AGREEMENT STATE REPORT- REPORTED STOLEN AND THEN FOUND MOISTURE/DENSITY GAUGE

The following information was received by e-mail:

"On September 8, 2011, Arrow Engineering contacted California Office of Emergency Services to report a stolen moisture/density gauge, Troxler model 3440 Plus, 8 mCi Cs-137 source and 40 mCi Am:Be-214 source, S/N 39529. The gauge was locked in the transport case, secured in the back of a vehicle, a 2001 Chevy Silverado. The gauge operator discovered the vehicle stolen at approximately [0500 PDT], when he was leaving his home, to proceed to the worksite. The operator then notified police and then the Radiation Safety Officer (RSO). The Los Angeles County Sheriffs Department arrived approximately [0545 PDT] and the operator made his report of the stolen vehicle and gauge. After the operator had made the report, he then proceeded to return to work.

"After the RSO was notified of the incident, he proceeded to contact Los Angeles County Radiation Management and left a detailed message and then contacted the Office of Emergency Services to report the incident. Approximately [0940 PDT] a LA Co. inspector notified the ICE RAM South of the incident. An ICE inspector then contacted the RSO to obtain information on the incident. The RSO confirmed the incident took place at the residence of the operator sometime in the early morning of September 8, 2011, prior to [0500 PDT], when the operator discovered that the vehicle was missing. He stated that the operator had left the gauge in the locked transport case, locked in the bed of the pickup with two chains and three locks. He also stated that the operator had an alarm on the vehicle, but did not hear it since he was likely asleep at the time. He also stated that the vehicle was not able to be stored in the garage since it was a 4 wheel drive vehicle. The gauge was left in the vehicle since the operator had returned from a jobsite late the prior evening and had an early appointment the next morning. The RSO was informed to provide a written report within 30 days, to place an ad and a reward in the local newspaper and to notify ICE if the gauge is found.

"At approximately 1100 [PDT], the RSO contacted RHB reporting that the vehicle was found with the gauge and transport case still locked in the bed of the truck and with a broken drivers side window. The RSO stated that the vehicle was left in the driveway of a neighbors house. It was found by the owner while returning home from the office at approximately 1030 [PDT]. The owner then contacted the LA Co. Sheriff and was told not to touch the vehicle before the Sheriff arrived. When they arrived, he was allowed to check the gauge case to confirm that the gauge was still inside and intact. The operator was able to confirm this and the Sheriff were able to inspect the vehicle and gather evidence. The licensee was informed to take a leak test immediately and keep the gauge out of service until the leak test results were returned and confirmed to be below the contamination limit.

"While the investigation is still ongoing, pending licensee's findings in their 30 day report, the licensee is likely to be cited for storing the gauge in an unauthorized storage location, for improperly securing the gauge, or leaving the gauge unattended."

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.

MISSING/UNACCOUNTED FOR AM-241 SPECIAL FORM SEALED SOURCE IN A M43A1 CHEMICAL AGENT DETECTOR

A Michigan National Guard Unit in Lansing, MI while preparing for deployment identified that a 250 microcurie Am-241 special form sealed source (S/N Z03-C-36663) was missing from a M43A1 Chemical Agent Detector. The detector was last confirmed intact in 2008 prior to the Unit's last deployment to Iraq.

The licensee has initiated a formal investigation and notified the State of Michigan of the incident.

* * * UPDATE AT 1332 EDT ON 09/13/11 FROM THOMAS GIZICKI TO S. SANDIN VIA FAX * * *

"Description of the event: On September 12, 2011 the Michigan Army National Guard, United States Property and Fiscal Office (USPFO) warehouse, Lansing, MI reported to the licensee of a missing Am-241 cell from a M43A1 chemical agent detector. The Am-241 cell is a sealed source, special form that contains 250 microcuries of Am-241. The Am-241 cell (s/n C-36663) belonged to detector s/n D-36025. Detector is NSN 6665-01-081-8140 and SSDR no. NR-1129-D-102-S (inactive).

"The detector with Am-241 cell belongs to 'A' Co. 125th Infantry. A physical inventory was performed by 'A' Co. in January 2008 at which time the unit was deployed to Kuwait for 1 year. The unit was getting ready for redeployment to Kuwait in the next several weeks and performed an inspection of all equipment needing to be shipped. It was at this time that cell C-36663 was discovered missing from the detector. The USPFO warehouse was searched wall to wall and the missing cell was not found. The Michigan National Guard is conducting a formal investigation regarding the lost radioactive cell. Exposure to personnel is not likely to occur in an unrestricted area since the Am-241 source is contained in a cell module that is sealed source special form."

Notified R3DO (Lipa) and FSME (McIntosh). Provided to ILTAB (Whitney) via e-mail.

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.

For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf

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.

CONTROL ROOM ENVELOPE DECLARED INOPERABLE

"On September 12, 2011, at 1745 PDT operators declared the control room envelope (CRE) inoperable and entered Technical Specification (TS) 3.7.10 Action B. This was due to discovery of inadequately documented CRE inleakage test data.

"On September 12, 2011, DCPP [Diablo Canyon Power Plant] personnel reviewing the CRE testing dated February 3, 2005 determined that the test report provided inadequate information to conclude that the most limiting alignment for control room pressurization would result in zero cubic feet per minute (CFM) inleakage into the CRE, contrary to the Final Safety Analysis Report (FSAR) accident analysis for the most limiting design basis accident. Three of the four ventilation alignments tested had reported values of inleakage greater than zero CFM.

"Plant staff implemented compensatory measures by placing the control room ventilation system into its pressurization accident alignment at 1828 PDT using the alignment from the test which had a reported value of zero CFM inleakage. Additionally, administrative controls are being established to maintain post-Loss of Coolant Accident Emergency Core Cooling System leakage at a rate that would ensure operator doses are maintained less than the FSAR accident analysis results for the highest inleakage rate reported by the test.

"Plant personnel notified the NRC Resident Inspector."

LOSS OF TECHNICAL SUPPORT CENTER VENTILATION

"VA-106, TSC HVAC Unit VA-107 Rooftop Condensing Unit, tripped off and attempts to restart were unsuccessful. The cause of VA-106 tripping is unknown at this time. Troubleshooting is in progress.

"This condition renders the Technical Support Center unavailable for Emergency Planning Responses. Approved compensatory actions are to relocate personnel to alternate facilities if required. This condition is being reported pursuant to 10 CFR 50.72(b)(3)(xiii) for Loss of Emergency Preparedness Capabilities."

The licensee informed the NRC Resident Inspector.
