Výroba litých komponentů ze slitiny MoNiCr pro reaktory IV. generace

Abstract

This thesis deals with materials to produce cast components for reactors cooled by molten salts. First, the history of nuclear reactors is outlined, especially reactors IV. generation. A reactor cooled by molten salts is discussed in more detail. This is followed by an analysis of materials which, due to their properties, are suitable for use in the environment of molten fluoride salts and neutron flux. These materials include nickel alloys, which are introduced in more detail and compared with each other. An integral part this thesis is the practical part, which describes the production of the pump impeller from MoNiCr alloy.
