CRITICAL SIZE: The actual size of material which allows the escape of neutrons to such an extent that at least one neutron is positively left behind per fission reaction is known as critical size. Critical mass has always a definite value for any specific system. …

What affects critical mass?
The amount of a fissionable material’s critical mass depends on several factors; the shape of the material, its composition and density, and the level of purity. A sphere has the minimum possible surface area for a given mass, and hence minimizes the leakage of neutrons.
What happens when uranium reaches critical mass?
Assuming the material expands with temperature (enriched uranium-235 at room temperature for example), at an exactly critical state, it will become subcritical if warmed to lower density or become supercritical if cooled to higher density.

Critical mass is the point at which a product becomes self-sustaining in the market. It is difficult to determine exactly when that point will be reached or where exactly that point is – however, we can take action to develop KPIs which enable us to see if we are progressing towards critical mass.
