| ENS 40693 | 21 April 2004 16:00:00 | 10 CFR 20.2202(b)(1) 10 CFR 36.83(a)(1) | Irradiator Source Rack Jammed in the Up Position | At 1200 EDT operators were lowering a source rack when it jammed due to a maintenance ladder. The licensee entered their emergency procedure and contacted the manufacturer, i.e., MDS Nordion, for assistance. MDS Nordion is expected onsite at 1040 EDT tomorrow 4/22 to help the licensee develop a recovery plan. The stuck source rack contains approximately 2,030 curies of Co-60. The maze is closed restricting personnel access. There were no personnel exposures associated with this occurrence. A conference call with the Baxter Plant Manager and NRC staff was established to discuss the details of this report.
The licensee reported that at 2000 on 04/23/04 the source was placed in the shielded position submerged in 25 ft of water in the pool. They are terminating this event. Notified Tom Decker, George Pangburn, Frank Costello, Cathy Modes, and Betsey Ullrich
The licensee reported that a re-enactment of the event indicates that two plant employees may have been over-exposed during the initial event. The licensee is conservatively reporting this update under 10 CFR 20.2202 (b)(1) since the exposure value is unknown but believed to be less than 5 rem. Personnel dosimetry is being analyzed and the calculations are being verified by the contractor at the site. The licensee will update this event when the exposure data is known. The licensee has informed the on site Regional Materials Inspector (Diaz). Notified NMSS (Fred Brown) and R1DO (Richard Barkley). |
