Abstract

The paper describes the status of work on pyrocarbon-binder spherical fuel elements with thorium dioxide-base fuel for HTGR. Basic flow charts of manufacturing fuel microspheres, coated particles and spherical fuel elements are described. Results of investigations into the main characteristics of fuel elements and their constituents, including their operation under reactor irradiation conditions, are discussed. Some special features of the technology of pyrocarbon-bound (U,Th)O2 - base spherical FE are presented and reports the results from studies of their main characteristics.
