Florida Incident No.: FL07-116
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 material event contains a "Less than Cat 3" level of radioactive material. | Event Text COLORADO AGREEMENT STATE REPORT - LOST CUSTOM SOURCE
The State provided the following information via facsimile:
"This is the initial notification for an incident that was reported to this Department [State of Colorado] on this date. A research licensee reported the loss of a custom source containing approximately 120 microcuries of Am-241. The source, a stainless steel tube approximately 6 inches long and 1 inch in diameter, was manufactured by NRD with model number A001, and was used as an air stream ionization device contained in aerosol and gas-phase measurement instruments. The Am-241 is plated on a foil within the tube. The licensee reported the last known use was in March 2006. However, the licensee moved to a new location in December 2006, and the RSO stated that it is possible the source was lost at that time. The licensee reported that all efforts to locate the source have failed including a search of their former use location. No other details are available at this time."
COLORADO Incident #: I07-12
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 |

| Event Text FIRE IN RADIOACTIVE WASTE STORAGE FACILITY
"6 Aug 2007 there was a small fire at ANAD's [Anniston, AL Army Depot] radioactive storage warehouse building 86. During a security patrol they noticed smoke coming out of building 86 and sent out emergency notifications to Safety, Fire Department and later to HazMat. After the Fire Department arrived they sent out notification to contact the Radiation Safety Office (RSO) and to respond. Fire personnel forced the personnel door open and accessed the fire situation from the exterior of the building. The box pallet was smoldering approximately 10 feet from their door. Fire personnel remained at the door entrance and fought the fire from that location. At no time was any of the fire personnel put in jeopardy to be overly exposed to the radioactive waste which was being stored in the warehouse. The fire was extinguished with the very least amount of water, which reduced the spread of contamination to the unaffected part of the warehouse. The fire chief was in contact with the RSO during this operation until his arrival at approximately 7:40. The damage was two wooden box pallets which contained several tritium sources awaiting waste disposal. At this time [the licensee] is not sure exactly how many sources was involved, [estimate the number to around 100 sources] containing on average 10 Ci of tritium each were involved. Many did burst due to the heat thereby releasing the tritium it contained. Surveys to the fire personnel equipment showed no contamination. Personnel were given a bioassay the following day to insure no uptake of tritium gas. Because a small amount of water was used to extinguish the fire, the spread of tritium contamination to the sealed floor area is minimum. The initial survey levels found are in the 8,000-28,000 dpm range to the floor involving an area of 10'X10'.
"Cause of the fire was the result of some decon media (hydrogen peroxide) which had been sealed in a zip lock bag along with some paper towels. The hydrogen peroxide breaks down to pure oxygen and was sealed within a zip lock bag. Apparently there must have been a small amount of some oily residue also within the bag as part of the clean up process. As the oxygen content within the zip lock bag increased and interacted with the oil residue the bag begin to smolder causing the fire to start.
* * * UPDATE PROVIDED BY JEFFREY HAVENNER TO JEFF ROTTON AT 1644 EDT ON 08/07/07 * * *
"The local RSO performed an inventory of the contents of Bldg 86 this afternoon. He has calculated the total release of tritium to be 788 Ci [from 92 devices].

"Unit 2 RPS actuation / unplanned scram occurred at 1506 eastern time on low reactor water level scram initiation. The unit experienced a partial loss of condensate feedwater due to the trip of 2D 4160 volt station service bus [non-safety related]. The 2C 4160 volt bus remained in service supplying power to one condensate pump and one condensate booster pump. Investigation of the 2D 4kv bus trip is in progress. Also received a Group II isolation signal due to low reactor water level."
The reactor is currently stable with water level at 37 inches. Normal feedwater has been used to makeup water level and decay heat is being discharged to the condenser via turbine bypass valves. All rods fully inserted. No SRVs lifted during the transient. The lowest water level reached was -5 inches. The Unit remained in a normal electrical lineup. There were no significant LCOs in effect at the time of the scram. There was no impact on Unit 1. The licensee notes that I&C activities had been in progress on the 2D 4kv bus about the time that it tripped however there is currently no specific connection between these activities and the bus trip.
The licensee notified the NRC Resident Inspector. | |
