What is reaction about nuclear fuel that can take a man in just two weeks?

You presumably mean the radiation from an exposed piece of nuclear fuel (used, not new), which will be so intense that it will kill a person with only a short exposure, though the radiation sickness will take a week or so to cause death.

What fuel is used in nuclear power plants?
A nuclear reactor is a device to initiate, control, and sustain a nuclear chain reaction. Nuclear power is energy produced from controlled nuclear reactions. When it comes to just standard fuel across the table it would have to be: Plutonium, Uranium, and Thorium.
Is fossil fuel nuclear energy?
No because fossil fuel is its own energy from decayed things just like nuclear has its own.
How is a nuclear reaction controlled?
Nuclear fission reactions usually depend on neutrons released by fission, which cause more fission in a chain reaction. The neutrons are in what is termed a neutron flux, which really means just that there are a lot of them there. If the flux is insufficient, the chain reaction stops. If it is too dense, the reaction overheats, which can lead to meltdown. Clearly, a way to control this is necessary. The control rods are made of materials that absorb neutrons. By adjusting them, the density of the neutron flux can be increased and the fuel made hotter, or it can be decreased, and the fuel made cooler. Adjusting them means changing their exposure to the fuel, for example, by changing how far they go into the fuel. They can be used to stop the chain reaction by inserting all of them all the way.
The nuclear fuel in the Sun is?
the main fuel the sun uses
Where is Iran's nuclear power plant?
Bushehr-fuel loading has just started
Why is it nuclear power plants will not used other elements in the periodic table except for uranium plutonium and thorium as fuel in the reactor?
reactors cannot operate on fuel that is unable to support a neutron chain reaction in at least one of its isotopes.actually all the transuranic elements, not just plutonium, make excelent reactor fuel.
Where was nuclear fission first used?
The first nuclear reactor was built at Chicago in 1942, to demonstrate that a chain reaction was possible and to get some basic data. It was just a pile of graphite bricks with natural U fuel, and operated at a very low power level, just a few watts. This was part of the Manhattan WW2 project to develop the A bomb
Define and value of a nuclear reaction?
Well, a nuclear reaction is where atoms are bouncing around and collide. They brake down into smaller or equal sized particles and this gives off fairly high amounts of energy. Just wiki it if you want a professional answer...
Is fire example of nuclear energy?
No. Fire is a chemical reaction, oxidation actually, just a very fast form.
What are the names of the particles involve in a nuclear reaction?
If we are just considering the "basic" nuclear reaction in a "regular" nuclear reactor, the particles of interest are the uranium-235 atoms (which are fissionable), and the neutrons, which get loose and cause fissions when they are absorbed by the U-235 atoms. We could broaden this to include some other reactions, but this is a fabulous place to begin to investigate nuclear physics.
How is a chain reactor controlled?
Since the continued chain reaction of a nuclear fission reactor depends upon at least one neutron from each fission being absorbed by another fissionable nucleus, the reaction can be controlled by using control rods of material which absorbs neutrons. Cadmium and boron are strong neutron absorbers and are the most common materials used in control rods. A typical neutron absorption reaction in boron is In the operation of a nuclear reactor, fuel assemblies are put into place and then the control rods are slowly lifted until a chain reaction can just be sustained. As the reaction proceeds, the number of uranium-235 nuclei decreases and fission by- products which absorb neutrons build up. To keep the chain reaction going, the control rods must be withdrawn further. At some point, the chain reaction cannot be maintained and the fuel must be replenished
What is the difference between nuclear and steam and hydroelectric power plants?
These are things that are not comparable. Nuclear power refers to the fuel, just as natural gas, coal, or oil would. Steam refers to how the fuel is used, and the fuel might be natural gas, coal, oil, or nuclear; an alternative to steam would be to use natural gas or oil to power a turbine directly.
