Some Reactor Implications of Laser Fusion

  • Ian Spalding


Some technological aspects of blanket design, operating frequency, and pellet production in a laser-compression reactor are discussed. Economic implications of the concept are then reviewed: assuming electrical pumping of the laser system, it is important to minimize the circulating power by using very efficient lasers (ne ~ 0.15 – 0.30) and achieving a high burn up in the compressed core. The desirability of a high repetition rate (f ~ 50 Hz), to allow an adequate margin in the capital cost of laser components, is demonstrated, and an estimate of typical costs for a 530 MW(e) deuterium-tritium fuelled system is presented. Economic operation of a pure DD system is shown to be much more difficult to achieve. Finally, the way in which these conclusions may be modified by alternative laser pumping techniques, and some physical factors which might affect published thermonuclear gain calculations, are summarized.
