| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text INDUSTRIAL GAUGE INOPERABLE DUE TO BENT SHUTTER
"On May 21, 2012, the shutter on an industrial thickness gauging device (NDC Infrared Systems model 102) was discovered to be bent so that when closed, it did not adequately attenuate the radiation beam from the device. The facility Radiation Safety Officer removed the gauging device from the production line and secured plate steel over the radiation source to provide supplemental shielding to the same degree as the undamaged shutter. The device was placed in secure storage pending shipment for repair.
"The device was shipped to 3M Corporate Health Physics in St. Paul, MN, on May 25, 2012. On May 29, 2012, the device was received and the shutter assembly replaced with an undamaged, spare shutter assembly. The repair was performed by [corporate radiation safety staff] under US NRC Radioactive Materials license no. 22-00057-03. The device was then returned to 3M Springfield.
"Conversations between 3M Corporate Health Physics and US NRC Region III (Geoffrey Warren) on May 29, 2012, indicated that this event is reportable under 10 CFR 30.50(b)(2).
"Location of event: 3M Springfield, 3211 East Chestnut Expressway, Springfield, MO 65802
"Isotope, quantity, chemical and physical form: Am-241, 150 milliCuries on February, 7, 1997, double encapsulated solid source (special form).
"The event resulted in no additional exposure to any individual."
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

"At approximately 5:02 a.m. CDT on June 5, 2012, during scheduled test of the Technical Support Center (TSC) ventilation system, it was determined that the system would not function in the emergency mode. The plant is currently in cold shutdown for a maintenance outage.
"The activity was terminated and the TSC ventilation system was restored to its normal configuration. This failure caused the TSC to be potentially uninhabitable, and thus it could not have been relied upon for the purposes of the site Emergency Plan. Repairs and retest of the system were successfully completed at approximately 11:30 a.m. CDT.
"This condition is being reported in accordance with 10CFR50.72(b)(3)(xiii) as an event that resulted in a major loss of emergency assessment capability. The NRC Resident Inspector has been notified."
The suction damper to the filter train failed to open which led the licensee to declare the filter train inoperable. |

"On June 6, 2012, at 0045 EDT hours and the reactor at 100% core thermal power the following press release being issued by Entergy Nuclear regarding the status of the ongoing labor negotiations.
"Plymouth, Mass. - Entergy Nuclear, the company that owns and operates the Pilgrim Nuclear Power Station is
implementing a contingency staffing plan after weeks of negotiations between the Company and the Utility Workers Union of America Local 369 leadership were unsuccessful in reaching an agreement for a new union contract.
"Local 369 has stated flatly that while its members are not on strike, they reserve the right to walk off the job at any time, without any notice, and leave the nuclear power plant critically understaffed and in violation of the plant's operating license. This disregard for public safety is unacceptable. Accordingly, the company's contingency plan is being implemented.
"The contingency plan for temporary alternate staffing is consistent with Nuclear Regulatory Commission regulations and is in the interest of safety and maintaining formal organizational controls on the plant site. Highly qualified individuals from within Pilgrim's management team as well as the Entergy nuclear fleet will be filling the necessary positions.
"The NRC Resident Inspector staff has been informed of this press release and notification.
"This notification is being made in accordance with 10 CFR 50.72(b)(2)(xi)."
The licensee will be notifying the Massachusetts Emergency Management Agency. |

"Wolf Creek commenced a nuclear plant shutdown in accordance with Technical Specifications. Engineering analysis has determined that with one non-functional Class IE A/C unit, there is inadequate cooling available to support electrical power systems required by Technical Specifications (TS) 3.8.4, 3.8.7, 3.8.9, during all postulated conditions. Actions are currently underway to restore the non-functional Class IE A/C unit to a functional status."
The non-functional Class IE A/C unit had a clogged oil pump strainer. Per TS 3.0.3, Wolf Creek began reducing power and was at 89% power at the time of the report.
The licensee has notified the NRC Resident Inspector. | |
