Process Yield [Energy] Law and Legal Definition
According to 10 CFR 74.4 [Title 10 – Energy; Chapter I -- Nuclear Regulatory Commission; Part 74 -- Material Control and Accounting of Special Nuclear Material; Subpart A -- General Provisions], the term process yield means “the quantity of SSNM (Strategic Special Nuclear Material) actually removed from a unit process compared with the quantity predicted (based on a measured input) to be available for removal. Process yield differs from a process difference in that holdup and sidestreams are not measured or modeled.”
