Abstract
The Nuclear Reaction Data Centres (NRDC) collaborate on worldwide compilation and dissemination of experimental nuclear reaction data by developing and maintaining the EXFOR database. With the growing interests in the fission product yields of various projectiles and a wide range of energies, several evaluation activities are ongoing. In line with these activities, the IAEA conducted completeness check of fission product yield data in EXFOR against two experimental datasets developed by the ENDF and UKFY library evaluators. The present status and statistics of these datasets as well as the result of the EXFOR completeness review are presented.
Highlights
The fission product yield (FPY) is an important ingredient of nuclear data in both fundamental physics and nuclear applications
We report the current status of our assessment including the number of relevant FPY data identified for additional EXFOR compilation as well as statistics of projectiles and target nuclides in the ENDF-B/VI and UKFY3.0 evaluation summaries
Even if all data in the reference have been already compiled, the reference must be added to the EXFOR entry as an additional reference. This is because it will be an evidence that Nuclear Reaction Data Centres (NRDC) has already checked the reference, and EXFOR users will find the FPY data set by using the reference as a key
Summary
The fission product yield (FPY) is an important ingredient of nuclear data in both fundamental physics and nuclear applications. The Technical Meeting on “Fission Product Yields: current status and perspectives” (2016) [3] addressed the importance of the experimental and the evaluated FPY data dissemination. The EXFOR database contains a wide range of physical quantities of nuclear reactions including FPY. The NDS plans to launch a new CRP in 2020 to update the evaluated FPY data for the neutron-induced fission of some important actinides. We report the current status of our assessment including the number of relevant FPY data identified for additional EXFOR compilation as well as statistics of projectiles and target nuclides in the ENDF-B/VI and UKFY3.0 evaluation summaries
