NON-AGREEMENT STATE REPORT - STUCK OPEN SHUTTER
The following is a summary of information that was provided by the licensee via phone:
The licensee's radiation safety officer reported that during a routine maintenance check at approximately 1300 EDT on 10/07/2024, a gauge shutter would not close. The open position is the normal operating position of the shutter. The source contains 100 mCi of Cs-137.
The gauge is in a normally inaccessible location that has been cordoned off until the manufacturer arrives next week for assessment and repair.
A radiation survey confirmed radiation levels are less than 0.06 mrem/hr. There are no radiation exposure concerns to personnel or the public.

The following report was received via phone and email from the Texas Department of State Health Services (the Department):
"On October 8, 2024, the Department was notified by the licensee that the shutter on a Vega model SH-F2 nuclear gauge containing a 200 millicurie [source] (original activity) was stuck in the open position. Open is the normal operation position of the shutter. The licensee reported there is no risk of additional radiation exposure to members of the general public or radiation workers due to this on/off mechanism failure.

AGREEMENT STATE REPORT - STOLEN SOIL DENSITY GAUGE
The following report was received via email from the Maryland Department of the Environment (MDE):
"On October 9, 2024, at 1549 EDT, the MDE emergency response center received a telephone report of a suspected stolen soil density gauge was captured by police. The report came from the Prince George's County Police to get guidance on the subject. MDE has called the Prince George's County Police contact person and are waiting for a response. Details about the gauge are not yet available.
"This report is based on 10 CFR 20.2201(a)(1)(i) because soil density gauges have a typical activity of 9 mCi of Cs-137 and/or 44 mCi of Am-241.
"An investigation will be conducted and follow up reports are to be expected."
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.

NONCOMPLIANCE WITH TECHNICAL SPECIFICATION
The following information was provided by the licensee via phone and email:
"University of Missouri Research Reactor (MURR), a 10 MW reactor, is reporting an abnormal occurrence as required per Technical Specification (TS) 1.1 b and c. One of two redundant switches on the Fluxtrap irradiations reactivity safety trip device failed reactor pre-startup checks on October 14, 2024. This failure would have prevented the switch from sending a scram input to the reactor protection system. MURR TS 3.2.g.21 requires a 1/N logic of 2, meaning both switches must be operational during operation of the reactor.
"The faulty switch was last confirmed operating properly prior to reactor startup on October 7, 2024. MURR cannot positively state when the switch failed. This condition could have existed during operations at some point between October 7 and October 13, 2024.
"The second switch was verified to be operable. The faulty switch and its associated wiring were replaced, retested satisfactorily, and the reactor was returned to operation the evening of Monday, October 14, 2024 with authorization from the Facility Director.
"MURR will follow up with a written report to the NRC within 14 days as required by TS 6.6.c.
"NRC Project Manager has been notified."
The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
A causal investigation is in progress. Equipment age is the potential cause of the failure.
