Deuteron-induced reactions at low and medium energies: Consistent direct and statistical model analyses

C. Project description

C4. Impact, relevance, applications.

The impact of eventual nuclear model improvements presumed by this project proposal is firstly related to a better understanding and description of the deuteron interaction, close to that presently available for nucleons or tightly bound composite particles like the alpha-particle. Following the completion of this objective, the role of deuterons and their interactions with nuclei may increase and even become similar to that of, e.g., neutrons for science (see the project NFS). Nevertheless, the enhanced knowledge on the deuteron nuclear interactions is requested and will be used straight away within the actual nuclear design projects of the IFMIF and SPIRAL-2 large-scale facilities. The improved model calculations will be equally well used for proposal of the new measurements of deuteron-induced reaction cross sections at SPIRAL-2 in the frame of the NFS project, while there are also plans for related experimental work at the IFIN-HH Tandem Van de Graaff accelerator.

Moreover, the largest scientific, social and economic impact of the eventual achievements within this project on deuteron-induced reactions will be directly related to fusion technology, with reference to various reaction contributions that have to be consistently as well as accurately considered within the deuteron activation assessment. Actually, the engineering design of IFMIF has already led to setting up of a priority list of target nuclei for which high accuracy deuteron activation cross sections are requested for, e.g., the accelerating cavities and beam transport elements (Al, Fe, Cr, Cu, Nb) and metal and gaseous impurities of the Li loop (Be, C, O, N, Na, K, S, Ca, Fe, Cr, Ni) in the energy range from the threshold up to 40 MeV1-3. Therefore, the development of theoretical reaction models through this project should and will be followed by the implementation of the related achievements in the associated codes used for activation cross sections calculations, within the NFS nuclear-data consortium. Former direct application should concern the deuteron interaction with, e.g., the 93Nb, 54,56,58,natFe and 58,60,61,62,natNi target nuclei.

Last but not least, this project may do possible, through the involvement of an early-stage researcher, a transfer of knowledge from older to the new generation of Romanian scientists. The still on-going financial crisis led to moving away the young people (two people in-between December 2008-April 2009) from the team that is proposing this project. The availability of decent income over three years for both an experienced and an early-stage researchers may do possible a transfer from the former to the latter of expertise and networking within international collaborations (F4E, NFS, NDS/IAEA) which otherwise will be loosed at the former retirement time.
