use of polystyrene nanospheres in SNF

[Ed Myers]

David,

Polystyrene spheres have been used in the facility, but where they 
are allowed is heavily regulated.  The SpecMat committee and I will 
have to see your proposed process flow before a decision can be 
made.  The process flow should include all of your process steps and 
the requested equipment.

Regards,
Ed
