What else can I help you with?
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.
Is uranium on the sun?
Yes, uranium is present on the sun, but in very small amounts compared to other elements. Uranium is created through nuclear fusion reactions in stars like the sun, but it is not a major component of the sun's composition.
What are the major indicators of a global problem?
the major indicators of a global problem are it affects earth and all it's people. The problem is interconnected and very complex. The solution requires several nations to help solve or resolve. The consequences are universal. The problem is greatly impacted or affected by our attitudes towards it. Solving a global problem requires involvement of several different people from several nations.That was 5 examples of the major indicators of a global problem
A major problem caused by humans is the contamination and depletion of resources.?
Water.
What is the unsolved problem of nuclear energy?
One of the unsolved problems of nuclear energy is the issue of long-term storage and disposal of radioactive waste. Finding a safe and sustainable solution for the disposal of nuclear waste, which remains hazardous for thousands of years, is a major challenge facing the nuclear energy industry.
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
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.

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 is a problem caused by using nuclear energy?
There are arguments about where to store the waste. (APEX)
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.

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 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.
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.
