Fusion energy
HSNet summary
This event compares how the ITER project and news organisations report on progress toward fusion energy. Every claim is attributed to its source. The first verified anchor is ITER's 2026 vacuum-vessel milestone; further milestones and independent assessments will be compared over time.
Sections carry a transparent verification status — verified sections cite the primary source; pending sections are disclosed rather than hidden. HSNet attributes every conclusion and does not issue a verdict.
This page compares official documents, investigative findings, government responses and media reporting. It is not legal advice and not a court judgment. HSNet does not determine legal truth; every conclusion is attributed to its source.

ITER's first 5,200-ton vacuum vessel built to contain plasma for fusion reactions
Reported the earlier completion of ITER's first vacuum-vessel sector and described the vessel as holding the fusion reactions; ITER's ~840 cubic metres of plasma is about ten times larger than existing tokamaks.
