City and State: Tacoma, Washington License Number: WN-I014-1 Type of License: Fixed Gauge Date of Event: 31 December 2003 (when discovered by licensee Location of Event: 801 Portland Avenue, Tacoma, Washington ABSTRACT: (where, when, how, why; cause, contributing factors, corrective actions, consequences, Dept. of Health (department) on-site investigation; media attention): The licensed Radiation Safety Officer reported to the Department, on 31 December, he noticed that process fluids had eroded a � inch by 4 inch hole through the � inch thick gauge body where it attached to process piping. The damage was apparently confined to the device's body and the event is not considered to present an emergency at this time. The device had been in service for about 12 years and had reached the end of its useful service life. It was being removed to prepare it for disposal. The device is a Texas Nuclear Corp. Model 5176, Serial Number 2253, containing 7.4 gigabecquerels (200 millicuries) of Cesium 137. The licensee informed the department they would bolt a � inch metal plate to the device's attachment point, over the damaged area, to temporarily return the device to its normal level of shielding and integrity. After removal and the temporary repair, the licensee placed the device into secured storage, along with several other similar devices, in preparation for source removal and disposal in January 2004, by a service provider. The RSO, approved for device installation, relocation, removal from service, and surveys, reported that the device was reading 1.5 Mr/hr, contact at the damaged area, prior to the temporary repair. A similar, but undamaged, device read 1.2 Mr/hr at the same location. The RSO reported no activity from a wipe survey on the damaged device. The Department will perform an on-site investigation on 6 January 2004. No media attention has been attracted, yet. Notification Reporting Criteria: 10 CFR 31, General Domestic Licenses for Byproduct Material (damage to shielding) Isotope and Activity involved: Cesium 137, 7.4 gigabecquerels (200 millicuries) Overexposures?

The following information was received via email: This is an updated notification of an event in Washington State, reported to and investigated by, the WA Department of Health, Office of Radiation Protection. STATUS: update Licensee: Simpson Tacoma Kraft, LLC City and State: Tacoma, Washington License Number: WN-I014-1 Type of License: Fixed Gauge Date of Event: 31 December 2003 (when discovered by licensee) Location of Event: 801 Portland Avenue, Tacoma, Washington ABSTRACT: (where, when, how, why; cause, contributing factors, corrective actions, consequences, Dept. of Health (department) on-site investigation; media attention): The licensed Radiation Safety Officer reported to the Department, on 31 December, that he had discovered that process fluids (green liquor [sodium sulfite]) had eroded a 3-inch by 6-inch hole through a 1/8 inch thick aluminum gauge cover-plate on the gauge where the gauge attached to process piping. The damage was confined to the device's cover-plate and the event was not considered an emergency. The device had been in service for about 30 years and had reached the end of its useful service life. It was being removed in preparation for disposal. The device is a Texas Nuclear Corp., Model 5176, Serial Number 2253, containing 7.4 gigabecquerels (200 millicuries) of Cesium 137. The licensee informed the department they would bolt a � inch thick metal plate to the device's attachment point, over the damaged area, to cover the whole. After removal and temporary repair, the licensee placed the device into secured storage, along with several other similar devices, in preparation for source removal and disposal. A service provider, is scheduled to remove the devices from the licensee's facility in about April, 2004. The RSO, approved for device installation, relocation, removal from service, and surveys, reported that the device was reading 1.5 Mr/hr, contact at the damaged area, prior to the temporary repair. A similar, but undamaged device, read 1.2 Mr/hr at the same point. A Ludlum Model 3, SN 104500, calibrated 19 November 2003, was used for stated measurements. The RSO took a leak test inside the opened area. The RSO sent the leak test sample for analysis and subsequently reported the test indicated less then detectable activity. The Department performed an on-site investigation on 9 January 2004, resulting in this updated report. No media attention has been attracted, yet. Initial Notification Reporting Criteria was: 10 CFR 31, General Domestic Licenses for Byproduct Material (damage to shielding) but now we understand that shielding was not compromised. Isotope and Activity involved: Cesium 137, 7.4 gigabecquerels (200 millicuries) Overexposures? (number of workers/members of the public; dose estimate; body part receiving dose; consequence): N/A Lost, Stolen or Damaged? (mfg., model, serial number): damage confined to device cover-plate, of a Texas Nuclear Corp, Model 5176 device, Serial Number 2253 Disposition/recovery: removed from service, temporarily repaired, secured for pending disposal Leak test? Wipe survey indicated no contamination, leak test was negative Vehicle: (description; placards; Shipper; package type; Pkg. ID number) N/A Release of activity? None Activity and pharmaceutical compound intended: N/A Misadministered activity and/or compound received: N/A Device (HDR, etc.) Mfg., Model; computer program: See above Exposure (intended/actual); consequences: N/A Was patient or responsible relative notified? N/A Was written report provided? Pending Was referring physician notified? N/A Consultant used? N/A for this event Notified R4DO (Jeffery Clark), NMSS (Thomas Essig)
The changes include: 1. Update in status as complete, 2 Full description of the corrosive process fluids, 3. Additional information on the area of gauge that was damaged. This incident is considered closed as of January 27, 2004. This is an updated notification of an event in Washington State, reported to and investigated by, the WA Department of Health, Office of Radiation Protection.

The damage was confined to the device's cover-plate and the event was not considered an emergency. A service provider subsequently reported to the licensee, the plate is to prevent contaminants from fouling the shutter mechanism. The plate has little impact on shielding.
