RE: Resin Intrusion in Nuclear Power Reactors
Lets see if I can remember this correctly....
There are filter beds designed into the coolant/letdown system down-stream
of the resin beds. The primary purpose of the filters (sometimes called RCS
filters) is to collect mobile resin beads. Applicable resin beds are
bypassed when their respective downstream filters are taken out-of-service
(e.g., for filter replacement).
Resin beads somehow bypassing the filter banks and introduced into the RCS
charging system would create an FME problem. A gross failure of a resin bed
would immediately create a letdown flow/pressure problem - an easy situation
to diagnose. Normal RCS letdown would be quickly isolated and the unit
placed on excess letdown until the affected resin bed was restored and the
RCS filters changed.
