Darlington Refurbishment has just completed a major series to remove 960 feeders from Unit 2 on its refurbishment.
This work was performed by the Joint Venture (SNC Lavalin, AECON) with OPG support. The work was completed on schedule, and with zero personal contamination events. Overall dose collected was within budget. The feeders were packaged into waste containers and shipped off-site without incident. This result was made possible through a massive advance planning effort and field co-ordination effort.
The presentation includes video footage of the techniques used to protect workers from potential contamination uptakes. There are specific overpack containers designed and used specifically for this series. Worker hot hand-offs were successfully used to keep continuous vault work 24/7.
