DEFINITION

Classification: 376/313

By filters, ion exchangers, or absorbers:

(under subclass 310) Subject matter wherein the impurity is removed from a fluid through the use of (a) a porous mass through which the fluid is passed to separate from it the material held in suspension, or (b) a composition of matter which has the property of replacing the charged specie of the material in solution with ions of the composition.

(1) Note. This and indented subclasses include filters at the coolant inlet and of, and integral with, the fuel assembly.
