Abstract
Accurate and reliable nuclear decay data libraries are essential for calculation and design of the advanced nuclear systems. To meet the requirements of decay heat calculation, burn-up calculation, analysis neutrino spectra anomaly and the other related studies, the evaluated nuclear decay data sublibrary for fission product has been developed and constituted for the first time in China based on the several main national evaluated data libraries in the world. About 1415 nuclides were included in present database. And two major data format, that's ENSDF and ENDF were provided. Some decay heat calculation, reactor neutrino spectra analysis and decay chain design needed in fission yield evaluation were performed to test the accuracy and reliability of the nuclear decay data sublibrary.
Highlights
Evaluated nuclear structure and decay data are widely used in science, industry, medicine and agriculture
The decay data of fission products, actinides and their decay products are extremely important in nuclear applications such as burn-up analysis and decay heat calculation of fission products
All of the evaluated data have been converted into ENDF-6 format
Summary
Evaluated nuclear structure and decay data are widely used in science, industry, medicine and agriculture. The decay data of fission products, actinides and their decay products are extremely important in nuclear applications such as burn-up analysis and decay heat calculation of fission products. To meet these nuclear application needs, the fission product decay data library should be developed. The information from such databases can be widely used in calculations of induced activation, transmutation of isotopes, and heat production. The brief instructions of status and progress of the decay data sublibrary are presented
