Özet:

 A series of experiments were conducted an investigation into the amount of erosion, size of eroded particles, and swelling area of physically purified and compacted bentonite under different flow rates. Dynamic light scattering methodDLS was used to determine the size and amount of eroded particles and Autocad programme was used to determine the swelling area.Where compacted bentonite and crushed granite come into contact, groundwater plays an important role in the erosion of bentonite.Contact of compacted bentonite with water, its saturation with water and its subsequent swelling and entry into the voids around it are the primary steps for the formation of colloid particles. Factors affecting the erosion of compacted bentonite are groundwater flow rate, ionic strength of the water contacting the bentonite, pH of the water, etc. The groundwater to which the compacted bentonite buffer will be exposed during the designed service life of the compacted bentonite buffer reduces the robustness of the bentonite buffer.Erosion of compacted bentonite not only affects its physical stability but also causes the transport of radionuclides it absorbs.An experimental methodology is presented. The experimental results showed that with increasing flow rate the amount of eroded bentonite increases and the swelling area increases. No correlation was found between the flow rate and the size of the eroded particles.

 Fiziksel olarak saflaştırılmış ve sıkıştırılmış bentonitin farklı akış hızları altında erozyon miktarı, aşınan parçacıkların boyutu ve şişme alanı üzerine bir dizi deney yapılmıştır. Aşınan parçacıkların boyutunu ve miktarını belirlemek için dinamik ışık saçılımı yöntemi DLS ve şişme alanını belirlemek için Autocad programı kullanılmıştır. Sıkıştırılmış bentonit ve kırılmış granitin temas ettiği yerlerde, yeraltı suyu bentonitin aşınmasında önemli bir rol oynar. Sıkıştırılmış bentonitin su ile teması, su ile doygunluğu ve ardından şişmesi ve etrafındaki boşluklara girmesi, kolloid parçacıkların oluşumu için birincil adımlardır. Sıkıştırılmış bentonitin aşınmasını etkileyen faktörler yeraltı suyu akış hızı, bentonitle temas eden suyun iyonik gücü, suyun pHı vb.dir. Sıkıştırılmış bentonit tamponun tasarlanan hizmet ömrü boyunca maruz kalacağı yeraltı suyu bentonit tamponun sağlamlığını azaltır Sıkıştırılmış bentonitin erozyonu sadece fiziksel stabilitesini etkilemekle kalmaz, aynı zamanda emdiği radyonüklitlerin taşınmasına da neden olur Deneysel bir metodoloji sunulmuştur. Deneysel sonuçlar, artan akış hızı ile aşınan bentonit miktarının arttığını ve şişme alanının arttığını göstermiştir. Akış hızı ile aşınan parçacıkların boyutu arasında bir korelasyon bulunamamıştır.
