EPJ A Review - Coherent Investigation of Nuclear Data at CEA DAM: Theoretical Models, Experiments, and Evaluated Data

Figure 1: (Bauge et al’s Fig. 46). Jezebel (a plutonium sphere) reactivity induced by components of the evaluated BRC09 and ENDF/B-VII.0 239Pu file, demonstrates that two different evaluated data sets predict the same k-eff criticality for different underlying reasons; one or more of them (probably both) are in need of improvements.

Dr. Eric Bauge et al describe a body of work accomplished by the CEA/DAM. Their goal is to determine accurate nuclear reaction cross sections for use in neutron transport codes. This work integrates theory and modeling, experiment, computer simulation, and statistical analysis. It involves researchers who thrive on multidisciplinary work, and who are motivated to achieve realistic simulation predictions in nuclear technology applications. Not only has the group succeeded in creating databases of accurate cross sections, but in every aspect of the work significant progress has been made in advancing our understanding of the underlying nuclear physics.

The article provides a unique analysis of advances in applied nuclear reaction physics, including, notably: (1) Fission and inelastic scattering using detailed nuclear structure descriptions of actinides; (2) Integral simulations of critical assemblies that reveal compensating errors between different reaction channels (Fig. 1) – this CEA discovery is now motivating the broader community to identify and eliminate deficiencies; (3) Identification of limitations on the applicability of the surrogate method for neutron capture.

CEA/DAM contributes to the Joint Evaluated Fusion and Fission File (JEFF3.1), the database that is used widely in European nuclear technologies. They collaborate closely with related efforts in the USA (ENDF/B-VII) and Japan (JENDL).

The authors show useful comparisons of their work against those based on ENDF/B-VII.0 and JENDL3.3-08, demonstrating the quality of these various capabilities. CEA/DAM strengths lie, in particular, in bringing microscopic theoretical insights in fission, coupled-channel optical model, and inelastic scattering to advance the quality of their application nuclear databases.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
