Alert

Due to a lapse in appropriations, the NRC has ceased normal operations. However, excepted and exempted activities necessary to maintain critical health and safety functions—as well as essential progress on designated critical activities, including those specified in Executive Order 14300—will continue, consistent with the OMB-Approved NRC Lapse Plan.

RADIOGRAPHY CAMERA SOURCE UNABLE TO BE RETRACTED

Radiographers were performing an exposure when the guide tube disconnect failed and the guide tube disconnected from the camera. This prevents the source from being fully retracted into the camera. The division manager, trained in source retrieval, was able to get the source into the camera and into its shielded position. No overexposures occurred. The quick disconnect was replaced and tested and the camera was returned to service.

The camera was a SPEC-150 using a 62 Ci Ir-192 source.

AGREEMENT STATE - STOLEN TROXLER NUCLEAR DENSITY GAUGE

The following report was received from the State of Florida Bureau of Radiation Control via email:

"[A] Troxler nuclear density gauge model 3440, device serial number 24596, was checked out from [the licensee's] office on Saturday afternoon, May 28th, to take it for repairs. The locked vehicle containing the gauge was parked in a secured parking garage. The vehicle was stolen at 0708 [EDT] according to surveillance video. The vehicle was discovered missing at approximately 1100 [EDT]. [The] City of Miami Police were called immediately.

"Case #160529-161287 filed by [Miami Police]."

Troxler gauge source: Am-241/Be - 40mCi, Cs-137 - 8mCi (originally).

Florida Incident Number: FL16-069

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.

ISOLABLE LEAKAGE IDENTIFIED FROM SEAL WATER LINE WELD INSIDE RCS PRESSURE BOUNDARY

"Susquehanna Unit 1 commenced a manual shutdown on 06/05/2016 for a maintenance outage. At 2202 hours [EDT] on 06/05/2016, operators began reducing power in accordance with plant procedures. At 0352 hours on 06/06/2016, the Main Turbine was tripped with reactor power at approximately 15%.

"The Mode switch was taken to 'STARTUP/HOT STANDBY' (Mode 2) at 0515 hours on 06/06/2016. Manual insertion of control rods was paused as scheduled for entry into the drywell for inspections. There were no ESF actuations.

"At 0556, the licensee identified leakage from a weld on seal water line piping connected to the 1B reactor recirculation pump seal area. The location is within the reactor recirculation loop isolation valves, therefore is isolable from the reactor vessel. The piping is ASME Class 2 and is reactor coolant pressure boundary. The reactor was in Mode 2 at the time of discovery.

"This event is being reported as a plant shutdown required by technical specifications pursuant to 10CFR50.72(b)(2)(i) and degraded condition pursuant to 10CFR50.72(b)(3)(ii)(A).

"Activities are continuing to achieve cold shutdown."

The licensee informed the Commonwealth of Pennsylvania and the NRC Resident Inspector.
