AGREEMENT STATE REPORT INVOLVING A STOLEN NUCLEAR GAUGE

"At 0830 on November 28, 2005, RHB-Brea received a call from the licensee that one of their gauges (CPN, MC1-DRP, #MD20306488 containing 10 mCi Cs-137 and 50 mCi Am-241:Be) was stolen out of their construction trailer that was located at a temporary job site (KB Homes - "The Cove" construction site, located at the corner of Warren Road and Cottonwood in San Jacinto, CA). Three of the four construction trailers at this job site had been broken into over the same time period - the security metal plates (covering the locks to the doors) had all been pried open and the locks to the doors were cut off and were removed from the site. The theft occurred sometime between 1130 on November 23, 2005 (when the gauge user secured the gauge inside the construction trailer) and 0722 on November 28, 2005 (when the gauge user returned to the job site and discovered the theft). The last leak test for this gauge was performed on January 4, 2005 and was negative for removable contamination. The licensee contacted the San Jacinto Police Department to report the theft. They will also post a $1000 reward for the gauge in the local paper."

"CA NMED #: XCA-824"

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.

INVERTER INOPERABLE FOR GREATER THAN ALLOWED TIME PER TECHNICAL SPECIFICATIONS

"This report is being made pursuant to the requirements of License Condition 2.G of the Seabrook Station Operating License. Inverter 1F was inoperable for greater than the 24 hours allowed by Technical Specification 3.8.3.1.h. The inverter was inoperable for a total of 35 hours 59 minutes. The inverter was declared to be inoperable at 0323 on November 29, 2005 and was not returned to operable status until 1522 on November 30, 2005, this exceeded the 24 hour TS limit. The NRC approved a Notice of Enforcement Discretion at 0220 on November 30, 2005, which allowed an extension of 18 hours (until 2123 11/30/05). The inverter was declared operable prior to the expiration of the extension. This event will be documented in a License Event Report pursuant to the requirements of 10CFR50.73."

CONTROL ROOM EMERGENCY VENTILATION AC SYSTEM INOPERABLE

"On November 30, 2005, at 1500 hours, the Control Room Emergency Ventilation Air Conditioning (CREV AC) system was declared inoperable due to failure of the associated air conditioning compressor. As a result, Technical Specification 3.7.5 Condition A was entered.

"The CREV AC system maintains a habitable control room environment and ensures the operability of components in the control room emergency zone during accident conditions.

"This notification is being made in accordance with 10 CFR 50.72(b)(3)(v)(D) because the CREV system is a single train system, and loss of the CREV AC could impact the plant's ability to mitigate the consequences of an accident."

The licensee informed the NRC Resident Inspector.
