Why do all current power plants fission reactors?
If you mean why are all current nuclear power plants fission reactors, this is simply because the creation and control of nuclear fusion reactions on a scale and level suitable for commercial purposes are not currently well-understood. Experimental reactors can create and hold a plasma for a short period, and sometimes realise a small net gaing in energy, but none currently can run for an extended period. They are also technical challenges remaining around containment of the plasma and degradation of the plasma vessel due to neutron damage. The current wisdom among fusion researchers is that "commercial fusion power has been 50 years away for the last 50 years...."
Which is more important nuclear energy or atomic energy?
Nothing really, nuclear bombs have more blast than atomic.
Give the characteristic of nuclear force?
The characteristic of a nuclear force is that it is only felt among hadrons and is stronger than the Coulomb force at short distances.
What affects does nuclear energy have on natural resources?
The natural resource of nuclear energy is uranium. Uranium is abundant everywhere on earth. However, the cost of its extraction is the limiting factor for the feasibility of any uranium resource. Among the countries with high uranium resources are Australia, Canada, Kazakhstan, Niger, Chad, and South Africa.
What type of nuclear reaction is used n power plants?
Most nuclear power stations have pressurized water thermonuclear reactors. The nuclear reactions that take place in these reactors are fission (atom splitting) and nuclear decay. (Let's not split hairs so we can concentrate on splitting atoms.) In simple terms, these reactors work by fission of enriched uranium, which is uranium with a higher-than-natural amount of the U235 isotope. This isotope has a higher probability of capturing a neutron and splitting than other stuff. That's the fission part. After the uranium splits, neutrons are released and these can be used to make more fissions if they are slowed (thermalized). Links to Wikipedia are provided. There must be some consideration given to the fission products. These are the "broken pieces" left after an atom splits. There are a fair number of these and they continue to decay. Their half lives and decay schemes vary, and an interested party would review the Wikipedia article to get the low down on them. A link is provided.
What can we design to stop industrial pollution?
Fast neutron nuclear reactors, among other new Nuclear technologies. Nuclear power is the cleanest most efficient power source. Reducing burning of fossil fuels will significantly reduce pollution in the atmosphere.
Will Osaka become the new capital city of Japan following the nuclear meltdown?
According to some sources among the diplomats, this is a likely scenario.
A neutron is an unstable particle outside a nucleus but to start nuclear fission requires the slowing down of a neutron. How is nuclear fusion carried out in the case of uranium?
The neutrons released from Uranium are fast neutrons. In a reactor they are slowed down by a moderator. The moderator could be water, heavy water, graphite, among others. When the neutron is slowed down, it is more likely to create fission.This is what happens with the U-235. The U-238 does not fission, but it does transmute through a series of neutron absorption and beta decay etc. into plutonium which does fission also.
