Nuscale Power CorpNuScale successfully fabricated boron-oxide pellets for its passive emergency cooling system, advancing the SMR design toward commercial deployment

NuScale Power said it successfully fabricated specialized boron-oxide pellets, a critical component of its passive emergency cooling system, in collaboration with MilleniTEK on Sept. 1. The pellets, which automatically dissolve in reactor coolant to control core reactivity without operator intervention, are used in NuScale's 77 MWe Small Modular Reactor design and its Emergency Core Cooling System. The company said the fabrication milestone moves the pellets beyond a paper concept and one step closer to mass production and commercial deployment, and that producing the components before construction begins can shorten the supply process up front; NuScale has secured master service agreements with over 60 specialized suppliers. NuScale, the only small modular reactor developer to receive a Standard Design Approval from the Nuclear Regulatory Commission, currently has one project, the RoPower Doicești Project in Romania, where it plans to deploy up to six NuScale Power Modules with the first projected to come online in 2033. The company is also working with ENTRA1 Energy and hopes to close a deal with the Tennessee Valley Authority by year-end to explore deploying up to 6 GW, about 72, of its SMRs, though no firm commitment has been made.
