Increased Source Information of Used Reactors Research reactors have a wider array of designs than power reactors. Most are sodium-cooled and use fuel.Their used fuel generates less decay heat and their radionuclides are less enriched than that of power buy reactors. NRC staff has established a safety framework for new reactor design applications using mechanistic models to evaluate source terms. Many advanced reactor designs need fuel, which is enriched from 5% to 20% U-235. It allows them to be smaller and produce more power for a given volume of fuel.But the currently has no assured source. As a result, it could take a long time to develop these new fuels and to commercialize them for carbon-free energy.Until then, existing nuclear power plants can use by downblending it or recycling it from other used fuel. But that is not a viable long-term strategy. Relying on another country's would not revitalize nuclear manufacturing capabilities, and shipping it from abroad creates security, logistical and licensing issues that are unique. Uranium isotope that can sustain a chain reaction under reactor conditions, liberating energy by splitting into two smaller nuclei and releasing neutrons. The reactions are controlled and efficient for power production, but they require the right conditions to be sustained.Each atom of uranium-235 contains 92 protons and 143 neutrons, for a total atomic mass of 235 units. This makes it heavier than the chemically identical U-238, whose nuclei have a mass of 238 units. This difference in mass can be exploited by different enrichment processes.One process forces uranium hexafluoride gas under pressure through a series of fast spinning cylinders -- centrifuges. The centrifuges separate out the hexafluoride molecules that have more U-235 and leave a less enriched product behind. The process can be repeated several times, increasing the proportion of U-235. National labs have restarted production of rare actinide isotopes to meet a growing demand from chemists. Those isotopes are used in research to create new nuclear drugs to treat cancer and other diseases.Following the lanthanide elements, the actinide element series extends to lawrencium (atomic number 103). They are not found naturally and must be produced synthetically in particle accelerators or neutron bombardment reactors.Uranium and plutonium are used in nuclear weapons and power plants, while thorium is employed in gas mantles for nuclear used reactors and americium is utilized in smoke detectors. A better understanding of the behavior and properties of these materials is essential to their safer use.

The isotope of carbon known as carbon-14, for instance, is used to determine the age of artifacts and other organic materials. Its isotopic fingerprint also helps us understand our atmosphere and make better use of water resources.All elements have stable isotopes, but some naturally occurring nuclides are unstable and radioactive. When this happens, the neutrons that comprise their nuclei lose energy and emit radiation as alpha, beta and gamma particles. The energy from these particles can be captured and transformed into electricity by nuclear chemical reactors or particle accelerators (linear accelerators, cyclotrons). The Isotope Program provides the priority isotopes needed for basic research, commerce, medical diagnostics and treatment, oil and gas exploration, and national security.
