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 d546-430 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 purple artisan keycap 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.
