Seth Grae, CEO of Lightbridge (LTBR), returns to Market on Close while speaking to senators in Washington D.C. He says there's plenty of support for nuclear power on Capitol Hill as he emphasizes the importance of expanding usage, particularly through icebreaker ships as a way to combat China and Russia dominance in the Arctic Ocean. On President Trump's executive order to increase nuclear power output, Seth believes Lightbridge technology will boost efficiency on new and existing reactors.
