Description

Radionuclides are contained in the matrix of spent fuel and are released at the rate that the fuel matrix dissolves. The rate of matrix dissolution is expected to be determined by the rate of supply of oxidants, which may be influenced by hydrogen buildup, or, alternatively, by the solubility limitation of U(IV).
