| This material event contains a "Category 2 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - LOST AND RECOVERED RADIOGRAPHY CAMERA
The following was received from the State of Oklahoma via email:
"Hi-Tech Testing Service, an Oklahoma industrial radiography licensee based in Mustang, Oklahoma, reports that they temporarily lost custody of an industrial radiography camera containing an iridium source. At about 1:40 PM today, the Hi-Tech RSO reported by phone to DEQ [Department of Environmental Quality] that while doing radiography overnight at a compressor station near Perkins, Oklahoma, radiographers unintentionally left the radiography camera (with source inside) at the site. The error was discovered this morning when an inspector from Hi-Tech's client found the camera at the site. The client contacted Hi-Tech, who recovered the camera and have it in their possession. They report no evidence that the camera was tampered with or that there was an overexposure involved. DEQ will do an investigation of the incident.
"The above is very preliminary, based on phone reports from the licensee. It is basically all the information known to DEQ at this time. It will be updated as more information becomes available."
THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL
Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

| Event Text PART 21 - MILLER AIR CYLINDER SEALS DEDICATION ISSUE
The following was received from the licensee via fax:
"This is to notify the US Nuclear Regulatory Commission that, in accordance with the provisions of 10 CFR Part 21, we have identified a potential issue and are submitting our evaluation of the event.
"Description: Flowserve supplied a quantity of two Size 6 Class 900 Anchor Darling Double Disc gate valves with tag numbers CV-3027 and CV-3056 to Palisades Nuclear Plant in 2007. The valves are actuated by Miller air cylinders and have a safety function to maintain the system pressure boundary by remaining fully open during injection and to subsequently move to the fully closed position upon receipt of a recirculation actuation signal. This Miller air cylinder is not spring-assisted and thus uses air to perform the safety-related function. As such, the air cylinder, any tubing, and seals associated with the air system would also be considered safety related. When the valve was tested prior to shipment, the actuator was dedicated as an assembly and performed adequately. However, the seals containing the air system in the Miller Air Cylinder and Flow Control valve were not individually dedicated as a basic component - that is, the seal material was not verified. There is no indication that the material is defective, but in addition to the functional testing at the Flowserve facility, the material of the seals should have been checked and verified. The Flow Control Valve was ordered with Nitrile (Buna-N) seals while the Air Cylinder was ordered with Viton seals. While the seal materials were not verified, the only possible seal material for these items would have been Viton, Buna-N, or EPR.
"Scope: Flowserve has performed a review of all other air cylinders provided from the Raleigh facility over the last 12 years and found no other instances of this issue. Therefore, the scope of this notification is limited to only the two tag numbers 01-3027 and CV-3056 at Palisades Nuclear Plant.
"Proposed Action: Flowserve will provide safety-related replacement seal kits for all seals containing the air system for the CV-3027 and CV-3056 valves. This will be sent on a zero dollar purchase order to Palisades Nuclear plant and will be completed as soon as Flowserve receives the purchase order." | |
