Abstract

PANCHO has been the essential platform for the ongoing development of FINIX fuel behaviour module and its accompanying automatic validation system. FINIX has been published through the OECD/NEA Data Bank, and has been licensed by several institutions around the world. The studies on fuel behaviour in accident conditions have been framed within the international projects, where the accident simulation codes have been tested and validated. A coupling between SCANAIR and GENFLO codes has been developed in the project.
The chemical experiments on nuclear fuel materials aimed to investigate characteristics of initial dissolution of crystalline ThO2 by adding 229Th tracer into the aqueous phase, and were conducted for total 534 days. The experimental campaign on cladding creep demonstrated that the VTT equipment is capable of performing suitable transient tests which support modelling efforts.
Three DSc theses were finalized based on the ongoing cladding creep modelling work, the modelling of fuel behavior in design basis accidents and fuel pellet dissolution experiments. One Master’s thesis is to be finalized from the work performed in this project.
