The US and Chile have signed a longed-for nuclear deal despite growing concerns in Chile over the dangers from nuclear power. The government of Chile says that the contract is not about building a nuclear reactor but training nuclear scientists. However, it came amid worries over a radiation crisis at Japan’s Fukushima nuclear plant after the devastating earthquake last week. Chile had also suffered a huge quake last year. Chile’s environmental groups have condemned the decision to invest more in nuclear power as other nations are cutting back spending on their nuclear projects.
