Problems for First Wall Materials in a Fusion Reactor
IN A FUTURE FUSION REACTOR THE FIRST WALL WILL PLAY AN IMPORTANT ROLE. IT WILL BE THE FIRST SOLID BARRIER FOR THE PLASMA AND IT WILL ACT AS A VACUUM BOUNDARY. DUE TO IT POSITION, IT WILL BE EXPOSED TO THE PLASMA AND SUFFER MULTIPLE DAMAGE AS NEUTRON RADIATION SPUTTERING ROSION, HYDROGEN CHARGING AND HIGH HEAT FLUX. THE LIFETIME OF THE FIRST WALL WILL THEREFORE BE LIMITED. THIS PAPER GIVES AN OVERVIEW OF THE DIFFERENT DAMAGE MECHANISMS AND THEIR INFLUENCE ON THE LIFITIME OF THE FIRST WALL.
