Sandia National Laboratories (SNL) is partnering with Aeva Technologies, a California-based developer of next-generation sensing and perception systems, to jointly develop technologies that enhance the security of U.S. nuclear reactor sites.

Recently, SNL completed the initial evaluation phase of Aeva's 4D LiDAR technology. Currently, the laboratory is testing the technology at a reactor site to assess its capability to detect potential intrusion activities in perimeter areas (including intake structures), thereby strengthening security measures.

The 4D LiDAR system is a high-resolution sensor system that operates without GPS, built on Aeva's Atlas sensor. It can measure the velocity and direction at detection points and track the movement of objects in the surrounding environment. According to Aeva, this technology has broad applications in areas such as autonomous transportation navigation, industrial process monitoring, and more. Aeva also states that these sensors possess "all-weather operating capability" and can function normally in darkness, bright light, sunlight, fog, rain, dust, and other challenging conditions.

JR Russell, an engineer and researcher at Sandia National Laboratories specializing in the design and evaluation of intrusion detection systems, commented on the collaboration with Aeva: "Securing nuclear reactor infrastructure requires continuous innovation. Aeva's 4D LiDAR provides us with a new tool to detect potential threats in harsh environments where traditional sensors often struggle."

Following the completion of the initial evaluation phase of the 4D LiDAR, Aeva's Chief Engineer James Reuther stated: "We are moving into the next phase, testing our industry-leading LiDAR to help secure nuclear power plants. This is not only a significant milestone for the project but also marks the broader application of Aeva's 4D LiDAR in infrastructure security nationwide, including nuclear facilities, airports, power plants, and other critical sites."
