SCROGGS HQ OPS Officer: STEVE SANDIN | Notification Date: 03/31/2008 Notification Time: 18:19 [ET] Event Date: 03/28/2008 Event Time: [PDT] Last Update Date: 04/18/2008 | Emergency Class: NON EMERGENCY 10 CFR Section: AGREEMENT STATE | Person (Organization): RYAN LANTZ (R4) KEITH McCONNELL (FSME) | Event Text AGREEMENT STATE REPORT INVOLVING A PARTIAL EQUIPMENT FAILURE OF AN HDR UNIT DURING A SOURCE EXCHANGE The following information was received from the State of Washington via email (quotations omitted for ease of reading): STATUS: New Licensee: Providence Everett Medical Center City and State: Everett, WA License Number: WN-M0135-1 Type of License: Medical Date and time of Event: 28 March 2008 Location of Event: Everett, WA ABSTRACT: (where, when, how, why; cause, contributing factors, corrective actions, consequences, Dept. of Health (DOH) on-site investigation; media attention): A Varian Medical Systems (varian) representative was attempting a routine source exchange at the licensee's facility. There were no patients or Medical Center staff involved in the source exchange process. The varian rep noted some trouble with making the "old" source enter the exchange container. After several attempts the rep realized the transfer was not proceeding as expected. The rep telephoned staff at Varian Corporate headquarters for assistance. The decision was made to cut the source wire near the source and place the source assembly into the emergency shielded source container (emergency pig). After the wire was snipped and the cut piece placed into the emergency pig, the rep performed a survey and noticed that the radiation levels were less than expected. At this time the licensee and the Varian rep both notified the Office of Radiation Protection of the event by telephone. The room was locked and barrier tape placed across the door. A Varian recovery team was called for and arrived at the Medical Center, with the source designer, on Saturday, 29 March 2008. An Office of Radiation Protection investigator also joined the team on Saturday to direct the onsite investigation and recovery. The investigation determined that both the dummy wire and the source wire had tried to exit the HDR unit simultaneously. The wires become stuck in the "home switch" part of the HDR. When a wire was cut it had been the dummy wire and not the source assembly wire. The cutoff dummy wire had been placed into the emergency pig which had given lower then the expected dose rate readings. On Saturday, the recovery team successfully retracted the source into the HDR. Testing is underway to determine why the HDR source exchange process had allowed both wires to be sent out at once. A comprehensive written report is expected from the manufacturer within the next few days. Notification Reporting Criteria: WAC 246-220-250 Equipment Failure. Isotope and Activity involved: HDR Sealed Source: Ir-192, approximately 185 GBq (5 Curies). Overexposures? (number of workers/members of the public; dose estimate; body part receiving dose; consequence): None Lost, Stolen or Damaged? (mfg., model, serial number): Varian HDR source model VS2000 (not lost, not stolen, possibly damaged). Disposition/recovery: Source recovered 29 March 2008 by Varian recovery team. Leak test? No "official" leak test yet but several contamination wipe surveys were performed during the course of the recovery. All of these were negative. Vehicle: 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; Varian VariSource Ix (Trademark) HDR Exposure (intended/actual); consequences: None to patients and the public. The highest exposure received by a recovery team member was 87 mRem. Was patient or responsible relative notified? N/A Was written report provided to patient? N/A Was referring physician notified? N/A Consultant used? No Event Report # WA-08-020. * * * UPDATE VIA E-MAIL FROM ARDEN SCROGGS TO JASON KOZAL ON 04/18/08 AT 1836 * * * "A written report was received [by the state] from the manufacturer. "The Varian report concluded the cause of the incident was 'the service engineer mistakenly extending the active source wire while the dummy wire was already in the same pathway. This action jammed the dummy and source wires at the home switch and prevented the active wire from properly retracting to the tungsten safe when commanded.' "[The manufacturer] also concluded the likelihood of a licensee / operator recreating this type of event was nil, since the conditions which allowed this to happen are only present when the factory service engineer is working on the unit. "This was originally reported as an equipment failure but now appears to be an error by the manufacturer's representative."

Customer reported item was not in ammo box upon receipt. Cardinal Health has searched premises with no indication. Procedures were reviewed and found to be correct. Corrective action consisted of a staff meeting to reiterate the requirement to follow proper procedure when packaging and shipping radioactive material. Incident referred to materials office for further investigation. This office will take no further action." FL Rpt No: FL08-056 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. 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.

Specifically, although it cannot yet be determined with certainty, it appears that a small depleted uranium pellet used as a detector source is missing. The radioactive source was one of several installed and used in Eberline, Model DA-1, gamma detectors to provide an indication of continuous operability. From the available documentation, it appears that the detectors were installed in 1993, well before Westinghouse acquired the facility in 2000. "If it is confirmed that the radioactive source indeed is missing and is of the type, quantity, and form of other similar detector sources present at the facility, the source is a depleted uranium pellet in a solid oxide form, with a total mass of approximately 5.5 grams. The total uranium mass of the source is approximately 4.85 grams. The uranium-235 (U-235) activity in the source is approximately 0.037 microcuries, which is a quantity greater than ten (10) times the 10 CFR 20, Appendix C, limit for U-235 of 0.001 microcuries. "For reasons discussed further below, the circumstances under which the apparent loss of licensed material may have occurred cannot be determined with certainty. With the facility in a decommissioning status, it is possible that the source was separated from its detector during decommissioning activities performed since the site ceased fuel fabrication activities in 2001. Subsequently, the probable disposition of the source may have been its having been packaged and shipped either as Special Nuclear Material inventory removed from the site or as radioactive waste. Either situation is credible since significant decommissioning activities in the site Process Buildings has involved the removal of remaining Special Nuclear Material inventory and contaminated process equipment. "As of the date of this report, immediate actions have included the following: "(1) Similar detector sources from gamma detectors that no longer are needed/used have been removed and properly stored. "(2) On April 7, 2008, a physical search and radiological surveys were conducted in an attempt to determine if the potentially missing radioactive source remains in the Process Building area. The source was not found. "(3) An investigation is ongoing to confirm whether the licensed material is indeed missing. This investigation includes searching through Radiation Protection records for additional information regarding the source and any potential evidence of its disposition. It is noted that the ongoing investigation is challenged by: (1) the subject source and similar radioactive sources have not been formally tracked within an inventory and tracking system; (2) a change in facility ownership in 2000; and (3) site management and staff turnover since decommissioning started, such that individuals who may have had first hand knowledge of the cause and/or disposition of the subject radioactive source are no longer at the facility. "The investigation into this event is continuing, and any further details will be provided in the written report that Westinghouse will submit within 30 days of this telephone report pursuant to 10 CFR 20.2201 (b)."
