用浅地层埋藏的方式处置低水平放射性固体废物(LLW),是日本核废物管理的基本方针之一。由于海洋投弃受阻,这种处置方式的现实性增大了。然而,与海洋处置相比,采用这种处置方式,废物就置于日本国土之内,与人类环境接近,更受到日本国民的关注。为了证明LLW浅地层处置的安全可靠性,使国民对此放心,日本有关研究单位对此进行了广泛的研究。 Disposal of low level radioactive solid waste (LLW) by means of shallow burial is one of the basic guidelines for Japan’s nuclear waste management. Due to the obstruction of ocean abandonment, the reality of this approach has increased. However, compared with the disposal of the ocean, using this disposal method, the wastes are placed within the territory of Japan and are close to the human environment and have drawn the attention of Japanese nationals. In order to prove the safety and reliability of shallow LLW disposal, so that nationals can rest assured that the Japanese research unit conducted extensive research.
