Priority needs for advanced reactors

Items addressed by ANDES WP1 are marked

Besides these needs from the work of Subgroup 26 of the OECD-NEA there is work on needs that were established by IP-EUROTRANS and CANDIDE and by Subgroup 25 “Assessment of fission product decay data for decay heat calculations” This WP1 is inline with recommendations in the Strategic Research Agenda for improving basic nuclear data to improve modelling and simulation of advanced reactor systems

WP1 Deliverables

Impressive list of deliverables Addresses a large fraction of the advanced reactor systems high priorities Final impact can be judged on the basis of achieved measurement uncertainties and advanced reactor sensitivity studies
