Bezpecne jadrove elektrarne mi pridu ako oxymoron (najma po Fukushime).

Preco jadrove reaktory a nie obnovitelne zdroje energie ako mala biomasa, male vodne elektrarne a solarne panely na strechach budov? Kam s jadrovym odpadom? Preco byt zavisly od dovozu uranu? Preco investovat do zariadeni, ktore nemozno vymenit rentabilne najblizsich 50-60 rokov?

Akurat citam, ze veterna energia je lacnejsia ako plyn, jadro a uhlie, ak sa zapocitaju externality: http://www.theguardian.com/environment/2014/oct/13/wind-power-is-cheapest-energy-unpublished-eu-analysis-finds?CMP=EMCENVEML1631

tak skusim copy-paste z clanku:

Lockheed estimates that less than 25 kg (55 lb.) of fuel would be required to run an entire year of operations. The fuel itself is also plentiful. Deuterium is produced from sea water and is therefore considered unlimited, while tritium is “bred” from lithium. “We already mine enough lithium to supply a worldwide fleet of reactors, so with tritium you never have too much built up, and that’s what keeps it safe. Tritium would be a health risk if there were enough released, but it is safe enough in small quantities. You don’t need very much to run a reactor because it is a million times more powerful than a chemical reaction,” McGuire notes.

Although the first-generation reactors will have radioactive parts at the ends of their lives, such as some steel elements in the shell, McGuire says the contamination situation “is an order of magnitude better” than that of contemporary fission systems. “There is no long-lived radiation. Fission reactors’ stuff will be there forever, but with fusion materials, after 100 years then you are good.” Contamination levels for fusion will improve with additional materials research, he believes.
