Neutronic Calculations for Certain Americium Mixed Fuels and Clads in a Boiling Water Reactor

Frontiers in Energy Research, 2021
In this study, a Boiling Water Reactor (BWR) design was made using the Monte Carlo (MCNPX) method. The reactor core in the designed BWR system was divided into an 8 × 8 square lattice with a constant pitch of 30.48 cm.

Comparison of the minor actinide transmutation efficiency in models of a fast neutron uranium-thorium fueled reactor [PDF]

Nuclear Energy and Technology, 2022
In terms of nuclear raw materials, the issue of involving thorium in the fuel cycle is hardly very relevant. However, in view of the large-scale nuclear power development, the use of thorium seems to be quite natural and reasonable.
