| Event Text AGREEMENT STATE - CALIFORNIA - MEDICAL MISADMINISTRATION
The State provided the following information via facsimile:
"On March 16, 2007, the licensee initiated a 'Mammosite' treatment of a patient, with a total prescribed dose of 3400 cGy (3400 rad) to be delivered in 10 fractions of 340 cGy (340 rad) each, over the course of 5 days, using a Nucletron, Model 105.999 HDRA with 4.1 Ci Ir-192 (as of the first day of treatment). The first five fractions were delivered uneventfully. During the last five fractions, the radiation therapy technologist accidentally imported the wrong treatment plan, resulting in an underdose to the treatment area. The dwell position of the source was actually fully outside of the patient, so the tumor received effectively no dose. The licensee is calculating the skin and whole body dose to the patient, but currently estimates it will not have an adverse affect upon the patient. The patient and referring physician have been notified, and re-treatment has been scheduled to begin tomorrow. This event was discovered upon review of the patient's chart when the patient returned for a follow-up exam. The licensee will provide a written report of the event within 15 days."

| Event Text AGREEMENT STATE REPORT FROM OKALAHOMA - HIGHER DOSE THAN PRESCRIBED
This event took place between 05/03/06 and 03/27/07 and involved ten patients during this time period being treated for prostate cancer using Iodine-125. Kay County Hospital LLC (formally known as Via Cristi Hospital) had changed from ordering I-125 doses in Air-Kerma to millicuries. During the time period from 05/03/06 to 03/27/07 they used the incorrect dose count. This caused each of the ten patients to receive a dose 27 percent higher than the written directive. This did not pose any harm to the patients. The error was discovered on 03/28/07 by a newly hired Medical Physicist.
The licensee is in the process of notifying the affected patients. The licensee will also being working with the software vendor to develop better training and procedures for the performance of dose calculations to prevent reoccurrence.

"The possible medical event occurred at a broad-scope permittee authorized under the master materials license issued to the Department of Veterans Affairs, NRC License 03-23853-01VA.
"The permittee is VA Eastern Colorado Health Care System, Denver, Colorado. The possible medical event occurred on May 31, 2006. The possible medical event was discovered on March 28, 2007.
"The basis for the possible medical event is under 10 CFR 35.3045(a)(1)(i) and involved administration of a dose different from the dose prescribed in the written directive.
"Specifically, the written directive for a patient therapy procedure listed the dose to be 15 millicuries Iodine 131 when in fact 30 millicuries was given to the patient. Since the clinical intent was for the patient to receive 30 millicuries, the possible medical event will not have any adverse impact on the patient.
"The permittee has implemented corrective actions to prevent a recurrence of the circumstances that resulted in the possible medical event.
"The Department of Veterans Affairs will evaluate the circumstances related to the possible medical event and submit a written report to NRC, Region III, within 15 days."

| Event Text PART 21 - ROSEMOUNT PRESSURE TRANSMITTER MAY NOT BE SEISMICALLY QUALIFIED
"During routine operations on the RNII production floor, it was observed that an incorrect torque wrench was being used at mechanical assembly to tighten the Sensor Module Lock Nut. The incorrect tool was calibrated to a value of 12.5 ft-lb, resulting in undertorquing of the lock nut. The incorrect torque wrench was removed from service and replaced with a tool calibrated to the correct torque value of 35 ft-lb. RNII reworked all affected transmitters that had not yet shipped to the correct torque value.
"Assembly with the incorrect tool could result in certain pressure transmitters having a degraded environmental seal between the sensor module and the electronics housing during or after a seismic event."
The five affected models have been delivered to the Byron and Comanche Peak nuclear stations. |

"At approximately 0740 on 3/30/2007, a segment of the inside Criticality Warning System (CWS) covering the Fuel Manufacturing Operation (FMO) failed due to an apparent voltage fluctuation in the power supply to the system. The fluctuation resulted in activation of the CWS evacuation alarm.
"All personnel promptly evacuated the facility and the emergency organization assembled in accordance with normal procedures. A total of 5 out of 6 FMO CWS Data Acquisition Modules (DAMS) were affected by apparent power supply fluctuation. Two additional DAMS, which are independent, continued to provide coverage of the Dry Conversion Process (DCP) process areas.
"The Emergency Director determined that the processes should stay shut down and all personnel not engaged in troubleshooting or recovery actions remain out of the area while investigations and additional testing was conducted. Follow-up tests replaced select hardware, and installed additional power supply monitoring equipment to aid diagnostics. All DAMS have been successfully reset and the inside FMO CWS system returned to normal operation.
"Current plans are to resume normal operations beginning with the 1500 (evening) shift.
"The event is being reported within 24-hours pursuant to 10CFR70.50(b)(2) as a safety equipment failure."
The licensee will also be providing a courtesy notification to the North Carolina Department of Radiological Protection and the New Hanover County Emergency Management organization. |

| Event Text SAFETY EQUIPMENT FAILURE - PROCESS GAS LEAK DETECTION SYSTEM
"At 1030, on 3-30-07 the Plant Shift Superintendent was notified of the failure of the C-333A Process Gas Leak Detection (PGLD) detector head YE-613-21. Detector head YE-613-21 is located in the piping trench between the autoclaves. The trench detector heads are scheduled to be replaced at a six month interval. Operators were performing an "as-found" test on the head prior to scheduled replacement. The detector head did not alarm as required when smoke was applied during the test. The Process Gas Leak Detection system is required to be operable according to TSR 2.2.4.1.
"This event is reportable as a 24 hour event in accordance with 10CFR 76.120(c)(2)(l). This is an event in which equipment is disabled or fails to function as designed when: a.) the equipment is required by a TSR to prevent releases, prevent exposures to radiation and radioactive materials exceeding specified limits, mitigate the consequences of an accident, or restore this facility to a pre-established safe condition after an accident; b.) the equipment is required by a TSR to be available and operable and either should have been operating or should have operated on demand, and c.) no redundant equipment is available and operable to perform the required safety function."
The YE-613-21 detector head was replaced approximately 6 months ago and was last known to be functional approximately one month ago after some wiring tests were conducted in the area of the detector head. The permittee is conducting failure cause analysis to determine failure mode and possibly identify when failure occurred.
The NRC Senior Resident Inspector has been notified of this event.

"During post-maintenance operability testing, Diesel Generator 4 exhibited unstable power output while synchronized to the grid. This testing was being performed at the conclusion of a planned Diesel Generator 4 maintenance outage. Preventive maintenance activities included in this scheduled outage included replacement of various relays in the Diesel Generator control logic and replacement of the engine governor.
"Brunswick Nuclear Plant Unit 1 is commencing a unit shutdown as required by Technical Specification 3.8.1 Condition H due to the inoperability of Diesel Generator 4 lasting longer than seven (7) days. TS 3.8.1 Required Action H.1 requires Unit 1 to be in MODE 3 by 1615 on 4/1/2007 and in MODE 4 by 1615 on 4/2/2007. This event is reportable per 10CFR50.72(b)(2)(i).
"Power reduction was commenced at 1045 in accordance with station procedures for unit shutdown. Power level has been reduced from 100% to 53%. Unit 1 shutdown will continue until the unit is in MODE 4 or until the engine is declared operable following appropriate repairs and testing.
"Unit 2 is in MODE 4, Cold Shutdown. The inoperable Diesel Generator 4 is not needed to meet the requirements of Unit 2 Technical Specification 3.8.2.
"The inoperability of Diesel Generator 4 is of minimal safety significance for Unit 1. Unit 1 has two operable off-site circuits and three (3) Diesel Generators are operable. The remaining three (3) operable Diesel Generators and off-site circuits are adequate to supply electrical power to the on-site Class 1 E Distribution System. This maintains the safety function of the AC sources. Unit 1 is being shutdown to place the unit in MODE 4 where the inoperable Diesel Generator 4 is not required. Unit 2 is currently in MODE 4 and does not require Diesel Generator 4 to be operable. As such, this event is of zero safety significance for Unit 2.
"During post-maintenance operability testing, Diesel Generator 4 exhibited unstable power output while synchronized to the grid. Station engineering and a vendor representative continue to evaluate the engine/generator performance. Repair plans will be developed and implemented as appropriate following completion of the engineering evaluation."
The inoperability of Diesel Generator 4 will prevent Unit 2 from changing mode for returning the plant to service.
The licensee notified the NRC Resident Inspector. | |
