医用同位素生产堆燃料溶液中碘价态研究

Valence Change of Iodine in the Fuel of Medical Isotope Production Reactor

摘要: 在模拟医用同位素生产堆（MIPR）运行体系中，研究了温度、时间、HNO₃浓度和γ辐照对碘价态变化的影响。研究结果和MIPR运行环境的分析表明，在MIPR运行后，燃料溶液中的碘大部分以氧化形态存在，MIPR燃料溶液中的¹³¹I生产只能提取到氧化态的碘。

Abstract: The valence change of iodine by temperature, time, concentration of HNO₃ and γ radiation in the mock-up system of a medical isotope production reactor (MIPR) was studied. The results and the analysis of the operation conditions of the MIPR indicate that most of iodine in the fuel is in higher oxidation states after operation, and only the oxidized states of ¹³¹I can be obtained with the MIPR.
