Do you have clarity issues with your SFP; what is the perceived cause?   Clarity is usually pretty good.  Once in a while the pool might get a little cloudy after extended periods of fuel movement but does not intefere with visibility

Do you use supplemental filtration (such as Tri-Nuc filters) to maintain clarity?  We do use a Tri-Nuke once in a while

What permanently installed equipment do you use to maintain clarity?  Installed filters and demin.

Subject: [Pwrrm] Spent Fuel Pool (SFP) Clarity

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
