Non destructive detection process for nuclear fuel rods

阅读：92发布：2022-01-28

专利汇可以提供Non destructive detection process for nuclear fuel rods专利检索，专利查询，专利分析的服务。并且A method of detecting moisture and reactive gases in assembled nuclear fuel rods is disclosed in which an alloy of zirconium, nickel and titanium is added to the fuel rod. The fuel rod is uniformly heated for a sufficient time to vaporize moisture in the fuel rod enabling reaction between the alloy and the moisture and reactive gases. The presence of reaction products containing hydrogen can be detected by neutron radiography.，下面是Non destructive detection process for nuclear fuel rods专利的具体信息内容。

权利要求
