Popis: As part of the CAPRA Program (Consommation Accrue de Plutonium dans les RA pides) the feasibility of fast reactors is investigated to burn plutonium and also to destruct minor actinides. The design of CAPRA cores shows significant differences compared to conventional cores. Especially the high Pu-enrichment increases the recriticality risk and the associated energetics levels of secondary excursions. Other features of the core have the potential to mitigate this risk again. Of special importance are the numerous diluents in the core which might both prevent coherent liquid fuel compactive motions and can also be used as dedicated fuel discharge paths. The early release of fuel could prevent the escalation to large whole core pools with their energetics potentials.
