ABSTRACT:
A method for treating water in a Boiling Water Reactor system including filtration through a four component system including ion exchange resins and an inert fiber is provided, as well as a method for preparing and depositing the filter compounds. The method overcomes problems of plugging and trimethylamine release, and allows for better absorption of iron oxides present in BWR condensate, while reducing the amount of radioactive waste material to be disposed of.
