地下盐穴处理核废料的方法

核废料对环境和人类安全具有较大危害，如何安全高效处理常常是困扰人类的棘手问题，目前认为有效的处理方式是深部埋藏处理，利用盐穴进行核废料的深埋处理是一种较为安全的方法。盐穴就是在地下盐层中通过钻井，利用水循环的方法，将盐层溶解，最终形成一个体积较大的空洞。利用地下盐穴可以进行各种工业废料的埋藏处理，特别是对具有放射性污染的核废料。建设埋藏放射性核废料的盐穴需要选择地质条件好，具有良好封闭性的盐层中，造穴方式主要是通过水溶洗盐形成地下溶洞。埋藏核废料需要通过一系列的特定工艺才能完成，放射性核废料埋藏处理后需要进行监测以防止产生污染事故。一般来说，由于地下盐穴埋深大、盐穴封闭性好，具有较高的安全性。利用盐穴进行核废料的埋藏具有费用低、容量大、占地少、安全性高等优点，是一种可以推广应用的核废料处理新方法。

Using Salt Cavern Storages to Dispose Nuclear Garbage

Nuclear garbage does great harms to environment and human security, how to deal with nuclear garbage is a very difficult problem, normally, to store nuclear garbage in deep underground seems an efficient method. Salt caverns are underground cavity formed by drilling and water circular melting salt in underground salt layer. Salt cavern can be used for disposing and embedding many kinds of industry garbage especially for disposing radiated nuclear garbage. In order to build salt caverns it is very important to choose good geological condition especially good salt formation. It is necessary to use special technology to embed nuclear garbage. Monitoring environment to prevent pollution is very important. Using salt cavern to dispose garbage is quite safe because the salt cavern is in deep underground and it has good sealing diagnostic. Large capacity, high security , save money and land surface are three advantages of salt cavern storage and this method can be recommended for disposing nuclear garbage.
