Doosan Enerbility said Thursday that it has signed a contract to manufacture the Upper Reactor Pressure Vessel (URPV) for NuScale Power's Small Modular Reactor (SMR). This marks Doosan Enerbility's selection as the manufacturer of the reactor pressure vessel for the largest SMR project in the United States.
The signing ceremony between the two companies was held at Doosan Enerbility's headquarters in Changwon, Gyeongnam Province, on the same day. Attending the event were Carl Fisher, COO of NuScale Power, Kim Jong-doo, President of Doosan Enerbility's Nuclear Business Group (BG), and other executives from both firms.
Under this contract, Doosan Enerbility will manufacture the upper reactor pressure vessel for NuScale Power. The upper reactor pressure vessel is a critical piece of equipment that forms the top section of the reactor pressure vessel, which contains high-temperature and high-pressure coolant.
Previously, in 2023, Doosan Enerbility signed a contract with NuScale Power to manufacture SMR materials. With this new agreement, their cooperation has expanded from material preparation to the main manufacturing stage of commercial reactor equipment.
NuScale Power's SMR was the first in the United States to receive design approval from the Nuclear Regulatory Commission (NRC). An SMR is a type of reactor that manufactures major components in modular form and installs them on-site. Compared to large-scale nuclear power plants, it can reduce construction time and costs.
John Hopkins, CEO of NuScale Power, stated, "This contract represents a significant step forward in translating an NRC-approved design into actually supplyable modules." President Kim Jong-doo emphasized, "This contract is an important milestone in transitioning SMRs from the technical verification stage to the actual manufacturing stage."
