| Event Text SAFETY SYSTEM ACTUATION DUE TO INCIDENTAL UF6 RELEASE
"On 11/15/2007 at 0915 instrument mechanics were performing a cell datum calibration in the C-333 Unit 4 Cell 2 cell panel when a strong odor assumed to be HF was noticed after the stage 1 high side pressure valve was opened. The 1/4" valve is on a manifold which accesses pressure taps in various locations in the cell. When the odor was detected a UF6 leak detection head located in the cell panel ducting also actuated. The mechanic opening the valve, immediately closed the valve when the odor was detected and they immediately left the area. HF samples taken a few minutes later in the area around the cell panel were all negative. Precautionary urine samples have been taken from the individuals involved and analysis are being run on the samples.
"It is believed a small incidental UF6 release occurred when the small high side valve was momentarily opened and actuated the UF6 detection system head which is a Q safety system component. At the time of the incident the cell was in operation in a mode which required the system to be operational. This is being reported based on SAR 6.9 Table 1, J2.
"The NRC Resident Inspector has been notified of this event." |

"At approximately 1100 CST on Friday November 16, 2007, Monticello Nuclear Generating Plant determined that there had been a degradation of the Emergency Preparedness response capabilities when the Emergency Response Data System, Offsite Dose Projection (MIDAS), Safety Data Parameter System, selected telephones, and site computer terminals became inoperable in the Technical Support Center (TSC). The loss of these systems is associated with a partial loss of power to the TSC. As a result of these conditions, the TSC was declared non-functional. Emergency Communications remain available with the Emergency Telecommunication System, and Health Physics Network being operable.
"Monticello has verified operability of the ERO notification system (pagers), and the communication circuit used to notify the state and local counties. The siren system for local counties was unaffected by loss of site systems. Plant page and radio systems remain operable. Adequate communications capabilities are operable at this time to implement the emergency plan.
"The site's Emergency Operations Facility (EOF), which is the back-up facility for the TSC, is fully operational and measures are being implemented to direct TSC personnel to the near site EOF in the event of an actual emergency condition.
"The station has informed Wright and Sherburne counties and the Minnesota State Duty Officer of this condition.
"Troubleshooting efforts are in progress. A return to service time for all systems is to be determined. Monticello has determined that this event is reportable to the NRC as an 8-hour non-emergency report in accordance with 10 CFR 50.72 (b)(3)(xiii)."
The licensee notified the NRC Resident Inspector.

The TSC has been restored to an operable configuration.

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text LOST TROXLER GAUGE MODEL 3430; S/N 33784
On 11/16/07 at 1830, an employee of Craig Testing Laboratory was traveling from a McDonald's restaurant to a Wawa convenience store. When the employee reached the convenience store, he noticed the tailgate of his truck was down, and the Troxler moisture density gauge model 3430; serial number 33784 was missing. The employee notified the company RSO and the Hamilton Township Police Department (Case No. 07-63766). A search of the traveled route near the intersection of route 40 and route 50 was conducted without success. The employee stated that when he was at the restaurant the gauge was present in the back of the pickup truck but not properly secured under lock and key. However, when the employee reached the convenience store (which was about a mile away) the gauge and other items were missing. Those other items included a box of concrete cylinder molds and a concrete pressure meter. The licensee does not believe the items were stolen. The licensee believes the gauge and items fell out of the truck. The activity of the sources are: Am-241 (40 millicuries) and Cs-137 (8 millicuries). The licensee has searched e-Bay and Craig's List and is placing reward ads in the local area and ads in the local newspaper.
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 | |
