"Unit 2 reactor scrammed at 13:13 [EDT] following an electrical yard manipulation. The reactor scram occurred as a result of an RPS [Reactor Protections System] actuation following an automatic trip of the main turbine from a generator lockout. All control rods inserted [fully]. The plant is stable [in mode 3]. No ECCS [Emergency Core Cooling System] or safety relief valve actuations have occurred. This report is being made pursuant to 50.72(b)(2)(iv)(b). At this time the plant is stable, as expected. An investigation is in progress to determine the reason for the electrical fault."
All plant systems functioned as required and decay heat removal is being performed via bypass to the main condenser.
The licensee notified local and State authorities and the NRC Resident Inspector. |

"On June 21, 2004, at approximately 0830 hours, testing of High Pressure Coolant Injection (HPCI) system instrumentation commenced per Maintenance Surveillance Test 2MST-HPC128R, 'HPCI Reactor Water Level Channel Calibration And Functional Test.' At 0900 hours, it was determined that the instrumentation would require corrective maintenance and Technical Specifications (TS) Limiting Condition for Operation (LCO) 3.3.5.1, 'Emergency Core Cooling System (ECCS) Instrumentation,' Condition C was entered for HPCI system Reactor Vessel Water Level - High instrument channel 2-B21-LTN017B-2. Required Action C.2 of TS LCO 3.3.5.1 provides 24 hours for the channel to be returned to operable status. On June 22, 2004, at 0900 hours, the instrument channel was not returned to operable status due to continuing maintenance activities to calibrate the channel. Therefore, Condition G of TS LCO 3.3.5.1 (Required Action and associated Completion Time of Condition C not met) was entered and the High Pressure Coolant Injection (HPCI) system was declared inoperable in accordance with TS LCO 3.3.5.1 Required Action G.1.
"TS LCO 3.5.1. "ECCS - Operating," Condition D was entered for the HPCI system being declared inoperable. The Reactor Core Isolation Cooling (RCIC) system was verified operable per Required Action D.1. Required Action D.2 of TS LCO 3.5.1 requires the HPCI system to be returned to operable status within 14 days. The [NRC] Resident Inspector has been notified.
"The initial safety significance of this condition is considered to be minimal. The HPCI System is still available during maintenance activities. The RCIC system, as well as all other required ECCSs, are operable at this time.
"Maintenance activities and post maintenance testing were completed at 14:55 on June 22, 2004 allowing the HPCI System to be restored to an operable status." |

Thallous Chloride (4 mCi of Tl-201) was injected into a patient without a prescription. A technician asked the patient before administering the dose if he/she was the person on the prescription. The patient responded positively. The technician administered the dose to the patient without checking the patient's wrist-band identification to confirm the patient's identity. The Thallous Chloride was prescribed to a different patient in preparation for an X-ray examination of the heart.
The physician notified the patient that he/she inadvertently received a 4 mCi dose of Thallous Chloride. The physician determined that no medical treatment was required to treat the effects of the misadministered dose. The technician has received counseling, a copy of the hospital's identification policy, and a written warning as a corrective measures action. | |
