dc.description.abstract© 2021 National Research Center Kurchatov Institute. All rights reserved.The paper aims at studying peculiarities in isotope composition of thorium blanket under irradiation by fusion neutron source (FNS) in hybrid thermonuclear reactor (HTR). High-energy (14 MeV) component of neutron spectrum in thorium HTR blanket can produce nontraditional fissile mixture including not only 233U, but also 231Pa, 232U and 234U. The extraction of such non-traditional fuel from a spent Th-blanket and its utilization in traditional nuclear power reactors could increase fuel burnup and contribute to nuclear weapon nonproliferation. The results of a comprehensive investigation of the above positive effects, which included high-precision neutronics analyses of a HTR's Th blanket, are presented. The chosen model of HTR allowed the formation of high-energy neutron spectrum in Th-blanket with significant fraction of 14-MeV neutrons; it appeared that threshold (n, 2n)- and (n, 3n)-reactions are able to produce significant amounts of non-traditional target isotopes 231Pa and 232U; it was shown that accumulation of non-traditional target isotopes weakened substantially in depth of Th-blanket. It is therefore reasonable to look for optimal thickness of Th-blanket and optimal inventory of natural thorium.
