About seventy years.
The useful life of a nuclear fission reactor is typically around 40-60 years. However, this can vary depending on factors such as maintenance, upgrades, and regulatory approvals.
In nuclear reactors used to generate electricity, and in many nuclear warheads.
Uranium-235
With fission reactors, probably at least a hundred years. By then fusion may be usable and this will last indefinitely, as so much deuterium is in the oceans.
The use of Nuclear Fission has many drawbacks. 1) is the chance of a Nuclear Meltdown which can leak a lot of radiation, which can cause horrible illnesses such as cancer. 2) It costs a lot of money to decommission a nuclear power plant. 3) The waste nuclear fission creates can be unstable if not kept at a cool temp. I hope this helped
Nuclear fission is a type of nuclear reaction: the nucleus of an atom is broken in two parts (and many other fragments).Plutonium wastes are wastes containing plutonium.
In principle fusion should be better for the environment because it does not produce the active fission products. The snag is that it has not been made to work yet, and won't be for many years to come, so as a practical way of producing electricity it does not come into play, and we have to say fission is better than a non-existent fusion
In general, nuclear energy comes from the energy associated with atomic nuclei. There is nuclear fusion, which happens in stars and in fusion weapons, and there is nuclear fission. Nuclear fusion is the "combining" of lighter atomic nuclei to create heavier ones, and many fusion reactions release energy. (Again, think of stars.) In contrast, nuclear fission is the "splitting" of atomic nuclei to release energy. The latter is technology that we've come to use fairly widely, and we have developed fission nuclear weapons and the nuclear reactor to tap nuclear energy via fission. Let's look at the latter device, the reactor. The fission of nuclear fuel (also known as atomic fuel, such as uranium or plutonium) is where we get nuclear energy. And what happens during nuclear fission is that the nuclei of fuel atoms absorb neutrons and fission (split), releasing lots of energy. In fission, that larger atomic nucleus breaks into a pair of smaller ones, and these fission fragments recoil with a lot of kinetic energy. The fuel traps the fission fragments, and the energy they came away with is converted into thermal energy in the fuel. We derive nuclear energy by tapping the energy of formation of atomic nuclei via fusion or fission. This is advanced technology that is less than a century old. We're still working to use it well and wisely.
The nuclear fission process produces a range of lighter elements as fission products, and many of these are radioactive.
if the fission was of uranium, then yes. but many transuranic elements (e.g. plutonium, americium) also fission.
Many nuclear power stations in different countries-mainly the US, UK, France, Canada, Russia, and others.
If you mean a nuclear reactor, and not a chemical one, there is only one way, and that is by nuclear fission in the fuel
