WebbAn important example of nuclear fusion in nature is the production of energy in the Sun. In 1938, Hans Bethe proposed that the Sun produces energy when hydrogen nuclei ( 1 H) fuse into stable helium nuclei ( 4 He) in the Sun’s core ( Figure 10.22 ). This process, called the proton-proton chain, is summarized by three reactions: 1 1 H + 1 1 H ... Webb3.) The proton-proton chain is often described as "fusing four hydrogens into one helium," but actually six hydrogen nuclei are involved in the reaction. Why don't we include the other two nuclei in our description? Explain. 4.) On Earth, nuclear power plants use fission (nuclear reaction) to generate electricity. destiny2 light gg

WebbNuclear fusion mimics the natural reactions occurring within the Sun, and has been a goal of scientists around the world since the 1950s. The process has been hailed as the “holy grail” of clean energy, as it is almost limitless, requires no fossil fuels, and leaves behind no hazardous waste. WebbFusion reactions produce neutrons, with energy 2.45 MeV from the d-d reaction and 14 MeV from the d-t reaction, which have important applications as diagnostics. The neutron yields cover a wide dynamic range: from <1010 s −1 in small tokamaks, to ∼10 19 s −1 when JET and TFTR operate with tritium, yields will extend to ∼10 21 s −1 in ITER.
