The licensee received 125 millicuries of Krypton-85 in a cylinder that was in excess of their license limit. The license limit is 5 millicuries. During an experiment to transfer the Krypton-85 to an evacuation chamber, the chamber did not pressurize as expected, and all 125 millicuries of Krypton-85 was evacuated to atmosphere. The licensee is still investigating the incident and will provide additional information when it becomes available.

| Event Text AGREEMENT STATE REPORT - UNABLE TO RETRACT RADIOGRAPHY CAMERA SOURCE
The following information was obtained from the State of Arkansas via email:
"Mistras Group, Inc., ARK-1034-03310, reported the inability to retract a 2.738 TBq (74 Ci) Ir-192 source (Source QSA Global Model A424-9, Serial 10270G) into the radiography exposure device (QSA Global, Model 880 Delta, Serial D9086) on 9/24/2014.
"During the morning of September 24, 2014, the radiographer's written statements indicated that a piece of pipe shifted and rolled onto the guide tube during an exposure. This action caused a crimp in the guide tube and the source was not retractable.
"The radiography crew reset the boundaries to 2.0 mR/hr and contacted the home office. The RSO of the Baton Rouge, Louisiana office responded to the site.
"The RSO reported that upon arrival, the radiography crew had reset the boundaries to 2.0 mR/hr. The source was located in the collimator and the crimp location was 6 inches from the collimator. The RSO placed 50 pounds of lead shot over the collimator and placed a metal plate under the crimp. The RSO then used a hammer to 'round out' the guide tube allowing the source to be retracted into the camera. The guide tube was removed from service and the crank-out was inspected for any damage.
"The RSO stated that he wore an SRD [self-reading dosimeter] with a 0-200 mR range and this was found to be off-scale. The RSO was instructed by the State to submit the dosimetry badge for immediate processing.
"The pocket dosimeters for the radiography crew were reported to read 1 mR and 0 mR respectively.
"No other survey readings, other than the 2 mR/hr boundary, have been reported.
"The State is tracking this event under Arkansas Event Number AR-2014-007 and is continuing to investigate this incident." |

The following information was obtained from the State of Texas via email:
"On October 1, 2014, the Agency [Texas Department of State Health Services] received notice that on September 30, 2014, a radiography source disconnect had occurred at a temporary field site in east Houston. The camera was a Sentinel 880D (s/n D6746) with 68.3 curies of selenium-75 (s/n SE3877). The port cover had not been opened and the source had not been connected to the drive cable. Upon crank-out, the source was stopped at the port cover and could not be retracted. Retrieval was done by pushing the source back in via another drive cable from the other side. The person doing the retrieval received 38 mR to the body and 98 mR to the hand according to pocket dosimeters.
"Additional information will be provided as it is received in accordance with SA-300."

"This notification is being made as a result of notifications to other government agencies. A sodium hypochlorite leak occurred on site at Limerick Generating station on 10/7/14, that had the potential to enter the environment. The leak has been isolated. A flow control valve in the U1 cooling tower chemical treatment system caused the leak. The sodium hypochlorite that leaked was deposited into the onsite Holding Pond. The Holding Pond was being discharged at the time of the leak in accordance with procedures to support normal plant operations. The leak was discovered at 2110 hours [EDT on 10/7/14] and isolated at 2115 hours. The Holding Pond discharge was secured at 2125 hours. Sampling of the Holding Pond confirmed the presence of sodium hypochlorite. Since the Holding Pond was being released at the time of the leak, there is a potential that greater than 67 gallons of sodium hypochlorite could have been released to the Schuylkill River. This report is being made due to the potential that a reportable quantity of sodium hypochlorite could have discharged to the Schuylkill River while the Holding Pond was releasing during the sodium hypochlorite leak. Evaluations are being performed to quantify this actual volume of sodium hypochlorite that was discharged as a result of the leak."
The licensee has notified the NRC Resident Inspector and state and local authorities. |

"INPO-IER-L4-14-33 (Direct Current Circuits Challenge Appendix R Fire Analysis) was reviewed to determine applicability to ANO Unit 1 & 2. It was determined that 2P-21, Turbine Generator Emergency Seal Oil Pump, control cables are not fused and are routed through multiple fire zones containing safe shutdown equipment. A potential fire induced cable failure in any of these fire zones could result in a secondary fire or damage adjacent cables along the path of the unprotected cable. The concern is that under fire safe shutdown conditions, it is postulated that a fire in one zone can cause short circuits potentially resulting in secondary fires or cable failures in other fire zones where the cables are routed. The secondary fires or cable failures are outside the assumptions of the 10 CFR 50 Appendix R Safe Shutdown Analysis.
"This condition is reportable as an 8-hour ENS report in accordance with 10 CFR 50.72(b)(3)(ii)(B) as an unanalyzed condition. Compensatory measures (fire watches) have been implemented for affected zones of the plant.
"The NRC Resident Inspector has been notified." |

"This is a non-emergency notification.
"At approximately 10:40 AM on October 8, 2014, with the Harris Nuclear Plant operating at 100% power, a condition was discovered where a potential leak from a pipe supplying water to the fire suppression system in the diesel fuel oil storage tank building could result in damage to equipment in both trains of the onsite electrical power system.
"Neither the leak from the piping nor the damage to equipment actually occurred, so there are no actual safety consequences and no impact to public health and safety or the environment due to this condition.
"The condition was discovered during a Harris staff evaluation in the corrective action program. The condition will be fully investigated, including the extent of condition, and corrective actions taken to resolve the issue. Compensatory actions have been taken as interim actions to ensure safety systems are not impacted by the potential pipe leak.
"This event is reportable per 10 CFR 50.72(b)(3)(v).
"The NRC Resident Inspector has been notified." | |
