An in-situ hydration treatment system for buffer materials in a repository

Abstract

The invention relates to an in-situ hydrating treatment system for a buffer material in disposal repository. The system comprises a water supply system which is arranged in a lateral lane of the disposal repository. The water supply system is mainly composed of a water guiding pipe system and a water pump. The water guiding pipe comprises an outer water guiding pipe arranged on the inner wall of the lateral lane and an inner water guiding pipe arranged out of a waste storage container. The outer water guiding pipe and the inner water guiding pipe extend along the length direction of the lateral lane and are composed of water guiding pipes which are arranged in parallel therebetween. Water injection holes are uniformly formed in the water guiding pipes, geotechnical cloth layers are arranged out of the water guiding pipes, and the outer water guiding pipe and the inner water guiding pipe are finally connected together, and water is injected through the water pump. The system provided by the invention can uniformly realize a hydrating process of a buffer material at a relatively high speed.

Description

technical field [0001] The invention relates to an in-situ test method for the buffer material of a repository, in particular to an in-situ hydration treatment system for the buffer material of a repository. Background technique [0002] In recent years, with the vigorous development of the national economy, energy shortage has gradually become a serious problem facing China. China has paid more and more attention to the use and development of nuclear energy. The use of nuclear energy will inevitably produce a large amount of nuclear waste. Therefore, the disposal of nuclear waste has become an urgent problem to be solved. [0003] For the disposal of high-level radioactive waste, the feasible solution generally accepted by the international community is to bury the high-level radioactive waste in a stable formation at a depth of 500-1000m underground: that is, after the high-level radioactive waste is solidified and filled, it is stored in the deep In the geological reposi...

Problems solved by technology

[0005] At present, most of the research on the hydration process in the laboratory is to inject water from the surface to simulate the effect of groundwater, but in the in situ test, using this method, the process is quite slow, and there is a difference between the water injection from the surface and the actual groundwater flow. Big difference, uneven hydration process
