Rationale
This action provides high quality neutron data standards and investigations of the fission process in fulfilment of the EURATOM Treaty. The action contributes to the European Research Area (ERA) by providing high accuracy nuclear data in support of the priorities of international organisations. The work performed in the action is mainly submitted and discusses with the IAEA (in participating to CRPs and Consultants meetings) and the NEA via the experimental nuclear data base. In this way the action supports the member States of the EC in their nuclear programs. The action will develop new measurement methods and theoretical capabilities for the analysis of the fission process in support of the Europe 2020 flagship Smart Growth. Within the agenda of Sustainable Growth, the action will also provide new evaluated nuclear data files and key experimental data for the nuclear reactions standards database, which is used in all validated nuclear data libraries, e.g. Joint Evaluated Fission and Fusion (JEFF) file and Evaluated Nuclear Data File (ENDF/B). Neutron data standards are basic data sets needed for experiments related to the assessment of reactor safety and nuclear waste minimisation. Since the majority of measurements in neutron physics are made relative to neutron data standards, the quality of experimental data is a key issue for improved safety of present day reactor systems. The data files used by industry and research laboratories have to be complete, accurate and validated by well defined quality assurance procedures.
This process of validation requires
• high-quality neutron data measurements using advanced facilities and equipment, based on well defined neutron sources and cross section standards
• state-of-the-art data analysis techniques, using improved codes
• whenever experiments are not feasible extensive theoretical work in order to complement the experimental nuclear data with calculated values
• close co-operation with other research institutes in order to optimise the use of resources
• participation in international data evaluation exercises and co-operation with industry for the definition of priorities of the work programme.

Based on the EURATOM Treaty the JRC has committed itself to ensure the establishment of a uniform nuclear terminology and a standard system of measurements and setting up a central bureau for nuclear measurements. The latter has been renamed JRC-IRMM.
Summary of the activity
This project is devoted to the study of neutron data standards and reaction theory and produces and improves neutron data for applications. The work programme follows the most urgent demands in close co-operation with international committees. Activities include support for the safety of current day reactors and spent fuel, nuclear waste management, and issues related to sustainability. To ensure customer orientation each project is embedded in collaborations with parties outside the JRC. JRC-IRMM represents the European Commission in the Nuclear Science Committee of the OECD Nuclear Energy Agency (NEA) and the Scientific Coordination Group of the Joint Evaluated Fission and Fusion file project (JEFF) of the NEA databank, as well as the OECD Working Party on Evaluation Co-operation (WPEC). JRC-IRMM is also involved in several IAEA Coordinated Research Projects (CRP) as well as in projects funded by the International Science and Technology Centre (ISTC). The key activities are

1. experimental and theoretical work for the understanding of the nuclear fission process

2. measurements of neutron data standards

3. development of improved measurement techniques using state-of-the-art digital signal processing technology

4. participate and contribute to internal and external international projects and network to support EC member states and associated states

These research activities are an excellent opportunity for training of young nuclear scientists in close collaboration with European Universities. Post doctoral fellows and visiting scientists from the major neutron data laboratories in the world, ensure a continuous information exchange on latest developments.
Via a cooperation of JRC-IRMM with JRC-IE (action 52303: CAPTURE) nuclear data not distributed via the NEA data bank will be made available to the international community.
The specialised facilities and its expertise enable JRC-IRMM to provide cross-section data over the complete neutron energy range from a few meV up to about 20 MeV. JRC-IRMM invests continuously in the upgrade of its accelerators and the laboratory equipment to keep them up-to-date. New developments in the use of digital data acquisition systems and signal processing are carried out as part of larger collaborations and will be used in measuring complex reactions needed for present day reactor and spent fuel safety and waste minimization.
There is a very close link to Action 51402 (ND-MINWASTE). For instance, in collaboration with the Action 51402 the neutron measurement facilities at JRC-IRMM are opened up to external users through the EUropean Facility for innovative ReActor and Transmutation neutron data (EUFRAT) project. Important benefits are drawn from action 53102 (METRO) that is responsible for the production and characterisation of the samples used for the measurements of the action. A close cooperation with JRC Action 51603 (RADMET) gives access to measurement capabilities in the radionuclide metrology laboratory of IRMM and the HADES underground laboratory for very-low-background measurements. Action is also participating in the European Research Infrastructure for Nuclear Data (ERINDA) and has several collaboration agreements with different partners in member states.
