| 摘 要： | 为了实现对自发裂变中子源能量、多重性和中子角关联分布的数值模拟，开发了根据裂变过程，逐步给出裂变中子多重性、能量和角分布等参数的NESF数值模拟程序，并将该程序集成到现有中子输运软件中.重点介绍我们开发的用于模拟自发裂变中子源能量、多重性和中子角关联分布的程序的背景、物理依据、程序流程，以及基于该程序开展的中子角关联分布特征与核部件特征关联的数值模拟.

| Abstract: | For numerical simulation of spontaneous fission neutron source energy, neutron multiplicity and neutron angular correlation distribution, a NESF numerical simulation program is developed to provide fission neutron multiplicity, energy, angular distribution and other parameters on basis of fission process. The program is integrated into existing neutron transport software. This report focuses on background, physical basis, and process of the program, as well as numerical simulation correlated to neutron angular correlation distribution characteristics and nuclear component characteristics. |
