Event Notification Report for April 04, 2024

STUCK SHUTTER

The following information was provided by the licensee via phone:

The radiation safety officer (RSO) was showing a new employee the nuclear gauges when they noticed that a gauge was missing a handle. The handle opens and closes the shutter. The RSO believes the shutter may be stuck in the open position. The gauge was manufactured by Burthold in 1995 with model number 7440 and serial number 2964 containing 50 millicuries of Cs-137. There is no additional exposure to plant personnel or the public due to the position of the shutter. Burthold has been contacted for maintenance.

AGREEMENT STATE REPORT - STUCK WELL LOGGING SOURCE

The following information was provided by the Louisiana Radiation Protection Division (the Division) via email:

"On April 4, 2024 at approximately 1619 CDT, the president and radiation safety officer (RSO) of Roke Technologies USA, Inc. [was] working under Louisiana reciprocity when they reported to the Division that at approximately 1400 CDT, two QSA Global 3.0 Ci well logging sources of Americium-241:Be (Model AMN.CY3) contained in the licensee's custom made proprietary logging tool became stuck in tubing at a depth of approximately 1,965 feet. The well, Ronald Richard et ux No. 1, is in Opelousas Field, St. Landry Parish, Louisiana. The E-line holding the logging tool, rated at 3,150 lbs., pulled out of the rope socket on the logging head after the subcontractor logging crew, Verde Services, LLC (Verde) of Laurel, MS, attempted to pull out the tool. The licensee's plan is to meet Verde's braided line truck that is arriving on site at 0800 CDT on April 5, 2024. The braided line is much stronger than the E-line and this truck has a greater pulling strength than the E-line truck. The licensee has high confidence that they will be able to recover the tool as they are also equipped with a fishing neck for the 1-11/16-inch tool which faces upward inside the 2-3/8-inch tubing. The RSO is remaining on site until the tool and sources are recovered. The RSO will follow up with a status report tomorrow morning."

NOTIFICATION OF UNUSUAL EVENT DUE TO FIRE ALARM IN THE VITAL AREA

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

On 4/4/2024 at 1618 MST, a Notification of Unusual Event, HU4.2 was declared based on an unverified fire alarm in the containment building greater than 15 minutes. Palo Verde, Unit 3 was operating in Mode 1 at 91 percent power due to end of cycle coast down to a refueling outage. There is no known plant damage at this time. Offsite assistance cannot enter the containment building, therefore, offsite assistance was not requested. The plant is stable in Mode 1.

The licensee notified State and local authorities and the NRC Senior Resident Inspector.

Notified DHS SWO, FEMA Operations Center, CISA Central, FEMA NWC (email), CWMD Watch Desk (email), DHS NRCC THD Desk (email), and DHS Nuclear SSA (email).

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.
