3 Work programme 2011: EURATOM Topic: Fission : Support for ESNII. Still within the context of assessing the potential of advanced nuclear systems, specific support for the European Sustainable Nuclear Industrial Initiative (ESNII), an industrial initiative within the Community's SET-Plan, will be made available in the following areas: (i) necessary R&D work on Codes and Standards for Generation-IV reactors, focusing on the prototype/demonstration reactors foreseen in ESNII; (ii) development and/or benchmarking of European computer codes for ESNII Fast Neutron Reactors, in particular relating to safety performance, leading to establishing a common platform for modelling and simulation; (iii) preliminary design work and/or coordination actions in relation to the principal ESNII infrastructure being promoted within ESFRI (European Strategy Forum for Research Infrastructures); (iv) support for new or refurbished supporting infrastructures needed by ESNII and identified within the ADRIANA project, for example more detailed design or licensing support. In all cases, work needs to be integrated within the ESNII Implementation Plan and be coordinated by the ESNII Task Force (or the eventual corresponding SET-Plan 'EII Team' and/or project level consortia); participation of the ESNII Task Force members and potential host organisations / countries essential.

6 SEARCH work programme Coolability of a wire spaced fuel assembly Can we keep the fuel cool at all times? Chemistry control Can we keep the coolant in the right condition? Fuel coolant interaction If the clad fails, is there an interaction issue? Fuel dispersion So the clad has failed : where does everything go? Release and capture studies for radioisotopes Can we keep the radioisotopes in and if not, where do they go? Education and training Next generation scientists and engineers
