AGREEMENT STATE REPORT - CABLE ON BERTHOLD LB 300 MODEL FAILED
The following report was received from the Texas Department of State Health Services via facsimile:
"On June 7, 2016, the Agency [Texas Department of State Health Services] was notified by the Licensee's consultant that on June 6, 2016, the licensee found the cable on a Berthold LB 300 model gauge that connects the operating rod to a 500 milliCurie cobalt 60 source had failed. The source is currently inserted in the in source well in the normal operating position and cannot be removed. The failure does not create any additional exposure risk to the licensee's workers or members of the general public. The licensee stated there is no access to the vessel the source is located in during operation. The licensee intends to work with the manufacturer to repair the gauge during its next outage. Additional information on this event will be provided in accordance with SA-300."
Texas Incident Report No.: I-9410

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.

MISSING SINGLE TRITIUM EXIT SIGN
The licensee reported the loss of a single tritium exit sign at Moffett Field, CA. The sign was an SRB Technologies sign with an initial activity of 20 Ci. The serial number is 154848. At this time, the licensee is still investigating the disposition of the sign.
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.
