At present, the technology of reactor neutron noise is developing rapidly, which can not only be used to measure some intrinsic parameters of the reactor core, but also be used for core fault diagnosis. The theoretical solution of reactor neutron noi

We apply the Lagrange-mesh method to discretize continuum states of weakly bound nuclei for continuum-discretized coupled-channel (CDCC) calculations of three-body breakup reactions. This discretization method is compared with the bin method, which i

Neutron flux field changes in terms of intensity and spectrum from time to time in nuclear reactors. Considering this effect more faithfully, high order neutronic-depletion coupling strategies were shown to be advantageous over traditional ones. Whil

High order neutronic-depletion coupling strategies achieve better simulation performance against traditional strategies, at the cost of demanding variable coefficient depletion equations rather than constant ones to be solved. Through results compari

To kinetically model implosion- and explosion-related phenomena, we present a theoretical framework for constructing a discrete Boltzmann model (DBM) with spherical symmetry in spherical coordinates. To achieve this goal, a key technique is to use lo
