tja .. 9-11 had heel goed anders gekund idd
ook best stom van die kapers dat ze 'wel een boeing kunnen besturen' maar niet een kerncentrale waar ze overheen vliegen herkennen (als doel)
iig .. een perfecte veiligheid kan er imo niet over geboden worden en er zullen best verbeteringen zijn gemaakt... ondanks dat is het totaal van de bijna 500 plants toch een flinke bult afval
en daarin zit relatief meer 'nauwelijks schadelijk' afval in dan dat er zwaar afval in zit wat een takke lange tijd niet echt gezond is
Nuclear Waste
ene site
The majority of high level radioactive waste produced comes from the fuel in the core of nuclear power reactors. Irradiated fuel is the most radioactive fuel on the planet and accounts for some 95% of radioactivity generated in the last 50 years from all sources, including nuclear weapons production. Once removed from the core, irradiated fuel is stored in cooling pools on the nuclear reactor site. Each 1000 megawatt nuclear power plant produces about 500 pounds of plutonium a year and about 30 metric tons of high-level radioactive waste.

High energy means a small volume of used fuel. Every 12-24 months, U.S. plants are shut down and the oldest fuel assemblies are removed and replaced. All of the country's nuclear power plants together produce about 2,000 metric tons of used fuel annually. To put this in perspective, all the used fuel produced to date by the U.S. nuclear energy industry in more than 40 years of operation—some 40,000 metric tons—would cover an area the size of a football field to a depth of about five yards, if the fuel assemblies were stacked side by side and laid end to end.

Anti-nuclear activists like to scare us with horror stories about the "thousands of tons of nuclear waste" that have been produced since nuclear power began some four decades ago. That sounds like a lot -- until you put it into perspective, which anti-nuclear activists and the mass media never do. Consider that one pound of plutonium can produce as much energy as the Yankee Stadium full of coal. And coal-fired power generates something like a billion tons of waste annually in the United States, or about 30 tons of ash per second. In a few hours, more coal ash is generated than high-level nuclear waste has been generated in four decades!
conclusie
het is allemaal slecht ..
het ene is erger maar heeft minder volume en het is anders slecht
