二次中子源在中国实验快堆上应用的初步可行性分析
Preliminary Feasibility Analysis of Application of Secondary Neutron Source in China Experimental Fast Reactor
摘要
Abstract
To improve economic efficiency during the physical start-up of China Experimental Fast Reactor (CEFR), the feasibility of using secondary neutron source to replace 252Cf source was studied.The secondary neutron source was designed based on the principle of neutron generation of secondary source and with reference to relevant CEFR parameters.123Sb (n, γ) reaction rate and 9Be single nucleon (γ, n) reaction rate in the secondary source assembly were calculated by using MCNP code, and source strengths in different exposure conditions were obtained.Then the feasibility of applying the secondary source in CEFR physical start-up was analyzed.The calculation results show that the designed secondary neuron source assembly can meet the requirements of CEFR start-up in most operating conditions.The secondary neutron source designed in this paper and the calculation results can provide useful data for the application of secondary neutron source in CEFR start-up.关键词
