FREE RUNNING TURBO-CIRCULATORS FOR GAS COOLED REACTORS

摘要

The particular system here considered is one aiming at isolation of the primary coolant gas from the main part of the working cycle in a manner which may allow of operation of the reactor with bare fuel elements, without any shaft seal, or main turbine contamination problem.nBasically the scheme consists of employing a primary gas coolant circuit, circulation in which is accomplished by a totally enclosed and self-operating compressor-turbine system having no external shaft or power connection, and therefore no seal problem. Heat is rejected through a heat exchanger to a secondary system which could be either an open, or closed circuit gas turbine, or a steam cycle, depending on the temperature range contemplated.
