As of now, no impact from earthquakes on nuclear safety & security in Türkiye, its Nuclear Regulatory Authority told IAEA; no issues so far related to radiological safety & security of radioactive sources, & the country's under construction nuclear power plant is unaffected.

[ITER @iterorg]

Effective fusion power production depends on keeping the plasmas clean from impurities. The head of #ITER's Science Division, Alberto Loarte, discusses recent scientific studies on this issue: https://t.co/nnl4wpViT2

[MPI für Plasmaphysik (IPP) @PlasmaphysikIPP]

Could atoms coming off the wall of the vacuum vessel contaminate the fusion plasmas in ITER? European researchers have now experimentally demonstrated that the plasma edge screens such atoms very effectively. #fusionenergy #nuclearfusion #physics #science https://t.co/PRKLwOL4e6
