Wave nuclear burning in spherical geometry

Abstract

, and be this can be if we use the huge reserves of 238 U . This article aims to investigate the feasibility of implementing one of the regimes of a fundamentally new and not yet practically implemented process in nuclear energy (cid:22) the nuclear traveling wave in a uranium-plutonium medium, where plutonium-239 is formed from 238 U . A nuclear traveling wave may form in a uranium-plutonium medium as a moving wave of plutonium-239 (cid:28)ssion. This paper considers the possibility of the formation of such a wave in a spherical uranium-plutonium medium, and the study is conducted in spherical geometry. improved explicit-implicit numerical calculation scheme was used, which allowed us to increase the temporal step of the simulation.
