Class Information
Number: 376/373
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
Description: Subject matter wherein the coolant is made to traverse a specified or predetermined route or channel within the reactor core or the route taken is such as to place the coolant into a pattern or network which serves to exert a particular effect upon the reactor or reaction.
