Abstract
The updated Chinese Evaluated Nuclear Data Library CENDL-3.1 is an important achievement based on the nuclear data evaluation works in recent years, at China Nuclear Data Center (CNDC) in cooperation with China Nuclear Data Coordination Network (CNDCN). CENDL-3.1 contains the evaluated data for reactions with incident neutrons on 240 nuclides (from 1H to 249Cf) in energy region of 10-5 eV-20MeV. All data obtained according to the evaluations of experimental data and the predictions of the nuclear reaction model calculations. For most important nuclei of this library, the benchmark testing and validations have been performed, the comparisons with other nuclear data libraries (ENDF/B, JENDL, BROND, JEF, et al.) have been done. The testing version of CENDL-3.1 is CENDL-3.0, which has been provided for China domestic users. Follow the using back feed of CENDL-3.0, a lot of improvement has been done. The CENDL3.1 is provided for all users by ENDF format and is released to the world in the end of 2009. The overview, evaluation methodology and some important results of new evaluations, benchmark testing and validations for this library will be introduced in this contribution.
