An elementary method to determine the critical mass of a sphere of fissile material based on a separation of neutron transport and nuclear reaction processes
确定 fissile 材料球体临界质量的简易方法:基于中子输运与核反应过程的分离
专题命中 扩散模型 :diffusion(abstract)
AI总结 本文提出一种基于中子输运与核反应过程分离的简易方法,通过设定中子数量不随时间变化的阈值条件,推导出临界半径表达式,无需求解扩散方程,并验证了其与已知临界质量的吻合度。
