AGREEMENT STATE REPORT - STUCK SHUTTER
The following was received by the State of Illinois via email:
"The Radiation Safety Officer for Americas Styrencs, LLC, called to report that on September 10, 2019, they were conducting a routine six month shutter check on a Texas Nuclear Model 5180A device and determined that the shutter was stuck in the open position. The device is 40 years old, and it originally contained 2 Curies of Cs-137. The gauge is located on a vessel which is still in active use and is exposed to ambient weather conditions. The gauge is located approximately 10 feet overhead and the beam path is not a routine work location for day-to-day operations. They will contact Thermo MeasureTech to schedule service on the device and apprise the Illinois Emergency Management Agency (Agency) on the service date. Since this device operates continuously, it will continue to function and not interrupt their operations. An Agency inspector arrived on the scene on the same day to confirm that the device was in a safe configuration for continued operations."
Illinois Item Number: IL190028

UNANALYZED CONDITION DUE TO LIGHTNING STRIKE
"A lightning strike occurred at approximately 1502 CDT on 09/10/2019, and a resulting power surge damaged some of the security door card reader system equipment. However, this did not affect access to plant areas for personnel who were already within protected area. At 1830 on 09/10/2019, it was discovered that some of the oncoming night shift personnel could not access particular areas that required the use of security card readers. Extent of condition check at 1934 on 09/10/2019 determined that access to 1A and 3A Electric Board Rooms, which contain remote shutdown panels and Fire Safe Shutdown equipment. was prohibited for the night shift personnel. This condition is reportable under 10 CFR 50.72(b)(3)(ii)(B) - Any event or condition that results in the nuclear power plant being in an unanalyzed condition that significantly degrades plant safety. Access was restored to all plant areas at 2106 on 9/10/2019. No plant
events occurred during the time frame that the 1A & 3A Electric Board Rooms inaccessible that would have required access to these areas.
