The results show that the method is better than the method of counting prompt neutrons in distinguishing real and fake nuclear warheads 数值模拟表明,这种方法比计数瞬发中子总数有较大的优点,可用来探测铀为弹芯的核弹头。
~ ( 252 ) c _ f - source - driven neutron noise analysis method is a way of measuring and analyzing the reactivity of reactor or subcritical reactor , which detects subcritical neutron multiplication factor , prompt neutron decay constant , and so on ~ ( 252 ) c _ f源驱动噪声分析法是一种测量、分析反应堆和次临界系统的快速反应性的方法,可作为临界安全的瞬时检测方法。
In nuclear engineering, a prompt neutron is a neutron immediately emitted by a nuclear fission event, as opposed to a delayed neutron decay which can occur within the same context, emitted after beta decay of one of the fission products anytime from a few milliseconds to a few minutes later.
