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 design of a double-null divertor for use in JT-60SU is presented. The free-boundary equilibrium code EFIT is used to establish a symmetric highly triangular double-null plasma shape. The baffle shapes are highly contoured to match the equilibrium, with the plasma-facing surfaces intersecting the flux surfaces at steep angles in the regions of high heat flux. These contoured surfaces also provide a tightly baffled design with small-aperture pumping gaps near both the inner and outer divertor strike points. The gaps provide adequate throughput of D2 gas for active control of impurity entrainment at reasonable pressures. The structural design is shown to be consistent with both forces from disruptions and thermal stress during vacuum vessel bakeout.
