LOSS OF COMPUTER TRAINS ASSOCIATED WITH ERDADS
"At approximately 0917 [EDT], St. Lucie Units 1 and 2 lost both of the computer trains associated with the Emergency Response Data Acquisition and Display System [ERDADS]. After some troubleshooting, the system was restored to service at 1155 [EDT]. This is reportable in accordance with 10 CFR 50.72(b)(3)(xiii), as a major loss of emergency assessment capability."
The licensee notified the NRC Resident Inspector.

MINOR DIESEL FUEL SPILL INTO THE OCEAN
"On September 14, 2010, at approximately 0815 PDT, a minor diesel fuel spill was discovered at the boat dock in the intake cove at the Diablo Canyon Power Plant. A rainbow sheen was observed on the water around the kelp harvester. Harvester operators immediately began deploying absorbent booms and absorbent pads to contain the sheen. It is estimated that less than 2 ounces of diesel fuel reached the water. Mechanics on scene discovered that a small hose clamp had failed on the diesel fuel return line. Repairs were made and the spill was contained. Absorbent pads were used to clean up the residual diesel fuel on the pontoons of the harvester. Repairs were complete and most of the diesel fuel has been absorbed by pads and booms."
"The licensee notified the NRC Resident Inspector."
The licensee also notified the California State Office of Emergency Services, National Response Center, San Luis Obispo County Environmental Health and the Regional Water Quality Control Board.

AGREEMENT STATE REPORT - MISSING GERMANIUM-68 CHECK SOURCE
The following report was obtained from the State of Maryland via e-mail:
"As follow-up to a telephone discussion [on the] afternoon of Sept. 14, 2010 at 1445, [the RSO sent the State of Maryland] this email as a written notification of a presumed lost sealed source containing radioactive material. The telephone notification and this email serve [as] compliance with Section D.1201a, which requires an immediate report of a theft or loss of a source of radiation.
"The sealed source in question contains Germanium-68, a nuclide of half-life 271 days. This nuclide decays to Gallium-68, which itself then decays (with positron emission) with a half-life of 68 minutes to stable Zinc-68. The annihilation radiation from the positron emission is used for PET scanner quality assurance, as in the case of this source.
"This sealed source originally contained 500 microCi of Ge-68 on March 1, 2000. The contained activity of the lost source has been computed to be 0.03 microCi (59000 dpm) as of the date of this notice. The exposure rate of a 1 microCi point (unsealed) source is 5.4 mR/hr at 1 cm; therefore, the exposure rate estimated for this sealed line source at 0.03 microCi is about 0.1 to 0.2 mR/hr at 1 cm. A description of the physical source is [as follows]. The source was manufactured by IPL (product code HEGL-0109) and is 6 inches in length and 1/8 inches in diameter with steel encapsulation.
"The source had been stored and not used (due to low activity), and was last inventoried (and leak-tested) on July 22, 2010. An investigation is currently underway to determine the disposition of this source, and will be submitted to the MDE RHP [Maryland Department of the Environment, Radiological Health Program] per D.1201b within thirty days of this notice."
The State of Maryland will be conducting a follow-up investigation.
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.
