Bradley Gray Fusion doesn’t produce radioactive waste. 60 Years of Rod Stewart 1960 2020 signature shirt. Michael Miller The very high neutron flux of a deuterium-tritium fusion reactor is nothing to sneeze at. Plasma-facing components made of tungsten may be bumped to isotopes with a half-life of some months. Iron in the framework can produce iron-55, which is a problem for years. Cooling water headed toward steam turbines might make some tritium. All in all, vastly better than a once-through fuel cycle for a pressurized water fission reactor, but it shouldn’t be sold as “radioactive waste-free.” Bonni Bay They have no plan for the radioactive waste that already exists. The Japan tsunami and reactors are a fine example, maybe even the finest. Mark Ziering Temporarily?
No, neutrons emitted infusion can make things radioactive for very long periods; including the machinery and any cooling fluids. Rocky Giarratano Bradley Gray word. I read the top headline and feel like whoever wrote that didn’t even read the article. Very little to no radioactivity produced by fusion. 60 Years of Rod Stewart 1960 2020 signature shirt. Andreas Schmidt Mumm, It’s where extraterrestrial mining becomes interesting. Helium3 a heavy Helium isotope. Maybe with a fleet of self-replicating construction drones. Peter Card The fusion reaction in the sun’s core, short version, burning hydrogen to helium yields a pathetic power density, about the same as the resting human body. You would need the mass of small stars to sustain a useful power output. Gonçalo Castillo Meanwhile, harnessing nuclear power through fission continues to be the safest form of energy.
