摘要
利用MCNPx软件对主动中子多重符合测量技术涉及的源-样耦合常数、增殖系数进行理论模拟,获得了不同形态样品两参量间的经验公式,初步分析了影响源-样耦合常数的主要因素,为HEU中235U质量的认证测量及探测精度的提高奠定了重要的理论基础。
Coupling and multiplication involved in the measurement technology of active neutron multiplicity counting were simulated by MCNPx in this paper , and the empirical formulas of two parameters from different samples were achieved .The main factor effecting coupling was analyzed preliminary , which laid the important theoretical basis for the verification measurement and detection precision of the 235 U mass in HEU.
