The experimental apparatus comprises the following components: a nuclear steam supply system simulator which comprises a higher water tank, a lower water tank, a main water tank, a water pump, an inlet valve, a water outlet valve, and a pipeline; a mother pipe simulator which comprises a main pipe and several draining units; and a main control bench which comprises a data acquisition module, a signal output module, a master control computer and related lines; the invention also provides the experimental method of the experimental apparatus. The experimental apparatus in the condition with low parameter and without irradiation can simulate and analyze dynamic characteristics of the multi-unit miniature modularized reactor system, and design and verify corresponding control schemes.

Description

technical field [0001] The invention belongs to the field of nuclear reactor control, and in particular relates to an experimental device and an experimental method for a multi-unit small modular reactor control system. Background technique [0002] Due to its high safety, good economy and short construction period, small modular reactors are one of the important development trends of nuclear energy technology. In order to achieve the purpose of large-scale power generation, such small-capacity reactors often adopt the form of multiple units arranged side by side. , this kind of reactor is defined as a multi-unit small modular reactor, and its structural diagram is shown in figure 1 . figure 1 In , several nuclear steam supply units (four units in the figure) supply steam to the same main pipe, and the main pipe gathers the steam to provide power for multiple steam turbines (two in the figure). Each nuclear steam supply unit mainly includes a core, a steam generator and a ...
