Lawrence Livermore National Laboratory is routinely tasked with tackling engineering and manufacturing challenges that have no existing solutions—often requiring the creation of entirely new materials, components, or systems that must perform reliably in extreme and hostile environments. These solutions must withstand unusual mechanical, thermal, or radiation stresses; maintain precise tolerance over many decades; and integrate complex functionalities. At the same time, Livermore’s solutions must be precise, effective, and timely to meet the needs of a dynamic national security environment. Traditional design cycles and manufacturing approaches—which rely on sequential prototyping and testing—cannot keep up with the urgent and highly specialized needs Livermore addresses through its mission.
The feature article in this issue of Science & Technology Review (S&TR) demonstrates how Livermore is leveraging its expertise and leadership in design optimization to meet evolving national security demands. Design optimization acts as a crucial bridge between additive manufacturing (AM) and high-performance computing (HPC), transforming the pace, efficiency, and effectiveness of engineering and design cycles. The Laboratory uses powerful computing codes such as LiDO (Livermore Design Optimization) and Smith, both developed at Lawrence Livermore, to automate and accelerate the exploration of complex design spaces by integrating HPC, AI, and advanced simulation tools. Through this work, Livermore can quickly evaluate thousands of potential design configurations, simulate and assess their performance under realistic conditions, and identify optimal solutions that best meet stringent and unique requirements—all in a fraction of the time that it would take with traditional design and manufacturing methods. By integrating advantages from design optimization techniques with AM methods such as 3D printing, Livermore can move from concept to prototype swiftly and efficiently.
As a cornerstone of the Laboratory’s ability to deliver advanced, mission-critical technologies, design optimization is but one of many examples of how Livermore’s research supports national security. The first highlight in this issue emphasizes the ongoing research into low-temperature radiation detectors that advances fundamental science and enhances the nation’s ability to more effectively detect nuclear material. The Beryllium-7 Electron capture in Superconducting Tunnel junctions experiment, as well as work with magnetic microcalorimeters and silicon quantum calorimeters, are leveraging extremely low-temperature environments to increase resolution and better identify energy signals from radioisotope decay. Outcomes and advancements in this research stand to benefit efforts behind nuclear forensics and broader nuclear security work, important components of Livermore’s national security mission.
The second highlight discusses Livermore’s research into an increasingly critical area of national security—the necessity of addressing wildfire risks across the country. Over the past decade, wildfires have increased in size and frequency, threatening the natural environment, towns and cities, and national security facilities, including National Nuclear Security Administration infrastructure. Lawrence Livermore is developing tools to understand wildfires in real-time to better inform prevention and mitigation practices. Through collaboration with the U.S. National Guard’s FireGuard service and the National Atmospheric Release Advisory Center, and by deploying the Laboratory’s HPC resources to analyze fire data, Livermore is charting new paths to improve firefighting tactics at home and around the country.
The technological advances presented in this issue of S&TR demonstrate Livermore’s comprehensive approach to national security. These efforts are key factors in addressing today’s most pressing threats and are laying the groundwork for innovative solutions to tomorrow’s emerging risks, ensuring the Laboratory remains at the forefront of safeguarding the nation.
