β¦ Synopsis
The first wall material problems and the structural mechanics studies being undertaken for the plasma facing components during the current pre-design phase of the Next European Torus (NET) project are described. The activities are aimed at generating the required materials data, setting up qualified analysis tools and criteria, and performing comparative design evaluations, thereby assisting in the final selection of materials and design concepts before embarking on the detailed design of NET at the end of the present decade.
Average neutron wall loading: 1 MW m-2; Average fluence (a) 0.8, (b) 2.8 MWy m-2; Burn pulse: 50 to 1000 s; Number of pulses: (a) 0.9 Γ 10 s, (b) 1.5 x 105; Surface heat flux: 0.15 MW m-2; Volumetric heat generation: 15 W cm-3; Coolant temperature: -250Β°C; Operation temperature range: -260 Β° to -500Β°C.
Because of the inadequacies of the existing data bases, many materials options are being retained during

## Abstract It is well known that, across all populations (based on geographic location, race, ethnicity, age, and sex), coronary artery disease (CAD) is the single most common cause of death. The commonly performed revascularization procedures for the treatment of symptomatic CAD are percutaneous
