AbstractAbstractThe MUSE program (multiplication with an external source) is in progress at the MASURCA critical facility Cadarache Research Center of Commissariat à l’Energie Atomique France. The dedicated to physics studies accelerator-driven systems support transmutation minor actinides and long-lived fission products. It began 1995 coupling a Cf source was followed by commercial (d,T) source. In 2001, specially constructed (d,D)/(d,T) neutron generator (GENEPI) placed MUSE-4 commenced.We...

Interpretations of the MUSE-4, PROFIL, and PROFIL-2 experiments with latest version European library JEFF-3.1 have delivered reliable integral trends neutron-induced reactions on 242Pu. This paper reports improved modeling fission capture cross sections in unresolved resonance “continuum” energy ranges. The focus this study is description fast range average neutron properties deduced from statistical analysis resolved parameters nuclear systems n + 239Pu, 240Pu, 241Pu,

The JEFF-3.1.1 Nuclear Data Library is the latest version of Joint Evaluated Fission and Fusion Library. We present status validation this library using Monte Carlo Code TRIPOLI 4.5 deterministic code package ERANOS 2.2 for fast reactor calculations. For purpose, we reanalyze a selected set integral experiments performed in MASURCA mock-up (CEA/CADARACHE), ZPPR at ANL (USA), SUPERPHENIX Power Reactor. Furthermore, also analysis pure sample irradiation PROFIL PROFIL-2 PHENIX reactor, as kind...

Since 1991, the CEA has studied physics of hybrid systems, involving a sub-critical reactor coupled with an accelerator. These studies have provided information on potential systems to transmute actinides and, long lived fission products. The such system remains be proven, specifically in terms physical understanding different phenomena involved and their modelling, as well experimental validation environment/accelerator. This must achieved through mock-up environments source external...
