Breeder or fast-neutron reactors generate more fuel than they use because
A)these reactors capture the energy of extra neutrons released by 235U fissions.
B)the Second Law of Thermodynamics does not apply to nuclear reactions.
C)of solar collectors that invest the energy of the sun into new fuel.
D)the heat that is usually released in standard reactors is mostly recaptured.

Question

Quizplus · Accepted Answer

Breeder or fast-neutron reactors use neutrons released during fission of 235U to convert non-fissile isotopes like 238U to fissile isotopes like 239Pu. This process generates more fuel (239Pu) than it uses (235U), resulting in a net gain of energy. The other options given are incorrect and do not accurately explain the concept of breeder reactors.
