Event Text

MEDICAL EVENT WRITTEN DOSE DIRECTIVE IS DIFFERENT THAN PRESCRIBED DOSE

An endocrinologist specified a therapy dose of 20 milliCuries of I-131. An authorized dose directive was incorrectly written for 30 milliCuries of I-131. The patient was administered the initially determined dose of 20 milliCuries of I-131. Medical personnel determined that there was no impact on the patient.

Hospital supervision notified the on-site Authorized User, the Radiation Safety Officer and the Medical Physicist.

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.

PERRY COMMENCED TECHNICAL SPECIFICATION REQUIRED SHUTDOWN

"On October 4, 2017, at 0250 hours [EDT], the Perry Nuclear Power Plant commenced a Technical Specification (TS) shutdown by lowering reactor power from 100 percent rated thermal power to 98 percent to comply with TS LCO 3.0.3. Reactor power was further reduced to 82 percent rated thermal power at 0430 hours [EDT].

"The plant had entered TS 3.0.3 at 0155 hours [EDT] upon loss of MCC [Motor Control Center], Switchgear, and Miscellaneous Electrical Equipment Areas HVAC System train A while train B was removed from service for maintenance. MCC switchgear ventilation train A was declared inoperable based on excessive belt noise and a dropped belt on MCC switchgear supply fan A. This also constitutes a loss of safety function.

"This event is being reported in accordance with 10 CFR 50.72(b)(2)(i) and 10 CFR 50.72(b)(3)(v)(D).

"The NRC Resident Inspector was notified."


* * * UPDATE ON 10/04/17 AT 0926 EDT FROM DAN HARTIGAN TO STEVEN VITTO * * *

"Due to the loss of both trains of MCC, Switchgear, and Miscellaneous Electrical Equipment Areas HVAC, actions were taken in LCO 3.8.7 for AC and DC Distribution Systems, LCO 3.8.4 for DC Sources, LCO 3.8.1 for AC Sources, and the associated support systems, the High Pressure Core Spray system was also declared inoperable, which is a single train safety system and therefore, an additional loss of safety function.

"This event is being reported in accordance with 10 CFR 50.72(b)(3)(v)(B), 10 CFR 50.72(b)(3)(v)(C) and 10 CFR 50.72 (b)(3)(v)(D).

"At 0620 hours [EDT] the A train of MCC, Switchgear, and Miscellaneous Electrical Equipment Areas HVAC and High Pressure Core Spray was declared operable and LCO 3.0.3 was exited. The plant was restored to 100% [percent] power at 0804 [EDT].

"The NRC Resident Inspector was notified."
