Hydrogenation method and hydrogenation test piece

摘要

PPROBLEM TO BE SOLVED: To provide a test piece preparing method capable of controlling a hydrogen concentration in metal and a deposit situation of a hydride, to some extent, and allowing easily hydrogenation, and a test piece prepared by the preparing method. PSOLUTION: This test piece preparing method has the first process for attaching hydrogen permeable metal or an alloy thereof on one face of the zirconium alloy thin test piece, the second process for bringing the one face attached with the hydrogen permeable metal or the alloy thereof into contact with an aqueous solution of low dissolved oxygen containing a hydroxide of a dissolved hydrogen alkali metal as a solute, or pure water, and for bringing the the other face of the test piece into contact with water or an aqueous solution not accelerating oxidation of the test piece, and the third process for heating to a high temperature the test piece with the one face brought into contact with the aqueous solution of low dissolved oxygen containing the hydroxide of the dissolved hydrogen alkali metal as the solute, or the pure water, and with the other face brought into contact with the water or the aqueous solution not accelerating the oxidation of the test piece.
