Nuclear offers emission-free, reliable energy to accelerate the shift away from fossil fuels and power a range of other uses including space exploration, desalination plants and data centers. Amentum is at the forefront of conceptual design and optimization of new nuclear technologies like Generation IV, small modular and advanced reactors and fusion power. Amentum is sharing its multi-technology expertise, deep nuclear knowledge, skills in advanced engineering and licensing, and special technical capabilities with small modular and advanced reactor developers from the UK, USA and continental Europe. We have a decades-long involvement in fusion power research with the UK Atomic Energy Authority and with ITER, the world’s largest nuclear fusion project, where our work ranges from designing prototypes for key components to complex remote handling systems essential for reactor operations. And we are creating the infrastructure for the hydrogen economy of the future, from feedstock processing facilities to converting the pipeline network.
