Problems solved by technology

[0003] At present, due to the limitations of technical requirements, neutron irradiation experiments, and radiation sources, it is only possible to predict the service life of the material in a nuclear power plant by simulating the corrosion behavior of the material under the condition of no ray radiation and neutron irradiation.
However, these experimental results can only partially represent the corrosion behavior of materials in actual working conditions, which leads to errors in the judgment of the service life of materials used in nuclear power plants, and seriously threatens the safety of nuclear power plants

Abstract

The invention discloses an online high-temperature and high-pressure radiation corrosion simulation system and method. The online high-temperature and high-pressure radiation corrosion simulation system comprises a second water storage tank, a high-pressure pump, a preheater, an autoclave, a condenser and a collecting tank which are sequentially connected into a ring shape through a pipeline; andradioactive sources are arranged on one side of the second water storage tank, and a suspension point is arranged in the autoclave. According to the online high-temperature and high-pressure radiationcorrosion simulation system and method, by arranging the radioactive sources on the outer side of the second water storage tank, water in the second water storage tank can be irradiated; through arrangement of the high-pressure pump and the preheater, the water entering the autoclave can be heated and pressurized, and thus the high-temperature and high-pressure radiation corrosion environment faced by a structural material can be simulated; and additionally, according to needs to the actual situation, the radioactive sources can also be moved away, at the moment, a device can simulate the corrosion situation of the related material under the high temperature and the high pressure, the various types of radioactive sources can further be arranged to radiate the water, and then multi-factorsynergistic corrosion under various radiation types is simulated.

Description

technical field [0001] The invention relates to the technical field of radiation corrosion simulation, in particular to an online high temperature and high pressure radiation corrosion simulation system and simulation method. Background technique [0002] With the increase of people's demand for energy, nuclear energy, as a clean and efficient energy source, has attracted more and more people's attention. However, during the operation of nuclear power plants, the internal fuel cladding, fuel assemblies and pipelines are not only subject to high temperature and high pressure water corrosion, but also are affected by multiple factors such as neutron irradiation and ray radiation. The existence of multiple factors complicates the corrosion behavior of materials, so obtaining the corrosion behavior of materials under multi-factor conditions in advance is very important for the safety of nuclear power plants. [0003] At present, due to the limitations of technical requirements,...
