The critical mass of fissionable material is the largest mass necessary to sustain a nuclear fission chain reaction. single mass
value that can sustain a nuclear fission chain reaction. mass at the critical point, which can sustain a nuclear fission chain reaction. smallest mass necessary to sustain a nuclear fission chain reaction.
The critical mass for a fissionable material is the smallest and the lowest quantity of a particular fissile material required to generate a self-sustaining fission chain reaction under specified conditions. The size's features are determined by a number of variables. Examples include;
The type of fissile material employed, its purity as well as concentration, the shape of the surrounding reaction system e.t.c.
