Do you have clarity issues with your SFP; what is the perceived cause? Only sometimes
Do you use supplemental filtration (such as Tri-Nuc filters) to maintain clarity? Yes, we have a 250 gpm in the pool. Only in-service when necessary
What permanently installed equipment do you use to maintain clarity? Our normal SFP cooling system is 2 pumps with 1 running (each 250 GPM) 1 heat exchanger, a resin bed and filter. We run 2 pumps occasionally to cool the pool before CCW outages.

R.E. Ginna is working to improve our SFP clarity. Currently, we have a large amount of "dirt" in our pool which causes the pool to cloud after 6-10 pool to pool fuel moves. We have developed the following questions:
Do you have clarity issues with your SFP; what is the perceived cause?
Do you use supplemental filtration (such as Tri-Nuc filters) to maintain clarity?
What permanently installed equipment do you use to maintain clarity?
Your response to any of the questions above will be much appreciated. Also, if you have a good procedure or have performed a modification to control or improve SFP clarity please include details to help us in our efforts.
Thanks, Andy
