1.1: fission cross section The target accuracy requirements for the integral parameters characterizing new fast reactor systems imply to reduce by a factor of 2 to 4 the uncertainty on actinide fission cross section measurements. This goal can be reached by the development of new detector devices which allow the use of the very precise standard H(n,p) cross section for the determination of induced neutron flux. Further, innovative fission detectors like time projection chamber have also to be developed to obtain better and more accurate nuclear data on fission observables. For accurate fission cross section measurements on actinides, two new setups, GRPD - gas recoil proton detector and a MicroMegas-based time projection chamber, will be then developed by respectively the CNRS/CENBG and the CEA/DRF/IRFU. Subtask 1.1.2: fission yields and decay data studies Fission yield studies for modelling and more accurate data for evaluation are of importance and requested for spent fuel heat prediction. In this task, CEA/DRF/IRFU will couple the FALSTAFF spectrometer (developed in the XXXXXX project) with the XXXXX gamma spectrometer at ILL. This new setup will allow the production of new accurate nuclear data on 235U and thus the improvement of the fission process modelling. This measurement is also supported in the WP 2. The JYU will improve the quality of the neutron induced fission product collection at IGISOL by the design of a new gas cell with electric field guidance. This new device will allow better efficiency which is expected to be of the order of 100 compared to what exist today. This improvement will benefit greatly for the fission products studies. Finally, for fission product decay data, UPC will build a new version of the BELEN detector (based on the Xxxxxx sphere principle) optimized for maximum total efficiency and spectrometric response and will measure beta-delayed- neutron spectra and Pn for selected fission product. This measurement is also supported in the WP 2. Within the decay data evaluation community a lack of suitable half-life and nuclear decay data measurement facilities has been highlighted and in order to answer this shortfall, the LNE-LNHB intends to contribute in this field. The measurement work at LNE-LNHB is undertaken with highly calibrated detectors, at a metrological level of precision, for all types of radiation. A new measureme...
