The activities within the Association Euratom - Risø National Laboratory are divided into three parts: the 'Next Step', the 'Long Term' and the 'Underlying European Fusion Technology Programme'.
The investigations carried out in the field of the 'Next Step Technology' constitute a part of the European contribution to the 'International Fusion Technology Programme' aiming at design and construction of the International Thermonuclear Experimental Reactor (ITER). The activities in the Department in this area were concentrated on the effect of irradiation on copper and copper alloys, which possess the high thermal conductivity needed in components such as the first wall and divertors. Similar invesigations were carried out on titanium alloys.
The 'Long Term Technology Programme' covers activities dealing with the problems related to design and construction of the DEMO reactor (a demonstration fusion reactor). At Risø National Laboratory, irradiation effects on iron and low activation steels, which are considered as construction materials, were studied. Finally, the programme has activities within the Underlying European Fusion Technology Programme, where more fundamental aspects of irradiation effects are investigated.
The programme covers experimental investigation of effect of irradiation on changes in microstructural and mechanical properties using TEM, SEM , PAS and electrical resistivity measurements. Theoretical and simulation studies are also carried out (in collaboration with scientists from Europe, Russia, and USA). A workshop on 'Damage Production and Accumulation under Cascade Damage Conditions' was organised at the University of Liverpool, UK. |
