PRELIMINARY INVESTIGATION INTO AEROSOL MOBILIZATION RESULTING FROM FUSION-REACTOR DISRUPTIONS

An experimental system has been developed to study disruption-induced aerosol mobilization for fusion accident analysis. The SIRENS high hea t flux facility at North Carolina State University has been modified t o closely simulate disruption conditions expected in tokamak reactors [1]. A hot vapor is formed by an ablation-controlled are and expansion cooled into a glass chamber, where particle condensation and growth o ccurs. The particles are collected and analyzed for relevant transport properties (e.g. size distribution and shape). Particle characterizat ion methods are discussed, and preliminary results based on simple ana lysis techniques are given.
