| Event Text PART-21 NOTIFICATION - UNQUALIFIED MATERIAL USED IN ELECTRICAL PENETRATION ASSEMBLIES
The following information was received via fax:
"Material supplied to MTCN [Mirion Technologies (Conax Nuclear)] by approved sub-suppliers audited to NCA-3800 by MTCN was considered to be ASME [American Society of Mechanical Engineers] qualified source material for Section II and Section III requirements. During triennial survey of MTCN by the ASME for renewal of our N Type Certificates of Authorization, it was identified by the ASME survey team that material supplied by two (2) MTCN approved sub-suppliers should be considered unqualified source material. At that time, MTCN's Quality Program did not include the use of unqualified source material.
"Testing of the coupons for materials used with the basic components supplied to the operating plants is expected to be completed within the next 30 days."
The potentially defective components are electrical penetration headerplates, mounting weldment rings and weld neck flanges for mounting the electrical penetration assemblies.
The affected facilities are: Oconee, Ginna, Crystal River, Point Beach, Monticello, Cook, and Turkey Point.
Point of contact: John MacDonald 716-681-1973
* * * UPDATE FROM JOHN MACDONALD TO HOWIE CROUCH ON 9/23/13 AT 1747 EDT * * *
MTCN has determined the material supplied to U.S. plants does not impact the material safety or performance of the EPAs (Electrical Penetration Assemblies) delivered. Chemical and mechanical re-verification test results to date indicate there have been no test failures compared to the ASME SA-240 material requirements.

"On September 16, 2013, the Agency [Texas Department of Health] received notification from the licensee that on September 12, 2013, one of its radiography crews working at a temporary work site in Tilden, Texas, had been unable to retract an Iridium-192 source back into its SPEC 150 exposure device. After several attempts, the connector on the end of the cable came off which allowed the cable to come all the way through the device and left the source inside the guide tube.
"Source retrieval was performed by authorized person who received 120 millirem, an assistant who received 55 millirem, the radiographer trainer who also assisted received 100 millirem (including the day's work) and the radiographer trainee who received 32 millirem (including the day's work).
"The licensee will have the crank assembly, cable, and connector evaluated. No member of the public received any radiation exposure as a result of this event. An investigation into this event is ongoing. More information will be provided as it is obtained in accordance with SA-300."

"On September 16, 2013, the licensee notified the Agency [Texas Department of Health] that on September 13, 2013, one of its radiography crews had been unable to retract a Iridium-192 source back into a SPEC 150 exposure device at a temporary work site in Tilden, Texas. Following the first exposure of the morning, the source pigtail would not retract fully into the device. An authorized person performed the source retrieval. This individual received 20 millirem and the individual that assisted him received 10 millirem. No member of the public received any exposure as a result of this event.
"The licensee's radiation safety officer inspected the inside of the source guide tube using a tube scope and found that the coil in the source guide tube was pushed out into the inside of the tube where the connector fitting was crimped onto the guide tube. The connector had just been replaced by a local service company. An investigation into this event is ongoing. Information will be provided as it is obtained in accordance with SA-300."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text LOST BRACHYTHERAPY MEDICAL SOURCE
The licensee reported that a brachytherapy source/seed was lost after completion of a medical procedure. After the seed was removed from the patient, the device was improperly placed in the rack for sterilization and cleaning and it is believed the seed was lost as part of this cleaning process. Normally, the device would have been placed in a surgical bowl and moved to a flash chamber for seed recovery. The seed was a Best Double Walled I-125 seed with a 204 microcurie source, model #2301.
There was no harm to the patient or exposures to other personnel. The licensee is continuing their investigation and will provide additional information when it becomes available.
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.

"On 09/22/2013 at 1940 CDT, Prairie Island Nuclear Generating Plant (PINGP) requested an offsite ambulance via the 911 system for medical assistance for an individual in the radiologically controlled area. The person was treated as potentially contaminated because a complete survey to confirm the absence of contamination was not completed prior to transport of the individual. An ambulance arrived on site at 1956 CDT and departed the site at 2036 CDT to the Red Wing Minnesota Hospital. PINGP radiation protection personnel accompanied the individual to the hospital. A survey at the hospital determined that the individual was not contaminated.
"This is considered a transport of a potentially contaminated individual requiring an 8 hour ENS Notification per 10CFR50.72(b)(3)(xii).
"The Prairie Island Indian Community was notified of the transport of an individual by ambulance.
"This is considered a notification of another government agency and an event that may have potential interest to the media requiring a 4 hour ENS Notification per 10CFR50.72(b)(2)(xi).
"The licensee notified the NRC Resident Inspector." |

"Ventilation process radiation monitors for the Turbine Building Stack Discharge (monitors HVR*RE10A and HVR*RE10B) will be out of service for preplanned maintenance. This is reportable in accordance with 10 CFR 50.72(b)(3)(xiii)."
The licensee stated that this condition is being reported based on the inability to sufficiently identify and classify an Emergency Action Level for radiation releases that utilize input from the affected monitors while they are out of service.
The licensee will notify state and local authorities. The licensee will also notify the NRC Resident Inspector. |

"At 1340 CDT, on 09/23/2013, as part of a vendor analysis for the high energy line break reconstitution project, it was determined that Room 81 and 82 epoxy floor coatings do not meet the design basis requirements for a high energy line break barrier. This is an unanalyzed condition based on 10 CFR 50.72(b)(3) as loss of the floor coating could affect multiple redundant trains of safety-related equipment during a design basis event. The plant is currently in a cold shutdown condition."
The licensee has notified the NRC Resident Inspector. |

"At 16:55:59 [CDT] on September 23, 2013, indication was received in the Control Room that two Secondary Containment doors, in one access opening, were opened simultaneously. The interlock mechanism preventing both doors from operating simultaneously did not operate as expected. This condition represents a failure to meet Surveillance Requirement 3.6.4.1.2. As a result, entry into Technical Specifications 3.6.4.1 condition A was made due to Secondary Containment being inoperable. The doors were secured at 16:56:04 and Secondary Containment was declared operable. This event is being reported in accordance with 10 CFR 50.72(b)(3)(v)(C) as a condition that could have prevented the fulfillment of a safety function.
