AGREEMENT STATE REPORT - LEAKING ELECTRON CAPTURE SOURCE

The following information was received from the State of California via email:

"A leak test of a generally licensed 9.78 mCi Nickel-63 Electron Capture Source, Serial Number NH285 28.17, manufactured by QSA Global , Inc., indicated 0.0053 uCi of Nickel-63 contamination. The source was stored in room 20D of the Space Sciences Laboratory at the University of California at Berkeley (UCB). The source was taken out of service and repackaged until the investigation by UCB has been completed. A second wipe of the source was taken and was negative."

OFFSITE NOTIFICATION AND MEDIA BRIEFING DUE TO POTENTIAL DISCOVERY OF OFFSHORE FAULT NEAR PLANT

"As part of the ongoing seismic monitoring program, PG&E [Pacific Gas & Electric] in conjunction with the US Geological Survey (USGS) is studying a pattern of seismic activity in close proximity to the Diablo Canyon Power Plant (DCPP). The discovered pattern of seismic activity suggests a potential offshore fault near DCPP. PG&E and the USGS were previously unaware of this potential fault. Initial evaluation shows that the potential fault is closer to DCPP and much smaller than the Hosgri fault, which is the current bounding seismic feature for DCPP.

"Initial assessment indicates that the ground motion from this potential fault is expected to be bounded by the existing seismic design basis for DCPP. The possible impact of this potential fault, including potential ground deformation is the subject of an ongoing evaluation. Given the available data, PG&E and the USGS estimate that it will take up to a year to determine if a seismic fault exists.

"This issue was discussed with US NRC Region IV and Office of US NRC Nuclear Reactor Regulation on November 21, 2008. PG&E is planning a media briefing."

The licensee has notified the NRC Resident Inspector.

LOST I-131 MEDICAL PHARMACEUTICAL

10 packages of medical pharmaceuticals were shipped on 11/19/2008 from Mallinckrodt in Maryland Heights, MO to destinations in Virginia, Maryland, and Pennsylvania. One package did not arrive at the destination: a Mallinckrodt pharmacy in Folcroft, PA. Three couriers were used to ship the packages: transport from Mallinckrodt to the airport, ship by air, and transport to the pharmacies. All of the couriers have searched for the missing package without success.

Source: I-131, 109 mCi

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 - THYROID SCAN ADMINISTERED TO THE WRONG PATIENT

Nevada Physicians Imaging, the licensee, reported to the Nevada State Department of Health that they inadvertently administered 220 microCi of I-123 to the wrong patient. Patient A (the correct patient) was scheduled to receive a thyroid scan. Patient B (the wrong patient) shared the same name as Patient A and was scheduled to receive treatment at the same time. As a result, Patient B underwent a thyroid scan intended for Patient A. It is unknown what diagnostic procedure Patient B was intended to receive.

The patient has not been notified of the incorrect treatment. The licensee was in the process of notifying the prescribing physician.

The State of Nevada will investigate this incident after receiving the licensee's report.
