Fusion - the programme in the UK - and other thoughts

The Fusion Programme in the Euratom--UKAEA Fusion Association is mainly one of plasma confinement studies in four major experimental areas. Conceptual studies of fusion reactors have been based upon the tokamak and the reversed field pinch. Particular attention has been given to the potential operating problems of toroidal fusion reactors in order to establish design principles which take note of the high availability essential in a power plant. Future plans for fusion power programmes are discussed and it is suggested that they are not obviously the quickest or most cost effective ways to establishing the credibility of fusion. It is proposed that a more aggressive programme which involved taking calculated risks could be quicker and cheaper. An additional, important advantage would be to attract into the fusion programme good engineers who feel the need to be motivated by action on a time scale less than the 30 to 50 years of much present planning
