The Biggest Nuclear Boondoggle Ever: Taxpayers, Pull out Your Wallet, Costs Exploded Again
by Wolf Richter, 15 October 2016
ITER uses the fusion of deuterium (D) and (radioactive) tritium (T). Each D-T-fusion produces an intermediate nucleus which emits a neutron having an energy of 14.1 MeV and is thereby receiving a recoil energy of 3.5 MeV (link).
These 17.6 MeV are╩
(1) mostly turned into radiation, which Lars and Nick referred to as electrical ╩energy, but part of the 17.6 MeV is
(2) dispersed in nuclear reactions mostly in the reactor structure, e.g. for breeding T from lithium, and render stable reactor structure radioactive.
The radiation energy (1) ends up as thermal energy and is eventually converted by turbines into electrical energy like in conventional power plants.
Because of processes (2) a fusion reactor power plant poses a radioactive hazard.╩
