placed an order for take-out and waited for food inside. He arrived home in Minot, ND 58701 before 11:50 P.M. to drop off groceries before checking in the nuclear gauge and discovered company equipment, including the gauge, missing from the back of his truck. He immediately notified the Minot Police Department, filed incident report No. 2015-00036173. He then notified Troxler Electronic Laboratories at 877-876-9537. He than notified Taney."
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.

The following was received from the Commonwealth of Virginia via email:
"On October 27th, the VRMP [Virginia Radioactive Materials Program] received a letter from CJCLDS [The Church of Jesus Christ of Latter Day Saints] stating that 25 exit signs each containing approximately 3 curies of H-3 were lost. The letter stated that a contractor was hired in July to replace the H-3 signs with new electric signs and place the H-3 signs in a closet so that CJCLDS staff could properly dispose of them by packaging and returning them. The letter stated the signs were not in the designated location.
"The contractor was contacted by the VRMP who stated that an electrical sub-contractor was hired to perform this work. That company was contacted and VRMP was able to speak to the electrician and his supervisor. The electrician stated verbally and in writing that he removed the H-3 exit signs and placed them in the designated location.
"A search was performed by CJCLDS staff and church members were contacted to see if they had seen the signs. It has been concluded that the signs were discarded by accident and can't be found or recovered at this time.
"This location and the serial numbers of the H-3 signs could not be found in our GL database. The NRC was contacted to search their GL database for the serial numbers to no avail."

"At 2148 EST on November 23, 2015, Salem Unit 2 declared an Unusual Event due to reactor coolant system leakage greater than 10 gallons per minute. While performing troubleshooting to determine the source of leakage from the Emergency Core Cooling System high head safety injection piping, a motor operated valve was opened and the high head piping relief valve lifted. Indications in the control room calculated the leak rate at 16 gallons per minute based on the change in Pressurizer level. The leak was terminated when the motor operated valve was closed and the relief valve reseated. The time [duration] of the leak was about one minute."
The licensee notified the NRC Resident Inspector.
Notified DHS SWO, FEMA Ops Center, and NICC Watch Officer. E-mailed FEMA NWC and Nuclear SSA.

The licensee terminated the Unusual Event at 0100 EST on 11/24/15. The licensee will be cooling down and depressurizing to mode 5 in order to replace the affected valve.
The licensee will be notifying the NRC Resident Inspector as well as the New Jersey State police, Delaware State Police and local emergency dispatch.
Notified the R1DO (Dwyer), NRR EO (Morris), IRD MOC (Stapleton), DHS SWO, FEMA Ops enter, and NICC Watch Officer. E-mailed FEMA NWC and Nuclear SSA.

"This event is being reported in accordance with 10 CFR 50.72(b)(3)(v)(D). 'Any event of condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident,' due to inoperability of both trains of the Emergency Core Cooling System high head safety injection systems.
"The unusual event was exited at 0100 [EST] on November 24th, 2015, when the Emergency Core Cooling System high head safety injection piping inlet valves were closed, ensuring isolation of the relief valve. The criteria for exit was leakage rate was below the 10 GPM rate. The plant is in mode 3 cooling down to mode 5.
"The licensee notified the states of New Jersey and Delaware, Lower Alloways Township, and the NRC Resident Inspector."

"On 11/24/2015 at 0534 hours [CST] the plant was in MODE 3 [hot standby] for a forced outage. While initially placing Shutdown Cooling (SDC) in service, the 12 Residual Heat Removal (RHR) pump tripped approximately 8-10 seconds after start due to the closure of the RHR SDC suction isolation valves. This was determined to be from an invalid signal on the Reactor Pressure Vessel (RPV) suction interlock. This is being reported under 10 CFR 50.72 (b)(3)(v)(B) as an event or condition that could have prevented the fulfillment of the safety function of structures or systems that are needed to remove residual heat. This event did not challenge the ability to maintain safe shutdown conditions, remove residual heat, control the release of radioactive material, or mitigate the consequences of an accident as other methods of decay heat removal were being utilized successfully to establish plant conditions.
"The NRC Resident Inspector has been notified."
This incident places the RHR system in a 24-hour technical specification limiting condition for operations. |
