S. fusion program following this significant change. The following discussion is framed in the context of the next few years. It provides only general guidance for the rest of the decade, because increased understanding of phenomena such as turbulence, transport, and magnetic reconnection is likely to change in very significant ways the course of ITER experiments.

6. Fueling, heating, and current drive control. The injection of frozen pellets of deuterium-tritium is a proven method to fuel fusion plasmas. The use of various heating and current drive control systems is well established. In essence, significant progress has been made in the development of the scientific and technological foundations needed to implement a fusion machine of the scale and nature of ITER. It is clear that ongoing research can be expected to adequately address issues requiring continued attention, but no issues remain that would undermine the fusion community’s assertion that it is ready to undertake a burning plasma experiment.

These criteria are discussed in more detail in Chapter 3 and are summarized here. Following are the six criteria for defining scientific readiness: 1. Confinement projections. Reaching the burning plasma regime depends critically on the rate at which energy is lost from the plasma. It is possible to predict accurately the energy-loss rate in existing tokamak experiments through confinement scaling studies; the present level of uncertainty in these projections is acceptable. 19 20 BURNING PLASMA 2.
