Besides recent progresses in the physics-based modelling of fission gas and helium behaviour, thescarcity of experimental data concerning their combined behaviour (i.e., cocktail) hinders further modeldevelopments. For this reason, in this work, we propose a modelling methodology aimed at providingrecommendations for accelerated experimental investigations. By exploring a wide range of annealingtemperatures and cocktail compositions with a physics-based modelling approach we identify the mostinteresting conditions to be targeted by future experiments. To corroborate the recommendations arisingfrom the proposed methodology, we include a sensitivity analysis quantifying the impact of the modelparameters on fission gas and helium release, in conditions representative of high and low burnup
