ISO 10981:2004规定了测定轻水反应堆、气冷反应堆和快堆辐照燃料硝酸溶液中铀浓度在0.1 g/l和400 g/l之间的分析方法。它规定了如何防止亚硝酸盐和钚离子的干扰。燃料溶液的其他成分不会产生干扰。
该方法适用于过程控制,但不适用于会计目的。
ISO 10981:2004 specifies an analytical method for determining the uranium concentration between 0,1 g/l and 400 g/l in nitric acid solutions of irradiated fuel from light-water reactors, gas-cooled reactors and fast-breeder reactors. It specifies how interference by nitrite and plutonium ions is prevented. The other constituents of fuel solutions do not interfere.
This method is suitable for process control, but not for accountancy purposes.
