BURNUP MEASUREMENT AND ITS RELATION WITH THE AMOUNTS OF ~(149)Sm AND ~(150)Sm AND THE RATIOS OF ~(154)Eu/~(155)Eu AND ~(154)Eu/~(152)Eu IN THE SPENT FUEL OF A POWER REACTOR

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.
