LOST TRITIUM EXIT SIGNS

The following information was provided by the licensee via phone and email:

"Two tritium exit signs cannot be located at Bridger Coal Mine in Point of Rocks, Wyoming. The signs are believed to have been returned to the manufacturer following use, but there is no paperwork to confirm. Efforts to ascertain knowledge of the purchase or return of the devices from the manufacturer were fruitless. Bridger Coal Mine does not have intentions now, or in the future, to posses generally licensed devices."

The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:

Each exit sign contained 7.5 curies of tritium.

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.

EN Revision Text: AGREEMENT STATE REPORT - LOST GAUGE

The following information was provided by the Florida Bureau of Radiation Control (BRC) via email and phone:

"On September 18, 2024, at 1345 EDT, BRC received call from the licensee's radiation safety officer (RSO), that an employee noticed their soil moisture density gauge [containing 10 mCi of Cs-137 and 50 mCi of Am-241:Be] was missing from the back of their pick-up truck at 1215 while traveling between job sites. The employee left a job site at the intersection of Triton and Roma in Port Saint Lucie and noticed the gauge missing at the intersection of Kanner Hwy and I-95. The employee called their supervisor at 1230, who in turn called the RSO at 1330. The employee admitted that the gauge case was not chained to truck, but that the gauge was secure in the case which had two locks on it. The employee retraced their route several times, but could not locate the gauge.

"BRC will assign an inspector to respond."

Device Information:
Device type: soil moisture density gauge
Manufacturer: CPN
Model Number: MC-DR
Serial number: MD40107276

Florida incident number: FL24-092

* * * UPDATE ON 9/25/2024 AT 1511 EDT FROM MARK SEIDENSTICKER TO TENISHA MEADOWS * * *

"On September 25, 2024, at 1440 EDT, BRC was notified that the gauge had been returned. A worker on the job site returned the gauge in its case on September 25, 2024. The gauge was intact. A latch on the case was broken off, but the other latch was intact with a lock on it."

HIGH PRESSURE CORE SPRAY INOPERABLE

The following information was provided by the licensee via phone or email:

"On September 24, 2024, at 2204 CDT, Grand Gulf Nuclear Station (GGNS) was conducting surveillance testing on the high pressure core spray (HPCS) division III diesel generator. During testing, the HPCS pump breaker unexpectedly tripped after the HPCS diesel generator started and powered the safety bus. The breaker performed its motor protection function and tripped due to an over-frequency indication.

"The event is being reported in accordance with 10 CFR 50.72(b)(3)(v)(D) as an event or condition which could have prevented the fulfillment of a safety function.

"Troubleshooting is in progress. HPCS, a single-train system, will remain inoperable until the condition is corrected.

"All sources of offsite power are available. No other safety systems are inoperable. Reactor core isolation cooling was verified to be operable per GGNS Technical Specification 3.5.1.B.1.

"The NRC Senior Resident has been notified."

"At approximately 1110 EDT, on September 25, 2024, the New Hanover County Deputy Fire Marshall was notified that a non-IROFS (Item Relied On For Safety) fire door was damaged and incapable of fulfilling its function. Specifically, the door will not close properly and seal with the opposing door. A fire watch was initiated and a replacement door is being obtained. Because the New Hanover County Deputy Fire Marshall was notified, a concurrent notification to the NRC Operations Center is being made per 10 CFR 70, Appendix A(c)."

The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:

The licensee plans to notify the NRC Region 2 office and the state of North Carolina concerning this event report.
