This paper introduces a computer code——ADHLW designed for calculatingthe radioactivity of each main radionuclide and the total radioactivity in high-level waste(HLW)solidified products,as well as for the distance and time-dependent dose rate insideand outside the solidified products.The code will be useful for siting and designingHLW repository in deep rock formation,and will provide a basis for the assessment ofdisposal project and its environmental impact.For validation,we have calculated the76-68 borosilicate...

This paper introduces a computer code——ADHLW designed for calculatingthe radioactivity of each main radionuclide and the total radioactivity in high-level waste(HLW)solidified products,as well as for the distance and time-dependent dose rate insideand outside the solidified products.The code will be useful for siting and designingHLW repository in deep rock formation,and will provide a basis for the assessment ofdisposal project and its environmental impact.For validation,we have calculated the76-68 borosilicate glass waste solidified products and compared the results obtained withthat of WAPPA code of USDOE,and with others.All results are comparable withinabout 10—15%.

在核废物深部地质处置科学研究过程中,提供一种长期稳定的模拟花岗岩裂隙水,用以模拟试验是非常有必要的。本文主要依照中国辐射防护研究院推荐的模拟花岗岩裂隙水修正配方,引用地球化学模式程序对其溶液的稳定性进行模拟计算,探讨配方中所存在的问题。结果表明:(1)在碱性条件下,若推荐配方为过饱和溶液,将有多种矿物沉淀,则不可能长期稳定;(2)若通过改变条件(如pH值、部分离子含量)进行反向模拟计算,则可以得到具有长期稳定性的花岗岩裂隙水模拟配方。
