Combination of Active and Passive Reactor Cavity Water Injection Cooling System Debugging Method

Abstract

The invention relates to a debugging method for a combined active and passive reactor water injection cooling system. The method is based on the design characteristics of the combination of active and passive reactor cavity water injection cooling systems. By analyzing various functions and configurations of the system, the system is designed. The commissioning test items to be carried out, the specific implementation plan and content of the commissioning test, the acceptance criteria of each test, the execution stages and the logical sequence of mutual execution, including system single equipment commissioning, system independent sub-function commissioning and system comprehensive performance debugging. The invention can comprehensively and efficiently verify the function of the system and the conformity with the design target of the system, and provides a strong guarantee for ensuring that the reactor cavity water injection cooling system can fully exert its inherent function when a serious accident occurs in a nuclear power plant.

Description

technical field [0001] The invention belongs to the debugging and design technology of nuclear power plants, and in particular relates to a debugging method for a reactor cavity water injection cooling system combined with active and passive. Background technique [0002] The commissioning of a nuclear power plant refers to all the activities that will be performed to make the structures, systems and components enter a certain operating mode after the installation work is basically completed, so as to conduct a comprehensive verification of the design, equipment manufacturing, construction and installation quality of the nuclear power plant to ensure that the nuclear power plant can operate in a certain manner. Continuous and stable operation under rated power, the whole process is mainly divided into two parts: non-nuclear test and nuclear test. Commissioning is not only the last step in the construction phase of a nuclear power plant, but also the first step in the operati...
