[Global] [EXTERNAL] FW: Quick question about underwater decon of walls and floors

[Coughlin, Joseph J: (Constellation Nuclear)]

At Braidwood we use a robot on the fuel travel path as well as vacuuming. Both go thru at trinuc and directly don't usually result in filter changes. Nothing as far as the walls..........Thx Joe

Have any of you used an underwater wall/floor scrubber to help with decon of you refuel cavity? If so, could you please share information or what kind of dose rates you had on the scrubbing pads and how often they needed to be changed out? We will be filtering through a Tri-Nuc system.

Thank you,
