The breeding gain in case of thermal breeder reactor as compared to fast breeder reactor is

A Same
B Lower
C Higher
D Unity

Correct Answer: Lower

The breeding gain in case of thermal breeder reactor as compared to fast breeder reactor is lower.
Breeder reactors are also fast reactors. Fast neutrons are ideal for plutonium production because they are easily absorbed by U238 to create Pu239 and they cause less fission than thermal neutrons.
