Usually uranium enriched with the U-235 isotope, in the form of uranium dioxide. This is better than metallic uranium as it can stand higher temperature. Plutonium-239 can also be used if available, this has to be separated from spent uranium fuel by chemical means.

∙ 13y agoI'll list some of the more important products from nuclear fission and put them into three categories.
The Good:Neutrons - they have a short half-life so they don't contaminate the environment, and they allow sustainable fission in reactors to happen.Photons - they (x-rays, gamma rays, etc.) provide the energy that is converted and then distributed by nuclear reactors.
137Cs - it is one of the most used gamma-radiation energy sources for the calibration of medical and scientific instruments.
The Bad:137Cs - I'll put it here too since it's pretty long-lived (t1/2 = 30yrs.), and can contaminate the environment.90Sr - it easily contaminates calcium-deficient plants and has a half-life of 29yrs.
137Xe and 90Kr - these two are noble gases and so can easily diffuse throughout the atmosphere, decaying into longer-lived isotopes which can then contaminate.
The Ugly:129I, 131I, and 132I - these guys get collected and stored in the thyroid gland and are also 100% absorbed into the human gastrointestinal tract.3H, a.k.a., tritium - an aqueous solution of tritium can easily be absorbed through the skin.
99T - a VERY long lived beta emitter. It can chemically form into many hazardous and soluble compounds, and with a half-life of 211,000 years, it's not going away anytime soon.

Where does nuclear energy come from to make renewable energy work?
Nuclear energy and renewable energy are not related. Renewable energy does not use nuclear energy.
Do batteries use nuclear energy?
Batteries use chemical energy to create voltage to drive current flow. They do not use nuclear energy.
How do use the words nuclear energy in a sentence?
there was nuclear energy in the science experiment
Types of things that use nuclear energy?
Anything that uses electricity may use nuclear energy
Why does nuclear energy have radioactive stuff in it?
It is simply a fact that nuclear fission produces radioactive fission products
What products do you use the nuclear energy for?
To produce electricity
What energy do scientist predict that polymer products will increase the use of?
Nuclear energy
What do scientists predict that polymer products will increase the use of?
Nuclear energy
What does nuclear energy use to create its source of energy?
From the nuclear forces. An U-235 atom has a higher energy level than its daughter products; this is used in nuclear fission.
How does nuclear energy extracted from the ground?
We use uranium and products derived from it as our source of nuclear energy. Uranium ores must be mined from underground.
What are the waste by-products of nuclear energy?
popcicles
What problem is associated with the increase use of nuclear energy?
More radioactive waste products to store safely
What Does not use nuclear energy?
All material uses nuclear energy.
Where does nuclear energy come from to make renewable energy work?
Nuclear energy and renewable energy are not related. Renewable energy does not use nuclear energy.
What is the benefit of nuclear fusion and What is one thing nuclear fission and nuclear fusion have in common?
nuclear fusion make more energy and they both make energy and have waste products
Do batteries use nuclear energy?
Batteries use chemical energy to create voltage to drive current flow. They do not use nuclear energy.
What material does not use nuclear energy?
All material uses nuclear energy.
