Abstract

The ADS-demo is an intermediate step in the development of the Accelerator Driven System (ADS) aimed at the transmutation of Pu, MAs and LLFPs. This report concerns some aspects the ADS-demo fuel pin modelling in the so-called 'Enhanced Nominal Conditions'-case B (5). Some key points ara discussed by utilising TRANSURANUS code as the thermal feedback, FGR and corrosion behaviour of LBE-AISI316L system. Cladding swelling behaviour triggers thermal teedback and FGR (gas grain boundary concentration limit input is crucial for the ADS fuel pin modelling). The adopted corrosion hypothesis (30% cladding thickness corrosion at EOL) does not modify previous canclusions (5) on design limits veriticatian. The great flexibility and power of TRANSURANUS fuel rod analysis has been newly confirmed by developing the custom code and the statistic-deterministic mixed strategy herein adopted. The report refers to the P894 FIS-NUC project and more specifically to the activity items detailed in the work plan (1).
