Various effects of magnetite on international simple glass (ISG) dissolution: implications for the long-term durability of nuclear glasses

Geochemistry: towards durable nuclear glasses Immobilization in glass based hosts is the current geological method for disposal of long-lived radioactive waste from used nuclear fuels. A key factor that has to be understood is the fundamental mechanism that controls the glass dissolution in a geolog...
