| ENS 48902 | 9 April 2013 11:52:00 | The following information was provided by the State of Kansas via fax: This letter is to inform (the Kansas Department of Health & Environment) that yesterday afternoon (on 4/3/13, the RSO) had attempted to move a source from its drywell into its source holder to prepare for maintenance activities in the vessel. The source seemed to be stuck in the drywell. Because the cable restraining the source does not allow the shutter to close until it completely retracted, the shutter would not close. Later last night, after consulting with VEGA Americas and (the company) on-site engineers, (the RSO) attempted again to remove the source and it was free. The source has been safely stored in its holder. There were no reportable personnel exposures. Because of the position of this source 8 feet inside a large vessel with 5 (inch) steel walls, it is shielded at least as well as inside its holder. The shutter in question is on an Ohmart/VEGA model SHLM-CR3 source holder S/N 19077664, containing 2 Ci of Cs-137 in a model A2102 sealed source S/N 0587CO. The source is located at (the company facility) in EI Dorado, KS . . .. It is approximately 140 feet above the ground. Operations and maintenance personnel were notified of the issue. A wipe sample was collected to check for gross leakage. None was indicated. What (the RSO) believe(s) caused this situation was the combination of two (2) things. The reactor was being cooled with nitrogen over the past few days. It has also been raining and snowing. (The RSO) believe(s) water was drawn into the well during cooling and the nitrogen cooled that area of the reactor enough to freeze the water in the well. Ice was present on the cable as it was pulled out. Because the reactor was sufficiently cooled, the nitrogen purge was reduced, thus allowing the reactor to warm slightly by 8 PM when (the RSO) tried again. (The RSO) feel(s) that this was not, in fact, a shutter issue, but an operational issue which (the RSO) will be cognizant of in the future. (The RSO) will simply make sure the internal temperature of this vessel is above 40 degrees F before attempting to remove the top source. Normally it is over 500 Degrees, so water intrusion is not an issue. Again, the source was always in a safe position. At no time were personnel exposed to any reportable levels of radiation.

| ENS 48692 | 23 January 2013 11:00:00 | The following preliminary information was provided by the State of Kansas via fax: Rollover accident involving transport of radiopharmaceuticals. Initial report received at 06:22 A.M. (CST). Condition of driver unknown. Accident location: 2.5 miles north of US 69 and 47 junction, close to Arma, KS. Preliminary information indicates shipment was Tc-99m. Max contact 0.04 mR/h, no damage to packages. Personnel from St. Francis are on site. Driver was taken to the hospital.

| ENS 46030 | 18 June 2010 17:13:00 | The following information was received from the Kansas Department of Health and Environment via facsimile: On July 27, 2006, Honeywell reported by phone that an internal review showed that a static eliminator device shipped 12/18/03, activity 10 mCi, was missing. As of the report date, the activity of this device would have been 84 microCi (138 day half-life). This would give a gamma exposure of 172 microR/h at 30 cm (11 microR/h at 1 m). A search for the device was done, but the device was not found. The root cause was a loss of accountability in that the device was issued to an entire production team or line versus an individual bench within the production line. Corrective action included issuing of the devices through the Health, Safety, and Environment (HSE) department rather than a tool crib. Also the devices will only be issued to an individual to improve personal accountability. The manufacturer was notified. This event is considered closed. Note: This item was determined during the State of Kansas IMPEP (Integrated Material Performance Evaluation) inspection conducted the week of June 14, 2010, that this event was reportable under 10CFR20.2201(a)(1)(ii) - Reporting within 30 days after the occurrence of any lost, stolen or missing material in excess of 10 times the appendix C quantities. Kansas Item Number: KS060014 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.

| ENS 46028 | 18 June 2010 17:13:00 | The following information was received from the Kansas Department of Health and Environment via facsimile: On 3/29/06, Kansas Department of Transportation (KDOT) reported by phone that a portable gauge got hit by a vehicle near SW US 77/50 last night (3/28/06). The gauge was packed in its shipping container and was ready to load on a truck when the accident happened. The shipping container sustained minor damage. An assessment is being made with details to follow. Follow-up actions will be reviewed in inspection space. On 4/7/06, an inspection was conducted of licensee's facility. No items of non-compliance were found. Licensee continues to calibrate and clean their own devices as per their license conditions. If necessary, gauges are sent to the manufacturer for repair. On 5/5/06, reports and narratives were received from KDOT personnel involved with the gauge incident. Gauge failed Validator assessment and is being recalibrated. No other damage to the gauge itself was reported. Note: This item was determined during the State of Kansas IMPEP (Integrated Material Performance Evaluation) inspection conducted the week of June 14, 2010, that this event was reportable under 10CFR30.50(b)(2)(iii) - The 24 hour report of an event where required equipment is disabled or fails to function as designed when no redundant equipment is available and operable to perform the required safety function.
