He leaves completely open how the US electricity market would replace the missing nuclear energy. For all we know, he might expect the US to crank up their gas power plants. I fail to see how this is a win for nuclear energy. Also, it's an US-centric article and as it's states, the US only has a 15% dependency on Russia. So you are already looking at a very favorable outlier that makes the situation look better than it actually is. Most other countries have a much greater dependency.
