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. | Power Reactor | Event Number: 51861 | Facility: PALO VERDE Region: 4 State: AZ Unit: [1] [ ] [ ] RX Type: [1] CE,[2] CE,[3] CE NRC Notified By: KYLE ROSEK HQ OPS Officer: VINCE KLCO | Notification Date: 04/11/2016 Notification Time: 15:37 [ET] Event Date: 04/11/2016 Event Time: 05:35 [MST] Last Update Date: 04/11/2016 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(3)(ii)(A) - DEGRADED CONDITION | Person (Organization): RAY AZUA (R4DO) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | N | N | 0 | Cold Shutdown | 0 | Cold Shutdown | Event Text REACTOR PRESSURE BOUNDAY LEAKAGE "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 2335 [MST] on April 10, 2016, while performing planned routine visual examinations of Unit 1 components in the Containment Building, engineering personnel identified white residue on the piping instrument nozzle for the reactor coolant system (RCS) 2B cold leg resistance temperature detector, 1JRCET121Y. The white residue was dry and no active leakage was noted on the instrument nozzle. "Preliminary chemical analysis for radionuclide and boron content of the white residue determined the existence of boron and the isotopic content was consistent with RCS fluid. At 0535 [MST] on April 11, 2016, it was determined the residue resulted from RCS pressure boundary leakage, based on results of the chemical analysis and additional examination of the piping and instrument nozzle by qualified engineering personnel. Technical Specifications Limiting Condition of Operation (LCO) 3.4.14 permits no RCS pressure boundary leakage and therefore, the discovery of leakage from the instrument nozzle represents a degradation of a principal safety barrier. This notification is being made for a degraded condition pursuant to the requirements of 10CFR 50.72(b)(3)(ii)(A). "The unit has been shut down for its 19th refueling outage since 4/9/16 at 0000. "The NRC resident inspectors have been informed of this condition." | |
