The following information was obtained from the state of Texas via email:
"On April 13, 2018, the Agency [Texas Department of State Health Services] received notice that a radiography camera had an equipment failure yesterday, April 12, 2018. The radiography crew was on a temporary jobsite and was setting up for a job. When the radiographer tried to connect the guide tube, the pigtail on the cable broke and the camera/cable was unusable. The radiographer contacted his radiation safety officer who informed the crew to bring the camera back to the office. The source did not leave the camera. No exposure to an individual occurred. The camera was a Spec-150, #2489 with an Iridium-192 source, G60 -VC1403 at 80 Curies. The manufacturer will be sent the equipment and a full report will be provided by the radiation safety officer within the next few days. Updates will be provide as received in accordance with SA300."

"GNF-A's [Global Nuclear Fuels - Americas] Fuel Manufacturing Operation maintains a safe geometry Radwaste accumulation tank to receive certain liquid discharges from operations. During the annual shutdown work activities and routine inspections, an accumulation of material was identified in a safe geometry Radwaste accumulation tank.
"The accumulation appears to have occurred due to reduced recirculation flow, an engineered feature that mixes the contents of the tank as part of a density control. The accumulation of material is an indication that the tank density control had degraded.
"Plant operations attempted to remove and quantify the material per normal requirements. On 4/12/18 at approximately 1900 [EDT], GNF-A determined that the material could not be quantified in a timely manner.
"In the absence of quantification, GNF-A has conservatively determined that this condition is a failure to meet performance requirements and is therefore reporting it within 24 hours of discovery pursuant to Part 70 Appendix A (b)(2).
"Additional controls on the tank geometry remained intact and at no time was an unsafe condition present. In addition, there are no sources that could result in a rapid addition of uranium to the system.
"Additional corrective actions, extent of condition, and extent of cause are being investigated."
The licensee will be notifying their NRC Program Manager (Vukovinsky), the Radiation Protection Section at North Carolina Department of Health and Human Services, and Hanover County Emergency Management Agency. |

The following information was obtained from the State of Texas via email:
"On April 13, 2018, the Agency [Texas Department of State Health Services] was notified by the Licensee's Radiation Safety Officer (RSO) that an overexposure occurred after a film badge that was sent off earlier this week for an immediate reading came back with a total whole body dose of 6 Rem. On or about April 9, 2018, a radiographer working at a fabrication shop was using a QSA 880D [camera] containing 70 Curies of Iridium-192. After the camera was used to conduct some shots at one location, the radiographer carried the camera and attached cables to a different location. When he walked by a Radiographer Supervisor, the Supervisor's rate alarm starting alarming. The camera was put down, the cranks operated and the source was then fully locked inside the camera. Details of why the source was not fully inserted in the camera are not known at this time. The RSO is enroute to conduct an investigation and interviews on April 16, 2018. The camera and cranks were tested several times and appear to be working normally. No other personnel appeared to receive any significant dose. Additional information will be supplied as it is received in accordance with SA-300."

The following information was obtained from the state of Texas via email:
"On April 13, 2018, the Agency [Texas Department of State Health Services] received notification from a radiation safety officer (RSO) for a radiography company. The RSO stated that they experienced an attempted theft at one of their locations. The workday ended at 6:00 p.m. [CDT] yesterday and began at 6:00 a.m. today. At some point during the night hours, the lock on the complex gate was forced to the point of breakage. The complex is surrounded by a six foot fence and contains radiography vehicles, an office, and a radiography storage vault. The attempt to enter the complex was not successful. The company found the bent/broken lock and noted no items disturbed or stolen. The company informed the local law enforcement servicing the area. The company also increased its video surveillance by adding more cameras and signs communicating the area was under surveillance to deter any future attempts of criminal activity."

The following information was obtained by the state of Texas via email:
"On April 13, 2018, at approximately 8:55 p.m. [CDT], U.S. Customs and Border Protection (CBP) notified the Agency [Texas Department of State Health Services] that it had discovered and identified a cesium [fixed] gauge - Thermo Fisher Scientific Model 5192, containing 200 milliCuries of cesium-137, SN: B8087 - in the bed of a pickup truck of an individual (road construction worker) who was crossing from Texas into Mexico at the Tornillo-Marcelino Serna port of entry in Tornillo, Texas. The individual told the CBP officer that he had found the gauge on the side of the road near Kermit, Texas, and had picked it up and put it in the back of his truck as he was leaving that area to travel to Mexico ('home'); he collects scrap metal and sells it across the border. CBP took possession of the device and the Agency contacted the owner/licensee. The licensee dispatched an employee who retrieved the device at approximately 6:00 a.m. on April 14, 2018. The licensee reported that the device packaging appeared to be secure and has performed a leak test which was sent to a third party for analysis. While there has been no indication that any individual has been exposed above any regulatory limit, the licensee's and Agency's investigations thus far have not been able to definitively make that determination. Therefore, this report is being submitted. More information will be provided as it is obtained in accordance with SA-300."

On Friday, April 20, 2018 at 1042 CDT, Braidwood Station Unit 1 was at 0 percent power in Mode 6. The 1A Diesel Generator (DG) was inoperable with troubleshooting in progress. The 1B DG was being run for a normal monthly run in accordance with 1 BwOSR 3.8.1.2-2, 'Unit One 1B Diesel Generator Operability Surveillance,' and subsequently tripped. The trip was due to a failure of the overspeed butterfly valve actuator and springs, and not an actual overspeed condition. The unit entered Technical Specification (TS) 3.8.2, 'AC Sources - Shutdown,' Condition B for required DG inoperable. All required TS actions were met at the time of the 1B DG inoperability. The offsite power source remains available. At no time was residual heat removal lost.

"On Sunday, April 22, 2018 at 1646 CDT, a valid actuation of Engineered Safety Feature (ESF) Bus 141 Undervoltage (UV) Relay occurred. At the time, Braidwood Station Unit 1 was performing a pre-planned 1A Diesel Generator (DG) Emergency Core Cooling System (ECCS) Actuation Surveillance, initiating the 1A DG to emergency start and sequence loads on a safety injection signal. Following the 1A DG solely supplying electrical power to Bus 141, the 1A DG lost voltage, resulting in an unplanned UV actuation of ESF Bus 141. The 1A DG output breaker was manually opened and local emergency stop of the 1A DG was attempted. The 1A DG continued to run at idle. Fuel supply was secured to the 1A DG and the engine stopped. Subsequently, operators restored power to ESF Bus 141 from the Unit 1 Offsite Power Source. Shutdown cooling was maintained throughout the event as the 1B Residual Heat Removal train was unaffected by the actuation.
"This event is reportable under 10 CFR 50.72(b)(3)(iv)(A) for 'Any event or condition that results in valid actuation of any of the systems listed...', specifically 10 CFR 50.72(b)(3)(iv)(B)(8) for the 'Emergency ac electrical power systems, including: emergency diesel generators (EDGs)...'.
