Subject: [Pwrrm] Spent Fuel Pool (SFP) Clarity
Sent by: pwrrm@retaqs.com

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?
Response - We've had issue with water clarity especially at Unit 2 where we have Boraflex in the spent fuel racks. As the Boraflex degrades it creates silica which turns the spent fuel pool milky white after several spent fuel pool moves.

Do you use supplemental filtration (such as Tri-Nuc filters) to maintain clarity?
Response -Yes, several years ago we started placing a Tri-Nuke in the spent fuel pool during outages and this has greatly improved the spent fuel pool clarity. We actually do this for both units now. I believe we use a 1 micron filter.

What permanently installed equipment do you use to maintain clarity?
Response - Normal spent fuel filtration system with Purolite NRW-35 LC mixed bed resin and Purolite NRW 501P OH - LC anion resin.

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
