EN Revision Text: AGREEMENT STATE REPORT - DAMAGE TO PORTABLE MOISTURE DENSITY GAUGE

The following was received from the Virginia Radioactive Materials Program (VRMP) via email:

"On July 22, 2021, at 0950 EDT, VRMP received a report via telephone from the Radiological Duty Officer of the Virginia Office of Radiological Health that a portable nuclear moisture/density gauge was damaged when hit by a car at a temporary jobsite. At 1000 EDT, the VRMP contacted the Radiation Safety Officer (RSO) of the licensee. The RSO stated that a Troxler density gauge (Model 4640-B, serial number 2266, containing 8 milliCuries of cesium-137) was hit by a car at a temporary jobsite. The gauge housing was damaged, but the source appeared to remain intact within the safe position. The licensee's survey of the gauge yielded readings of 0.02 mR/hr at about a foot distance from the gauge. The gauge was taken to the licensee's office in its transport container. A survey was also performed on the ground and the reading was reported as background. The gauge will be tested for leakage and after testing, it will be sent to the Troxler Electronics Laboratories for evaluation. The VRMP is working with the licensee to obtain additional information. This report will be updated once the licensee's investigation is complete and the information is received by the VRMP. According to the RSO, no public or personnel exposure occurred."

EN Revision Text: UNANALYZED CONDITION OF FIRE SAFE SHUTDOWN EQUIPMENT

"On July 20, 2021, at 1707 EDT, an apparent non-compliance with 10 CFR 50, Appendix R, section III.G.2 (separation of redundant fire safe shutdown equipment) was identified. This issue was initially categorized as not affecting train separation or the ability of the equipment to perform their Design Basis functions. The original concern was entered into the licensee's Corrective Action Program as CR1177199.

"Subsequently, on July 22, 2021, at 1751 EDT, a further review of the affected control circuits for the Unit 1 and Unit 2 Emergency Diesel Generator (EDG) output breakers and emergency bus feeder breakers identified a concern that breaker position interlocks routed to or through non-safety related components or spaces may affect the ability to provide emergency power on the affected unit due to impacts on the control power circuits during an Appendix R fire associated with a loss of offsite power.

"The following are the affected fire areas:
- Unit 1 and Unit 2 Turbine Buildings
- Unit 1 and Unit 2 Cable Spreading Rooms
- Unit 1 and Unit 2 Normal (307) Switchgear Rooms

"This condition is being reported pursuant to 10 CFR 50.72(b)(3)(ii)(B). This is also reportable as a 60-day written report pursuant to 10 CFR 50.73(a)(2)(ii)(B). This event was entered into the licensee's Corrective Action Program as CR 1177399.

"The NRC Resident Inspector has been notified of this event."

EN Revision Text:
AGREEMENT STATE REPORT - PATIENT UNDER DOSE

The following was received via an email from the Pennsylvania Department of Environmental Protection (DEP) via email:

"On July 22, 2021 a patient was receiving a Lutetium-177 (Lutathera) treatment when technicians had difficulty establishing an IV injection site and flow. Several attempts were made, but ultimately they all failed. The prescribed dose was 200 milliCuries, but it is estimated that the patient received only 18 millicuries. No adverse effects to the patient are noted at this time and none are expected. The patient and prescribing physician have been informed. Preliminary cause is suspected to be poor venous access for patient as well as incorrect gauge needle used for patient access. The DEP will update this event as soon as more information is provided.

"The Department will perform a reactive inspection."
