They're unquestionably better than coal as far as environmental effects, assuming they're run well and protected from terrorists, etc. Coal plants are awful, especially the older ones.

I think they require more government subsidies than some renewables (i.e. wind), but part of that is probably regulation and siting. Then again, some of the regulation is quite necessary--I can easily believe some of it isn't but I've no idea what the % is--and I'd be a bit uneasy living near one myself.

I'm not necessarily opposed to more nuclear power as a supplement to conservation and renewables, but we're doing so little of the latter that right now that increased nuclear subsidies would be instead of renewables* and conservation, not a supplement.

I took an environmental engineering class in college, and this is how he ranked power sources in their environmental impact, from worst to best. (disclaimer: circa 1999--the technology may have changed, my prof may be weird, and I may be mis-remembering):

HIGH IMPACT
poorly-run nuclear
coal
hydroelectric (but most of the damage is done when the dam is first built; once it is, it's often best to keep it operating)

MEDIUM IMPACT
well-run nuclear
biomass (i.e. wood)
oil
solar (some heavy metals in the cells)

LOW IMPACT
natural gas
wind

most people would move solar below natural gas now, owing to increased concern about CO2 emissions & improved design of the solar cells. And I forget where things like geothermal and tidal and other more obscure or location-specific renewables went, but they were definitely in the low impact category. Ditto for fuel cells.

*uranium is not renewable, says the EPA.

Moe, I'm always amused when VWRC-ers are surprised that mainline Democrats are moderately in favor of nuclear power. We've just got a few preconditions:

1) no government subsidy
2) tough regulations to maintain reliability and confidence, both.
3) prove that you can dispose of the crap in a reasonably responsible way
4) get over the idiotic resistance (on the left!) to recycling nuclear waste. It's gotta be done. The current model is to use some 5%-10% of available fissionable material.

Apparently, there's some very hopeful research in steam-regulated nuclear power at
Ceasar (U Maryland)

Looking back, the effective moratorium on nuclear power construction isn't the worst thing to happen. Let the French and the Russians make the mistakes and trials & errors. Now we can get it right the 3rd time around.

"Moe, I'm always amused when VWRC-ers are surprised that mainline Democrats are moderately in favor of nuclear power."

Fair enough. :)

PS: Your point on getting it right the third time around is an interesting one, but I dunno that it was the optimal solution...
