动力堆辐照元件中燃耗测定和149Sm,150Sm含量,154Eu/155Eu,154Eu/152Eu比值与燃耗的关系
BURNUP MEASUREMENT AND ITS RELATION WITH THE AMOUNTS OF 149Sm AND 150Sm AND THE RATIOS OF 154Eu/155Eu AND 154Eu/152Eu IN THE SPENT FUEL OF A POWER REACTOR
【摘要】 本文用同位素稀释质谱法,以148Nd为燃耗监测体对某动力堆元件的燃耗进行了测定。还测定了裂变产物中的高中子毒物149Sm的含量。对150Sm的含量测定结果表明,它能反映出核燃料燃烧的程度,为一直线关系。γ谱法测得的154Eu/155Eu比值和燃耗呈曲线关系。
【Abstract】 The amounts of 148Nd, 149Sm and 150Sm by the isotope dilution mass spectrography and the ratios of 154Eu/155Eu and 154Eu/l52Eu by the γ-spec-trography in the spent fuel of a power reactor have been measured.The amounts of 150Sm is directly proportional to that of 148Nd and burn-up can be determined by 150Sm. Relation of the ratios of 154Eu/155Eu with respect to the burnup is plotted.
