| description | With the intention of developing the decomposition process of tritiated compounds, ZrNi alloy was taken up as one of proper materials and its methane decomposition properties were experimentally investigated in a laboratory-scale flowing gas system. Methane was selected as a typical tritiated compound because of being known to be hardly decomposed and little data.
