The article fails to mention the elephant in the room: damage from high-speed neutrons. From https://www.scientificamerican.com/article/can-small-fusion-energy-start-ups-conquer-the-problems-that-killed-the-giants/ https://www.scientificamerican.com/article/can-small-fusion-... Deuterium-tritium fusion releases most of its energy as high-speed neutrons, which damage steel parts and gradually turn them radioactive. In contrast, much simpler Molten-salt-fueled reactors can burn current stock piles of spent fuel rods. Safely generating electricity while reducing nuclear waste.
