| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text LOST TRITIUM EXIT SIGNS
"Pursuant to Federal Regulation 10 CFR 31.5(a), Dominion Transmission, Inc. is a general licensee of the NRC because it possesses and uses byproduct material in the form of tritium exit signs (TES). Consistent with Federal requirements, Dominion is providing the subject report regarding two (2) lost TES.
"Dominion has established a company-wide program to inventory TES. Inventory efforts have identified that the following TES which were present at the previous inventory cannot be located and are presumed lost:
"Serial Number: CO563528
Model Number: BX
Activity: 20 Curies
"Serial Number: CO563530
Model Number: BX
Activity: 20 Curies
"Dominion conducted this most recent inventory during a recent construction re-modeling project involving the building of a new addition at its Lightburn Station. Dominion has no information that these TES have been transferred. Accordingly, and in addition to physical searches for the TES conducted by Dominion, Dominion interviewed key on-site personnel, contractors and vendors who had worked on the site. Interviewed personnel include the Dominion project manager, site safety personnel and the lead contractor who performed the demolition. None of these interviewees recall disposing of the TES.
"Dominion also contacted the local trash removal services (C and D Dumpster) and they have confirmed that a dumpster was removed from the site during the remodeling project. Dominion therefore contacted S and S Landfill. S and S Landfill has no equipment available to monitor for radiation levels and consequently could not provide us with any relevant information as to the possible disposition of these TES.
"As a result of these investigative efforts, Dominion concluded that these TES are lost. We have also confirmed that all other TES are currently in place at the Lightburn Station facility."
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.

| Event Text AGREEMENT STATE REPORT - DAMAGED FIXED NUCLEAR GAUGE
The following report was received from the State of Tennessee via email:
"On February 16, 2016 the RSO [Radiation Safety Officer] of Jarden Zinc reported that one of their fixed nuclear gauges (make, model, serial number not reported) had been damaged. Details concerning the cause of the damage were unknown. Surveys of the damaged gauge indicate that the gauge shutter is in the closed position, no radiation beam is emanating from the gauge, and there do not appear to be any exposures to staff. The gauge has been moved into storage until the manufacturer can arrive to inspect the gauge. The RSO indicated that follow-up information to the Tennessee Division of Radiological Health would occur within 24 hours."

| This material event contains a "Category 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - IRIDIUM 192 SOURCE LOST DURING SHIPMENT
The following was received from Florida via email:
"On 2 June 2015, an Ir-192 source was shipped via common carrier from Sand Lake Cancer Center in Orlando, Florida to Alpha-Omega Services [AOS] in Vinton, Louisiana. The common carrier states on the travel history that the source was unable to be shipped and was returning to the shipper. There is no date or time for the actual return, and no signature on file (as required). A representative from Elekta reported the 4.7Ci Ir-192 source missing on 17 February 2016 after receiving the information from Sand Lake. Sand Lake and AOS have been in contact between themselves and the common carrier and were unable to locate the source. [The Elekta representative] has already reported this incident to Georgia and is currently trying to get in touch with the common carrier RSO."
Florida incident #: FL16-032
* * * UPDATE PROVIDED BY KELLIE ANDERSON TO JEFF ROTTON AT 1136 EST ON 02/19/2016 * * *
The following information was provided via email:
Alpha-Omega Services reported to the State of Florida that the source has been located and it is in the Alpha-Omega Services offices in Vinton, LA where the source was being shipped to originally. I seems that it was an administrative error that caused the source to be reported as missing. The State of Florida considers incident # FL16-032 to be closed.
Notified the R1DO (Dentel), R4DO (Vasquez), and NMSS Events Notification Group via email.
THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL
Category 3 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging.

"At 1100 CST on February 24, 2016, with the plant in cold shutdown (Mode 4), the shift manager was notified of a condition that could potentially prevent the automatic closure of the circuit breakers powering the emergency ventilation fans in the both the Division 1 and 2 emergency diesel generator rooms. These fans are not in Technical Specifications, however, they provide a support function to the emergency diesel generators, requiring that both diesel generators to be declared inoperable. This inoperability constitutes a condition that could potentially prevent fulfillment of the safety function of onsite AC power sources, and is being reported pursuant to 10 CFR 50.72(b)(3)(v).
"Four additional breakers are affected by the same condition. These breakers supply power to Division 1 and 2 containment unit coolers and the Division 1 and 2 auxiliary building 141 ft. elevation general area unit coolers. The auxiliary building unit coolers are not in Technical Specifications, however, they provide a support function to the electrical distribution system. The Technical Specification required action is to declare both trains of the residual heat removal system (shutdown cooling mode) inoperable. This inoperability constitutes a condition that could potentially prevent the fulfillment of the decay heat removal safety function, and is being reported pursuant to 10 CFR 50.72(b)(3)(v).
"Division 2 residual heat removal is operating in shutdown cooling, satisfactorily maintaining reactor coolant temperature. The affected breakers can be manually operated to start/stop their associated equipment, if necessary for operation."
This condition was identified during an Engineering review. The licensee has compensatory measures in place. Long term corrective actions are under review.
The licensee informed the NRC Resident Inspector. | |
