| Abstract: | The nuclear data for minor actinides with high accuracy are playing an important role in nuclear technology applications, including reactor design and operation, spent fuel cycle concepts, estimation of the amount of minor actinides in high burn-up reactors and the minor actinides transmutation. The classification of nuclear data and nuclear date library were described in this paper, and the procedure of neutron nuclear data evaluation was introduced. As an example, the evaluation of 234U(n,f) and 237Np(n,2... |
