| 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 background). 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 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. |

| Event Text MOISTURE DENSITY GAUGE FELL FROM TRANSPORT VEHICLE
A portable Troxler moisture density gauge was properly secured in its case with the case and handle locked in place. However, the case was not properly secured in the back of the transport pickup truck. The gauge fell from the back of the truck in front of the business office and was noticed immediately by a public official. This official then brought the gauge to the company office. The gauge was out of the company's possession for approximately 90 seconds.

"On October 13, 2006, at 1034 hours, a Reactor Shutdown was initiated in response to Technical Specification 3.1.7, Action C.1.
"At 2236 hours on October 12, 2006, it was determined that the Standby Liquid Control tank had a pinhole leak. In accordance with ASME Code requirements for Class 2 pressure boundaries, the SLC tank was declared inoperable, rendering the SLC system inoperable. TS Action 3.1.7, Action B.1, was entered at 2236 hours on October 12, 2006 and TS Action 3.1.7, Action C.1, was entered at 0636 hours on October 13, 2006.
"The SLC tank and system remain available. The pinhole leak does not affect the structural integrity of the tank, and the level, temperature and concentration of the boron solution are being maintained per requirements."
All ECCS and EDGs are operable and available and the electrical grid is stable. The licensee informed the NRC Resident Inspector.
At 1130 CDT, the licensee received a 72 hour extension in getting to Mode 3 (Hot Shutdown). The licensee is currently holding reactor power at 82% in anticipation of bringing the reactor to 100% full power while in parallel performing the necessary repairs to the Standby Liquid Control tank. |

"On October 13, 2006 at 1357 (EST) Unit 2 HPCI system was declared inoperable due to indications of a leaking rupture diaphragm in the turbine steam exhaust line.
"This determination was made when water was discovered in the E41-PSH-N012A and E41-PSH-N012C instrument lines during the performance of 0MST- HPCI23Q (HPCI Turbine Exhaust Diaphragm High Pressure Instrument Channel Calibration).
"TS LCO 3.5.1. 'ECCS - Operating,' Condition D was entered for the HPCI system being declared inoperable. The Reactor Core Isolation Cooling (RCIC) system was verified operable per Required Action D.1. Required Action D.2 of TS LCO 3.5.1 requires the HPCI system to be returned to operable status within 14 days.
"The initial safety significance of this condition is considered to be minimal. The RCIC system and all other required ECCS, are operable at this time.
"HPCI has been isolated and will be placed under clearance to allow the turbine exhaust diaphragm to be inspected and replaced if necessary
" The [NRC] Resident Inspector has been notified." |
