Making them radioactive and destroy them. As a result, these materials must be periodically (a few years) to bury and replace with new. Protons, which are the result of nuclear fusion involving helium-3, on the contrary, do not penetrate deeply into the surrounding materials and does not induce radioactivity. Therefore, these materials and structures can serve for decades.In General, the above reaction is accompanied by radiation, but it (the reaction) is 50 times less radioactive than nuclear fusion, e.g. deuterium with tritium.Nuclear reaction of deuterium with tritium is described as follows:2H + 3H → 4He + n + 17,6 MeV,where 2H – deuterium, 3H – tritium, n is neutron.The disadvantage of the reaction of deuterium with tritium is that tritium itself is highly radioactive. Second, during this reaction there is a strong neutron radiation.The energy efficiency of helium-3 as fuel in the thermonuclear fusion is very huge. So, 1 ton of helium-3 replaces about 15-20 million tons of oil. Annual demand for helium-3 is around 20-30 tons, and of all mankind – 200 tons.The advantages of helium-3 as fuel:it is an ecologically pure thermonuclear fuel, by itself, helium-3 is non-radioactive and storage requires no special precautions– high energy efficiency,instead of the neutrons the reactor in the helium-3 emits protons, unlike neutrons are easily captured and can be used for additional power generation, for example, in the MHD generator,– the kinetic energy of the protons is directly converted into electricity through solid-state transformationreactor based on helium-3 has lower operating costs than traditional– in case of failure of reactor depressurization of the active zone, the radioactivity emissions are close to zero.Note: © Photo //www.pexels.com, //pixabay.com
