Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

The principle of the traveling wave direct energy converter is introduced. The mechanism is understood as a combination of the traveling wave tube and the linear accelerator. Hardware of the traveling wave direct energy converter is also introduced. It becomes obvious that the applied engineering and materials are conventional. The traveling wave direct energy converter is studied numerically. Self-excitation in a transmission circuit has been verified and optimized geometry is obtained with one-dimensional calculations. For a case of ARTEMIS, 69.8 % of overall conversion efficiency was obtained. Experiments on traveling wave direct converter have been carried out. Self-excitation of a traveling wave has been observed. As conclusions, a traveling wave direct energy converter appears promising to apply to an open magnetic system with D-3He fusion fuels.
