Transatomic Power reduced their claims of nuclear fuel efficiency

In a white paper published in March 2014, Transatomic Power proclaimed its molten salt reactor “can generate up to 75 times more electricity per ton of mined uranium than a light-water reactor.”

In a paper on its site dated November 2016, the company downgraded “75 times” to “more than twice.” In addition, it now specifies that the design “does not reduce existing stockpiles of spent nuclear fuel,” or use them as its fuel source. The promise of recycling nuclear waste, which poses tricky storage and proliferation challenges, was a key initial promise of the company that captured considerable attention.
