2.3. REACTOR CONCEPT IMPROVEMENT 



The Fusion Working Group considered research on Tokamak improvements, open 

 systems (mirrors), and alternative and supporting systems (stel larator/ 

 heliotron, reverse field pinch (RFP), bumpy toroid programme (BTP), compact 

 toroids). 



1. It was noted that there is already a considerable degree of 

 international cooperation in these areas through both formal and informal 

 mechanisms. 



2. It was recommended that cooperation be also strengthened by implementing 

 the following formal agreements as soon as possible: 



- lEA Stellarator/Heliotron Agreement, 



- lEA RFP Agreement, which should be extended to include major new 

 devices such as RFX. 



Japan noted that it was not now in position to join in the Stellarator 

 agreement, but supported an early action by the US and EC. 



3. It was noted that three mechanisms have aided the optimization of world 

 resources in the past: 



- workshops to exchange information and plans; 



- personnel exchanges between countries; 



- selected input from foreign experts in technical reviews of national 

 programmes. 



It was recommended that these practices be continued and extended as 

 appropriate.
