| Event Text AGREEMENT STATE REPORT - DELIVERED DOSE DIFFERENT THAN PRESCRIBED DOSE
The following information was received by e-mail:
"The Director of Oncology Services at Decatur Memorial Hospital contacted the Agency [state] to give a preliminary notification of a medical event that happened in September 2006. Following the receipt of additional training by their oncologists regarding medical event criteria, they began to conduct a retrospective review of past prostate cancer treatments that have been performed at their facility since 2002. A particular case was readily notable when the comparison of dose intended vs. dose received was made. Using 81 I-125 seeds, the prescribed dose to the target (D100) was 132.5 Gray, the delivered dose was 32.5 Gray which is only 24.5 percent of the intended dose. However the review showed all seeds intended to be implanted were successfully placed under guided ultrasound and post operative x-ray imaging showed all seeds to be within the target volume. Subsequent follow-ups with the patient over the past 5 years have shown a significant reduction in PSA levels, no evidence of recurrent cancer and no adverse side effects to the bladder, rectum, urethra or other associated dysfunction for the now 87 year old patient. At the time of implant, there were no notes in the surgical file to suggest a change in shape or size of the prostate which would suggest pre-treatment planning performed was invalid. Routine CT imaging conducted at 30 days post treatment as part of the follow-up process showed the prostate had expected swelling present. When dosimetry calculations were performed using the increase in volume, the total delivered dose value for the intended treatment site fell, resulting in the criteria for a medical event being met. The attending oncologist does not intend to notify the patient of this recent discovery. The doctor believes that such a notification would be against his medical judgment and would do unnecessary harm to the patient in this instance considering the success of the treatment.
"The responsible oncologists and the rest of the treatment team were interviewed by the [Illinois Emergency Management] Agency yesterday afternoon regarding additional details of this event and planned actions. The team indicated that [they] would continue review of the 240 cases but didn't believe that any changes to its current program were warranted at this time based on this one observation. Anecdotally, none of the physicians could remember any of their patients having adverse or unexpected effects during subsequent follow-ups. Nor had any [patients] required additional or supplemental treatment of any kind (i.e. hormonal, surgery, external beam, additional seeds) for recurrent cancer. [The team] couldn't rule out that a similar medical event requiring reporting wouldn't be discovered as they continued their review."
Illinois Event: IL11053
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 - OPERATING MECHANISM FAILED ON GAUGE
The following information was obtained from the State of Texas via email:
"On May 12, 2011, the Agency [state] was notified that the operating mechanism on an Ohmart Model SHLM-BR-2 nuclear gauge containing 1,000 milliCuries of Cesium (Cs) 137 had failed. The operating mechanism consists of two rods. The source is mounted on one rod and the other rod is used to move the source into and out of the source holder. The pin used to connect the two rods together broke so the source can not be manipulated. The source is currently located inside the vessel in its normal operating position. There is no increased risk of radiation exposure to any individual. The licensee is making arrangements to have the gauge repaired. The cause for the failure is still being investigated. Additional information will be provided as it is received in accordance with SA-300."

The following information from the State was received by email:
"On May 12, 2011, the Agency [Texas Department of Health] was notified by the licensee that the shutter on a Ohmart/Vega Model BAL nuclear gauge containing 100 milliCuries of Strontium (Sr) - 90 was stuck in the closed position. The gauge has an electronic shutter, which is not functioning. The licensee contacted their service provider for assistance in repairing the gauge. The cause for the failure is being investigated. Additional information will be provided as it is received in accordance with SA-300."

The following information from the State was received by email:
"On May 12, 2011, the Agency [Texas Department of Health] was notified by the licensee that on April 18, 2011, while conducting a routine inspection of a NDC model 8000 TDI nuclear gauge containing 80 milliCuries of Americium (Am) - 241 they found the shutter for the device was missing. The licensee conducted a search for the shutter, but it was not found. The licensee contacted the manufacturer for assistance in repairing the gauge. The licensee placed a lead plate over the shutter to prevent exposure to personnel. The gauge was repaired by the manufacturer on April 29, 2011. Additional information will be provided as it is received in accordance with SA-300."

The following information from the State was received by email:
"On May 12, 2011, the Agency [Texas Department of Health] was notified by the licensee that while performing a routine inspection of a Ohmart/Vega model SH-F2 nuclear gauge containing 200 milliCuries of Cesium (Cs) - 137 they found the shutter for the device stuck in the open position. The licensee believes the probable cause for the event is a buildup of debris in the operating mechanism of the gauge. The gauge is used for level detection on a vent stack in an area of the plant not routinely occupied. The licensee is lubricating and trying to cycle the shutter frequently. The licensee has contacted a service provider to assist them if needed. No exposure to any personnel has occurred due to this event. Additional information will be provided as it is received in accordance with SA-300."

The following information was received by e-mail:
"Empty [Model] LR-230 shipping containers received from off-site where one (1) LR-230 had removable surface contamination above limits for alpha/beta activity on the outer surface of the container (~7,800 dpm/100 sq cm alpha and 13,300 dpm/100 sq cm beta). The LR-230 shipping containers are used to transport uranyl nitrate (<5.0 wt % U-235). Contamination was not related to container integrity. Contamination appears to be related to minor drips during unloading. Areas have been successfully decontaminated.
"There were no actual or potential safety consequences to workers, the public, or the environment."

"At 0954 [PDT] on May 17, 2011, Unit 1 startup power was lost following actuation of the 230 kV line pilot wire differential relay 287X. Loss of power to the Unit 1 12 kV startup bus produced a startup undervoltage signal that caused all Unit 1 emergency diesel generators (EDGs) to start in a standby mode. The EDGs started as designed with no problems observed. No vital loads were affected as a result of the 12 kV bus loss and subsequent undervoltage. Actuation of differential relay 287X was due to maintenance activities on the safeguard relay board where differential relay 287X is installed.
"At 1056 on May 17, 2011, the Unit 112 kV startup power system was made available to supply power to the 4 kV vital buses. All Unit 1 EDGs were shutdown and returned to their normal at-power standby configuration, and differential relay 287X [was] reset.
"Unit 2 was unaffected by this event.
"The NRC Resident Inspector has been notified." |

"On 5/17/2011, at 1404 CDT, Dresden Operations was notified by a Mechanical Maintenance Supervisor that both intake bay 13 stop logs were mistakenly installed during routine bay cleaning on 5/17/2011 at 1030. Installation of both bay 13 stop logs removes the suction source for the Containment Cooling Service Water (CCSW) system and renders the CCSW systems inoperable for both Dresden Units 2 and 3. Appropriate Technical Specification Required Actions were entered which direct restoration of at least one train of CCSW within 8 hours on each unit. Mechanical Maintenance was directed to remove the stop logs from Bay 13. At 1410 stop logs were removed and CCSW was declared operable for both Unit 2 and Unit 3. This event is reportable under 10 CFR 50.72 (b) (3) (v) an "Event or Condition That Could Have Prevented Fulfillment of a Safety Function."
