MEDICAL EVENT - DOSE 75% OF PRESCRIBED DOSE
A patient was receiving a Y-90 Therasphere treatment to the cancer patient's liver. During the infusion, there was resistance in the tubing. The tubing was disconnected, flushed with a saline solution, and then reattached to the transfer system. The company representative was present during the procedure. After the procedure, the residual activity in the waste was determined to be approximately 25 percent of the total activity. The intended dose to the treatment area was 125 Gy with the actual dose being 94.8 Gy. The prescribing physician and the patient will be notified.
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.

OFFSITE NOTIFICATION DUE TO SODIUM HYPOCHLORITE SPILL ON SITE
"The following event description is based on information currently available. If through subsequent reviews of this event additional information is identified that is pertinent to this event or alters the information being provided at this time a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.
"At approximately 2229 [MST] on April 1, 2016, Arizona Public Service Company completed an offsite notification to the Environmental Protection Agency's National Response Center to report a spill of approximately 8000 gallons of sodium hypochlorite (8% solution) in the vicinity of the Unit 3 cooling towers at the Palo Verde Nuclear Generating Station (PVNGS). Additional notifications were made to Arizona State and Maricopa County environmental authorities.
"The Unit 3 cooling towers are located in the Security Owner Controlled Area at PVNGS and are outside of the protected area. The leak, which resulted from a failed hose on the main hypochlorite distribution header, was stopped by closing a valve to isolate the header. The immediate area has been barricaded. The quantity released exceeded the Reportable Quantity for sodium hypochlorite (RQ of 100 pounds) and was therefore reported. There was no impact to the operation of the PVNGS units or personnel onsite or offsite.
"The NRC Senior Resident has been notified."
