Nuclear NewsNEW The Race to Power AI Is Reviving America's Nuclear AmbitionsRising electricity demand from artificial intelligence data centers is driving a surge in private investment for nuclear fission and fusion technologies. Venture capital funding for these sectors reached 4.5 billion dollars in 2026, as tech companies seek reliable, carbon-free power sources to support the rapid expansion of large-scale computing infrastructure. This influx of capital targets small modular reactors as a potential alternative to the high costs and long construction timelines associated with traditional large-scale plants like Plant Vogtle. While the industry faces challenges in proving the economic viability of new designs, the shift in energy demand is creating new opportunities for developers to test and deploy advanced nuclear technologies. AI-driven electricity demand is...

Core ContentNuclear NewsNEW Two new ANS standards issuedThe American National Standards Institute approved two new American Nuclear Society standards for reactor design and safety. ANSI/ANS-56.2-2026 updates requirements for containment isolation systems following a loss-of-coolant accident in light water reactors. Additionally, ANS-GS-30.1-2026 provides a technology-neutral framework for integrating risk-informed and performance-based methods into the design of new nuclear reactors. Two new American Nuclear Society standards recently received approval from the American National Standards Institute (ANSI). The new standard ANSI/ANS-56.2-2026, Containment Isolation Provisions for Fluid Systems After a LOCA, is a revision of historic ANS-56.2-1984 (W1999). ANS-GS-30.1-2026, Integrating Risk and Performance Objectives into… Both standards are available for purchase in the ANS Online Store. ANSI/ANS-56.2-2026: Containment Isolation Provisions for Fluid Systems After a LOCA specifies minimum design, actuation, testing, and maintenance requirements for the containment isolation of fluid systems that penetrate the primary containment of light wa...Core Content
