Any nuclear fission reactor contains very dangerous radioactive material after it has been operating for a time. These are mainly the fission products, and hence are contained in the partly used up fuel. You will have seen the result of the accident at Chernobyl, where a lot of this was released to the atmosphere.
The processes of designing and operating the plant safely must ensure that this does not happen.
1. The fuel cladding must not be damaged by melting or any other form of damage in any conceivable fault.
2. The cooling medium of the reactor (water/steam or gas) must not be released in an uncontrolled way.
3. The reactor must always be able to be shutdown safely and held down.
The skill of the designers and operators is what makes a potentially dangerous plant safe to operate.
The main risks associated with nuclear power include the possibility of accidents such as meltdowns, the generation of radioactive waste that needs careful disposal, and the potential for nuclear weapons proliferation. Additionally, there are concerns about the high costs of building and maintaining nuclear power plants.
There are two types of nuclear power plants: fusion and fission reactors. Fusion reactors are not yet used in power plants. If a FUSION reactor is operated continuously and the magnetic plasma containment would fail, the reaction would simply stop. If I remember correctly, during a visit to the JET some years ago (in Oxfordshire, UK), it was explained to me that the only "dangerous" side effect from fusion power in the current tokamak reactors is that the inner shielding (which I believe is carbon) becomes radioactive itself due to the bombardment by neutrons. This leaves some radioactive waste, just like with fission reactors, but less. Aside from the waste, FISSION reactors are not completely fail-safe. Once ongoing a fission reaction keeps itself going, until the reaction is interrupted. If this interruption does not occur and/or the reactor is not cooled enough, the core could melt , releasing its contents into the atmosphere (see Nuclear Meltdown on wikipedia). Notes: 1. Neither fusion nor fission reactors can cause a nuclear explosion. A nuclear explosion requires specific components and conditions which are not present in these reactors. 2. A fusion reactor does not need radioactive fuel, nor are its reaction products radioactive. A fission reactor does need radioactive fuel, and a siginificant amount of its products are radioactive as well.
First all nuclear power is cheap and efficient thats why we are now relying on nuclear power
But the most dangerous process of power gwneration is this,we are using nuclear fission in reacters,so the uranium nucleus by hitting of neutrin split into plutonium(another radio active material) and neutrons,this neutron will hit other like the chain reaction is continues,we are using cadmium rodes in reacters to control it,the reacter temperature reaches to high as surface of sun,and by this we vaporise water and makes energy
1)if cooling sytem went wrong the reaction will become un controllable and nuclear plant may explod,it will result in massive nuclear radiation
2)natural disasters like tsunami,earth quakes etc may case high damages to the(like fukushima)
3)nuclear waste is highly radio active,so we cannot throw it away like other waste,we have to make undeground storages or seal the inside container and dip in sea
4)the water from powerstation will reach sea,which result in temperature increase in sea,so it may effect the ecosystem of sea
Nuclear Power, although clean (to the extent), produces a large amount of power. A Nuclear Power Plant may have a meltdown if not treated properly meaning if it overheats or something happens like the Chernobyl accident. Another is what to do with the nuclear waste that come out after the fuel rods have wasted themselves out. The waste can be sent to an underground bunker somewhere in the West of America. (I don't know the precise location) but there is always the risk of it leaking into the environment and killing many organisms.
well.....nuclear fission is very dangerous
You could die from the radiation, have a problem and cause an explosion (like the Chernobyl accident) or even forget some important step in controlling the energy.
it may cause diseases related to skin
Nuclear power can be a good alternative energy source as it produces low greenhouse gas emissions and provides a reliable source of electricity. However, there are concerns about nuclear waste disposal, the risk of accidents, and high costs associated with building and maintaining nuclear power plants.
Electricity, but there is a risk of radioactive leakage.
The main problems with nuclear power include the potential for accidents such as meltdowns, the production of radioactive waste that needs to be safely stored for thousands of years, the high cost of constructing and decommissioning nuclear plants, and the risk of nuclear proliferation and nuclear terrorism.
Some disadvantages of nuclear power include the risk of accidents leading to radiation leaks, the long-term storage of radioactive waste, the high costs of building and maintaining nuclear power plants, and concerns about nuclear proliferation and security risks.
it may cause diseases related to skin
The main risk associated with using nuclear fission for energy production is the possibility of a nuclear meltdown, which can release harmful radiation into the environment. Additionally, there is a risk of accidents, such as human error or equipment failure, that can lead to serious consequences. Proper safety measures and regulations are necessary to mitigate these risks.

The waste is the issue.
The same reason as the other countries that have nuclear power plans. Firstly to show off power. The other reason : Fear. Not even for energy generation, nuclear capability is justified due to the high risk that nuclear power plants represent.
Outer Electrons are not associated with nuclear reactions.
