Nuclear Pulse - Weekly Intelligence Breaf
Week of 13-19 April 2026
India's Prototype Fast Breeder Reactor at Kalpakkam achieved first criticality on April 7, marking the country's definitive entry into Stage 2 of its three-stage nuclear programme and sending a powerful signal about breeder technology's viability for energy sovereignty [1]. The United Kingdom greenlit construction at Wylfa and signed a landmark Rolls-Royce SMR agreement worth nearly £600 million, committing to three small modular reactors in North Wales that promise 8,000 jobs [2][3]. The U.S. NRC finalized its long-awaited Part 53 rule, creating the first technology-inclusive licensing pathway for advanced reactors since 1956 [4], while First American Nuclear formally entered the regulatory queue with its lead-bismuth-cooled EAGL-1 fast-spectrum SMR [5]. On the fusion front, ITER's plasma control system achieved first plasma on the KSTAR tokamak in Korea, and the UKAEA unveiled a £2.5 billion 2026–2030 roadmap for commercial fusion [6][7].
