WRITTEN DIRECTIVE FOR MICRO-SPHERE LIVER TREATMENT WAS INCORRECT

On 7/24/19 while preparing to administer micro-sphere liver treatment the health physicist discovered that the paperwork for a previous treatment on a different patient was incorrect. The paperwork indicated that the treatment was for the left lobe of the liver. The patient's left liver was removed in a previous surgery. The prescribing physician realized that the treatment was for the right lobe of the liver and administered treatment to the right lobe. The physician failed to correct the paperwork. The treatment was on 7/2/19. The prescribed dose was 0.77 GBq and the administered dose was 0.78 GBq. There was no harm to the patient.

The licensee notified the NRC R1 Office (Tara Weidner, Penny Lanzisera).

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.

INVALID CONTAINMENT VENTILATION ISOLATION ACTUATION

"This 60-day telephone notification is being submitted in accordance with paragraphs 10 CFR 50.73(a)(1) and 50.73(a)(2)(iv)(A) to report an invalid Containment Ventilation Isolation (CVI) actuation at Watts Bar Nuclear Plant (WBN) Unit 2.

"On July 26, 2019, at 1003 Eastern Daylight Time (EDT), the Train A CVI actuated due to an invalid High Radiation signal from 2-RM-90-130, Containment Purge Air Exhaust Monitor. Prior to and following the invalid High Radiation alarm, all radiation monitors except 2-RM-90-130 were stable at their normal values. All required automatic actuations occurred as designed. Upon investigation, the cause of the invalid High Radiation alarm was due to a failed ratemeter for 2-RM-90-130.

"Control room operators performed appropriate checks and confirmed that the subject indication was an invalid high radiation signal. The ratemeter for 2-RM-90-130 was replaced and the monitor returned to service. At the time of the event, plant conditions for a High Radiation alarm did not exist; therefore, the CVI was invalid.

"The NRC Resident Inspector was notified."
