The spent resin transfer pump, 3WSS-P6, is primarily used to:
transfer spent resin from various demins and ion exchangers to the spent resin hold tank, 3WSS-TK3
Why must the spent resin recycle pump, 3WSS-P2 have a flowpath established prior to starting the pump?
it is a positive displacement pump and there is no minimum flow recirculation path provided
Why is the spent resin dewatering tank level required to be kept greater than or equal to 10% after solid waste operations are complete?
ensure any spent resin remaining in the spent resin dewatering tank is covered
How is the discharge of the spent resin recycle pump, a positive displacement pump, protected from overpressure?
pump discharge pressure trip
Determine the method for transferring resin from a primary system demin or ion exchanger to the spent resin hold tank (TK3).
the spent resin transfer pump (P6) is the source of pressure to sluice resin out of the demin/ion exchanger to TK3
the purpose of the spent resin hold tank is:
to store the spent resin until it can be transferred to a shipping container
