The studies on the development of fusion–fission hybrid reactors (FFHR) have gained consensus in recent years as an intermediate step before fusion energy. This work proposes a possible approach to FFHRs based coupling Reversed Field Pinch machine and Molten Salt Subcritical fission test bed. proposed bed is characterized by coexistence fast-neutron core dedicated thermal-neutron zone, allowing performing tritium breeding actinides transmutation studies. neutronic design solutions results...
Fusion–fission hybrid reactors are concepts of subcritical based on the coupling fusion and fission devices. In this case, reactor would work as an external neutron supplier for core machine. Such systems could, in principle, operate multi-purpose machines, such energy generators, breeders waste burners. The large availability technologies makes choice devices to couple quite chaotic. fact, most proposed literature attempts without real optimization. purpose paper is propose a parameter...
New nuclear technologies are currently being study to face High Level Waste treatment and disposal issues. Generally, GEN-IV fission Fast Reactors (FR) considered the waste-burners of future. In fact, a fast flux turns out be best choice for actinides irradiation in critical reactors because favorable cross section conditions. Differently, Fusion Fission Hybrid (FFHR) futuristic devices based on combination fusion systems could represent an alternative FRs. such systems, spectrum neutron...
Abstract The strong toroidal magnetic field required for plasma confinement in tokamaks is generated by a set of D-shaped coils lying equidistant on meridian planes toroidally located around the central axis device. A major technological challenge tied to this configuration represented large Lorentz force acting and arising from interaction coils’ currents with coil system itself. As given cross product current field, various kinds geometry modification have been proposed alleviate problem,...
