President Donald Trump signed four executive orders to overhaul the Nuclear Regulatory Commission and hasten the process and deployment of new nuclear power reactors in the United States.

Shares in companies tied to nuclear power jumped Friday, helped by President Donald Trump’s rollout of four executive orders that aim to provide a boost to the sector, but there were concerns about whether there could be much of a near-term impact.

Donald Trump’s draft executive order pushes a nuclear strategy focused on deregulation and deployment, but lacks solutions for financing and global partnerships. The Trump administration has correctly identified Russia and China as the main impediments to its goal of dominating global nuclear energy in the twenty-first century.
