| Event Text HOT OIL SYSTEM EMERGENCY SHUTDOWN FAILS ANNUAL PREVENTATIVE MAINTENANCE CHECK
"It was reported to EH&S Management that on April 29, 2010, the annual preventative maintenance functional check on the hot oil system emergency shutdown system failed. This function is an Item Relied On For Safety (IROFS) and is identified in the Integrated Safety Analysis (ISA) Summary for the conversion area of the Columbia Fuel Fabrication Facility. This IROFS designation is ADUHOS-407 and this IROFS is a control applied to a fire related sequence. Information pertaining to the accident sequence can be found in the January 2010, ISA Summary 03 page 78. There were no actual fire incidents; there were no hazardous materials or special nuclear materials released.
"Current plant status: This functional test requires the conversion lines and associated hot oil dryer be shut down. The conversion lines which utilize the hot oil system protected by this function were in normal shutdown at the time of the functional check was performed. The Columbia Fuel Fabrication Facility is currently shutdown for performance of the annual inventory and associated maintenance outage.
"This notification is made base on 10 CFR 70 Appendix A (b)(2) 'Loss or degradation of items relied on for safety that results in failure to meet the performance requirements of 10 CFR 70.61.' The performance requirements for this accident sequence require the Overall Likelihood Index (OLI) be a -4, which corresponds to Highly Unlikely. With this control failure the sequence OLI is -3 which corresponds to Unlikely.
"Corrective Actions: The corresponding conversion lines and associated hot oil dryer systems are currently in a normal shutdown mode, and will remain so until appropriated troubleshooting and repairs are conducted and the IROFS is restored to an operable status." |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - LOSS OF RADIUM CHECK SOURCE
The following information is a summary of a report provided by the State of North Carolina via facsimile:
A state inspector performed an inspection on April 20, 2010, and learned that a radiation source (Ra-226, 20 microCuries) used in the facility's liquid scintillation counter, Packard Tri-Carb Model, was lost or missing. The RSO [Radiation Safety Officer] and inspector performed a survey of all the labs with a Ludlum Model 19 and were not able to find the source. In addition, it was found that no paperwork was available indicating proper source tracking, leak testing, or disposal of the source. A violation letter has been mailed to the RSO allowing the licensee thirty days to respond to the violation.
NC Incident No. 10-22.
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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
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 AGREEMENT STATE REPORT - STUCK SHUTTER
The State of Texas provided this information via email:
"On May 3, 2010, the licensee discovered that the shutter of a nuclear gauge mounted on the Ryton Quench Salt Solution Tank was stuck in the 'Open' position. The gauge is an Ohmart-Vega Model SH-F1 serial #6966CN, with a 20 mCi Cesium (Cs)-137 source. Initial efforts were made to free the shutter mechanism with penetrating oil and hand pressure, with no results. The shutter mechanism has been tagged out and the manufacturer has been contacted. The gauge is stuck in the open position which is its normal operating position. The source does not present an increased exposure risk to personnel as there are no identified needs for entry/opening of the vessel which would require lockout of the gauge.
"The licensee is working with the manufacturer to arrange for a field service engineer to evaluate/repair/replace the stuck shutter. This shutter had previously failed in October 2009 (EN45399, I-8675.) Repairs had been made and a protective cover for the gauge was installed at that time."
