EN Revision Text: OFFSITE NOTIFICATION DUE TO TWO MONITORING WELLS EXCEEDING NEI GPI TRITIUM THRESHOLD VALUES

"At 1340 EDT on October 28, 2021, Watts Bar Nuclear Plant (WBN) Units 1 and 2 initiated voluntary communication to the State of Tennessee and local officials as part of the Nuclear Energy Institute (NEI) Groundwater Protection Initiative (GPI), after receiving analysis results for two on-site monitoring wells that indicated tritium activity above the GPI voluntary communication threshold. The suspected source, a permitted release line, has been isolated, and additional corrective actions are in progress. This condition did not exceed any NRC regulations or reporting criteria. This notification is being made solely as a four-hour, non-emergency notification for a Notification of Other Government Agency. This event is reportable in accordance with 10 CFR 50.72(b)(2)(xi). There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

EN Revision Text: AGREEMENT STATE REPORT - DOSE TO UNINTENDED ORGAN

The following was received from the Commonwealth of Pennsylvania by email:

"On December 10, 2021, the Radiation Safety Officer for the licensee verbally reported a patient being treated for vaginal cancer was prescribed a 21 Gy total dose, to be delivered in 3 fractions of 7 Gy each via HDR [(high dose rate)]. The first fraction was delivered on October 28, 2021. At some point after that treatment, the patient began experiencing complications from the hysterectomy and ended up going to a different hospital for that issue. The patient did not return to the licensee's facility to complete her treatment. At the other hospital, a different Radiation Oncologist was consulted and was reviewing the patient's treatment and discovered that the treatment in October at the licensee was 3 cm off and the intestine received some fraction of the first treatment dose. It was discovered that the patient required re-suturing of the cervix and that the brachytherapy apparatus (used in the HDR treatment) passed beyond the apex of the vagina. This discovery was made yesterday, December 9, 2021. The licensee's medical physicist is currently calculating dose estimates. The referring physician is also being informed. No further information is available at this time. The Department of Environmental Protection will update this event as soon as more information is provided."
