Modularized layering support device for multi-container system

Abstract

The invention relates to a modularized layering support device for a multi-container system. The multi-container system comprises a pressure container, at least two steam generators and at least two main pumps, wherein the steam generators are arranged around the pressure container in a center-symmetric way; the main pumps are arranged around the pressure container in a center-symmetric way; the steam generators and the main pumps are alternatively arranged around the pressure container, and are uniformly distributed around the pressure container at intervals; the steam generators are respectively connected with the pressure container through first pipelines; the main pumps are respectively connected with the pressure container through second pipelines; the modularized layering support device comprises a first support unit and a third support unit. The modularized layering support device has the advantages that the first support unit and the third support unit are used for supporting the main equipment of a reactor loop by layers, the load on the main equipment is transferred to a foundation supporter, the heat displacement produced by a reactor is released, the inertial load produced by the periodical alternating load of marine environment is resisted, and the reliability is improved.

Description

technical field [0001] The present invention relates to the field of nuclear power, and more particularly, to a modular layered support device for a multi-vessel system. Background technique [0002] The reactor coolant system in the related art consists of main equipment such as a pressure vessel, a steam generator, and a main pump through pipelines to form a closed loop. When the stack is started and shut down under normal operating conditions, the main equipment in the system will generate thermal expansion and thermal displacement. [0003] Due to the large temperature span, if these thermal expansion and thermal displacement are completely restricted, the thermal stress on the equipment and supports will exceed the allowable stress and be damaged. [0004] On the basis of the above loads, the reactor coolant system in the marine environment is also superimposed with long-standing alternating loads and external shock loads. The alternating loads periodically induce rol...
