"On August 22, 2025, the Louisiana State Police notified LDEQ that Smitty's Supply Inc. in Roseland had an explosion and was on fire. The explosion and fire resulted in significant damage to the facility.

"At the time of the incident, three nuclear gauge devices, each containing 100 mCi of Americium 241, were present onsite. These gauges could potentially be affected. The fire was finally extinguished on August 25, 2025. An entry team, including a radiation inspector, will enter the facility today, August 26, 2025, to verify/confirm the status of the gauges and radioactive material."

AGREEMENT STATE REPORT - FIXED GAUGE SHUTTER MISSING

The following is a summary of information provided by the New Mexico Radiation Control Bureau via phone and email:

During a routine inspection, the licensee discovered that the normally open shutter on a fixed gauge installed on a pipeline was missing. The gauge remains installed and is operating normally. All planned maintenance in the area of the gauge has been suspended. The licensee has been instructed to obtain the assistance of properly trained and qualified personnel to assist with corrective actions.

Gauge: Texas Nuclear model 5190, s/n B3309
Source: Cs-137, 100 mCi

AGREEMENT STATE REPORT - MEDICAL EVENT

The following information was provided by the Radiation Health Branch of the Kentucky Department for Public Health and Safety via email:

"On August 26, 2025, the University of Kentucky (UK) Health Center radiation safety officer became aware of a situation that represents what UK believes are a series of possible medical events which occurred from August 22 to August 25, 2025, related to nuclear medicine administrations requiring written directives. Within this date range, a new faculty physician who was in the process of becoming approved as an authorized user (AU) through the UK radiation safety committee (RSC) signed 5 written directives (3 for diagnostic I-131 procedures with a nominal activity of 5 mCi, and 2 for Lu-177 therapy at a 100 mCi activity) despite not having yet received approval under the UK medical broad scope license from the UK RSC. The cases have all been reviewed by a senior AU and no patient harm has been identified. The physician in question has since received approval from the UK RSC. Notifications are in process as required.

"This event is under investigation. University of Kentucky will complete an assessment and implement corrective actions.

"The written report will follow as required in 15 days."

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

CONCURRENT REPORT FOR OFFSITE NOTIFICATION

The following is a summary of information provided by the licensee via phone and email:

Centrus American Centrifuge Operating (ACO) received notification from a Fluor-BWXT Portsmouth (FBP) environmental technician supervisor that the chlorine level at outfall '013' was at 0.063 mg/L. This exceeds the National Pollutant Discharge Elimination System permit limit on total chlorine at outfall '013' of 0.05 mg/L. Centrus ACO notified the Ohio Environmental Protection Agency at 1450 EDT.

Elevated chlorine levels at outfall '013' were initially noted and reported on August 18, 2025, under EN 57874. Centrus ACO has since determined that a sanitary line break that went into a holding pond is the cause of the elevated chlorine levels. Elevated chlorine levels observed today are attributed to residual chlorine upstream of the outfall.

This report is in accordance with condition notification #12816.

The NRC regional office was notified.
