| Event Text POSSIBLE RADIOGRAPHER OVEREXPOSURE
Texas Incident #8646
"On July 17, 2009, the Agency [Texas Department of Health] was notified by the licensee that they had been informed by their dosimetry processor that a radiographer had received an exposure exceeding the annual exposure limit. The licensee stated that the individual's thermoluminescent dosimeter was reading 9,000 millirem for the exposure period of June 9, 2009, through July 10, 2009. The licensee conducted a preliminary interview with the employee and was not able to determine how the exposure could have occurred. The radiographer stated that he had not received any dose rate alarms while performing his duties during the monitoring period. He also stated that his self reading pocket dosimeter had never indicated any unusual readings. The licensee's Radiation Safety Officer stated that the individual's duties during the exposure period were almost exclusively dark room operations grading film. The licensee is continuing to investigate and will provide additional information to the Agency [Texas Department of Health] as it becomes available." |

"On July 22, 2009, the Safety Parameter Display System (SPDS) will be removed from service at approximately 0800 hours for Salem Unit 1 to perform planned maintenance to the system. The maintenance consists of the replacement of the uninterruptable power source (UPS) to improve the reliability of the SPDS. The removal of SPDS will also affect the transmission of Salem Unit 1 data from the emergency response data system (ERDS). Appropriate compensatory measures will be in place while SPDS is out of service. SPDS is scheduled to be out of service for approximately 29 hours."
Unit 2 is unaffected by this maintenance work.
The NRC Resident Inspector has been notified.

The Safety Parameter Display System and the Emergency Response Data System were returned to service at 1830 EDT on 7/22/09.
The licensee has notified the NRC Resident Inspector and the States of Delaware and New Jersey Emergency Management Agencies.

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text LOSS OF A LOCAL POWER RANGE MONITOR DETECTOR CONTAINING SPECIAL NUCLEAR MATERIAL
"During the annual physical inventory of special nuclear material at Grand Gulf Nuclear Station (GGNS), a special nuclear material (SNM) inventory discrepancy was discovered. One unirradiated LPRM (local power range monitor) detector could not be located.
"According to SNM inventory sheets, the LPRM detector should have been stored in a LPRM canister in the SNM storage area of the Auxiliary Building. During the inventory, the LPRM detector could not be located. Based on the inventory results and interviews with personnel knowledgeable of the disposal of the LPRM detector, it is believed the LPRM detector was discarded and was shipped to an authorized disposal facility for burial as radioactive waste. The LPRM detector contained a maximum total quantity of all licensed material in the device of approximately 5.84 microCuries of U-234 and U-235 combined (approximately 80wt% U-234 and 20wt% U-235). This quantity meets the criteria for reporting since quantities are greater than 10 times the quantity specified in Appendix C to 10CFR20.
"This material does not represent a hazard to the public health and safety since it is believed the material has been properly handled and disposed of as radioactive waste. There is no evidence of theft or diversion.
"This notification satisfies the 30-day notification requirement of 10 CFR 20.2201(a)(1)(ii). A subsequent written report will be made in accordance with 10 CFR 20.2201(b)."
The licensee has notified the NRC Resident Inspector.
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 | |
