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.

Experiments using a small-scale apparatus with 30 ml of actual high-level liquid waste from the Tokai Reprocessing Plant were carried out to show that the hydrogen concentration in the gas phase reaches a steady-state value of much less than 4% (lower explosive limit) in the absence of sweeping air. The H2 concentration reached a steady-state value as was expected, and it was compared with a value predicted from an equation with parameters that had been obtained using the simulated solution. Satisfactory agreement showed that the Pd-ion catalytic H2 consumption reaction previously found in the simulated solution proceeded equally well in the actual solution.
