World Bank, IAEA partner to fund nuclear energy
The World Bank and the International Atomic Energy Agency signed an agreement last week to cooperate on the construction and financing of advanced nuclear projects in developing countries, marking the first partnership since the bank ended its ban on funding for nuclear energy projects.

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.
