某近地表处置场废物处置码放工艺优化研究

针对我国西南某近地表处置场原设计码放方案在实际应用中存在诸如处置单元容积利用率降低等相关问题,本文对原设计码放方案进行了介绍并提出了新的码放设计方案,又从施工成本、码放耗时、辐射剂量和国外同类处置场码放方式四个方面对优化后的码放方案进行了效果分析和对比。分析对比结果表明,经优化后的码放方案较原设计方案更切合实际处置需求,处置单元容积利用率得到显著提高,个别优化码放方案已获得成功实践应用,并取得预期设计效果。

Research on waste stacking optimization of disposal process in a near surface disposal site

In view of the practical application of the original design disposal process of a near surface disposal site,there are related problems such as the reduction of volume utilization rate of disposal unit.This paper optimizes the original design scheme and puts forward a new design.The effects of the optimized design were analyzed from three aspects:construction cost,time,radiation dose and similar disposal site.The comparison results show that the optimized stacking plan is more suitable for the actual disposal requirements than the original design.The volume utilization rate of the disposal unit has been significantly improved.And the successful practice of the individual optimized stacking plan also achieved the expected design effect.
