Nuclear data activities in China

The scientific research on nuclear physics started in China in late 1950s. At that time, a research reactor and some accelerators were built in the Institute of Atomic Energy, Beijing, and nuclear data measurement was carried out. Nuclear data compilation and evaluation were begun systematically only in 1975 when the Chinese Nuclear Data Center (CNDC) and the Chinese Nuclear Data Coordination Network (CNDCN) were set up in order to meet the requirement for developing nuclear energy, science and engineering technology. Since China was not an IAEA member at that time, only very few data from foreign publications were able to be obtained, and the own evaluation had to be done to serve our users. This situation has changed since the CNDC established the contact with IAEA/NDS, JAERI/NDC and BNL/NNDC in 1980. Especially in 1984, when the People's Republic of China became an IAEA member, international cooperation and exchange increased. CNDC, CNDCN, working groups and Chinese Committee of Nuclear Data and their objectives are described. The activities on nuclear data evaluation, the progress of nuclear data measurement and the development for future are reported. (K.I.)
