A brief summary is given of the plenary sessions of the 3rd IAEA Technical Committee Meeting and Workshop on Fusion Reactor Design and Technology. The large tokamak experiments now under construction have brought fusion research to the threshold of fusion reactor power. A number of major in-depth reactor design studies are reported such as the 650-MW INTOR near term experimental fusion reactor based upon essentially current technology. Also reported are studies of commercial reactor designs. Results are given of the discussions of seven workshops that were based on the papers presented. These groups evaluated the current status and identified key problem areas for each in the following areas: near-term tokamaks, long-term tokamaks, toroidal systems (alternative concepts), open systems, inertial confinement, systems (advanced fuels, hybrids, etc.), and fusion reactor materials. The importance of beginning now to prepare for the next major step in fusion reactor development was emphasized and the benefits of international co-operation were evident in the consensus reached in the INTOR results and the strong influence it has had on the direction of the leading national design efforts.
