球对称核爆炸早期的点动力学模型

Point kinetic model of the early phase of a spherically symmetric nuclear explosion

Andreas Aste

摘要:

本文提出了一个核裂变链式反应驱动瞬发超临界球体爆炸的简明点动力学模型。这些发现与Trinity的现有数据非常一致,Trinity是美国陆军作为曼哈顿计划的一部分进行的第一次核武器爆炸。结果是一个内爆装置含有纯钚-239,虽然该模型可以很容易地应用于,例如,铀235通过在模型中加入相应的源项,计算了含从反应堆燃料中回收的钚的裂变弹的失败概率和相应的产额,并由此计算了含有大量自发裂变的钚-240的裂变弹的失败概率和相应的产额。发展中国家或恐怖组织是否可以制造炸弹的相关问题可以通过这种方式解决。虽然回答这些问题所需的资料属于公共领域,但对于关心核爆炸物扩散的组织成员来说,很难从这一主题中得到一致的看法。

英文摘要:

A concise point kinetic model of the explosion of a prompt supercritical sphere driven by a nuclear fission chain reaction is presented. The findings are in good agreement with the data available for Trinity, the first detonation of a nuclear weapon conducted by the United States Army as part of the Manhattan project. Results are presented for an implosion device containing pure plutonium-239, although the model can be easily applied to, e.g., uranium-235. The fizzle probability and corresponding yield of a fission bomb containing plutonium recovered from reactor fuel and therefore containing significant amounts of spontaneously fissioning plutonium-240 which can induce a predetonation of the device is illustrated by adding a corresponding source term in the presented model. Related questions whether a bomb could be made by developing countries or terrorist organizations can be tackled this way. Although the information needed to answer such questions is in the public domain, it is difficult to extract a consistent picture of the subject for members of organizations who are concerned about the proliferation of nuclear explosives.
