Nuclear 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 water reactors and include piping systems (including instrumentation and control) for all fluids entering or leaving the containment. This standard presents requirements and conditions that are needed for the isolation of the containment and… Read the full article at ans.org :

Nuclear NewsNEW DOE plans to expand WIPP’s capacity and operational lifeThe Department of Energy has amended its record of decision for the Waste Isolation Pilot Plant to extend operations by 50 years. The agency plans to excavate seven additional underground disposal panels to accommodate defense-related transuranic waste through 2083. This expansion supports the continued disposal of waste within the existing volume limits. The extension addresses the loss of original disposal panels due to ground instability and radiological contamination. By maintaining the facility, the DOE ensures a path for legacy waste currently stored at various generator sites. These ope...Core Content

Nuclear NewsNEW Adding carbon to tri-structural isotropic uranium fuelsResearchers used density functional theory to analyze how carbon additives alter the structural and elastic properties of uranium oxycarbide fuel kernels. The study indicates that carbon modifies directional stiffness and chemical bonding within the fuel, which influences how pellets respond to deformation. These findings will be integrated into multiscale fuel performance models to improve predictions of stress development and structural evolution during reactor operation. While added carbon can reduce the occurrence of carbon monoxide in uranium pellet fuels, the structural impacts have not...Core Content

Nuclear NewsNEW LLNL partners with industry to advance next-generation reactor fuelLawrence Livermore National Laboratory is partnering with startup AMPERA to develop thorium-based fuel kernels for TRISO fuel particles. The project, known as THUNDER, utilizes a metallic-particle manufacturing process called PowderJet to create uniform fuel precursors. This collaboration aims to improve the scalability and cost-efficiency of fuel production for advanced reactor designs. Advanced reactors require fuel capable of withstanding higher temperatures and longer operational cycles than traditional light water reactors. By leveraging thorium, which offers potential benefits in waste m...Core Content
