| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - LOST OR MISSING RADIOACTIVE MATERIAL
The State provided the following information via facsimile:
"On 8/7/06, licensee reports being unable to locate two NRD Model P-2021 In-Line Ionizers (S/N A2EJ536 and S/N A2EJ538) each containing up to 10 millicuries of Polonium-210 (138-day half-life). These stainless steel cylindrical items measure 0.5 inches in diameter and just under 3 inches in length. The items were purchased from NRD LLC of Grand Island, NY, in April 2005 (see Sealed Source Registry No. NY-502-D-107-G). The last known location of the items was in a stock storage area at the licensee's former facility in Woburn, MA. The licensee relocated operations from Woburn to Wilmington, MA, in September 2005.
"The licensee assumes the items were lost, and possibly disposed, during the Woburn facility cleanup and relocation effort. The licensee does not believe the items were stolen.
"In order to prevent recurrence, the licensee implemented a specific device use log and assigned an employee to be responsible for device inventory.
"The licensee's search and investigation is ongoing.
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.
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

"On 8/29/06 at 2225 CDT, Browns Ferry Unit 3 initiated a Manual reactor SCRAM due to EHC (Electro-Hydraulic Control) System Reservoir level lowering due to a EHC system leak. The leak was from #2 Main Turbine Control Valve. All Systems responded as required to the manual SCRAM signal. No ECCS (Emergency Core Cooling Systems) initiations occurred as a result of the manual SCRAM signal. Groups 2 (floor drains, etc.), 3 (Reactor Water Cleanup), 6 (Ventilation), & 8 (TIPs) PCIS isolations occurred at + 2 [inches] as expected as a result of the manual SCRAM with all systems isolating as required. The EHC leak rate lowered to approximately zero upon turbine trip. No indications existed of main steam relief valves (MSRVs) opening. Bypass valves controlled reactor pressure due to EHC system staying in service. Repair of the EHC leak is in progress.
"This event is reportable under 10CFR50.72(b)(2)(iv)(B), 'any event or condition that results in a valid actuation of the Reactor Protection System'; 10CFR50.72(b)(3)(iv)(A), 'Any event that results in an actuation of the specified systems'. This event also requires a 60 day written report in accordance with 10CFR50.73(a)(2)(iv)(A)."
Reactor Power was reduced to 78% before the reactor was manually scrammed and all rods fully inserted. The EHC oil is being cleaned up and the oil does not pose a fire threat. All ECCS and the EDGs are fully operable if needed and the electrical grid is stable.
The NRC Resident Inspector was notified of this event by the licensee. |

A Humboldt moisture density gauge was stolen from a job site in Monroe County. Also stolen were tools and another moisture density gauge (see EN #42815). The gauge was locked in its transportation container, which was chained to the building inside a locked storage shed. The Pennsylvania Police in Swift Water were notified.

"While performing work on the refuel floor, an operator received a hand injury. The first aid team responded and the injured hand was covered. Radiation Protection personnel verified that the individual was free of contamination with the exception of the injured hand that had been covered by the first aid team. The individual was transported to an offsite medical facility for treatment as a potentially contaminated injured man."
The licensee notified the NRC Resident Inspector and will notify the state. | |
