Zaporizhzhia ‘extremely fragile’ relying on single off-site power line, IAEA warns
Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

Thick-liquid pockets have the potential to protect structural materials and increase power density in heavy-ion fusion chambers. Here we show that cylindrical liquid jets have interesting advantages for creating shielding grids for heavy-ion beam lines. A cylindrical nozzle design with a very low convergence ratio was developed, and the fabrication methods needed for inexpensive numerically-controlled machining of large nozzle arrays demonstrated. Cylindrical jets were studied because they give the highest surface smoothness for a given degree of turbulence suppression, allow flow control to individual nozzles for control of jet pointing, and attenuate target-induced shocks effectively. Improved control of the grid geometry allows the driver energy to be delivered by a larger number of beams. These smaller beams–up to 160 in the example here–improve focusing and reduce neutron collimation up beam lines.
