neuter

In analyzing the neutron active detection , the neutron multiplication in the nuclear warheads induced by outer neutron source with different neutron energys is studied with numeral simulation , and the feasibility of through counting neutrons to determine the presence of high enrichment uranium ( heu ) in nuclear warhead has been proved . the method of detecting the warhead which contains heu pit by counting the released neut rons whose energy is higher than that of source neutron is studied . the feasibility of this method has been studied 對幾種主動探測核彈頭方法進行的研究中,首先對不同能量各向同性外源中子照射核彈頭的中子增殖行為進行了數值模擬,檢驗了用外源中子照射核彈頭后,通過測量瞬發中子在核彈頭中的增殖量,來證明核彈頭中高濃鈾存在的可行性;研究了用能量低于1mev的外中子源照射核彈頭,用測量核彈頭中裂變產生的高于源中子能量中子數的方法探測核彈頭,通過數值模擬分析了可行性。
