Event Notification Report for July 15, 2022

AGREEMENT STATE REPORT - DAMAGED TROXLER MOISTURE DENSITY GAUGE

The following information was received via E-mail:

"Kentucky Radiation Health Branch (KYRHB) was notified on 7/15/2022 by the Radiation Safety Officer (RSO) from American Engineers, Inc. that a Troxler 3430 portable Moisture Density gauge (Serial Number 20217; Cs-137: 9 mCi; Am-241/Be: 44 mCi) was severely damaged after it fell off the licensee's truck while leaving a worksite. The gauge was unsecured in an open bed and the tailgate left open, resulting in the gauge falling from the truck to the asphalt and being subsequently run over by a semi-trailer truck. The licensee proceeded to pick up all the debris including the source rod and bottom plate and secured it in the bed of the truck and placed a 55-gallon steel drum over the debris and extended a 15-foot caution zone around the truck, until the Fire Department arrived to scan the area for contamination. No outside contamination was detected on the road and readings were the same as background. The KYRHB inspector arrived about 1630 CDT and conducted independent scans and contamination swipes, and no leakage of either source was detected. The shielding around the Cs-137 source remained intact and readings were as expected from the shielded Cs-137 source. The gauge Tungsten shielding block was placed at the exposed source rod end and taped in place to further reduce possible exposure. The Am-241/Be source remained attached to the bottom housing and scans showed the readings to be nominal, and no removable contamination was detected. The debris was transferred to a plastic bucket and secured in the 55-gallon steel drum and transported to the licensee's facility in Glasgow, KY, and was stored in a room with appropriate signage isolated from the gauge storage area. Readings were checked outside the room to ensure that outside exposure rates were at a minimum. A reactive inspection of the licensee is planned at a future date as a follow-up.

"Reporting Criteria required by 10 CFR 30.50(b)(4)."

Kentucky Event Report ID No.: 220003

FITNESS-FOR-DUTY REPORT

The following information was provided by the licensee via email:

"At 1035 CDT on 7/15/2022, it was determined that a non-licensed supervisor tested positive in accordance with the fitness-for-duty testing program. The individual's authorization for site access has been terminated.

"The NRC Resident Inspector has been notified."

HIGH PRESSURE COOLANT INJECTION (HPCI) INOPERABLE

The following information was provided by the licensee via email:

"At 2020 Eastern Daylight Time (EDT) on July 15, 2022, the HPCI System was declared inoperable. Therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D). The Reactor Core Isolation Cooling (RCIC) System and Automatic Depressurization System (ADS) were operable during this time.

"HPCI availability was restored at 2023. Additional investigation is in-progress.

"There was no impact on the health and safety of the public or plant personnel.

"Unit 2 is not affected by this event.

"The NRC Resident Inspector has been notified."

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

HPCI is considered inoperable but available at this time, resulting in a 14-day Shutdown LCO [Limiting Condition for Operation], due to the HPCI inoperability.

AGREEMENT STATE REPORT - LOST SOURCE

The following information was provided by the Pennsylvania Bureau of Radiation Protection via email:

"On July 15, 2022, the licensee discovered a lost Americium-241 source. The 100 millicurie source is in a FILTEC model FT-50 gauge (Serial Number 116888). During an inventory for its license renewal, the licensee discovered the device missing from its location in storage and has been unable to locate the device. The licensee has notified its facilities and engineering departments, plans on contacting the manufacturer on July 18th to see if the gauge was returned, and is actively searching for the source. The DEP [Department of Environmental Protection] was in contact with the licensee over the weekend for information and will update this event as soon as more information is provided."

Pennsylvania event number: PA220023


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.
