SEOUL — Under an agreement with its U.S. partner, Nuscale Power, Doosan Enerbility, a key player in South Korea’s nuclear industry, will produce forging materials for small modular reactors as early as 2022, with expectations for large-scale equipment manufacturing by this last half of 2023.

The materials to be produced will support NuScale’s first commercial deployment of its power plant for Utah Associated Municipal Power Systems (UAMPS). Commercial operation of the first module is expected to begin in 2029. Doosan Enerbility will begin production of forging dies for NuScale’s upper reactor pressure vessel.

Doosan Enerbility is currently working on the development of a power module component prototype. The company would begin manufacturing large forged materials used for NuScale’s Small Modular Reactors (SMRs). “Doosan Enerbility has continuously cemented a strategic cooperative relationship with NuScale Power and made comprehensive preparation for SMR manufacturing,” Park Gee-won, CEO of Doosan Enerbility, said in a statement on April 25.

SMRs were designed to address the limitations of traditional light water reactors using low-enriched uranium which are expensive to replace nuclear fuel and require a large area for emergency evacuation, non-proliferation and disaster management. waste. Small reactors designed with modular technology allow for less on-site construction, increased containment efficiency and increased safety.

In 2019, Doosan Enerbility and South Korean investors invested $44 million in NuScale, followed by an additional $60 million investment in July 2021. NuScale’s SMRs are based on a safer, smaller, and development of pressurized water reactor technology. With NuScale’s scalable design, a power plant can accommodate up to 12 individual power modules. It houses the reactor core, the pressurizer and the steam generator inside a single containment building.

Nuscale, based in Portland, Oregon, aims to enter the global SMR market after successfully completing the UAMPS project. “Today’s announcement demonstrates NuScale’s commercial readiness and signals to the world that NuScale is truly the frontrunner in the race to bring SMRs to market,” said NuScale CEO John Hopkins.

Doosan Enerbility has accelerated the development of SMR manufacturing technology. In September 2021, the company entered into a contract with X-energy, a small US modular reactor company, to participate in the development of a high-temperature gas-cooled reactor that uses helium gas as a coolant instead some water.
