Braidwood uses Purolite Ortho-porous (NWR 5070P) resins in SFP. Have been using for about 3 years. Prior we used Purolite NWR501P Macro-Porous resin. We switched because of higher friability values. Dose rates (Non-Outage) on bridge are 0.14 - 0.27 mrem/hr. Prior to starting specialty resin use dose rates were 1 - 3 mrem/hr.
We also have tri-nuke with 0.1 micron absolute rated filters in the pool. Pre/post SF demin filtration we use 1 micron filter but are looking at going down to 0.05 micron.
