AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA SOURCE DISCONNECT

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

"On June 27, 2018, the Agency [Texas Department of State Health Services] was notified by the licensee's corporate radiation safety officer (CRSO) that one of his radiography crew had experienced a source disconnect. The crew was using a QSA 880D exposure device containing a 113.1 Curie iridium - 192 source. After completing the first shot on a new location on the pipeline, the crew could not get the source to return to the exposure device. The crew contacted the CRSO and set up new barriers at 2 millirem. The CRSO and a second individual qualified for source retrieval arrived at the site at 1743 hours. The retrieval team (RT) surveyed the guide tube and determined the source was in the collimator. The RT removed the guide tube from the exposure device and removed the camera from the area. Using a set of long tongs, the guide tube was removed from the pipe and the source slid down the guide tube until the connector was exposed. They could see the drive cable had broken near the connector. The source was shielded with bags of lead shot. The CRSO disconnected the broken drive cable from the source pigtail and connected the pigtail to a new drive cable that had been installed on the camera. The source was retracted to the shielded position in the camera. The camera and crank out device and drive cable will be sent to the manufacturer for inspection. No overexposures occurred as a result of this event. Additional information will be provided as it is received in accordance with SA-300."

TRANSFORMER FAILURE CAUSES LOSS OF OFFSITE POWER TO UNIT 2

"At 1201 [CDT], Station Auxiliary Transformer 242-2 experienced a bushing failure, resulting in a loss of offsite power to Unit 2. The 2A and 2B Diesel Generators started and sequenced loads onto the Unit 2 ESF buses appropriately. All other buses normally powered from the Station Auxiliary Transformers automatically transferred to the Unit Auxiliary Transformers. ESF Bus 241 and 242 Undervoltage Relays actuated to start the Diesel Generators and the 2A Auxiliary Feedwater Pump started on the 2A Diesel Generator sequencer. ESF Battery Charger 212 tripped at the same time, which was an unexpected condition. DC Bus 212 was cross-tied with DC Bus 112.

"This notification is being made under 10 CFR 50.72(b)3(iv)(A) due to the actuation of both Unit 2 Diesel Generators and the 2A Auxiliary Feedwater Pump.

"The NRC Senior Resident Inspector has been notified."

Currently, offsite power was restored via the Unit 1 Unit Auxiliary Transformer. Both Unit 2 Emergency Diesel Generators have been secured. DC Busses are still cross-tied.

The licensee is currently in a 72-hour shutdown action statement for the loss of offsite power and a 7-day action statement for having the Unit 2 DC Bus cross-tied to Unit 1.
