Iron Filtration

[LASKV@ccmail.ceco.com]

     Fellow Radsafers,
     
     Does anyone have information on Iron Pre-filters?  We are trying to 
     reduce iron inputs to our reactor vessel to aid in lowering our source 
     term.  Specifically,
     1. How much do they reduce iron concentrations?
     
     2. How much space do they occupy?
     
     3. What types of materials do they use?
     
     4. Do they exhibit any dose concerns?
     
     You can reply directly to me at LASKV@CECO.com
     
     Thanks in advance,
     
     John Van Horn
