| 简介 |
PURPOSE : A method for forming a functional material layer in an inner wall of a nuclear fuel cladding tube is provided to prevent a crack due to remaining stress difference by processing a plating layer formed on the inner side of a nuclear fuel at low temperatures to remove the remaining stress of the plating layer.CONSTITUTION : A plating layer is formed on the inner side of a nuclear fuel cladding tube by electroplating functional materials. A functional material layer is formed by thermally processing the plating layer. A thermal process is performed at 100 to 550 degrees centigrade under vacuum, argon, or nitrogen atmospheres. The electroplating process is performed at room temperature or 90 degrees centigrade.[Reference numerals] (AA) Rare-earth(Ce-La alloy); (BB) Chrome plating layer; (CC) Coating material(9Cr-2W steel)COPYRIGHT KIPO 2013 |
