Compared to everything else we have currently? Yeah. But there's a lot of hysterics and bad information out there. So, here you go:
The uranium which powers a nuclear reactor has a long enough half-life (the rate at which the atom decays, which is the measure of its radioactivity) is long enough that you can safely hold the pellets in your bare hands for 80+ years before there is a statistically noticeable (not even significant, just noticeable) increase in the rate of radiation poisoning. You receive more radiation in a single x-ray at the hospital. Not only that, a single plant is able to produce more energy than 40 traditional coal burning plants.
Now, it is important to understand how nuclear power is generated to really understand why its safe.
Pellets of Uranium are essentially submerged in water and as the uranium decays, it heats the water and turns it into steam. The steam turns a turbine and this spins, generating electricity.
That's really all there is to it. The only byproducts are steam (which is not radioactive) and spent uranium. Its cheap, effective and lasts a long time.
In theory.
In practice, there are, to be a fair, potential hazards.
1) nuclear waste: while the waste is actually more stable (and therefor less dangerous) than the raw uranium, nobody wants to take the risk. And, of course the more radioactive material in an area, the more likely to experience radiation poisoning.
2) out-dated reactors: If the reactors aren't maintained (as was the case at chernoble), there is potential for a "melt-down" where pressure builds up in the containers and they can potentially explode. This can, potentially, release radioactive material into the air. However, it needs to be remembered that nuclear material is very heavy when compared to most airborne particles, so it doesn't travel very far. And, even if the reactor explodes, it will not be a NUCLEAR explosion; there is no mushroom cloud. The conditions required for a nuclear explosion, as seen with nuclear weapons requires VERY specific and controlled conditions for the chain reaction to start and requires a less stable form of radioactive material than is found in reactors.
3) The uranium has to be mined: like coal, there are always side-effects from mining. However, uranium is not consumed as quickly as coal and generates more energy per pound.
4) Before it can be used in a reactor, most uranium has to be refined. This is a chemical process and again results in by-products.
So how does nuclear really stack up?
It IS cheaper, more effective and significantly less polluting than any other fossil fuel.
Nuclear IS more cost effective and generates more energy than solar/wind/water/geothermal and requires less in terms of maintenance (geothermal turbines, for instance, are extremely expensive to maintain)
Nuclear energy is pretty safe: You get more harmful radiation in a single day from solar and man-made sources than you get from radioactive materials
Nuclear energy is clean. It is the cleanest source of energy we have.
what is a better source nuclear or solar energy.
Nuclear Energy.
Nuclear power is very good source of energy to turn to. The only problem is the storage of nuclear waste, that is left over after the nuclear reaction the power plant. The energy obtained from the nuclear power plant is very clean burning and more KJ/mole energy.
No, nuclear power is a decent source of energy, depending upon the reactor design and siting. Locating reactors over fault lines or near ocean shore lines seems unwise.
Nuclear energy is clean. It is the cleanest source of energy we have.
The nuclear energy is now the most important source of alternative energy.
Nuclear energy is a very clean source of electricity. There are no pollutants put into the air, and it is very efficient.
While there are no electricity sources that are one hundred percent clean for the environment, nuclear energy is close to the top of best energy sources. While nuclear energy will give a radioactive material, there are no dangerous air emissions, because nuclear energy gives off steam.
A nuclear fusion reaction could produce a virtually limitless and clean source of energy. This occurs when two light atomic nuclei fuse to form a heavier nucleus. This releases a large amount of energy.
what is a better source nuclear or solar energy.
The kWh produced by nuclear energy is the cheapest. It is a clean energy that does not pollute the environment. It gives chance for people to work during its construction and operation. It is reliable source of energy.

It is the source of the sun's energy
Nuclear Energy.
Because it is a very clean source of energy that is very powerfull
