Abstract

Le problème du traitement des déchets, et tout particulièrement des déchets radioactifs, constitue un problème de société important. Afin de résoudre ce problème de manière appropriée, la présente invention a pour but d'améliorer la technique décrite dans un « procédé de traitement de substitution de couches profondes de boue pour déchets» (JP3000193) inventé en 1999. Dans la boue des couches profondes se trouvent des failles, des couches de sable et des couches de gravier, constituant des veines aquifères souterraines. Une eau polluée provenant des déchets ayant subi un traitement de substitution de couches profondes de boue risque de polluer l'eau souterraine en passant à travers la couche de terre ou les veines aquifères souterraines. C'est pourquoi, selon le procédé de traitement de substitution de couches profondes de boue pour déchets, avant d'effectuer un traitement d'injection des déchets dans des couches profondes de boue, une argile hydrofuge (de protection contre les rayonnements) est injectée au préalable, laquelle argile hydrofuge injectée est caractéristique en ce qu'elle bloque les déchets ainsi injectés et l'eau souterraine des couches profondes de boue.
