Nuclear data for radioactive waste management and safety of new reactor developments

Institute for Reference Materials and Measurements

Action: 51402

Acronym: ND Minwaste

Summary:

Summary of the project:

This project provides new experimental data for the assessment of reactor and spent fuel safety, nuclear waste management, the development of Accelerator Driven Systems (ADS) and Generation-IV systems. For the latter special attention will be given to the fast neutron energy range (1 keV-20 MeV). As a result of the cross-cutting nature of certain nuclear data measurements, results may be of relevance to other thematic areas of the general EURATOM programme such as nuclear fusion and security.

An integral part of this project involves active participation in the projects and committees of the Joint European Fission and Fusion file (JEFF) project, the Working Party for Evaluation Cooperation (WPEC), and the Nuclear Science Committee (NSC) of the OECD-NEA and Coordinated Research Projects (CRPs), Data Development Projects (DDPs) and the International Nuclear Data Committee of the IAEA-NDS.

Following a very successful NUDAME (Nuclear data measurements) transnational access project, use of the neutron measurement facilities by external users is supported through the follow-up transnational access project EUFRAT (European facility for innovative reactor and transmutation neutron data). EUFRAT started in 2008 and will run for four years. JRC-IRMM also participates in the EUROpean TRANSmutation (EUROTRANS) integrated project, the European Facilities for NUclear DAta measurements for Transmutation (EFNUDAT) integrated infrastructure initiative and has (projects in) collaboration agreements with Atomic Energy of Canada Limited (AECL), the Commissariat √† l'√Čnergie Atomique (CEA), the US Deparment of Energy (DOE), the Istituto Nazionale di Fisica Nucleare (INFN), the Institute for Nuclear Research and Nuclear Energy (INRNE) and the National Institute for Physics and Nuclear Energy (NIPNE).

The JRC-IRMM neutron physics laboratory operates two neutron sources dedicated to the study of neutron-induced reactions for nuclear energy applications. The GELINA facility is state-of-the-art in high resolution neutron time-of-flight measurements. Continuous technical developments and a strategic choice of research projects aim at maintaining scientific excellence concentrating on improvements of the existing equipment for measurements of total cross sections, neutron-induced inelastic scattering and neutron emission measurements, and neutron capture measurements. An exploratory research proposal aims at investigating the possibility of removing ambiguities in neutron resonance energy determination by SI-traceable methods. This is a prerequisite for accurate work at energies where the individual resonances can be resolved. Additional technical developments aim at consolidation of a new measurement setup for neutron elastic scattering, and the methodology of data analysis and interpretation will further be developed, especially in the energy range where the individual resonances overlap and cannot be resolved.

Research training activities include on-site guidance of PhD and post doctoral students and support to students from external organisations. Maintaining competence is effected through the engagement of temporary staff. Scientists from new Member States, Candidate and potential Candidate Countries are involved in the activities.

A strategy will be developed to make available to the international community nuclear data from JRC-IRMM which are not distributed via the OECD/NEA databank. This will be done using modern informatics tools in cooperation with JRC-IE (action 52303, CAPTURE).
