Hi Joe, Brian, EnviroNet Listservers, Joe, I really don't know much about the environmental effects, or the global energy effiency of Nuclear Power plants. I have seen a little here and there over the years you, Brian, I, and others have lived on this earth yet not a lot that has fully informed me about this energy option. I know the French like it, and some others in the EU don't like this option. Every country's resources is a bit different. I will read Brian's notes again so I will learn a bit more on one side of the equation (the supply side), not the disposal side. SO Anyway, Nuclear Power has a bad rap based on Nuclear and "A" bombs used in warfare and "sloppy management" of Nuclear Power facilities like in the Ukraine. In Japan even though a Nuclear Power plant was more immune to earth quakes then the rest of their infrastructure the Japanese citizenry made a major power plant close. They probably were afraid of another home grown Hiroshima. Again it seems like fear is the prime motivator against Nuclear Power on one side of the table. On the other side (Iran) it seems like Nuclear Power is either a "we want to be one of the big boys" or they really need Nuclear Power so that they can sell and make an income out of their land resources.
