Effect of KLT-40S Fuel Assembly Design on Burnup Characteristics
Energies, 2023 The KLT-40S is a small modular reactor developed by Russia based on the KLT-40 reactor with two fuel assembly designs: a four-ring and a five-ring. Few studies have been published on fuel assembly and power-flattening designs for the KLT-40S.

Numerical simulation of the molten fuel relocation in fuel rod
Journal of Physics: Conference Series, 2019 Abstract Thermal destruction of fuel rods is one of the most hazardous accidents in nuclear power plants. Fuel melt contains a lot of fission products that can release and start to transport along reactor loops. Relocation of the fuel melt can change the power of reactor due to feedback between density of materials and neutron field in ...

Journal of Physics: Conference Series, 2019 Abstract To simulate fuel rod thermal destruction, analytical approaches were developed. Approaches are based on solving the Stefan problem and solving the equation of motion of the molten materials. The paper contains a brief description of the ways to obtain analytical solutions and applicability limits of the solutions. Calculation of
