【摘要】 针对一个放射性废物处置场围岩的不良性能,提出采用添加剂改良地球化学条件,建造地球化学工程屏障,将库体释放核素固定在库体附近,确保环境安全。还着重讨论了在不同地段固定不同核素的多重屏障设计,屏障的有效性实验,屏障的持久性实验及其评价方法。更多还原

【Abstract】 To counter the bad nature of the surrounding rocks on a radioactive waste disposal site, this (paper) presents a method to improve the geochemical conditions by adding agent so as to establish a (geochemical) barrier. This barrier can make the nuclear released from the waste storehouse stabilized near the storehouse to ensure safety of the environment. The paper emphatically discusses and studies the (multiple) barrier design to stabilize different nuclear in different segments, experiment of the addition agent for the barrier, experiment of the sustained agent for the barrier and the evaluation method.更多还原
