For an atomic reactor being critical, the ratio (r ) of the average number of neutrons produced and used in chain reaction

A

1. Is less than one

B

2. Is equal to one

C

3. Is greater than one

D

4. Depends on the mass of fissionable material

Text Solution

Verified by Experts

The correct Answer is:
C
for a chain reaction, the number of neutrons produced should be greater than the number of neutrons used. Hence r gt 1
