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.

An intense neutral beam injected into a plasma creates a tail (i.e. non-Maxwellian component) in velocity distribution function of the same species as the one injected with enhancing (or reducing) fusion reactivities from the values for Maxwellian plasmas. In a typical D-3He startup operation with field reversed configuration (FRC), tail effect on reduction in neutral beam injection (NBI) power required for plasma heating is investigated. It is shown that as a result of effective tail control, the required NBI power can be reduced by about 60 % from the value for Maxwellian plasma.
