Malaysian Alternative to International Reference Bentonite Buffer in Underground Nuclear Waste Repository

The performance of bentonite as buffer material in underground nuclear waste repository has been extensively being investigated all over the world. Over the years, almost exclusively, naturally occurring Wyoming sodium based bentonite (MX80) was tested as a reference buffer material. Other alternati...
