Recent years, a lot of achievements on nuclear data evaluation and nuclear database set up et al., are obtained by China Nuclear Data Centre (CNDC). A new evaluated neutron data library CENDL-3.1, which contained 240 nuclei data file with ENDF6 format, is released and a lot of benchmark and data validation for this library have been performed. The nuclear data model study and code system improvement are done at CNDC and some code systems (UNF, MEND et al.) based on the updated study results is being used in the evaluation activities. As an important tendency of nuclear data application, the evaluated covariance les are become more and more important, so establishment of the producing method for the covariance files is one of the most important tasks for nuclear data researchers. A new evaluation system for evaluation the covariance le is being developing and some good results are obtained at CNDC. Some good improvements on the study of fission yield data evaluation and relative field have been carried out. A new semi-empirical model, which used to analyze and to describe the yield-energy relations and a new systematics on independent yield with Zp model are developed. The progress at CNDC about nuclear data evaluation, data process, validation and related research fields studies are mentioned in this presentation.
