Nuclear wasteforms are the first barrier preventing the release of radionuclides
into environment. It is important that these forms are properly engineered to ensure that
storage and disposal facilities are acting as designed. Cementation of nuclear wastes is a
mature and reliable technology used to immobilise different waste types. Cementitious
wasteforms are briefly discussed with focus on their containment performance. An overview of methods is given to test
wasteforms leaching performance and models used.
Keywords: Cementitious wasteform, leaching mechanism, modelling, performance, radioactive wastes.
