That sounds like an indictment of the commercial industry and deep corruption of US regulatory bodies. Its not an indictment of nuclear itself. The new designs are fundamentally safer, but i can see the value in the aegument that its not worth trying in as risky and corrupted a regulatory environment as the United States without significant political change first.
It's the exact opposite of your claim. In it he points out how the regulator actively worked to enable the nuclear industry in the US.
It's also worth nothing that this didn't appear to be corruption by any conventional definition. It seems more like the regulators believed that nuclear power was beneficial and acted based on that belief rather than a particular commercial motive.
