JENDL FP decay data file 2011 and fission yields data file 2011

Katakura, Junichi

The decay and fission yield data of fission products were compiled as JENDL FP decay data file 2011 (JENDL/FPD-2011) and JENDL FP fission yields data file 2011 (JENDL/FPY-2011). After the release of the JENDL FP decay data file 2000 file which was released in 2000, new measured data have been accumulated and new TAGS (Total Absorption -ray Spectroscopy) data have been published. The JENDL/FPD-2011 file was then compiled to reflect the new measured data. In order to keep the consistency between the number of the nuclides contained, fission yields file, JENDL/FPY-2011 was also compiled. The decay heat calculations for various kinds of fissioning nuclides were performed to confirm the validity of the JENDL/FPD-2011 and JENDL/FPY-2011 files. The calculated results showed good agreement with the measured data. The uncertainty analyses of the decay heat calculation were carried out with the method of sensitivity analysis.
