Trojan had a similar problem with hot particles around the fuel pool. We
used the same methods as STP and had strict controls on the removal of
any material from the pool. Ropes hanging over the side were also a real
problem so nothing was allowed to be suspended from the edge of the pool.
We also found `nests' of hot particles under laundry storage racks and
inside electrical panels. Housekeeping just has to try to keep up.
Hope this helps

Palo Verde requests information on the following:
Palo Verde has been dealing with chronic personnel contamination
events due to discrete radioactive particles in our Fuel Buildings.
Extensive housekeeping and decontaminated efforts have had a
negligible impact and the primary source of contamination is suspected
to be the Spent Fuel Pool (SFP). With this in mind, have other stations:
1. Had similar challenges with contamination control/personnel
contamination events around your spent fuel pools? If so,
Did you identified any cause(s)
Did you implement any corrective actions such as clean-up of water
line residue, activity concentration reduction efforts, and filtration
specification or resin changes?
Any help / information would be greatly appreciated.
Seth.
