Hybrid nuclear fusion–fission (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The basic idea is to use high-energy fast neutrons from a fusion reactor to trigger fission in non-fissile fuels like U-238 or Th-232. Each neutron can trigger several fission events, multiplying the energy released by each fusion reaction hundreds of times, but there is no self-sustaining chain reaction from fission. This would not only make fusion designs more economical in power terms, but also be able to burn fuels that were not suitable for use in conventional fission plants, even their nuclear waste.

  • Un réacteur nucléaire hybride fusion fission est un concept de réacteur qui utilise une combinaison de processus de fusion et de fission nucléaires. Dans un tel réacteur, des neutrons rapides à haute énergie provenant d'un réacteur à fusion déclenchent la fission de combustibles de manière sous-critique. Les réactions de fission ne seraient donc pas en chaîne auto-entretenue. Cela rendrait non seulement les conceptions de fusion plus économiques en termes d'énergie, mais serait également capable de brûler des combustibles qui ne conviendraient pas pour une utilisation dans les usines de fission conventionnelles, même leurs déchets nucléaires .

  • Il reattore nucleare ibrido a fissione-fusione è un reattore nucleare progettato per produrre in modo controllato reazioni di fissione nucleare sostenute dai neutroni veloci generati dalla fusione nucleare. Un reattore ibrido è quindi un rettore subcritico costituito da un nucleo per la fusione (fusion core) intorno al quale si sviluppa un mantello (blanket) di materiale fertile destinato alla fissione e alla fusione. Il nucleo per la fusione, analogamente a un acceleratore di particelle, costituisce la sorgente indipendente di neutroni veloci del rettore, consentendo così agli atomi del mantello di fissionare pur non avendo raggiunto la massa critica di materiale fissile. Un reattore ibrido, così come una reattore a neutroni veloci, può quindi impiegare come combustibile nucleare i rifiut (it)
