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.

Neutral beams are injected into fusion devices through narrow transition ducts that are permeated by strong magnetic fields. As a result, the beam particles that undergo reionizing collisions with thermal gas molecules within the duct are deflected by the magnetic field onto the duct wall. This phenomena in conjunction with other related effects has been responsible for significant reduction in the amount of beam power reaching the plasma. This paper describes the development of a self-consistent beam transport model that was extensively used in the design of neutral beam injector system for the TDF central cell.
