Engineering concepts for laser-fusion reactor applications

The long-range goal of the ERDA Laser Fusion Program is the production of commercial electric power. Although the scientific feasibility of significant thermonuclear energy release from laser-imploded and -heated pellets remains to be demonstrated, significant progress has been made, and many technological problems associated with ultimate applications of laser fusion are being investigated. Preliminary evaluations of several laser fusion reactor concepts have been made, and the most promising concepts, employing different methods for protecting structural components from damage by the products of fusion-pellet microexplosions, are being studied in detail. Engineering design and feasibility studies of other electric generating station subsystems are also under way. Continuing overall economic and technology tradeoff studies assess the economic pontential of various generating station concepts and provide guidance for research and development programs. (auth)
