What is meant by critical mass in a nuclear chain reaction? |
| Answer» Solution :Critical MASS in a nuclear chain reaction is the minimum mass of FISSIONABLE material that WOULD sustain the nuclear chain reaction at a steady rate. The neutron reproduction factor K, in this CASE, becomes equal to one i.e., rate of production of NEUTRONS is just equal to the rate of loss of neutrons. | |
