Class Information
Number: 376/370
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)
Description: Subject matter wherein one of the fluids is steam or vapor which is (a) formed at least in part during course of reaction, (b) separated as steam or vapor from another fluid, or (c) handled as such in some way internally or externally of the reactor.
