A method comprising: supplying deuterium to a fusion reactor ; conducting deuterium-deuterium (D-D) fusion reactions to produce reaction products comprising 3 He and tritium byproducts; pulsing the fusion reactor by sequentially energizing formation coils of the fusion reactor for simultaneously forming, accelerating and compressing filed reversed configuration plasmoids and for allowing access to reaction products which allows removal of tritium byproducts formed during the D-D fusion reactions; removing, responsive to the pulsing of the fusion reactor, at least some of the tritium byproducts from the fusion reactor produced in the D-D fusion reaction prior to a D-T fusion reaction; the method characterised by 1) creating 3 He through decay of the removed tritium byproducts, wherein a quantity of deuterium and rate fusion reactions are selected such that an amount of the 3 He to be produced through the decay of the tritium byproducts from said fusion reactor allows for a self-sustaining D- 3 He fuel cycle; and/or 2) creating 3 He through decay of tritium byproducts produced in another fusion reactor, wherein a quantity of deuterium and rate of the fusion reactions are selected such that an amount of the 3 He to be produced through the decay of the tritium byproducts from said another fusion reactor allows for a self-sustaining D- 3 He fuel cycle. supplying deuterium to a fusion reactor ; conducting deuterium-deuterium (D-D) fusion reactions to produce reaction products comprising 3 He and tritium byproducts; pulsing the fusion reactor by sequentially energizing formation coils of the fusion reactor for simultaneously forming, accelerating and compressing filed reversed configuration plasmoids and for allowing access to reaction products which allows removal of tritium byproducts formed during the D-D fusion reactions; removing, responsive to the pulsing of the fusion reactor, at least some of the tritium byproducts from the fusion reactor produced in the D-D fusion reaction prior to a D-T fusion reaction; the method characterised by 1) creating 3 He through decay of the removed tritium byproducts, wherein a quantity of deuterium and rate fusion reactions are selected such that an amount of the 3 He to be produced through the decay of the tritium byproducts from said fusion reactor allows for a self-sustaining D- 3 He fuel cycle; and/or 2) creating 3 He through decay of tritium byproducts produced in another fusion reactor, wherein a quantity of deuterium and rate of the fusion reactions are selected such that an amount of the 3 He to be produced through the decay of the tritium byproducts from said another fusion reactor allows for a self-sustaining D- 3 He fuel cycle. 1) creating 3 He through decay of the removed tritium byproducts, wherein a quantity of deuterium and rate fusion reactions are selected such that an amount of the 3 He to be produced through the decay of the tritium byproducts from said fusion reactor allows for a self-sustaining D- 3 He fuel cycle; and/or 2) creating 3 He through decay of tritium byproducts produced in another fusion reactor, wherein a quantity of deuterium and rate of the fusion reactions are selected such that an amount of the 3 He to be produced through the decay of the tritium byproducts from said another fusion reactor allows for a self-sustaining D- 3 He fuel cycle. <EOS>
