چکیده
The paper defines the term “concept of geological disposal” radioactive waste. international and national experience disposal concept development is analyzed. peculiarities safety contribution from natural engineered barriers repository for different types formations are described. It shown that includes selection host formation, determination desired situation, as well list barriers, taking into account radwaste inventory. a mandatory initial step in site selection, concepts differ significantly define criteria, primarily terms depth, thickness geometric dimensions suitable formation. Engineered barrier systems rocks have almost same set components. However, relative role differs significantly. This especially true design time radionuclide containment. In crystalline formations, play major this sense. Their life hundreds thousands years. Natural provide conditions maintaining tightness containers much possible. rock salts, situation reversed - designed to facilitate fastest recovery preservation properties environment. Here, container clay has intermediate position: tens also at stage research Ukrainian most promising waste Precambrian within Chornobyl Exclusion Zone. Here covered by sedimentary with developed system aquifers. These can be considered an additional sorption filtration barriers. Only case when negative results Zone will obtained, it necessary proceed detailed study other regions types.

Disposal of Radioactive Waste
Perhaps the most important single problem arising from the increasing use of atomic energy for peaceful purposes is how to dispose of the growing amounts of radioactive waste. Many of its complex aspects were discussed at the scientific conference on the disposal of radioactive waste held by IAEA in Monaco from 16 to 21 November 1959. The conference was organized jointly with UNESCO, with the c...

متن کاملCements in Radioactive Waste Disposal
The use of cement and concrete to immobilise radioactive waste is complicated by the wideranging nature of inorganic cementing agents available as well as the range of service environments in which cement is used and the different functions expected of cement. For example, Portland cement based concretes are widely used as structural materials for construction of vaults and tunnels. These const...
متن کاملDisposal of low-level radioactive waste.
The Act encouraged states to form regional compacts for the disposal of low-level radioactive waste (LLRW). The Act contained both positive and negative incentives. The positive incentive was a provision that allowed compacts to restrict access to their regional LLRW disposal facility to member states beginning in 1993, thus limiting the amount of waste disposed of in any state hosting a region...
