In a breeder reactor:

AMore fissile material is produced than is consumed ✓ Correct

BLess fissile material is produced than is consumed

CNeutrons are slowed down by a moderator

DU-238, a fissile material, is produced from Pu-239, a fertile material

Correct answer: (A) More fissile material is produced than is consumed

Explanation

In a breeder reactor more fissile material is created than is used up during operation.

It converts fertile atoms into new fissile atoms while the fission reaction proceeds.

Producing less fissile material than consumed would describe an ordinary, non-breeding reactor.

Slowing neutrons with a moderator is a feature of thermal reactors, not of a fast breeder.

The reversed claim is wrong, since fissile plutonium-239 forms from fertile uranium-238.

This surplus fuel lets breeders greatly extend the usable supply of nuclear material.
