CALCULATION OF A HEAT EXCHANGER FOR A SIMULATION INSTALLATION OF PROCESSES IN THE EXTERNAL COOLING CIRCUIT SYSTEM OF A NUCLEAR POWER PLANT

This article discusses the possibility of upgrading the setup for modeling processes in the external cooling loop of a nuclear power plant by replacing the heat exchanger unit with a plate heat exchanger. As a result of the design and hydraulic analysis, a heat exchanger with 33 plates operating on the principle of counter-current media was recommended, which allows achieving the required operating parameters of the setup. Compliance with operating modes, as well as optimal dimensions and configuration of the heat transfer surface were achieved. The efficiency of the selected design of the heat exchanger, its characteristics and the presence of a reserve on the heat exchange surface were confirmed.
