Сalculation and theoretical study of the dynamics of the passive heat removal system
Transactions of the Krylov State Research Centre, 2021 The paper proposes a theoretical and computational study of the dynamics of a passive heat removal system. In the computational part, the selected scheme is made by analogy with the first circuit of the monoblock steam generating unit “Beta”. In the course of the work, the equation of conservation of mass and energy for the pipe was considered when ...
