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.

The TFTR facility has recently undergone modifications that increase the auxiliary heating capability by the addition of 9 MW of ion cyclotron frequency heating power. In addition, one of the neutral injection beam lines has been reoriented to provide balanced injection capability at full power (27 MW). Results from experiments with this new capability are presented. The TFTR program calls for the initiation of D-T breakeven experiments in the 1990–1991 time frame; additional shielding, tritium neutral beams and reliability upgrades are all prerequisites for the D-T experiments. The planning for this D-T preparation program is discussed.
