| Event Text AGREEMENT STATE REPORT INVOLVING A POTENTIAL MEDICAL EVENT DURING BRACHYTHERAPY
The following information was received from the State of Ohio via email:
"The Ohio Department of Health Bureau of Radiation Protection received a preliminary telephone report from the University of Toledo of a device malfunction with a Varian HDR with an Ir-192 source. A patient had received four treatments to the cervix. The physician noticed during examination reddening of the skin on the upper thigh. Upon reviewing the setup with the tandems, a constriction and blockage was identified in the catheters caused by wear debris. It is presumed at the time being that this caused the system to conclude the source had reached the end of the catheter when it had not. Dose calculations are in the process of being reviewed, however the licensee believes that the doses may be less than the quantities for a medical event.
"The licensee is The University of Toledo, Ohio license number 02110 49 0006.
"The licensee is preparing a written report. The Bureau will be sending an inspector to the site next week."
Ohio Report # OH-12-001
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. |

| Event Text AGREEMENT STATE REPORT - DOOR SAFETY INTERLOCK ON DRY IRRADIATOR FOUND TO BE NON-FUNCTIONAL
The following report was received via e-mail from the Illinois Emergency Management Agency Radioactive Materials Section:
"The licensee's radiation safety officer called the Agency to advise of a failure of a safety feature associated with the operation of their self shielded dry storage irradiator. This irradiator is used to conduct testing of samples prior processing. During the performance of routine weekly safety checks of the irradiator, it was discovered that the device could be operated without closing both shielded collar doors that allow access to the sample chamber. Further investigation showed that a proximity sensor associated with one of the doors failed in the 'on' configuration which gave a false indication that the unit was ready for operation and the irradiation sequence could be initiated. No samples were being irradiated in the unit at the time of the safety check and there were no exposures of personnel as a result of the failure, nor were any elevated radiation levels detected from the device. The device was subsequently locked out of service pending repair. The next day, the licensee obtained the necessary replacement part and repairs were affected by their trained technical staff according to the manufacturer's instructions.
"The licensee has contacted the authorized service vendor, Best Industries, to discuss the matter as well as the irradiator manufacturer, MDS Nordion. This device contains an IAEA Category I quantity of radioactive material (Co-60) in a permanently shielded configuration."

"On January 11, 2012 at 22:15 [EST], the High Pressure Coolant Injection System (HPCI) was declared inoperable due to a failure of the turbine governor valve to respond to demanded position. When demanded to travel to the full closed position, the governor valve remained full open rendering the speed and flow control system for the turbine inoperable. The failure was discovered as part of a planned maintenance evolution.
"All other Emergency Core Cooling Systems and the Reactor Core Isolation Cooling (RCIC) system remain operable. The unit remains at 100% power.
"The station has initiated an Event Response Team to identify and correct the cause of the failure. No personnel injuries resulted from the event.
"The NRC Resident Inspector [has been notified] and Lower Alloway Creek Township will be notified."
The unit is in a 14-day LCO for HPCI inoperability. |

"The following information is provided as a sixty (60) day telephone notification to the NRC in accordance with 50.73 (a)(1) in lieu of the submittal of a written LER to report a condition that resulted in an invalid actuation of general containment isolation signals affecting containment isolation valves in more than one system and emergency service water systems that normally do not run and that serve as ultimate heat sinks. NUREG-1022, Revision 2, identifies the information that needs to be reported as discussed below.
"On December 4, 2011, Clinton Power Station was in Mode 5 (Refueling) conducting refueling outage activities, including the installation of a self test system power supply modification. During post-maintenance activities associated with the affected power supplies, an unexpected voltage reading was identified. While investigating the anomaly, one of the two nuclear system protection system essential logic power supplies was de-energized with the redundant power supply not yet restored. At 0609 [CST], the power supply was re-energized, resulting in an inadvertent actuation of the logic.
"Containment isolation valves on the following systems automatically closed: Instrument Air, Service Air, and Containment Floor Drain. Additionally, the Division 1 Shutdown Service Water (SX) Pump started. These actuations were not valid since the actuations were associated with low reactor water level conditions (Level 1 and Level 2) which were non-existent at the time of the event. The associated actuations were successful had the actuations been valid.
"This event is reportable in accordance with 10CFR50.73 (a)(2)(iv)(A) and has been entered into the Corrective Action Program."
The licensee notified the NRC Resident Inspector. | |
