The United Kingdom’s nuclear regulators—the Office for Nuclear Regulation (ONR), the Environment Agency, and Natural Resources Wales (NRW)—have announced the completion of step one of their generic design assessment (GDA) for Rolls-Royce SMR’s 470-MWe small modular reactor design and the start of step two, which is expected to last 16 months.

U.K.-based reactor developer Rolls-Royce SMR last week announced a list of six potential sites for its first small modular reactor factory. According to the company's announcement, the factory—the largest and most complex of three such facilities envisioned by the company—will manufacture the SMR vessels.

The U.K. government has released a new energy strategy aimed at boosting Britain’s energy independence, stabilizing its soaring energy prices, and accelerating the deployment of new nuclear, wind, solar, and hydrogen to mitigate climate change.

At the same time, the 38-page document, British Energy Security Strategy, calls for near-term support for domestic oil and gas, stating, “Net zero is a smooth transition, not an immediate extinction, for oil and gas.” (The United Kingdom in 2019 became the first of the world’s major economies to embrace a legal obligation to achieve net-zero carbon emissions by 2050.)

Following through with this strategy, the government says, could result in low-carbon sources generating up to 95 percent of British electricity by 2030.

The United Kingdom’s Department of Business, Energy and Industrial Strategy (BEIS) has asked regulators—including the U.K. Office for Nuclear Regulation (ONR), the Environment Agency, and Natural Resources Wales—to begin a generic design assessment (GDA) of Rolls-Royce SMR’s 470-MWe small modular reactor design.
