Most water moderated reactors use yellowcake powder: a uranium oxide enriched to 3% uranium-235. A few reactors use metallic uranium, sometimes enriched past 20%. Some experimental reactors use plutonium or mixed uranium & plutonium.

Is fusion reaction limitless?
Fusion reactions are not limitless. The fusion process can exhaust the supply of fuel and cause fusion to stop. Additionally, there are fusion processes that are not exothermic, but are endothermic and require energy to be put in to sustain them. Without the requisite input energy, fusion ceases.
What causes radioactive explosions?
An uncontrolled neutron chain reaction in a supercritical mass of fissile material.Very high temperature and pressure, enough to ignite thermonuclear fusion in fusion fuel.
Is it a fission or fusion reaction?
Fission and fusion are different nuclear reactions.
How does the fuel source solar energy make energy?
The source of solar energy is the sun. The sun contains hydrogen, which by fusion, is converted to helium. The fusion reaction gives off solar energy. See related link.
How to make a model of fusion reaction?
There is a nice illustration of solar fusion at the link given below
What is true is true regarding hydrogen fuel cells and hydrogen fuel cells and hydrogen fusion?
More mass is converted to energy in a fusion reaction than in a chemical reaction, such as that found in a fuel cell. - APEX
Is a nuclear fusion nonrenewable?
yes, once the fuel is consumed the reaction ends.
Does combustion fuel the sun?
no combustion dose not fuel the sun but the sun is fueled by a nuclear reaction known as fusion.
What is the role of hydrogen gas in the sun?
The hydrogen in the Sun is fuel for the nuclear fusion reaction.
Is nuclear fusion a nonrenewable energy?
yes, once the fuel is consumed the reaction ends.
Which of the following is true regarding hydrogen fuel cells and hydrogen fusion?
The amount of mass that "disappears" in the fusion of two hydrogen atoms is more than the amount of mass that "disappears" when two atoms are used in a fuel cell.the amount of mass that dissapears.........ect
What is the difference between hydrogen fuel cells and hydrogen fusion?
More energy is produced per reaction in a fusion reaction than in a fuel cell. -Apex
Is fusion reaction limitless?
Fusion reactions are not limitless. The fusion process can exhaust the supply of fuel and cause fusion to stop. Additionally, there are fusion processes that are not exothermic, but are endothermic and require energy to be put in to sustain them. Without the requisite input energy, fusion ceases.
Does fusion reaction occur in an atomic bomb?
They have a starter in a bomb and what this will do is shoot a neutron in the nuclear fuel starting a chain reaction
How does the sun use up its fuel?
All stars- including our sun- are an ongoing nuclear fusion reaction- hydrogen is fused into helium. The hydrogen is consumed in that reaction.
What causes radioactive explosions?
An uncontrolled neutron chain reaction in a supercritical mass of fissile material.Very high temperature and pressure, enough to ignite thermonuclear fusion in fusion fuel.
How stars grow old and die?
When stars "age", they spend their fuel source in a nuclear reaction (usually nuclear fusion).
