| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - IR-192 BRACHYTHERAPY SEED FOUND AT WASTE TRANSFER STATION
The State provided the following information via email:
"On Tuesday, October 10, 2006, at 7:35 A.M., [DELETED] of Waste Management/ Orange Transfer Station, contacted RHB South about a transfer truck that set off their radiation alarm (208.9 kcpm, 4.6 kcpm bkgd). The transfer station knew the waste had been picked up at Chapman Memorial Hospital, who was then contacted. The readings that were taken by [DELETED] were 5 millirem/hour at 1 ft., 1 millirem/hour at 3ft and 0.01 millirem/hour background. They were instructed not to sort or segregate the waste before RHB staff's arrival. At 11:20 A.M., RHB staff met [DELETED] and [DELETED] of Chapman Memorial Hospital at Waste Management to identify the waste. Prior to RHB staff arrival, [DELETED] had surveyed and searched through the waste and found a seed of Ir-192 and placed it inside a clear plastic box. According to [DELETED], he was wearing gloves at the time and had spent about 15 minutes searching for the seed (approximately within 2 feet of the source) and was in direct contact with the source with the thumb and forefinger for about 15 seconds. He then proceeded to place the seed back into the trash can that it was contained in. RHB staff surveyed and identified the waste as a 1.4 - 2.1 millicurie Ir-192 brachytherapy seed. A DOT Exemption (CA-CA-06-41) was issued to [DELETED] to transport the trash can back to Chapman Memorial Hospital and to make sure that the RSO is able to supervise the removal of the seed from the trash bag. The licensee will be cited for failure to do adequate surveys, for disposing of licensed material in an unauthorized manner, and for not following their established policies and procedures. In addition, the licensee will be evaluating the dose to [DELETED], and providing a full report in that regard."
California event number 101006
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. |

"During a review of two nonconformances documented in the station's corrective action system, an unanalyzed condition which could significantly degrade plant safety was noted. The steam generator level instrumentation was not installed as documented in the UFSAR. Letdown valves and piping inside containment was not installed as described in the UFSAR. An unacceptable scenario is a postulated design basis accident in one of the steam generators and a single failure of the letdown piping in the vicinity of the instrumentation piping of the other steam generator, which could, produce conditions that would mislead the operator as to the condition of the plant during the accident."
This condition was discovered during steam generator replacement when the old steam generators were removed and the instrumentation piping became visible. The replacement piping will be routed in accordance with approved drawings. This piping is not required in the current mode.
The licensee notified the NRC Resident Inspector. | |
