Yes, a type of fast neutron (without a moderator) reactor called a breeder reactor can make plutonium fuel much faster than it consumes uranium fuel. If fueled with plutonium fuel instead of uranium fuel, it also makes more plutonium fuel than it consumes.
But all other reactor types are unable to do this (even though they all make some plutonium during operation).
Note: a slight variant of a breeder reactor sometimes called a burner reactor is designed to rapidly fission all actinides (elements from actinium up through all transuranics) to eliminate long lived isotopes from nuclear waste.

LaoYes, it is possible for a nuclear reactor to produce more fuel than it consumes through processes like breeding. Breeding involves converting non-fissile material into fissile material, allowing for the creation of more fuel. However, the economics and practicalities of implementing breeding in nuclear reactors can vary depending on factors such as reactor design and cost.

Which Fuel is used in Fast Breeder Reactor?
Fast Breeder Reactors typically use a combination of plutonium-239 and uranium-238 as fuel. This type of reactor produces more fissile material than it consumes, making it an efficient way to generate nuclear power.
Why did they add boron to water to dump on the nuclear reactor?
Boron helps to absorb neutrons in a nuclear reactor, which can help control the nuclear reaction and prevent a meltdown. By adding boron to water and then dumping it on the reactor, they can effectively shut down the nuclear reaction in case of an emergency.
What kind of toxic waste are produced by nuclear energy?
Nuclear energy produces radioactive waste, which can remain hazardous for thousands of years. This waste includes spent fuel rods, contaminated materials, and other byproducts of nuclear reactions. Safely storing and disposing of this waste is a major challenge for the industry.
Why must uranium be enriched before it can be used as a fuel source in a nuclear reactor?
Uranium must be enriched to increase the concentration of uranium-235 isotope, which is the isotope that undergoes fission in nuclear reactors. Natural uranium primarily consists of uranium-238, which is not as efficient at sustaining a nuclear chain reaction. Enrichment increases the proportion of uranium-235, making the fuel more suitable for use in reactors.
Do fossil fuels have a higher or lower energy content than a similar mass of nuclear fuel?
Nuclear fuel has a higher energy content than fossil fuels. A small amount of nuclear fuel can generate a significant amount of energy compared to a similar mass of fossil fuels due to the high energy density of nuclear reactions.
