Institute Of Atomic Energy, Beijing, China.

4. HISTORICAL BACKGROUND AND INFORMATION

Since the 1950s, with the development and uses of nuclear energy, many fission product nuclear data libraries have emerged, and many measurements and evaluations on fission product nuclear data have been actively carried out. Since 1985, the Institute of Atomic Energy in Beijing has been working on a fission product yield library. In the first phase of the project, top priority was given to 10 fissioning systems. The 10 sets of yield are compiled in ENDF/B-V format and also in legible form. The project was carried out under the auspices of the IAEA Nuclear Data Section.

5. APPLICATION OF THE DATA

Fission yield data are important in the nuclear industry for the decay heat predictions of reactors, determination of nuclear fuel burnup, neutron dosimetry measurements, and nuclear physics calculations.

6. SOURCE AND SCOPE OF DATA

The sources of experimental fission yield data are the Rider library up to 1980, and the EXFOR library of IAEA. The 10 fissioning systems are: U-235T, U-235F, U-235HE, U-238F, U-238HE, Pu-239T, Pu-239F, Pu-241T, U-233T and Th-232F. Each of these involves 1170 fission product nuclides. For each of the nuclides, both independent and cumulative yields together with their uncertainties are given.
