US Navy’s nuclear propulsion infrastructure to get upgrade with $85 million Amentum contract

US defense contractor Amentum has secured an $85 million contract to support the modernization of critical infrastructure within the US Navy’s Nuclear Propulsion Program (NNPP). The three-year agreement will focus on redesigning and upgrading spent fuel examination capabilities at the Naval Reactors Facility in Idaho, a key site responsible for supporting the Navy’s nuclear fleet. The new facility will allow scientists and engineers to analyze used fuel cores, comparing real-world performance data with predictions from advanced design and testing processes. The company points out that these efforts will help improve the safety, reliability, and long-term mission capability of the Navy’s nuclear-powered vessels. Strengthening the Navy’s nuclear fuel evaluation capabilities According to Mark Whitney, president of Amentum’s energy and environment business, the project reflects the company’s continued focus on providing the engineering expertise and operational support needed to sustain the US Navy’s nuclear-powered fleet. By upgrading critical spent fuel examination capabilities, Amentum aims to help the Navy better analyze, optimize, and extend the performance of nuclear fuel cores. The modernization effort is expected to provide engineers and scientists with improved tools and data to support future fleet readiness, safety, and reliability. Whitney further noted that Amentum’s broader nuclear expertise positions the company to support some of the most complex challenges in the sector. He said the company’s capabilities cover the full nuclear project lifecycle, delivering safe, innovative, and reliable solutions for customers worldwide. He also added that Amentum’s integrated global nuclear expertise enables the company to take on demanding projects, including efforts that support the US Navy in maintaining the effectiveness of its nuclear-powered fleet. Nuclear propulsion program marks decades of innovation and reliability For more than seven decades, the Navy’s NNPP has remained at the forefront of nuclear technology, developing advanced systems to power the Navy’s global fleet. The program has built a reputation for combining innovation, safety, reliability, and operational efficiency, enabling nuclear-powered vessels to perform critical missions around the world. Through continuous research, engineering advancements, and rigorous testing, the NNPP continues to support the long-term performance of the US Navy’s nuclear capabilities, Amentum highlights. A collaboration between the Department of Energy and the Department of the Navy, the NNPP is responsible for overseeing the design, development, and operational support required to sustain the Navy’s nuclear-powered fleet. The program plays a central role in maintaining US maritime advantage by ensuring warfighters have access to vessels with exceptional endurance, stealth, responsiveness, and advanced warfighting capabilities. Through its work across the nuclear propulsion lifecycle, the NNPP helps support the reliability of the Navy’s strategic naval assets. Furthermore, as operator of the world’s largest nuclear-powered fleet, including 11 active aircraft carriers and more than 70 submarines, the Navy relies on programs such as the NNPP and partners like Amentum to support the safety, performance, and long-term sustainability of its nuclear propulsion systems.
