Following the rst successful edition of FUNFI held in Varenna in yr 2011 ( Proceedings AIP Conference Nr 1442 , 2012, editors J Kallne, D Ryutov, G Gorini and C Sozzi) , we present the book of proceedings of the second edition of the conference. FUNFI2 is dedicated to the physics, technology and engineering of machines where fusion reactions drive a ssion blanket. Such hybrid devices can be used for energy generation, ssile fuel production and nuclear waste transmutation. The concept of Fusion-Fission hybrid (FFH) systems was introduced in a famous paper by H.Bethe (Physics Today 1979) and recently reviewed by H. Rebut (Plasma Physics Controlled Fusion 2006). The Deuterium-Tritium fusion reactions produce 14MeV neutrons which are able to induce ssion reactions in most of actinides including uranium 238 and thorium. The ssion reactions deliver an energy 10 times that of the neutrons produced by fusion: so with one ssion reaction per one fusion reaction there is an energy gain of 10. In this condition the fusion system producing neutrons can work at low minimum gain of Qfusion≈3 , for realizing a global energy gain of the integrated fusion- ssion system QFFH≈ 30. The main aim of FUNFI2 conference is to identify the proposals/projects with a high degree of reliability to make the technology available, making the analysis of the level of readiness of the technology for a medium term (25yrs) realization of a FFH reactor.

Il libro raccoglie gli atti della Seconda Conferenza Internazionale sui sistemi sub-critici per la fusione-fissione nucleare (FUNFI2), dedicati alla fisica, alla tecnologia ed all’ingegneria di dispositivi ibridi fusione-fissione nucleare. Tali dispositivi ibridi possono essere utilizzati per la generazione di energia, la produzione di combustibile fissile e la trasmutazione dei rifiuti nucleari. Il concetto di sistemi ibridi fusione-fissione nucleare è stato introdotto da H. Bethe (Physics Today 1979) e riproposto da H. Rebut (Plasma Physics Controlled Fusion 2006). L'obiettivo principale della Conferenza FUNFI2 è identificare le proposte/progetti con un elevato grado di affidabilità in maniera da rendere la tecnologia utile per la realizzazione a medio termine (25 anni) di un reattore ibrido fusione-fissione.

Abstract

Il libro raccoglie gli atti della Seconda Conferenza Internazionale sui sistemi sub-critici per la fusione-fissione nucleare (FUNFI2), dedicati alla fisica, alla tecnologia ed all’ingegneria di dispositivi ibridi fusione-fissione nucleare. Tali dispositivi ibridi possono essere utilizzati per la generazione di energia, la produzione di combustibile fissile e la trasmutazione dei rifiuti nucleari. Il concetto di sistemi ibridi fusione-fissione nucleare è stato introdotto da H. Bethe (Physics Today 1979) e riproposto da H. Rebut (Plasma Physics Controlled Fusion 2006). L'obiettivo principale della Conferenza FUNFI2 è identificare le proposte/progetti con un elevato grado di affidabilità in maniera da rendere la tecnologia utile per la realizzazione a medio termine (25 anni) di un reattore ibrido fusione-fissione.
