方法が論じられている。As a method for obtaining a vapor flow containing multiple uranium isotope elements, Japanese Patent Publication No. 13331/1983 discloses that a uranium ingot is held in a long crucible, and the uranium ingot is irradiated with an electron beam to locally heat it. Methods of obtaining the desired vapor flow are discussed.

するという問題がある。Therefore, materials with excellent heat resistance and corrosion resistance are required as materials for crucibles, which is an important issue to be solved. Japanese Patent Publication No. 57-13331 describes that the crucible can be prevented from becoming too hot by providing a passage in the crucible wall and circulating a cooling fluid therein. However, when the crucible is cooled, the heat input by the electron beam is wasted, resulting in a problem of worsening thermal economy.
