Abstract
The status of Chinese Evaluated Nuclear Data Library (CENDL) and the relevant CENDL project are introduced in this paper. Recently, a new version CENDL-3.2b0 was being prepared on the basis of the previous CENDL-3.1. The data in the light and actinide nuclide regions are updated from CENDL-3.1, and the new evaluations and calculations are performed mainly around structure and fission product nuclide regions. Covariance was also evaluated for structure and actinide nuclides. At the same time, the methodologies are systematically developed to fulfil the requirements of evaluations for CENDL-3.2b0. The updated nuclear reaction models for light and middle-heavy nuclides, non-model dependent nuclear data evaluation, covariance evaluation approaches, systematics, and integral validation system of nuclear data are incorporated in present CENDL project. The future developments are also planned.
Highlights
With the current prosperity and development of nuclear applications in China, more requirements of the fundamental nuclear data are proposed from Chinese domestic users
A new version of Chinese Evaluated Nuclear Data Library (CENDL) (CENDL-3.2b0) is nearly obtained, which involves the complete set of neutron induced reaction data below neutron energy at 20 MeV. activation, decay data and fission yield files etc
The latest CENDL-3.2b0 and the recent research work in CENDL project are introduced in this paper
Summary
With the current prosperity and development of nuclear applications in China, more requirements of the fundamental nuclear data are proposed from Chinese domestic users. In order to meet the diversified requirements and produce more high quality data to users, a CENDL project has been carrying out in China Nuclear Data Centre (CNDC), and China Nuclear Data Coordination Network (CNDCN) to systematically develop the methodologies in nuclear data evaluation and measurement. As the most important output of CENDL project, different versions of Chinese Evaluated Nuclear Data Library (CENDL) library (CENDL2, 2.1, 3.1) were released in the past, and used for some domestic and abroad users. The status of CENDL-3.2b0 is outlined in Sect. The related methodologies are presented in Sect. The main process of revises and modifications will be presented in the following subsections
