FUMAC: IAEA’s Coordinated Research Project on Fuel Modelling in Accident Conditions

The Coordinated Research Project (CRP) T12028 on “FUel Modelling in Accident Conditions (FUMAC)” has the objective to better understand the fuel behaviour in accident situations through the identification of best practices in the application of relevant physical models and computer codes, used by different Member States, and the enhancement of their predictive capacities. For this purpose, collection of well checked results of accident simulation experiments and their analyses with advanced fuel performance codes, were carried out in the CRP. Three Research Coordination Meetings (RCMs) were held from 2014 to 2017, where results of the CRP participants were presented and thoroughly discussed. The main activities and results of the CRP are overviewed in the current paper.
