常見錯誤

❌Nuclear fusion splits atoms apart to release energy.
✅Nuclear fusion joins atoms together to release energy.
💡Fusion means joining; splitting is fission.
❌A nuclear fusion reaction produces radioactive waste for thousands of years.
✅Nuclear fusion produces much less long-lived radioactive waste than nuclear fission.
💡Fusion's waste profile is dramatically cleaner than fission.
