Event Notification Report for May 01, 2023

AGREEMENT STATE REPORT - GAUGE SHUTTER CAN NOT BE CLOSED DUE TO BROKEN LEVER
The following information was provided by the Texas Department of Health Services (the Department) via email:
"On April 21, 2023, the Department was notified of a gauge with a shutter that could not be moved into the closed position because the lever which moves the shutter broke off. The owner of the gauge reports the lever broke because of corrosion and vibrations. The gauge is a Texas Nuclear 5204 with 8 curies of cesium-137. It is on the side of a dredging vessel that is dredging the entrance channel in Corpus Christi in a 24 hours of work per day operation. During dredging operations, the gauge is normally in the open position and the beam is directed inwards towards the ship. The crew of the vessel normally avoid that side of the vessel and will continue to do so. A survey of the gauge was performed and there is no change. The owner of the gauge reports that they expect the gauge to be repaired by a servicing company on May 9, 2023.
"The Department discussed the possibility of the vessel being docked with the gauge still in the open position and will continue to monitor the situation. Further information will be provided per SA-300.
"The Department will also forward this to the Florida Radiation Control Program as this is a Florida licensee operating in Texas under reciprocity."

Texas incident number: 10013

AGREEMENT STATE REPORT - FOUND RADIOACTIVE SOURCE

The following information was provided by the Colorado Department of Health via email:

"On April 18, 2023, a recycling yard in Denver flagged a load of scrap metal as potentially radioactive. The load was returned to the point of origin and was separated. At that time, a radium-226:beryllium source was identified. The source container was mostly intact. The point of origin (facility name listed above) was able to construct a cement barrier for storing the source until further investigation could be conducted. Measured dose rates around the cement barriers show rates that are indistinguishable from background (gamma and neutron). The markings on the source container indicate the manufacturer as Nuclear Chicago; the model as P21; the activity as 5 mCi radium-226:beryllium; and the reference date as 04/30/1963."

Technical Specification Action 3.6.1.1 Primary Containment Integrity was entered on 04/30/23 at 0100 with a required action to restore primary containment integrity within 1 hour. This required action was not completed within the allowed outage time; therefore, a Technical Specification required shutdown was initiated, and this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(i).
