Beyond the absence of greenhouse gas emissions or horrendously dangerous waste products, fusion also has a pronounced advantage over nuclear fission when it comes to safety. Radiological effects on people of any radioactive releases can be avoided. It is a Nuclear reaction- radioactivity will be there, BUT, in comparison to Fission, much much lesser. As the nuclei of two light atoms are brought closer to each other, they become increasingly destabilized, due to the electric repulsion of their positive charges. Safety Fusion power plants will be inherently safe. 1920 NUCLEAR FUSION, Vol.30, No.9 (1990) ECONOMY AND SAFETY OF FUSION REACTORS the blanket must also breed tritium since this element is not found naturally because it is radioactive and has a half-life of 12.3 years. Answer (1 of 11): It takes a staggering amount of heat and pressure to start and maintain a nuclear fusion reaction. It differs significantly from nuclear . But fusion reactors have other serious problems that also afflict today's fission reactors, including neutron radiation damage and radioactive waste, potential tritium release, the burden on coolant resources, outsize operating costs, and increased risks of nuclear weapons proliferation. China aims for nuclear fusion breakthrough. Fusion Reactions The concept of nuclear fusion has been described in Chapter 12. Fusion reactors mimic the nuclear process inside the sun, smashing lighter atoms together to turn them into heavier ones and releasing vast amounts of energy along the way. Inside our sun, two hydrogen atoms (the simplest element) fuse to create helium. It is summarized in Figure 14-1, which is analogous to Figure 13-2 for nuclear fission. Nuclear Fusion ~ Doesn't release harmful radiation ~ Waste is radioactive for 50 - 100 years ~ Reactors can't melt down and release radiation ~ Can be used in Nuclear bombs ~ Waste can't be used in bombs ~ Larger energy to fuel ratio Unlike nuclear fission, the nuclear fusion reaction in a tokamak is an inherently safe reaction.
