NuScale Completes First Manufacturing of Boron Carbide Pellets for SMR Safety Component in the U.S.
NuScale Power and MillenniTEK recently announced that they have successfully manufactured the first batch of boron carbide pellets for NuScale's passive emergency core cooling system (ECCS). This component will be used in NuScale's small modular reactor (SMR) technology and is one of the dedicated components in its reactor safety system. According to reports, in nuclear power plants employing NuScale technology, when the emergency core cooling system is activated, the boron carbide pellets dissolve into the reactor coolant, helping to control and maintain core reactivity at safe levels without operator intervention. This manufacturing effort is considered a key advancement in NuScale's preparation for commercial deployment, involving the validation of dedicated safety components and associated manufacturing processes.
