Abstract

NECP-Bamboo is a PWR-core physics analysis software developed by the Nuclear Engineering Computational Physics (NECP) Laboratory at Xi'an Jiaotong University based on the improved two-step methodology. There are no engineering turning approximations so different PWR cores can be calculated using the same methodology setup. This paper calculated and summarized 64 cycles of 7 kinds of PWR cores. The fuel enrichments range from 1.8% to 4.45%, while burnable poisons contain borosilicate glass and gadolinium-doped fuels. The lattice structures in fuel assembly are either 17 × 17 or 15 × 15. Notably, the number of fuel assemblies in each core encompasses 121, 157, 177, or 193. Calculated parameters were compared with the corresponding Nuclear Power Plant (NPP) measurements, including critical boron concentration, temperature coefficient, rod cluster control assembly worth in the start-up tests, together with the critical boron concentration, and assembly radial relative power distributions in the power operation periods. All the statistical errors agree well with the corresponding acceptable safety limits.

期刊介绍： Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
