Research on Application of Neutron Coincidence Counting in Attribute Determination of Plutonium

摘要: 中子符合计数在核材料认证和管理中有着广泛的应用．系统阐述了中子符合计数的基本原理，对“点模型”公式作了推导．利用MCNP4B程序实现了中子符合计数的数值模拟.Neutron coincidence counting is widely used in the authentication and management of nuclear material. The basic principles of coincidence counting and the derivation of "point model" formulae of "point model" are introduced in this paper. The numerical simulation of the coincidence counting is implemented by use of the MCNP4B package.
