Description
Summary:The design of the working section was developed and the hydraulic circuit of the TVS-MPEI experimental bench was modernized to study hydrodynamics and heat transfer in a fuel assembly with microfuel. Experimental studies were carried out to determine the pressure loss and hydraulic resistance coefficient of a cylindrical ball filling with the following operating parameters of the coolant: p = (2 ÷ 7) MPa, G = (0.05 ÷ 0.5) kg/s. The technology of installation, output and sealing of thermocouples at the work site has been developed. The first experimental data on the temperature distribution inside the ball filling were obtained.
