After deriving the properties of neutron travel through materials, a detailed analysis is presented of how the critical mass of a fissile material, in both “bare” and “tampered” configurations, can be calculated. The calculations are applied to both uranium-235 and plutonium-239. Analytic ...

Mass spectrometry imaging (MSI) has evolved into a valuable tool across many fields of chemistry, biology, and medicine. However, arguably its greatest disadvantage is the difficulty in acquiring quantitative data regarding the surface concentration of the analyte(s) of interest. These difficulties lar...
What is a Nuclear Reaction? What are the Largest Non-Nuclear Explosions in History? What is Fermium? What is Plutonium? What is Uranium? Discussion Comments Byanon86793— On May 26, 2010 i would advise people to be careful with the numbers this site provides for critical mass. ...
We have chosen CShM over another method called "shape measure" (ShM)58 because it takes account of the distortion of center metal ion from the center of mass. The principle and compar- ison of the calculation method in CShM and ShM is described in Supplementary Information S7. The S ...

A MCNP study for a water-reflected sphere of plutonium metal water pseudo-solution was performed for a various ratios of ~(238)Pu to ~(239)Pu to develop minimum critical mass curves. The ~(238)Pu atom percent (at. %) was varied from 35 to 100 percent. It was demonstrated that at ~...
