Cortes FEEL - Fusion Energy Engineering Laboratory Escola Tècnica Superior d'Enginyeria Industrial de Barcelona Departament de Física i Enginyeria Nuclear, Universitat Politècnica de Catalunya Barcelona, Spain, http://www-sen.upc.es/Fusion Abstract SAFALY, a hybrid code comprising a zero dimensional plasma dynamics and a radial and poloidal thermal analysis of in-vessel components, is being progressively improved to discuss safety aspects of plasma-wall interactions in ITER. Overfueling by a factor 1.5, overfueling by a factor 3 and sudden suspension of fueling are chosen as scenarios to be simulated in current issue. Introduction SAFALY is a hybrid code comprising a zero dimensional plasma dynamics and a radial and poloidal thermal analysis of in-vessel components. It was initially adopted to assess abnormal events in fusion reactors from the safety point of view [1] and was progressively improved to analyse burn control, confinement mode transition or impurities transport among others in ITER EDA. Now, the Departament de Física i Enginyeria Nuclear of the Universitat Politècnica de Catalunya have made SAFALY suitable for ITER FEAT in order to simulate several accident scenarios challenging the integrity of the vacuum vessel and the other in-vessel components [2]. In the following, an outline of the code is presented and a brief remark of the updated models and parameters is shown. Fueling abnormalities, such as overfueling by a factor 1.5, overfueling by a factor 3 and sudden suspension of fueling are simulated for ITER 400MW steady state scenario in order to check the goodness of the modifications introduced in the former code. Further improvements and models are suggested as a summary after results analysis. 32nd EPS Conference on Plasma Phys. Tarragona, 27 June - 1 July 2005 ECA Vol.29C, P-2.106 (2005)
