Experimental Validation of the Technical Characteristics of a Steam-Generator Cassette in the RITM-200 Reactor

Abstract

A high-efficiency once-through steam generator is used in the RITM-200 reactor for the universal nuclear icebreaker. The new design necessitated experimental validation of the technical characteristics of the steam generator taking into account the integral arrangement of the steam-generating block. To this end a model of the steam-generator cassette was developed and tested at OKBM Afrikantov. The experimental studies of the model of the steam-generator cassette confirmed the heat-engineering and hydrodynamic design characteristics of the steam generator in the RITM-200 reactor.
