IThEO.org Supermiljöbloggen Reactor Thorium reactors would be cheap. The primary cost in nuclear reactors traditionally is the huge safety requirements. Regarding meltdown in a thorium reactor, Rubbia writes, “Both the EA and MF can be effectively protected against military diversions and exhibit an extreme robustness against any conceivable accident, always with benign consequences. In particular the [beta]-decay heat is comparable in both cases and such that it can be passively dissipated in the environment, thus eliminating the risks of “melt-down”. Thorium reactors can breed uranium-233, which can theoretically be used for nuclear weapons. Like any nuclear reactor, thorium reactors will be hot and radioactive, necessitating shielding. Because thorium reactors present no proliferation risk, and because they solve the safety problems associated with earlier reactors, they will be able to use reasonable rather than obsessive standards for security and reliability. Even smaller reactors might be built.
Liquid Fluoride Thorium Reactors An old idea in nuclear power gets reexamined Robert Hargraves, Ralph Moir When the United States committed decades ago to uranium fuel and pressurized-water reactors for its nuclear program, other viable technologies were set aside.

New age nuclear Credit: Justin Randall What if we could build a nuclear reactor that offered no possibility of a meltdown, generated its power inexpensively, created no weapons-grade by-products, and burnt up existing high-level waste as well as old nuclear weapon stockpiles? And what if the waste produced by such a reactor was radioactive for a mere few hundred years rather than tens of thousands? Named after Thor, the warlike Norse god of thunder, thorium could ironically prove a potent instrument of peace as well as a tool to soothe the world’s changing climate. But nuclear power comes with its own challenges. A thorium reactor is different. BY THE END OF this century, the average surface temperature across the globe will have risen by at least 1.4˚C, and perhaps as much as 5.8˚C, according to the United Nations Intergovernmental Panel on Climate Change. That may not sound like much, but small changes in the global average can mask more dramatic localised disruptions in climate. According to the U.S.
Peak Oil and the Financial Crisis: Where do Oil Prices Fit In? at Oil Price The Financial Times and Wall Street Journal have gone into full crisis mode with live blogs continuously reporting unfolding events. Equity markets are falling and London oil prices have been flirting with $100 a barrel for the first time since February. Talk of recessions, depressions, and even collapse of the euro zone is everywhere. There seems to be general agreement that a Greek debt default is inevitable. Select the reports you are interested in:NO-SPAM: Under no circumstances will we EVER rent, sell or give away your email There is growing concern that defaults in Europe would quickly engulf Wall Street financial institutions and that even the great Chinese growth engine could be hurt seriously by declining exports. Even though NY oil prices have fallen by some $38 a barrel since peaking in April, gasoline and diesel in the US are still retailing for 70-80 cents a gallon more than last year. The last great depression lasted for a decade and was only ended by World War II. By.
Höga halter av bisfenol A i svenska kassakvitton Höga halter av det hormonstörande ämnet bisfenol A har uppmätts i svenska kvitton. Halterna var 1000 gånger högre än i de nappflaskor som förbjudits i flera länder visar en ny svensk studie. Typ av kvitton och bisfenolinnehåll. Kassakvittot blir svart på någon sekund när det värms över en låga. - Jag blev förvånad över att halterna var så höga, säger miljökemisten Tomas Östberg vid Jegreliusinsititutet vid Jämtlands läns landsting och en av författarna till studien. Fyra familjer fick under två månader spara alla sina kvitton som sedan analyserades. Studien kompletterades med parkeringsbiljetter, fruktdisketiketter, kölappar, uttagskvitton och olika biljetter. Allra högst var halterna i parkeringsbiljetter och busskvitton. - Framförallt kassapersonal exponeras för bisfenol A. Forskarna kunde också konstatera att ämnet lossnar från kvittona och sprids. Det är så kallade termopapper som innehåller bisfenol A. Ämnet är vanligt och används som tillsatsämne i polykarbonatplast.
