1 2000 Im m obiliz ation of Hy drog en Is otope s,,,,,,,,, H/ M 2.0,. H/ M A bs tract Storage of hydrogen isotope gas in a cylinder is a w ell established technology. How ever, Immobilization in the solid form is preferr ed for long - term st or age of r adioactive isotope gas because of the concern for leakage of the gas. T he experimental thermodynamic P - C- T data show that T i, Zr and U soak up hydrogen isotope gas at a temperature of a few hundred and modest pressures. Eventually compounds are form ed in the metal m atrices upon cooling having the appr oximate stoichiometry MH2 or MH He.
