Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0032] Such as Figure 1 to Figure 5 A system for simulating the characteristics of a high-level radioactive waste geological disposal room is shown, which can simulate the thermal-hydraulic-mechanical-chemical coupling characteristics of a high-level radioactive waste geological disposal room, including water supply and gas supply control device 1, temperature control device 8, multi-field Coupling experimental device, measurement system, data acquisition system 10 and data processing system 19;

[0033] Among them, the system for simulating the characteristics of the geological disposal chamber of high-level radioactive waste takes the multi-field coupling experimental device as the core, and the multi-field coupling experimental device is a cylindrical multi-layer structure as a whole, and its outermost layer is a barrel-shaped stainless steel cha...

Abstract

The invention belongs to the technical field of nuclear waste treatment, and particularly relates to a system of simulating characteristics of a high-level waste geology treatment room, which aims to provide the system capable of simulating the heat-water-power-chemistry coupling characteristic of the high-level waste deep geology treatment room. The system comprises a water supplying and gas-supplying device (1), a temperature control device (8), a multi-field coupling experience device, a measuring system, a data collecting system (10) and a data processing system (19). The system uses the multi-field coupling experience device as a core, the outermost layer of the system is a barrel-like stainless cavity body (4) with a sealing cover, and the innermost layer of the system is a cylindrical shape for simulating a heater (3) of the high-level waste. The invention provides a bentonite heat-water-power-chemistry coupling experience device under the condition of the multi-field coupling, has the characteristics of high strength, small deformation, corrosion resistance, good sealing property, high measuring precision and the like, and is suitable for a mock-up long experience of the bentonite under the condition of a simulated treatment room.

Description

technical field [0001] The invention belongs to the technical field of nuclear waste disposal, and in particular relates to a simulation device for thermal-hydraulic-mechanical-chemical coupling characteristics of a deep geological disposal chamber for high-level radioactive waste. Background technique [0002] The development of the nuclear industry produces a large amount of nuclear waste, especially high-level nuclear waste. How to safely dispose of it has become an increasingly urgent environmental problem to be solved. At present, the international community tends to adopt the deep geological burial method for the disposal of high-level radioactive nuclear waste. my country has also made it clear that this approach is adopted for high-level radioactive waste repositories to prevent the leakage and migration of nuclides through natural and artificial barrier systems, so as to achieve the purpose of safe disposal of high-level radioactive waste. After the geological site...
