2023-02-10 Neutronics analysis of a subcritical blanket system driven by gas dynamic trap based fusion neutron source for 99Mo production doi:10.57760/sciencedb.07299 en In this work, we proposed a new design for 99Mo production based on LEU subcritical blanket system (SBS). The system is driven by a gas dynamic trap based fusion neutron source (GDT-FNS). The plasma parameters of the GDT-FNS system were simulated by the 1-D code DOL. Neutronics analysis of the production system has been performed with the SuperMC code. The data mainly including: the axial distribution of D-D neutron generation rate of GDT-FNS; the neutron spectrum in region of high neutron flux; the impact of varying uranium concentration; the ks varying with different reflector materials; the value of ks and A varying with thickness of Be reflector; the distributions of ks and average neutron flux (outside the shielding layer) varying with different shielding materials; the neutron flux and gamma flux outside the shielding layer and ks varying with thickness of W/B/PE shielding material; neutron flux distribution of SBS; neutron energy spectrum of different components in SBS; nuclear heat distribution in the central radial section of SBS.
