Abstract The circulation of liquid fuel is a feature of innovative nuclear reactors, such as Molten-Salt Reactors, and requires a specific neutronics model to take it into account. In this paper we propose a point kinetics model, for a hypothetical one-dimensional reactor, that is based upon and improves one that already exists in the literature. The model is therefore solved numerically and compared to spatial kinetics, which is considered to be the exact solution. The approximations that were done, which best portray the phenomena associated to the problem, are discussed to explain the improvements obtained with the proposed model.
