可靠而精确的计算方法是进行核数据基准检验必不可少的手段。一维扩散程序1DX曾准确而有效地用于ENDF/B核数据库的快堆基准检验。为此,我们在1DX基础上建立了NDP程序。可靠而精确的积分实验是核数据基准检验的积分依据。美国截面评价工作组将快堆基准做为检验ENDF/B库的主要积分依据。这不仅是因为当今核动力堆中快堆是其发展方向,而且不同能谱的基准快堆几乎复盖了核截面的整个能区,最有利于对核截面在全能区进行检验。我们用NDP程序和苏联26群邦达连柯群常数计算了美国检验ENDE/B-4 Reliable and accurate methods of calculation are essential tools for benchmarking nuclear data. One-dimensional diffusion program 1DX has been used accurately and efficiently for fast reactor benchmarking of ENDF / B nuclear databases. To this end, we have established a NDP program on the basis of 1DX. Reliable and accurate integral test is the basis for the test of nuclear data base. The United States Section Evaluation Working Group will be fast reactor benchmark as the main basis for testing ENDF / B library basis. This is not only because fast reactors in today’s nuclear power reactors are its development direction, but the reference fast reactors with different energy spectra cover almost the entire energy range of the nuclear cross section, which is most conducive to the verification of the nuclear cross section in the all-energy region. We calculated the US test ENDE / B-4
