Alvin Weinberg, then the director of Oak Ridge National Laboratory, marks 6000 power hours performance of his brainchild, the Molten Salt Reactor Experiment, in October 1967.

The Molten Salt Reactor Experiment (MSRE), which ran a brief four years in the 1960s but earned an enduring legacy as an innovative reactor technology concept, this year marks a half century since its June 1965 startup. A workshop on molten salt reactor technologies, "From the ...

Thawing permafrost and contaminated sediment in marine coastal areas pose some of the greatest risks for the production of highly toxic methylmercury, according to findings published in the journal Science Advances. The discovery of these newly identified location...
