The results show that the method is better than the method of counting prompt neutrons in distinguishing real and fake nuclear warheads 數(shù)值模擬表明,這種方法比計數(shù)瞬發(fā)中子總數(shù)有較大的優(yōu)點,可用來探測鈾為彈芯的核彈頭。
~ ( 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源驅(qū)動噪聲分析法是一種測量、分析反應堆和次臨界系統(tǒng)的快速反應性的方法,可作為臨界安全的瞬時檢測方法。
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.
