Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The advanced pressurized water reactor nuclear power plant is based on the second generation improved pressurized water reactor nuclear power plant, and the rapid cooling function of the primary circuit is introduced, which will inevitably cause changes in the related content of the commissioning design method. The rapid cooling of the primary circuit is a brand-new function. Since there is no relevant debugging experience, the present invention provides a design method for the debugging of the rapid cooling function of the primary circuit of the advanced pressurized water reactor nuclear pow...

Abstract

The invention provides a design method for debugging a primary loop rapid cooling function of an advanced pressurized water reactor nuclear power plant, which comprises the following steps: (1) analyzing system configuration and functions of the advanced pressurized water reactor nuclear power plant, analyzing the requirement of the rapid cooling function of the primary loop of the advanced pressurized water reactor nuclear power plant, and formulating a debugging purpose; (2) formulating an acceptance criterion of the function according to a principle of a primary loop rapid cooling functionbased on carding analysis of system configuration and the function; (3) designing debugging time based on an acceptance criterion of primary loop rapid cooling function debugging and in combination with an atmospheric release valve pressure set value curve; (4) designing initial conditions of a debugging test according to system configuration and functions of the advanced pressurized water reactornuclear power plant; and (5) designing the test content in the debugging process. According to the invention, the blank of the debugging method for the rapid cooling function of the primary loop of the advanced pressurized water reactor nuclear power plant is filled, and the safety, high efficiency and orderliness of the debugging work of the advanced pressurized water reactor nuclear power plantare ensured.

Description

technical field [0001] The invention belongs to the design technology of nuclear power plants, and in particular relates to a design method for quick cooling function debugging of a primary circuit of an advanced pressurized water reactor nuclear power plant. 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 debugging 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 fir...
