摘要

In calculating the fission product decay heat, we have to pay attention to the so-called pandemonium problem. Total Absorption Gamma-ray Spectrometer method (TAGS) is expected to be free from this problem at least ideally. A new series of TAGS measurements is being performed by a European group and their first results for Tc-104 and -105 became available quite recently. Introducing the old and new TAGS data, we calculated and analyzed the FP decay heat for Pu-239 in the cooling time range from 1 to 10,000 s. Our result showed the significance of TAGS data to improve the FP decay heat only with experimentally obtained decay data without introducing any nuclear theory.
