The patient's prescribed dose was 144 gray to the prostate with a 12% exposure to the bladder. The procedure to the prostate was completed with extra I-125 seeds and the estimated dose to the bladder is 18%. It is believed that shadowing from the urethra, during treatment, was the cause. An attempt to withdraw the seeds from the bladder when the problem was identified was unsuccessful. The patient has been informed and the patient's physician will be informed and will consult with the urologist as soon as possible to determine a method for seed retrieval. * * * UPDATE ON 11/8/13 AT 1150 EST FROM STEPHEN SLACK TO DONG PARK * * * The following was received via email: "The event took place during an implant of I-125 seeds into the prostate of a patient. One strand of six seeds was instead implanted into the bladder. Attempts to remove the strand of seeds at that time were unsuccessful. "Renewed attempts were made to remove the strand this morning and they were successful. The implant was planned for 144 Gy to the prostate over the full decay time of the I-125. This would have resulted in a mean dose to the bladder of 22.34 Gy. If the extra seeds had remained in place, the mean dose to the bladder would have been 39.15 Gy; hence the report of a Medical Event. "By removing the seeds this morning, the mean dose to the prostate has been reduced to 23.09 Gy. This is more than 50 rads to the organ but less than a 50% increase over what the organ would have gotten in the planned treatment." Notified R3DO (Riemer) and FSME Events Resource via email. 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: 49528 | Facility: SAINT LUCIE Region: 2 State: FL Unit: [1] [ ] [ ] RX Type: [1] CE,[2] CE NRC Notified By: JOE HESSLING HQ OPS Officer: JEFF ROTTON | Notification Date: 11/12/2013 Notification Time: 01:23 [ET] Event Date: 11/12/2013 Event Time: 00:02 [EST] Last Update Date: 11/12/2013 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(2)(iv)(B) - RPS ACTUATION - CRITICAL | Person (Organization): ALAN BLAMEY (R2DO) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | M/R | Y | 90 | Power Operation | 0 | Hot Standby | Event Text MANUAL REACTOR TRIP DUE TO UNISOLABLE LEAK IN DIGITAL ELECTRO-HYDRAULIC SYSTEM "At 0002 EST, Unit 1 Manually tripped the Reactor from 90% power due to an unisolable leak in the Digital Electro-Hydraulic [DEH] System. All CEAs fully inserted into the Reactor Core. All systems responded as expected on the trip. Decay Heat removal currently using Main Feedwater and Steam Bypass Control System. After the trip, DEH pumps were secured to stop the transfer of fluid from the DEH system to the Turbine Building. Investigation ongoing to determine exact location of the leak. This condition is reportable pursuant to 10CFR50.72(b)(2)(iv)(B)." The was no impact on Unit 2. The NRC Resident Inspector has been notified. | |
