AGREEMENT STATE REPORT - FILTER REPLACEMENT
The following was provided from the State of Tennessee (TN) via email:
"The event occurred in the licensee's Metal Melt Facility (MMF). [The Radiation Safety Officer] RSO noted that a 4 inch by 4 inch section of a HEPA filter from the HEPA filter bank was missing. According to RSO, filter bank was pulling from area that has not been active since February 2017. Air effluent stack sampling and real time monitoring system did not indicate elevated radiation levels. The damaged filter was replaced. Licensee will forward investigation report to the TN Division of Radiological Health upon completion."

AUTOMATIC REACTOR SCRAM DUE TO TURBINE CONTROL VALVE FAST CLOSURE SCRAM SIGNAL
"At 0928 CST on January 10, 2018, the Unit 3 reactor automatically scrammed due to a Reactor Protection System (RPS) signal generated from Turbine Control Valve Emergency Trip System pressure low. The reactor had been operating near 73 percent power for an emergent issue for Turbine Control Valve (TCV) No. 3. With TCV No. 3 out of service and closed, the unit was operating with RPS in a half scram condition. A subsequent failure of the TCV No. 2 sensing line resulted in RPS coincidence logic being met for TCV fast closure SCRAM. The investigation of the TCV No. 2 sensing line failure continues.
"All control rods fully inserted into the core. Main Steam Isolation Valves remained open with Main Turbine Bypass Valves controlling reactor pressure. Reactor Feedwater pumps remained in service to control reactor water level.
"Primary Containment Isolation Signals Groups 2, 3, 6, and 8 containment isolation and initiation signals were received. Upon receipt of these signals all required components actuated as required. Neither High Pressure Coolant Injection nor Reactor Core Isolation Cooling initiation signals were received.
"This event is reportable within 4 hours per 10 CFR 50.72(b)(2)(iv)(B) 'any event or condition that results in actuation of the Reactor Protection System (RPS) when the reactor is critical except when the actuation results from and is part of a preplanned sequence during testing or reactor operation.' It is also reportable within 8 hours per 10 CFR 50.72(b)(3)(iv)(A) and requires an LER within 60 days per 10 CFR 50.73(a)(2)(iv)(A).
"The NRC Resident inspector has been notified."

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN
The following information was received via email:
"On January 12, 2018, GL0704 Pacific Aurora, LLC (formerly Aurora Coop West) contacted [the Nebraska Department of Health and Human Services (NEDHHS)] regarding their overdue Annual Invoice and Current Inventory. The Environmental Manager [EM] noted that Aurora Coop West was bought by Pacific Ethanol on December 16, 2017 and has combined into one entity: Pacific Aurora, LLC. The EM indicated he was unable to locate several of the tritium exit signs on the inventory but would attempt location for one additional week. NEDHHS Office of Radiological Health received written notification on January 25, 2018 of one lost/missing tritium exit sign. The EM assumes the sign may have been moved during a renovation. Should the sign be located, the EM has indicated they will contact [NEDHHS].

Radionuclide: H-3
Activity: 11.5 Ci."
NEDHHS Item Number: NE180002
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
