1. After 50 years the US still has no repository for dangerous nuclear waste.
2. Nuclear power in the world is the cover for nuclear proliferation.
3. The effects of a possible nuclear accident are so horrific they can't be insured by the free market requiring government subsidy of insurance.
4. Nuclear plants require large amounts of fresh water and generate considerable thermal pollution in the rivers they use for cooling.
1) The issue of nuclear waste is something that needs to be solved - I fully agree. However, it produces relatively small amounts of waste, and it's definately not dangerous like you claim it to be.
When we transport the waste for storage, we don't do it haphazardly. They are carried in caskets layered with multiple walls of concrete, only penetrable by anti-tank artillery. Plus, it's cooled for years, so that the decay heat and radioactivity are considerably reduced. It's not flammable - it cannot explode - even if the casket was broken by a terrorist attack, the waste would fall onto the ground and spread harmless amounts of radioactivity.
2) Nuclear power requires around 3-4% enrichment of U235. Nuclear weapons require much more enrichment (I believe it's in the 90%s) to be effective. HUGE difference.
3) You
do realize we're talking about nuclear reactors in the U.S. right, not the types used elsewhere (like Chernobyl). I would like to know your reasoning for how a terrible disaster could occur in the U.S.
In the RBMK reactors (like Chernobyl), they use water to cool their process down by removing some of the slow neutrons. This prevents the reactions from growing exponentially. Of course, there's the risk of not having enough water (or letting too much evaporate) and having terrible consequences. Also, once air entered the core, it reacted with the graphite (which they used as a moderator - we use water), forming carbon monoxide and catching fire.
The LWRs, on the other hand, require water to be used as a moderator, meaning that it is fairly self-stabilizing. If the core overheats, the water disappears, and the fission reactions stop occuring. Of course, you can still have problems (3 Mile Island), but not nearly as bad as what happened in Chernobyl.
Oh yes, and
there weren't any long-term radiation effects, either. And Chernobyl had less containment for their reactors than we do in America (because they wanted the plutonium byproduct for military purposes). Also, you have to look at it in comparison with other forms of energy:
Code:
Fuel | Fatalities (1970-1992) | Deaths per tW/y of electricity
------------+------------------------+--------------------------------
Coal | 6400 | 342
Natural Gas | 1200 | 85
Hydro | 4000 | 883
Nuclear | 31 | 8

4) I'd love to see some numbers and evidence on how bad this problem really is.
It looks like nuclear power is getting support from some
surprising places, too. And it may have
some hope yet.
Oh yeah, and all of the information I've learned is simply from private research, so I could easily be wrong on some (many) things. Like always, double-check everything.
