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.

Rates of continuous tritium recovery from a Flibe stream are calculated for a permeation window and a counter-current gas-bubble column. The area of the permeation window is estimated to be comparatively small unless very low tritium partial pressure is demanded for the system. It is probable that the tritium transfer rate is controlled not by permeation through the window material (Nb or ferrite steel) but diffusion in Flibe. Since tritium diffusion in the molten salt is also determination of the recovery rate in the gas-bubble column from Flibe to He, the evaluation of the tritium diffusion resistance in the molten salt is crucial for its design.
