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 . Ce concept de réacteur peut être rapproché de ceux du réacteur surgénérateur rapide, qui utilise un cœur de fission compact à haute énergie à la place du cœur de fusion de l'hybride et du réacteur nucléaire piloté par accélérateur, qui utilise un accélérateur de particules pour fournir les neutrons au lieu des réactions nucléaires.

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. In general terms, the hybrid is similar in concept to the fast breeder reactor, which uses a compact high-energy fission core in place of the hybrid's fusion core. Another similar concept is the accelerator-driven subcritical reactor, which uses a particle accelerator to provide the neutrons instead of nuclear reactions. (en)
  • 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 rifiuti radioattivi ad alta attività, le cosiddette scorie nucleari, l'uranio naturale o sviluppare il ciclo del torio-232. Ogni neutrone può poi innescare diversi eventi di fissione, moltiplicando per centinaia di volte l'energia rilasciata da ogni reazione di fusione, ma non si svilupperebbe una reazione a catena autosostenuta dalla fissione rendendo i progetti di fusione più economici in termini di potenza (it)
