Event Notification Report for February 17, 2014

AGREEMENT STATE REPORT - POSSIBLE DISCONNECT OF INDUSTRIAL RADIOGRAPHY EQUIPMENT SOURCE

The following information was provided by the State of Kansas via email:

Industrial radiography equipment failed to function as designed which resulted in a possible source disconnect. The radiography equipment was located at a work site in Winfield, Kansas. The radiography equipment contained a 56 Curie Ir-192 source. The State of Kansas will update the event as more information becomes available.

Kansas Item Number: KS140003

LOSS OF SECONDARY CONTAINMENT DIFFERENTIAL PRESSURE

"Reactor Building (Secondary Containment) pressure rose above the Technical Specification Surveillance requirement of 0.25 inches vacuum water gauge multiple times from 0044 [PST] to 0305 [PST] on 2/17/14. The alarm was received in the control room at 0305 [PST]. This is reportable as an event that could have prevented fulfillment of a safety function needed to control the release of radiation and mitigate the consequences of an accident. Reactor Building pressure has been restored to normal (greater than 0.25 inches of vacuum water gauge), returning Secondary Containment to operable status. Highest actual value indicated was +0.21 inches pressure water gauge. The cause of the event is under investigation.

"There were no radiological releases associated with the event.

"The NRC Resident Inspector has been notified."

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN

The following information was received from the State of Colorado via email:

"Detail: After no response from initial mailing to Fort Collins South Sanitation District [from the Colorado Department of Public Health and Environment (CDPHE)] , a call was made to verify information from SRB Technologies quarterly report on 10-21-2015. The superintendent of the facility was unaware of the order for the exit signs and had not received the annual mailing from our office. He was emailed a copy of the manufactures report and annual forms to be completed and asked to verify if the exit signs had been installed at the location reported. The superintendent stated a project was being constructed during the time the signs were ordered however, he would have to contact the companies involved with the project. He contacted the local distributor, CED, 2405 W 15th Avenue, Denver, CO 80204. CED stated they delivered the signs to the electrical contractor on 2-7-14. The superintendent then contacted the electrical contractor Master Electrical Contractors Inc. [MECI] for further information. The superintendent emailed our [CDPHE] office on 11-18-15 regarding the tracking events for the exit signs and provided a report from MECI. The lost exit sign is model number BX-20-WH, serial number is C107403, with activity of 20 Ci of Tritium H-3 shipped from SRB Technologies on 1-24-14 for installation at 2560 East County Road 32, Fort Collins, CO 80528.

"Event description: During construction of the dewatering and headworks improvement project, one of the five tritium exit signs was lost. The signs were in the possession of Master Electrical Contractors at the site. It is not certain at what point during the project or what caused the one sign to be lost or where it ended up. Therefore, the General Contractors of the project, Filanc Construction and Master Electrical Contractors, shall be responsible for the lost sign."

Colorado Event Report ID No.: CO15-I15-32

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.

PART 21 - BEARING DEFECT

The following was received via email:

"On Dresser-Rand Drawing 75439A part number 07 is identified as a Heim LSS-8 bearing that has an Aluminum Bronze insert to accommodate a non-lubricated application. Dresser-Rand shipped 10 bearings part number 75439A07 to Dominion Nuclear in 2006 that were Seal Master Com 8 bearings that do not have an Aluminum Bronze insert.

"This bearing is used on turbines that have a PG type mechanical governor with the cam plate linkage. Extended operation without lubrication will result in the Seal Master Com 8 bearing seizing. The customer should visually inspect this bearing for the bronze insert. If no insert is visible then the bearing should be replaced at the first opportunity."
