Engineered barriers for radioactive waste confinement

摘要: Nuclear power plants generate long-lived radioactive waste of high toxicity. The security assessment repositories destined to definitive confinement has been studied for several decades. Deep geological are technically feasible and begin be built by some pioneer countries. scientific evaluation interactions between the different engineered barriers is laboratory experiments, natural analogues modeling studies. three methods able represent validate main geochemical processes that take place in near field. This paper reviews technical basis concept disposal, with particular focus on study applied stability bentonite barrier.
