Event Text

UNPLANNED CONTAMINATION

"During a transfer of uranyl nitrate, solution entered a column overflow. Less than one (1) liter of solution leaked from a fitting on the overflow line and contaminated process equipment primarily in an area inaccessible to personnel. The event is being reported because decontamination could not be completed within 24-hours.

"The area was isolated and personnel access was restricted. Cleanup activities were initiated and decontamination was performed in areas accessible to personnel. Decontamination of remaining areas [are] ongoing."

The licensee notified the NRC Resident Inspector.

AGREEMENT STATE - TEXAS - REPORT OF MISSING GAUGE CONTAINING 2 CURIE CESIUM-137 SOURCE

The following was received from the Texas Department of State Health via e-mail:

"The gauge was discovered missing after Agency attempts to collect fees. Gauge registrant had provided self evaluation reports indicating they possessed the gauge and, after being contacted, admitted it was missing. The company had 2 gauges. The second was returned to Thermo Scientific.

"The missing gauge is reported to contain 1 curie of Cs-137. However, the manufacturer's information indicates it held 2 curies. A site investigation will be performed 12/09/08. The source information follows: Manufacturer: Thermo MeasureTech (Now Thermo Fisher Scientific), Model: 5203, Serial Number: B996, Isotope: Cs-137, Activity: 2 Ci, Source serial number: GK3804."

The State of Texas is reporting this as their equivalent to NRC regulation 20.2201(a)(1)(i); reports of theft or loss of licensed materials > 1000 X App. C value.

A representative of the State of Texas (Robert Free) was contacted and it was determined that the date that the gauge went missing or the circumstances are unknown at this time. The licensee is a dredging company that used the density gauge for underwater dredging activities associated with installing underwater pipelines.

Texas report I-8587

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.

AGREEMENT STATE - FIRE IN MANUFACTURING FACILITY CONTAINING FIXED NUCLEAR GAUGES

"N.C. Radiation Protection Section has confirmed the N.C. Division of Emergency Management and local law enforcement were included in initial notifications and remain engaged in the ongoing event evaluation.

"N.C. Radiation Protection Section was notified on 30 November 08 by an unrecorded source from UNIMIN Corporation that there was a major fire in one of their mineral processing facilities in Spruce Pine, NC. Initial reports from the licensee indicate four industrial nuclear gauges containing Cs-137 sealed sources (3 gauges contain 2 mCi each and the fourth contains 50 mCi) were present in the facility at the time of the fire. The damage to the facility exceeds $200,000 and the facility will be out of operation for over one week, so this incident is a reportable event under NC Code 15A NCAC 11.1646(a)(3) & (4).

"Command of the site was taken by the Bureau of Alcohol, Tobacco and Firearms (for fire investigation). Preliminary radiation surveys of the exterior of the facility indicated radiation levels equivalent to background. An inspector from N.C. Radiation Protection was dispatched to the scene on 4 December 08, but was not allowed access to the interior of the facility or to any records maintained by the RSO of UNIMIN Corporation. The inspector was allowed to examine and survey the exterior of the affected facility; he found the structural damage to be significant and that radiation levels about the perimeter of the affected facility were background. The UNIMIN RSO has been able to visually identify three of the four gauges from a vantage point exterior to the facility. Security at this facility is adequate.

"The investigation will be continued on 12/9 or 12/10 by the inspector from the N.C. Radiation Protection Section."

AUTOMATIC REACTOR TRIP DUE TO A FEEDWATER TRANSIENT

"The 'C' condensate pump tripped due to an electrical problem which caused a feedwater transient. The unit [automatically] tripped on high steam generator level at approximately 2301 CST. The unit is in mode 3 and stable. The reactor trip procedures are in progress at this time."

All control rods fully inserted into the core during the reactor trip. Offsite power is available and powering safety loads. The steam generator atmospheric steam dumps lifted momentarily during the transient and reseated. There is no known primary to secondary leakage. Decay heat is being removed via steam dumps to the condenser with makeup provided by auxiliary feedwater to the steam generator. The standby diesel generators and safety systems are available.

The licensee notified the NRC Resident Inspector.
