Production and validation of nuclear reaction data

Various research collaborations with foreign organizations such as IAEA, OECD, ORNL, BNL, etc. have been performed and strengthened. By actively participating in meetings that are sponsored by IAEA and OECD, we could make a decision on the research directions for nuclear data and offer our nuclear data to the international community without difficulty. Nuclear data uncertainty has been co-studied with ORNL, the calculation of evaluation module for the resonance areas and evaluation of nuclear data for reactor structural materials have completed in cooperation with BNL. Nuclear data that we produced were to be listed in ENDF/B-VII.1. With regard to evaluation techniques, a program to tune model parameters were developed. Covariance data production and a comparative analysis between nuclear data libraries for evaluating uncertainty was performed. Nuclear Data Evaluation module for resonance region and Uncertainty assessment techniques of the nuclear reactor analysis codes were developed. Evaluation was performed on the core material for nuclear fusion, advanced fuel cycle, and structural materials. Uncertainty calculations in the criticality are performed by using nuclear cross section uncertainty analysis system such as ERRORJ-ANISN-SUSD3D and NJOY-DANTSYS-SUSD3D. The number of nuclear materials for the fast reactor, radiation shielding, and actinide are processed and produced multigroup libraries were provided to the researchers. We adjusted the experiments using facilities that are distributed in the domestic research institutes. To build nuclear data measurement system using an electron accelerator in the Korea Atomic Energy Research Institute, conceptual design for fast neutron target and facility was completed. Neutron cross-section, photonuclear reaction was measured by using an electron accelerator in the Pohang neutron facility, The detector has been developed for more accurate measurements. Charged particle induced nuclear reaction cross sections were measured by using Cyclotron in KIRAMS. Nuclear data induced by MeV neutron sources generated by VDG in KIGAM were measured
