Description

technical field [0001] The invention relates to a steam consumption simulation device, in particular to a test system for simulating the steam consumption of a secondary circuit steam turbine. Background technique [0002] The pressurized water reactor nuclear reactor usually consists of a primary circuit and a secondary circuit. Therefore, in the reactor thermal hydraulic system test, it is necessary to simulate the two loops of the reactor separately. The main function of the primary loop of the reactor is to continuously transfer a large amount of heat energy generated by nuclear fission of the core to the secondary loop through the heat transfer tube of the steam generator through the circulating flow of the coolant. The saturated water in the secondary circuit (secondary side of the steam generator) undergoes a phase change after absorbing the heat energy given by the primary circuit to generate a large amount of steam. The steam is introduced into the steam turbine t...
