Problems solved by technology

However, due to the differences in the standards followed and the design of containment structures and functions, there are large differences in the design of the integrity test of each nuclear reactor type containment in terms of depressurization rate, pressure step and duration, and test content of each step. There may be adverse effects such as unreasonable design of the pressure ladder, too long continuous test of the ladder, or imperfect design of the buck-boost curve.

Embodiment 1

[0073] For details, see figure 1 , described below.

[0074] (1) Carding of containment boundary penetrations and process pipelines

[0075] Based on the requirements of my country's nuclear safety regulations, guidelines and standards, combined with the structural design of the reactor-type containment, all process pipelines and penetrations through the containment were sorted out, and the configuration of each process pipeline and penetrations was analyzed in the form of a list. and function. The formation list is shown in Table 1:

Abstract

The invention relates to the field of nuclear power design, in particular to a design method for the integrity test of the containment of an advanced pressurized water reactor nuclear power plant. The design method for the containment integrity test of the advanced pressurized water reactor nuclear power plant includes the following steps: step S1: combing the containment boundary penetrations and process pipelines; step S2: designing the prerequisites for the realization of the containment integrity; step S3: based on Design of test items required for containment functions; Step S4: Design of pressure ladders for the integrity of the containment and design of the buck-boost rate; Step S5: Form the design of the overall test plan for the containment of the advanced pressurized water reactor nuclear power unit. The invention guarantees the safety and practicability of the test to the greatest extent, and at the same time has a great positive effect on improving the availability of the nuclear power plant.

Description

technical field [0001] The invention relates to the field of nuclear power design, in particular to a design method for the integrity test of the containment of an advanced pressurized water reactor nuclear power plant. Background technique [0002] As the last barrier to limit the release of radioactive substances to the environment, the containment of a pressurized water reactor nuclear power plant undertakes the safety of containing radioactive substances, shielding radiation and protecting the reactor from external natural and man-made events under normal operation and accident conditions Function. The design of the containment shall ensure that any radioactive release from the nuclear power plant to the environment is kept as low as reasonably practicable, and does not exceed the regulatory discharge limit for radioactive release under operating conditions and does not exceed the allowable level of radioactive release under accident conditions. Accept the limit. Moreo...
