“…On the other hand, JENDL is theoretically corrected for pandemonium [8] and this fact complicates the comparison. As is seen in figure 5, TAGS data improves the consistency with the Yayoi measurement [10] overall. The gross-theory prediction based on Method 2 almost follows the TAGS up to several hundred second after the fission burst.…”

Abstract. On the basis of the recent knowledge that the decay data measured by Total Absorption Gamma-ray Spectrometer (TAGS) is free from the so-called pandemonium, the prediction power of the gross theory of beta-decay was studied. By comparing the theoretical prediction with the INEL/TAGS data, we conclude that the gross theory predicts well the total energy release, or E β + E γ . However, when E β and E γ are dealt with separately, the prediction power of the theory has a limitation. This is one of the reasons why we need further TAGS measurements.

“…Some examples can be found in the reviews of Schrock (Schrock, 1979), Tobias (Tobias, 1980) and Tasaka . Nowadays the results of decay heat calculations are compared with the measurements of Akiyama et al (Akiyama, 1982), Dickens et al (Dickens, 1981), (Dickens, 1980) and Nguyen et al (Nguyen, 1997). Decay heat benchmarchs can be found in the work of Tobias (Tobias, 1989), which is considered the standard in the field.…”

“…To demonstrate usefulness of the hybrid method, it is applied to examining the consistency among macroscopicmeasurement data of contemporary use. They are the decay heat powers for five fast and three thermal fissioning systems, that were measured at YAYOI reactor of the University of Tokyo [3][4][5][6] and at Oak Ridge National Laboratory (ORNL), 7,8) respectively. The FP fission yields and decay data needed for this analysis are taken from ENDF/B-VI.…”

We propose a new "hybrid" method for calculating the aggregate decay heat from fission product nuclides after a fission burst. The decay heat from a given fissioning system is expressed as a linear combination of macroscopicmeasurement data for other fissioning systems with a small residual term. This method is based on the linearity of the decay heat to the fission yield. The coefficients in the linear combination are obtained from fitting the fission yield of the given fissioning system with a linear combination of fission yields of other fissioning systems. To demonstrate usefulness of this method, it is applied to examining the consistency among measured decay heat powers of five fast and three thermal neutron induced fissions. The hybrid-method calculations agree well with the measurements and usual summation calculations at cooling times before 4,000 s, except for a γ component measurement of the 235 U thermal fission at about 2,000 s. These results indicate the consistency and reliability of the decay heat evaluation for these systems with the above exception. Furthermore, they also imply usefulness of the present method in predicting the decay heat of other fissioning systems, for which no measurements have been performed so far.
