Evaluation method for high-level waste geological disposal storage yard address appropriateness on the basis of Delphi method

Abstract

The invention belongs to the field of nuclear installation decommissioning and radioactive waste governance, and particularly relates to an evaluation method for high-level waste geological disposal storage yard address appropriateness on the basis of a Delphi method. The method comprises the following steps that: S1: determining the quantitative evaluation index of high-level waste geological disposal storage yard address appropriateness; S2: constructing an index quantification rule and standard; S3: using the Delphi method to determine the weight of the index; and S4: calculating the final value of the high-level waste geological disposal storage yard address appropriateness. By use of the method, the establishment of the evaluation index is taken as a basis, the Delphi method is taken as a means to determine the weight of the index, the construction of the index quantification rule and standard is taken as a core, the problem of the quantitative evaluation of high-level waste geological disposal storage yard address appropriateness is solved, and the method is suitable for the quantitative evaluation of storage yard address appropriateness of a large and complex high-level waste geological disposal storage yard with an ultralong evaluation period.

Description

technical field [0001] The invention belongs to the field of nuclear facility decommissioning and radioactive waste treatment, and in particular relates to a method for evaluating the site suitability of a high-level radioactive waste geological disposal storehouse based on the Delphi method. Background technique [0002] High-level radioactive nuclear waste, referred to as high-level radioactive waste, has strong radioactivity, high toxicity, heat generation, and extremely long half-life of nuclides. Reliable means must be adopted to effectively isolate it from the human living environment. Judging from the current development situation in the world, it has become an international consensus that deep geological burial (in geological bodies about 500-1000 meters deep from the surface) and isolation from the biosphere is considered to be an effective and safe disposal method. The safe disposal of high-level radioactive waste faces a series of major and complex problems in ter...

Problems solved by technology

As mentioned above, the Delphi method itself is only a weight prediction method. Experts investigate the weight of indicators according to the prescribed procedures. Therefore, the Delphi method itself cannot perform quantitative evaluation of site suitability, but only provides an indispensable tool for quantitative evaluation of suitability.
