AGREEMENT STATE REPORT - ILLEGAL TRANSFER OF A DEVICE CONTAINING AMERICIUM-241

The following information was receive from the State of Arizona via e-mail:

"On May 16th, 2013, the Agency [Arizona Radiation Regulatory] received notification from the State of Texas that an illegal transfer of a device containing 30 millicuries of Americium-241 occurred on November 19, 2012. The device is a Thermo Niton XLP818 and the device serial number is 6380. The device was shipped from Longview Scrap & Metal, Inc. in Texas to an individual. The address that was given was to a mailbox company where the device was picked up. The company was not able to look up the reference number, due to it being 6+ months since the shipping date.

"The Agency continues to investigate the location of the device."

AZ First Notice: 13-010

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.

AGREEMENT STATE REPORT - SOURCE DISCONNECT

The following information was received via E-mail:

"On June 16, 2013, the licensee reported to the Agency [Texas Department of State Health Services] they had experienced a source disconnect on June 15, 2013. The radiography team cranked the Iridium-192 source out of the Delta 880 camera for the first shot of the day and then they were unable to retrieve the source back into the camera. The source retrieval was performed by authorized persons. From initial reports, using pocket dosimeters readings, the largest whole body dose received was 195 mrem. Dosimetry badges have been sent for processing. The licensee is investigating the cause of the disconnect and will send the equipment to the manufacturer/service company for evaluation. No member of the general public received any dose from this event. More information will be provided as it becomes available, per SA 300."

LOSS OF 230 KV OFFSITE POWER RESULTS IN THE AUTOMATIC START OF EMERGENCY DIESEL GENERATORS

"At 2120 PDT, Diablo Canyon Power Plant experienced a loss of the offsite 230 kV startup power source due to an offsite transmission system relay actuation, resulting in valid anticipatory starts of Units 1 and 2 three emergency diesel generators on each unit. All diesels successfully started but were not loaded. All systems operated as designed with no problems observed.

"The 230 kV startup power source is the only offsite power system designed to be immediately available following an accident. However, the safety related onsite emergency diesel system would have provided power to mitigate the consequences of an accident while the 230 kV was unavailable.

"Restoration of the 230 kV offsite power system is in progress."

The licensee will notify the NRC Resident Inspector.

PLANNED MAINTENANCE ON THE TECHNICAL SUPPORT CENTER BACKUP GENERATOR

"A condition is being reported per TRM 13.13.1 Emergency Response Facilities Action B.2. The functionality of the Technical Support Center (TSC) has been lost due to planned maintenance activities performed on the backup diesel generator that supplies TSC Support Systems. Alternate facilities are available to provide emergency response functions and actions are proceeding to return the TSC to FUNCTIONAL status with high priority. A 10CFR50.54 (q) evaluation has been performed for this planned maintenance activity. The NRC resident inspector has been notified."

EMERGENCY DIESEL GENERATORS UNAVAILABLE FOR AUTO-START

"At 16:15 PDT on 6/24/13, an operator performing a post-event annunciator alarm review of the event reported in EN #49143 identified that the operators the previous night had momentarily disabled all three Unit 1 emergency diesel generators, prior to restoring them to their automatic standby control alignment. Between 22:01:10 PDT and 22:02:54 PDT, on 6/23/13, less than the required minimum two diesel generators were available to automatically respond to a design basis accident. Due to the event reported in EN #49143, the start-up 230 kV power source was also unavailable at this time.

"At the time of this event the operators were in the procedurally guided process of placing the running diesel generator controls to manual, shutting down the running diesel generators, and returning them to the automatic standby control alignment. In this event the operators placed all the diesel generators in manual and shut them down before returning them to automatic control. During this time the operators would have responded to a plant event by returning the affected diesels to auto, whereupon the normal starting and loading sequence would have resumed in accordance with existing accident analyses.

"At the time of discovery all offsite and onsite power sources were operable."

The licensee notified the NRC Resident Inspector.
