R.E. Ginna is working to improve our practices related to FME around the SFP. We have developed the following questions:
What FME controls are in place for work around the SFP? Is there a project plan or FME plan in place?
Does your SFP have legacy foreign material (FM) in it?
If you have legacy FM, do you have a plan established to recover it long term?
How do you document and track FM in the SFP?
If you discover FM during the performance of other work, do you stop all work to recover FM, or proceed as long as you will not impact that location?
When recovering foreign material FM, do you have station personnel or contractors perform the work?
What tools/methods do you use to recover FM in the SFP?
Your response to any of the questions above will be much appreciated. Also, if you have a good procedure, project plan or FME plan that controls work around the spent fuel pool please forward it to me.
Thank you, Andy

R.E. Ginna is working to improve our practices related to FME around the SFP. We have developed the following questions:
What FME controls are in place for work around the SFP? Is there a project plan or FME plan in place? Response - The SFP is considered a High Risk FME Area (FMEA) per INPO 07-008,Guidelines for Achieving Excellence in FME. For large projects such as Refueling, Fuel Inspections, or our current Rerack there is a specific FME Plan in place. For normal maintenance activities, personnel would follow the guidance provided in the site FME procedure for a FMEA.
Does your SFP have legacy foreign material (FM) in it? Response - Yes
If you have legacy FM, do you have a plan established to recover it long term? Response - Yes. As an example, a year ago a lens gap from a plastic weir gate pressure gage fell into the SFP. We know its approximate location and during the current Rerack we will attempt to retrieve when we move those assemblies.
How do you document and track FM in the SFP? Response - A few years ago we started a Non-SNM tracking program and we include FM in that system. This log is maintained by Reactor Engineering.
If you discover FM during the performance of other work, do you stop all work to recover FM, or proceed as long as you will not impact that location? Response - It would depend on the FME Plan. If the item is immediately retrievable then it could be retrieved. If not immediately retrievable then work would be stopped and an FME Recovery Plan developed.
When recovering foreign material FM, do you have station personnel or contractors perform the work? Response - In most instances it has been the fuel vendor.
What tools/methods do you use to recover FM in the SFP? Response - Air-operated vise grips, LUVS (Light Underwater Vacuum System), or regulare tri-nuke vacuum with suction hose.
Your response to any of the questions above will be much appreciated. Also, if you have a good procedure, project plan or FME plan that controls work around the spent fuel pool please forward it to me.

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.

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? CPNPP does not have a chronic problem with water clarity
Do you use supplemental filtration (such as Tri-Nuc filters) to maintain clarity? No, our permanently installed equipment is sufficient.
What permanently installed equipment do you use to maintain clarity? During the normal cooling operation, a portion of the spent fuel pool water may be diverted through the purification loop which consists of a filter, demineralizer and resin trap. The design flowrate through the purification loop is a maximum of 250 gpm. The minimum flowrate is governed by the pressure drops in the associated filters, demineralizers and resin traps. A low flow condition may impact the performance of the purification loop and, depending upon a number of other conditions and variables, the ability to maintain the required water quality in the Spent Fuel Pools. However there is no explicit low flow design criteria for these loops.
A high differential pressure indication across the spent fuel pool demineralizers during normal purification operations identifies that it is time to replace the resins. The demineralizers are isolated and the resin is transferred to the liquid waste processing system by the spent resin sluice pump.
There is a skimmer loop which consists of skimmers, a strainer, a skimmer pump, and a filter. This loop normally operates to maintain surface water clarity in the pools. The design flow rate through the skimmer loop is 10 gpm.
Normally, Train A cooling and purification loops are used to service No. 1 spent fuel pool while Train B is used to service No. 2 spent fuel pool. The system is cross‑connected so Train A or B have the capability of cooling and/or purifying either spent fuel pool.
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.

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? Not in general. Main SFP visibility issue is after offload due to thermal affects (heat coming off the fuel) and soluble crud in the water (from all the fuel moves).
Do you use supplemental filtration (such as Tri-Nuc filters) to maintain clarity? No
What permanently installed equipment do you use to maintain clarity? Normal spent fuel pool cooling system consists of 1 (of 2) pump running, one heat exchanger, and part of the flow is diverted through a purification loop (resin bed and filter).

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.

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.
