I'm looking for a product to:
1. Spray on highly contaminated items as they leave the refueling cavity/SFP to keep contamination from spreading.
&
2. Spray on clean items before they enter the pools to keep the contamination from sticking.
I don't know that a single product will fill both roles, so any techniques that help with one or the other are also appreciated!
I started my research on specific plant threads where I know techs have chemicals they like, but (as Sun Dog pointed out), a combined thread might help other people with a similar question...
This discussion about anti-contamination additives has some great information in it. But, five years from now someone searching for answers will not find them because they are imbedded in Cooper and SONGS threads. Maybe this topic deserves a stand along header.
Okay. Here's what has been said so far...everyone please contribute other techniques they have used to control contamination...esp. on items entering & leaving the fuel pools.
(From the Cooper thread)
What is the brand name of the fixative we sprayed on items coming out of the refueling cavity?
20% glyserol/water works nicely in a bug sprayer. I remember using WD-40 alot in the drywell at Cooper, worked good for valves but probably not for cavity. Are you trying to keep control of airborne or are you wanting to lock down contamination to prevent spread?
I just looked at the chem permit for WD-40 at the current plant...can't be used on piping internals...oh well... 
What are you trying to keep it out of? To bad about wd-40 ,thats a good idea. How bout a spray on car wax? It is relativly inert and biodegradable.Shoudnt glom up the works. Hows that for tech speak?
I've never heard of anyone using carwax - not sure if I could get a chem permit for it...has to be low-chlorides, compatible with the resin beds, etc. I'll kick it around with the chemistry gurus. Thanks for the idea.
(From the SONGS thread)
During the ISFSI project (projects?), the equipment was sprayed with some chemical before it went in the pool (...to keep the contamination from sticking). What brand of chemical was it?
Considering some of the adventures provided by Procurement and Maintenance in the past, I wouldn't be surprised if that chemical was known as "ScotchgardTM"
alconox
Excellent! Thanks!
Any opinion on whether it worked well enough to recommend?
...That stuff works pretty well, but if you use it in your cavity after drain down it is a serious safety issue. It is as if you are walking on vasiline coated stainless. I remember it being difficult to climb the rungs to exit without losing footing. Keeps the contamination from floating away though.
I don't see "Keeping things from sticking" in the product discription:

It's my experience with it that there is no residue. It neither interfeers with footing, nor causes contamination to not stick to it.
Yes, once rinsed. What I was referring to is the way we used it at SONGS with the cavity. Gotta go down there to rinse, and until it is rinsed it was very slippery. I don't remember using it as a preventative measure to keep things from becoming contaminated prior to being submerged in contaminated water, but it works well to prevent airborn on large, highly contaminated areas. We have also had tremendous success with a 20% glycerol/water mixture here at Humboldt. We used it in bug sprayers while removing and packaging our fuel racks. Wrap it or paint it are the most effective ways to prevent something getting contaminated. Alconox would simply wash away once dunked I think.
Our water is somewhere around -4 Uci/ML (Cs-137, Am-241, Pu-239, Sr-90...sounds like fun huh?!), we can use as much water as we like. We don't use anything other than water on the way in, and water on the way out. Many many times our cords and fuel tools come out of the water <1K/<20 from just using water and a sprayer. That might not be an option at a running plant, just wanted to share the experience.
