A method of deep burial of long-lived radioactive waste and spent nuclear fuel by melting of the geological mass due to the residual heat release of radionuclides confined in a container is analyzed. A variant is proposed for regulating the power of heat release by adding relatively short-lived highly active radionuclides inside a capsule, which also accumulate during the burnout of nuclear fuel in reactors and are subject to disposal. An example of a calculation of the time-dependence of the depth of sinking of a capsule with radioactive waste and spent nuclear fuel with different compositions of the capsule filling is presented. Calculations show that by adding highly active isotopes it is possible to expand the capabilities of controlling the process of immersion of capsules with radioactive waste and spent nuclear fuel.

分析了一种通过封闭在容器中的放射性核素的余热释放而使地质物质熔化来深埋长寿命放射性废物和乏核燃料的方法。提出了一种通过在胶囊内添加寿命相对较短的高活性放射性核素来调节热释放功率的变体，这些放射性核素也在反应堆中的核燃料燃尽过程中积累并进行处置。介绍了计算具有放射性废物和废核燃料的胶囊下沉深度的时间依赖性的示例，其中胶囊填充物的成分不同。计算表明，通过添加高活性同位素，可以扩大控制放射性废物和乏核燃料浸入胶囊过程的能力。
