FUSION ENERGY AND ITS ENVIRONMENTAL IMPACT
Nuclear fusion is pursued with considerable vigour in many countries because it has the potential of becoming an energy source with several attractive features. Most of them are related to favourable environmental impact and stem mainly from the very nature of the fusion reaction itself i.e. absence of radioactive fuel waste and minimum potential energy stored in the core of the reactor. A more detailed analysis of a fusion power reactor shows on the one hand other possible advantages (such as the shorter and/or lower activation of the reactor structures) and on the other hand areas of concern such as tritium inventory and volume of activated waste materials. To address these issues in the most realistic way NET (Next European Torus), a fusion apparatus now under design in Europe, is taken as a reference. NET in order to satisfy plasma physics requirements shall have a power output of several hundred megawatts and therefore it contains all the essential features of a reactor. A discussion of the physics and technological data base adopted in the design of NET provides also an updated assessment of the status and prospects of fusion research.
