Description

Following the successful Coordinated Research Project (CRP) on Fuel Modelling in Accident Conditions (FUMAC) [1][2], the International Atomic Energy Agency (IAEA) initiated a new CRP ATF-TS in 2021 to support the development and evaluation of Advanced Technology and Accident Tolerant Fuels (ATFs) [2].

TRACTEBEL's contribution to the CRP ATF-TS focused on developing a methodology to assess the performance of Cr-coated cladding under Loss-of-Coolant Accident (LOCA) conditions. This involved improving the FRAPTRAN-1.5 fuel performance code and applying it to simulate experimental and reactor scenarios.
