Popis: HBS and HPS versions using single-crystal tungsten or molybden alloys as a cladding of heat pipes joined outside the core of reactor with thermionic converters are considered. Solid solutions of uranium and tantalum carbides, uranium-zirconium carbonitride including cermet type with a matrix made of tungsten are also discussed as the fuels of HBS and HPS. A possibility to rise the heat pipes and thermionic converters service life up to 10 years at the operating temperature up to 1900 K by means of using of single crystal tungsten is shown. Application of carbide fuel ensure possibility to increase operational temperature of the fuel elements and corresponding increase of specific impulse HBS up to 800-850 sec.
