Is the nuclear reaction that takes place in a nuclear electrical generating plant exothermic?
I would imagine it is since the goal of an electric plant is to give off energy, and exothermic reactions release entergy. Both fusion and fission, the two major nuclear reactions, are exothermic.
How is nuclear fission like a chain reaction?
One large nucleus, typically uranium, undergoes fission and releases several neutrons along with the major fission products. These neutrons strike more uranium atoms and are absorbed by the nucleus causing it to become unstable. It undergoes fission releasing more neutrons and more fission products. These neutrons strike more uranium atoms etc.

How does URANIUM contribute to the ecomomy of the US?
Uranium is the major component of the nuclear fuel in the nuclear energetic reactors. Also United States use uranium for weapons.
What is a major disadvantage of using nuclear fusion reactors?
Today these installations are not surely controlled.
What are the problems faced by the use of nuclear fission in physical reaction?
The main problem with nuclear fission is the high level nuclear waste formed in the fuel. This is extremely dangerous and has to be kept in a safe shielded place for centuries after the fuel is discharged. This is achievable but it will need awareness of the problem in many future generations of the human race and the maintenance of whatever repository is used, even if this type of energy source has been discontinued and largely forgotten.Needless to say, during operation of the plant this radioactive material must never be allowed to leak from the reactor boundary into the surroundings, and this is one of the major preoccupations of reactor designers and operators.
Why nuclear ways said to be a problem to difficult to solve?
a nuclear wastes is one of the major problem that we are facing now because it is harmful to our environment,to people as well as in our health
Are some nuclear wastes stored for centuries to prevent dangerous radioactivity from escaping?
Yes. Some radioactive waste, like spent nuclear fuel, remains highly radioactive for thousands of years. Attempts were made to reprocess the spent fuel, but it is extremely dangerous and it is not very cost effective in many cases to do so. There are other forms of radioactive waste generated every day, but we work at being careful about what we generate to avoid having to store it. But the problem with nuclear fuel is a major one. Spent fuel is far and away the major contributor to high level radioactive waste in the world. Consider that 235U and 239Pu are the most common nuclear fuels. When they fission, they leave behind fission products. (The atom of fissile material "split in two" and there are a pair of fission fragments. Different pairs of fragments are possible.) With either fuel, there are over a dozen fission products from the fission process that have a half-life measured in thousands of years. There are a lot of fission products in the spent fuel, they are highly radioactive, and the remain highly radioactive for thousands of years after use. We can't just throw them away.

What are the risks associated with the use of nuclear energy?
The major risk is the only bi products which are capable of radiating harmful radiations such as gamma rays and emitting alpha and beta particles. Otherwise it will be a great boon for the humanity to produce electrical power in a cheaper way. In case of nuclear fusion such a problem does not exist but the pity is that for initiation we need the nuclear fission to produce the high temperature needed for fusion reaction to get started.
Major drawback to the use of nuclear power?
A major drawback to the use of nuclear power is that it produces radioactive waste. This waste can pollute water sources and kill organisms.
What is the origin of nuclear energy?
There are two major types of nuclear energy, fusion and fission. Fusion comes from hydrogen nuclei sticking together in the hearts of stars, which liberates energy. Fission energy comes from the splitting of heavy nuclei. A third type of nuclear energy comes from the slow decay of unstable isotopes, most generally through the release of alpha or beta particles. Both of these are the result of a transmutation of the isotope. Fissionable isotopes are produced naturally in supernova.

What is P versus NP. The solution?
The P versus NP problem is a major unsolved problem in computer science. Informally speaking, it asks whether every problem whose solution can be quickly verified by a computer can also be quickly solved by a computer.The first mention of the underlying problem occurred in a 1956 letter written by Kurt Gödel to John von Neumann.
Is there any possibility of water being used as a fuel if yes how?
One of the big ideas being toyed with at the moment is nuclear fusion. Currently energy is produced in nuclear powerstations by a process called fission in which nucli are split. The problem with this is that all sorts of very dangerous toxic and radioactive substances are produced. Nuclear fission releases energy when the nuclei are heavier than iron. In nuclear fusion two nuclei are joined together to release energy, this works with nuclei lighter than iron. Hydrogen is the lightest of all nuclei and so has great potential for nuclear fusion. Water is made up of two hydrogen atoms and an oxygen atom and there is lots of it. The hydrogen can be removed from the oxygen using a process called electrolysis where an electric current splits it up, the hydrogen could then be fused to produce energy for whatever you want to power and for the electrolysis. The major problem with nuclear fusion is that we can currently only get it to work at very high pressures/temperatures. This is because nuclei have a positive charge and so repell each other. To get them ot fuse you need to get them so close that the strong nuclear force takes over.
What is the problem with storing nuclear waste material?
The challenge of making nuclear power safer doesn't end after the power has been generated. Nuclear fuel remains dangerously radioactive for thousands of years after it is no longer useful in a commercial reactor. The resulting waste disposal problem has become a major challenge for policymakers.
