This screening addresses the critical characteristics for food industry type cans and containers used for handling and storage of special nuclear materials at the Plutonium Finishing Plant (PFP). This revision lists Critical Characteristics for two (2) large filtered containers, and associated shielding over-packs. These new containers are cded 'Nuclear Material Containers' (NMCs). They are supplied in various sizes, which can be nested, one inside another. The PFP will use NMCs with volumes up to 8 quarts as needed to over-pack largely bulged containers. This screening address the use of the vented over-pack container for transport of largely bulged food pack containers (or those containers with a potential for release of contamination) to a glovebox.
