本文将我国古墓葬和中低放废物陆地浅埋处置在选址、工程结构、设计原理和施工方法等方面进行了类比分析。分析结果表明,我国古墓葬对中低放废物陆地浅埋处置是很好的类似物,古墓及其随葬品长期保存的完好性说明了选择适宜的场址、合理的工程结构和良好的回填材料及科学的施工方法后,中低放废物陆地浅埋处置是安全的。对我国2个墓葬回填材料的测试结果表明,古墓葬材料具有良好的抗渗性,其渗透系数为1.5×10 ̄(-8)cm/s,对Co和Cs吸附能力很强,分配系数分别为1.2×10 ̄4和2.1×10 ̄4mL/g,延迟系数分别为4.4×10 ̄4和7.7×10 ̄4;这些材料良好的性能保证了古墓寿命的长期性,可考虑作为中低放废物陆地浅埋处置工程中的回填材料。
In this paper, the ancient tombs and low-level waste landfill shallow disposal site in China, engineering structure, design principles and construction methods for analogy. The analysis shows that the ancient tombs in our country are good analogs for the shallow land disposal of low and medium level radioactive waste. The long-term preservation of the ancient tombs and their burial goods shows the proper site, reasonable engineering structure and good backfill Materials and scientific methods of construction, low-level waste landfill shallow disposal is safe. The test results of two tomographic backfill materials in China show that the material of the ancient tombs has good impermeability and permeability coefficient of 1.5 × 10 -8 cm / s, which has strong adsorption capacity for Co and Cs The coefficients are 1.2 × 10 -4 and 2.1 × 10 -4 mL / g respectively, with the delay coefficients of 4.4 × 10 -4 and 7.7 × 10 4, respectively. The good performance of these materials ensures that the ancient tombs The long-term life expectancy can be considered as a backfill material for the land-fill disposal of low and medium-level radioactive waste.
