AGREEMENT STATE REPORT - POSSIBLE DOSE EXCEEDING LIMITS RECEIVED
The following information was received via E-mail:
This event occurred at a field site in or near Orla, Texas.
"On June 23, 2017, the Agency [Texas Department of State Health Services] was notified by the licensee's radiation safety officer (RSO) that an event had occurred involving one of their radiography crews. The RSO stated while performing radiography operations at a field site, a radiographer had approached a SPEC 150 exposure device (camera) containing an 81 Curie iridium-192 source to disconnect the guide tube. After reaching down to disconnect the guide tube, the radiographer noticed the guide tube was not completely attached to the camera and their exposure device (ND 2000 dose rate meter) was pegged high on the times ten scale. The source was then fully retracted to the fully shielded position. The radiographer stated his hand was in close proximity to the guide for about 10 seconds. The radiographer stated his self-reading dosimeter was reading 52 millirem after the event. The RSO stated the radiographers were on their way back to their office. The RSO stated the TLD badges for radiographers would be sent in for reading by their dosimetry processor. The RSO stated the radiographers would be interviewed and the licensee would inform the Agency on Monday, June 26, 2017, what their investigation revealed. The RSO did not have any additional information. Additional information will be provided as it is received in accordance with SA-300.
Texas Incident #: I-9496

The following information was received via E-mail:
"On June 27, 2017, the Agency contacted the licensee and inquired on the status of the radiographer exposed during this event. The licensee's radiation safety officer (RSO) stated they have not seen any changes in the appearance of the radiographer's hands. The RSO stated the radiographer has not felt any discomfort in his hands. The RSO stated a blood sample will be sent to Radiation Emergency Assistance Center/Training Site (REAC/TS) in Oak Ridge, Tennessee, for analysis. Additional information will be provided as it is received in accordance with SA-300."

AUTOMATIC REACTOR SCRAM ON MAIN GENERATOR TRIP
"While performing a scheduled generator voltage regulator test, River Bend Station experienced an automatic scram when the main generator tripped. It is unknown at this time why the main generator tripped.
"There were no equipment issues that materially impacted post scram operator response.
"The intention at this time is to go to cold shutdown while the cause of the trip is investigated."
All rods inserted during the scram. Reactor water level is being maintained via normal feedwater with decay heat being removed via turbine bypass valves to the main condenser. The electrical grid is stable and supplying plant loads via the normal shutdown electrical lineup.
The licensee has notified the NRC Resident Inspector.
