Question

What are critical mass and critical size of nuclear fuel?

Answer 1

Explanation:

Critical size is known as the size of nuclear reactor core which is specifically suitable for the nuclear reaction. Critical Mass is known as the minimum amount of the Mass of the fission material, that's is the minimum amount which just start the nuclear chain reaction.

Answer 2

A n s w e r : -

A critical mass is the smallest amount of fissile material needed for a sustained nuclear chain reaction. The critical mass of a fissionable material depends upon its nuclear properties (specifically, its nuclear fission cross-section), density, shape, enrichment, purity, temperature, and surroundings.
