Stockpiles of rocks containing uranium ore sit in an outdoor storage area at the Rozna uranium mine, operated by Geam, a division of Diamo S.P. mining company, in Dolni Rozinka, Czech Republic, on Thursday, April 10, 2014. Prices of uranium are forecast to climb more than 40 percent by the end of the year as Japanese power plants restart nuclear reactors that have been shut down since the March 2011 earthquake and tsunami in Fukushima.
