At current usage, it's estimated that there are around 35 million tons of uranium in Earth's crust; enough to power human civilization for over 2,000 years, or to build millions of nuclear warheads.

在当前情况下，据估计地球上大概含有3500万吨的；这足够提供给人类文明供电超过两千年，或者只是造几百万个核弹头而已。

Rafael Grossi began meetings in Tehran on Friday that diplomats said were meant to push Iran to cooperate with an IAEA investigation into uranium traces found at undeclared sites that had been enriched close to nuclear-weapons grade.
