Breeder reactor

Nuclear reactor generating more fissile material than it consumes

Breeder reactor

Summary

A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. These reactors can be fueled with more-commonly available isotopes of uranium and thorium, such as uranium-238 and thorium-232, as opposed to the rare uranium-235 which is used in conventional reactors. These materials are called fertile materials since they can be bred into fuel by these breeder reactors.

moved image of old US reactor to appropriate section, use BN-800 in lead, one of two operational breeder reactors

NPguy4/9/2026, 5:52:38 PM

Russia has BN-600 and BN-800; no others are operating commercially
