FUNCTIONAL REQUIREMENTS  Remove Particulates  Add Particulates  Interfaces with test loop DESIGN PARAMETERS  Cold Trap/Cold Finger  Release Mechanism  Defined Fittings and Locations Axiomatic Design

ProsCons Majority of particulate collects on the bottom and sides of 22 making them easier to remove Particulates are spread out over large area All sodium flow passes through a filter

ProsCons All sodium particulates are localized in the filters Sodium is trapped in two separate filters Complex to construct

Temperature Control Passive heating (turn off cooling) Active heating (heat w/ external source, e.g. heat exchanger from test section) Vibration Stirring Scraping Some combination of the above
