AGREEMENT STATE REPORT - MISADMINISTRATION DURING HIGH DOSE RATE PROCEDURE

The following information was received via facsimile:

"At approximately 1355 PST on Friday, 12/30/2016, Seattle Cancer Care Alliance called the Washington State Radioactive Materials Section to report a medical event. The event had occurred on Friday, 12/23/2016 but the date that the event was discovered was not provided. The summary of the event is as follows: An Ir-192 source was incorrectly positioned during an HDR procedure, resulting in a reduced dose to the treatment volume and an unintended dose to the surrounding healthy tissue. Limited information was provided by the licensee because they are still investigating the misadministration, but additional information will be provided in a follow-up conversation on Tuesday, 1/3/2017."

Washington Incident Number: WA-16-049

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

EMERGENCY DIESEL GENERATORS NON-CONFORMING WITH LICENSING BASIS FOR TORNADO GENERATED MISSILES

"On January 9, 2017, during evaluation of protection for Technical Specification (TS) equipment from the damaging effects of tornado generated missiles, Peach Bottom Atomic Power Station identified a non-conforming condition in the plant design such that specific TS equipment is considered to not be adequately protected from tornado generated missiles. A tornado could generate multiple missiles that could strike one or more of the four emergency diesel generator (EDG) exhaust stacks. This could result in crimping of the stack, which could affect the ability of the EDG to perform its design function if such a tornado would occur.

"This condition is reportable per 10 CFR 50.72(b)(3)(ii)(B) for any event or condition that results in the nuclear power plant being in an unanalyzed condition that significantly degrades plant safety, and per 10 CFR 50.72(b)(3)(v)(D) for any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.

"This condition is being addressed in accordance with NRC enforcement guidance provided in EGM 15-002 and DSS-ISG-2016-01. Compensatory measures have been implemented in accordance with these documents.

"The NRC Resident Inspector has been informed of this notification."
