Conference Article: HTGR spherical fuel elements of the monolithic type bound by pyrocarbon

Abstract

The technology of HTGR spherical fuel element fabrication being used is based on the application of methods of powder metallurgy, i.e. mould pressing followed by heat treatment. As a binder coal tar pitch or a variety of resins are used. Upon the research of the above methods for HTGR fuel element fabrication several new methods of carbon-graphite material production were developed on the base of porous filler volume densification by pyrocarbon, and these methods can be used successfully for the fabrication of HTGR fuel elements
