EURATOM FP6 EUROTRANS and FP7 CDT projects related to lead (-bismuth) cooled ADS. EFIT and FASTEF sub-critical cores design having different sizes and power levels. Detailed neutronic analyses in steady state by deterministic methods. Simple methodology to estimate the allowed operational sub-criticality level. Verification of the margins from criticality in accidental conditions.
