NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - UNABLE TO RETRACT SOURCE
The following information was received from the State of Texas via email:
"On August 12, 2018 at approximately 1135 [CDT]., the licensee notified the Agency [Texas Department of State Health Services] that one of its radiography crews had experienced a source disconnect. The event occurred on August 11, 2018, at approximately 1200 [CDT] at a temporary job site near Whitsett, TX. The device involved was an INC IR-100 (SN: 6792) containing a 91 curie iridium-192 source (SN: ZH0109). The crew had set up the device and performed a procedure shot and everything functioned properly. They performed the first shot of the job and the source would not retract into the device--it felt as though it had stuck on something. After a second unsuccessful attempt, the source was cranked back out into the collimator, boundaries set, and an authorized person came to the site and performed the retrieval. The drive cable and source were both new. There was no observable cause for the failure. The device and associated equipment will be sent to the manufacturer for evaluation. Per readings from all three individuals' self-reading pocket dosimeters, there were no overexposures. The source retriever's dosimetry badge is being sent for processing. An investigation into this event is ongoing. More information will be provided as it is obtained in accordance with SA-300."

"At 0943 EDT on August 22, 2018, the Watts Bar Unit 2 reactor automatically tripped while operating at 100 percent power. All control and shutdown bank rods inserted properly in response to the automatic reactor trip. All safety systems including Auxiliary Feedwater actuated as designed. The plant is stable with decay heat removal through Auxiliary Feedwater and Steam Dump Systems.
"The reactor automatically tripped due to a main turbine trip signal. An investigation is in progress.
"The automatic actuation of the Reactor Protection System (RPS) is being reported as a four-hour report under 10 CFR 50.72 (b)(2)(iv)(B).
"The expected actuation of the Auxiliary Feedwater System (an engineered safety feature) is being reported as an eight-hour report under 10 CFR 50.72 (b)(3)(iv)(A).

"On 08/22/2018 at 1803 hours CDT, Browns Ferry Nuclear Plant declared an Unusual Event per EAL HU4, a fire potentially degrading the level of safety of the plant.
"At 1748 CDT Unit 1 received a call reporting smoke coming from the 480V Condensate Demineralizer Panel 3 in the Unit 3 turbine building elevation 557'. At approximately 1803 [CDT], the incident commander on the scene confirmed a fire inside the panel and all three units entered 0-AOI-26-1, Fire Response. The board was subsequently de-energized by operations personnel and the fire was extinguished at 1806 CDT. SM [Shift Manager] exited EAL HU4 and all three units exited 0-AOI-26-1 at 1840 CDT.
"Fire operations remain on scene to monitor. A team is being assembled for damage assessment and recovery.
"The fire did not affect any safety systems, no plant transients resulted, and no injuries were reported.
"This event is reportable within 1 hour IAW 10 CFR 50.72(a)(1)(i).
