Representative parameters are shown in Table 1. « lessĮarly work on TNS/PEPR at ORNL consisted of systems trade studies to establish a baseline design. The medium-field TNS reactor concepts and the plasma engineering innovations discussed should be applicable to other designs of tokamak reactors. It is shown that the previously anticipated requirement of high pellet velocities can be substantially reduced the toroidal field (TF) ripple requirements may be more » relaxed to reduce the number of TF coils and improve machine access hybrid equilibrium field (EF) coils have been shown to require building only small interior coils and to reduce the power supply required by the exterior coils proper approaches of microwave plasma preheating may reduce the peak loop voltage for start-up by an order of magnitude. Plasma engineering innovations that can substantially reduce the size, cost, and complexity of the TNS reactor have been explored and are summarized. values up to 10 percent and averaged densities between 0.6 x 10/sup 14/ cm/sup -3/ and 2.5 x 10/sup 14/ cm/sup -3/. Recent plasma engineering studies have ascertained a viable concept for The Next Step (TNS) reactor based on medium toroidal fields between 4 T and 7 T at the plasma center, plasma. The medium-field TNS reactor concepts and the plasma engineering innovations discussed should be applicable to other designs of tokamak reactors some of the suggested innovations will be tested In upcoming experiments. It is shown that the previously anticipated requirement of high pellet velocities can be substantially reduced the toroidal field (TF) ripple more » requirements may be relaxed to reduce the number of TF coils and improve machine access hybrid equilibrium field (EF) coils have been shown to require building only small interior coils and to reduce the power supply required by the exterior coils proper approaches of microwave plasma preheating nay reduce the peak loop voltage for start-up by an order of magnitude. Plasma engineering innovations that can substantially reduce the size, cost, and complexity of the TNS reactor have been explored and are summarized in this paper.
