I'm against fission based nuclear power plants. Fusion based aren't ready for large-scale production of energy, so I'll not discuss them for now.
I'll reply to the points in Deagonx 1st post.
1. That is not a good argument in favour, saying that the arguments against aren't good.
2. Under ideal conditions, the pollution of a nuclear plant is acceptable, the problem is that nobody can guarantee ideal conditions all the time. Accidents happen and we can't predict the next human error. On top of that, the Universe is beyond our control: earthquakes, hurricanes, floods, asteroids, etc..
3. True. But that "small to moderate dose of radiation" means in fact a very low value. A nuclear plant has inside values much much much higher than those. And the Nature gives us a small dose of radiation, so we don't really need more, do we?
4. Is very well answered by Duckling. To get the Uranium you'll to mine it. Mining affects the landscape (the presence of roads, to say the least). If you want a more drastic effect, the water near the mines is usually contaminated with solvents.
5. Again, very well answered by Duckling. No change of energy source needs to be drastic. If things are well planned, the transition can be smooth.
6. I don't agree totally. The number of incidents is indeed very low, but when problems arise the consequences are very serious.
So, in favour of using nuclear energy:
8. It's a very efficient source of energy.
9. It can reduce the production of greenhouse gases if it's used to replace fossil fuels.
10. Today there aren't alternatives available in a large scale to replace both fossil fuels and nuclear power.
And against:
11. Accidents are usually very serious.
12. Costs of proper disposal and treatment of radioactive waste and cleaning affected areas aren't included in the cost of operation of a nuclear plant, rising it's cost a lot when these accounted for.
13. "Clean" alternatives exist and their cost is getting lower. So, when deciding we must also think one step ahead.
For me, point 11 is the major one. Nuclear plants should be gradually shut down. And investment in solar power should be significantly increased (solar energy used for heating water, for illumination and for producing electricity). Increasing efficiency of energy use should also be made.
