Development of the darwin3-sfr fuel cycle toolfor decay heat calculations in new generation fast reactors

Abstract : The DARWIN3-SFR tool is the new calculation tool dedicated to the estimation of fuel cycle parameters (material balance, activity, radiotoxicity, etc), decay heat and material activation for GEN-IV reactors. The tool will be industrialized by the end of 2017; it will be used to perform cycle/decay heat calculations needed by the ASTRID preliminary safety report, foreseen at the end of the ASTRID Basic Design Phase in 2019. It integrates two calculation routes the APOLLO3®-MENDEL route and the TRIPOLI4-MENDEL route. The APOLLO3®-MENDEL route is operational. It integrates today the same functionalities as the previous tool used for SFR calculation, DARWIN2.3. It is more easily implemented, more flexible in use, than the previous DARWIN2-SFR tool, based on the ERANOS2 and DARWIN/PEPIN2 codes. The TRIPOLI4-MENDEL route will operational by 2017.The VetV-UQ process will be followed in the next DARWIN3-SFR version (V1). The numerical validation (it only concerns the neutron flux calculation step) will mainly consist in comparison between APOLLO3® calculations and reference Monte Carlo calculations at step 0. The experimental validation will be performed for the DARWIN3-SFR calculations concerning actinide material balance, decay heat and secondary sodium activation. The final quantification of calculation biases and uncertainties for the ASTRID cycle parameters will rely on both the experimental validation and a priori nuclear data uncertainty propagation (by deterministic approach).The DARWIN3-SFR first implementation was performed on the numerical benchmark described in this paper, which corresponds to a homogeneous sodium reactor core. It was the first demonstration of the APOLLO3®-MENDEL chaining feasibility.
