The person who wrote that has a conflict of interest, because he developed a nuclear reactor:

"In 2011, Devanney shifted his attention to nuclear power. He formed a small team to develop a design that combined a high temperature, low pressure, liquid fuel reactor with his background in ship production. This became known as the ThorCon project. Devanney continues to serve as ThorCon's Chairman although the day to day operations of ThorCon have been turned over to younger, more capable hands."

Or he knows what he's talking about. Could be either but you've chosen the reason that supports your perspective. I appreciate that he may be conflicted.
