Class Information
Number: 376/376
Name: Induced nuclear reactions: processes, systems, and elements > Reactor structures > Circulating fluid within reactor > Plural fluids or a fluid in plural phases circulating within reactor (e.g., pressure tube reactors) > With formation, separation, or manipulation of a vapor (e.g., boiling water reactor (bwr) type) > Having specified fluid flow path or pattern within reactor core > With plural, coolant passes through reactor core > Re-entrant type
Description: Subject matter wherein the plural coolant passes, the coolant flows first along one flow path in a fuel element structure in one direction and then flow through a different flow path in the same fuel element structure in the reverse direction.
