NuScale Power Corporation (NYSE:SMR), the industry leading provider of proprietary and innovative advanced small modular reactor (SMR) technology, and MillenniTEK, an advanced nuclear materials manufacturer, today announced that they have successfully fabricated first-of-a-kind boron-oxide pellets for NuScale’s passive emergency core cooling system (ECCS).

The achievement marks an important step in NuScale’s continued progress toward commercialization readiness by furthering the development of specialized components and manufacturing processes that support the deployment of its U.S. Nuclear Regulatory Commission (NRC) approved SMR technology.

It also demonstrates NuScale’s commitment to safety, technical rigor, and the continued maturation of its supply chain and manufacturing capabilities. Upon ECCS actuation in a plant with NuScale technology, the pellets are designed to dissolve into the reactor coolant to help control and maintain core reactivity at safe levels without operator intervention.
