REACTOR COOLANT SYSTEM PRESSURE BOUNDARY LEAKAGE IDENTIFIED
"The following event description is based on information currently available. If through subsequent reviews of this event additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10 CFR 50.73.
"At approximately 0030 [MST] on April 7, 2015, while performing planned routine visual examinations of Unit 3 components, the differential pressure instrumentation nozzle on the suction side of the 2A reactor coolant pump (RCP) was observed to have white deposits that appeared to originate at the nozzle penetration. At this time, no additional indications of leakage have been identified for other inspected reactor coolant pressure boundary nozzles.
"Following insulation removal, the piping was examined by qualified engineering personnel. At 0330 [MST] on April 8, 2015, it was determined, based on isotopic analysis, that the white residue is consistent with reactor coolant system fluid. Technical Specifications Limiting Condition of Operation (LCO) 3.4.14 permits no reactor coolant system pressure boundary leakage and therefore, the discovery of leakage from the nozzle is a degradation of a principal safety barrier. This notification is being made for a degraded condition pursuant to the requirements of 10 CFR 50.72(b)(3)(ii)(A).
"The unit had been shutdown for its 18th refueling outage on 4/3/15 at 0000 [MST]. The NRC Resident Inspectors have been informed of this condition."

AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA SOURCE DISCONNECT
The following information was received from the State of Texas via email:
"On April 8, 2015, the Agency [Texas Department of State Health Services] was notified by the licensee's site radiation safety officer (RSO) of a source disconnect. The RSO stated a radiography crew had contacted him [from a field site in Charco, TX] and informed him that after the first exposure of a 62.2 curie Iridium - 192 source, they could not retract the source back into a QSA 880D exposure device. The RSO stated he arrived at the site and found dose rates at the boundaries to be less than 0.5 millirem per hour. The RSO, who is on the license to retrieve a source, detached the guide tube from the camera and using a pair of tongs, lifted the collimator and the source slid out on the ground. The RSO placed bags of lead over the source. The RSO cranked the drive cable through the camera and connected the drive cable to the source. The RSO then retracted the source into the camera locking it in place. The RSO stated he inspected the camera and crankout device in the field and could not find any cause for the disconnect. The maximum dose during the event was received by the RSO who received 24 millirem to his hand and 16 millirem to his chest.
"No member of the general public was exposed as a result of this event.
"Additional information will be provided as it is received in accordance with SA-300."

LOST BRACHYTHERAPY SEED
The medical center performed a procedure where an I-125 seed (0.3 mCi) was implanted in a breast lumpectomy site. The Brachytherapy Radiation Safety Officer believes that when the lump was removed, the implanted seed was also discarded as bio-waste. The seed dimensions are 4.5 mm long by 0.1 mm in diameter. The biological waste is no longer on site.

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.
