Computational simulation of experiments performed using the BFS-2 critical facility to substantiate the BREST-OD-300 reactor design
摘要
The present paper considers the computational simulation of experiments performed on the BFS-88 critical assembly, which is a full-scale model of the BREST-OD-300 reactor core. Experimental research included the study of neutronic performance core characteristics, such as criticality and reactivity worth of the control and protection and passive feedback systems, as well as the measurement of the spatial distribution of power density and reactivity effects. Radiation characteristics and neutron kinetics of the assembly were examined. The computational simulation of the measurements substantiated the neutronic performance characteristics of the BREST-OD-300 core and verified the design codes.
