Nuclear Pulse — Weekly Intelligence Brief **Issue 19** | Week of April 20–26, 2026

The defining development of this week is the commencement of construction on TerraPower’s Natrium sodium-cooled fast reactor in Kemmerer, Wyoming, marking the first utility-scale advanced nuclear build in the United States to break ground under a modern non-light-water design and signaling a genuine inflection point for the domestic advanced reactor industry [1]. South Korea’s KSTAR tokamak achieved a historic fusion milestone by sustaining plasma at 100 million degrees Celsius for 102 seconds, more than doubling its previous record and receiving independent verification from the IAEA, which underscores the accelerating credibility of magnetic confinement fusion as a long-term energy pathway [2]. Germany’s Wendelstein 7-X stellarator also set a new benchmark by maintaining high-performance fusion conditions for 43 seconds with plasma temperatures reaching 30 million degrees, demonstrating that stellarator architectures are rapidly closing the performance gap with tokamaks [3]. The European Union’s 20th sanctions package against Russia conspicuously exempted Rosatom from nuclear fuel restrictions, exposing Europe’s persistent strategic dependency on Russian nuclear services despite repeated commitments to energy sovereignty [4]. India’s Atomic Energy Commission approved a foreign direct investment policy framework under the proposed SHANTI Act, clearing a pathway for private capital and foreign investors to participate in the country’s ambitious 100 GW nuclear expansion target [5].
