The success was attributed to newly developed high-temperature superconducting (HTS) magnets operating at 20 tesla. SPARC is now on track to deliver more than 100 megawatts of fusion power by 2028.\n- Source: https://cfs.energy/news/sparc-achieves-net-energy-gain\n\n## Analysis\n2. **ITER Progress: First Plasma Delayed to 2030, But Component Testing Advances**\n\nThe ITER project in France has delayed its first plasma target from 2025 to 2030 due to supply chain disruptions and technical integration challenges. However, in early 2026, all 18 toroidal field coils were delivered and tested, with cryogenic validation completed. The Central Solenoid Module 4, built by General Atomics, was shipped to Cadarache and successfully integrated.\n\nSource: https://www.iter.org/newsline/-/3675\n\n## Sources\n- https://cfs.energy/news/sparc-achieves-net-energy-gain\n- https://www.iter.org/newsline/-/3675\n- https://www.tokamakenergy.co.uk/news/st80-hts-fusion-milestone-2026\n- https://www.helionenergy.com/news/polaris-construction-update-april2026\n- https://www.nuscalepower.com/news/romania-approves-voygr-plant\n- https://www.cnnic.com.cn/en/2026/htr-pm-commercial-operation\n- https://www.x-energy.com/news/dow-xe-100-deployment-2026\n- https://www.terrapower.com/news/natrium-groundbreaking-april2026\n\n## Implications\n- The reactor, developed by China National Nuclear Corporation (CNNC), achieved a cap","keywords":["renewable-energy","climate-energy","zo-research"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
