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.

As one of thermofluid safety studies in ITER, buoyancy-driven exchange flow behavior through breaches of the vacuum vessel was investigated quantitatively using a preliminary LOVA (Loss Of VAcuum event) apparatus which simulated the Tokamak vacuum vessel of a fusion reactor with a small-scaled model. Helium gas and air were used as the working fluids. Experimental parameters were breach position, breach number, breach length, breach diameter, breach combination and the wall temperature of the VV. The present study showed that the relationship between the exchange rate and time depended on the magnitude of the potential energy from the ground level to the breach position and the wall temperature of the vacuum vessel. The exchange rate decreased as the breach length increased and the breach diameter decreased.
