Both companies are big, £87.97 billion ($118 billion) market cap in the case of Rolls-Royce Holdings PLC and $165.26 billion for GE Vernova. The both know a lot about stuff that spins and centrifugal and centripetal forces and all that. What more could you ask for.
A deep dive from Power Magazine who also know a bit about this stuff, August 21:
Swedish utility Vattenfall has narrowed its small modular reactor (SMR) supplier selection to two finalists—GE Vernova Hitachi Nuclear Energy’s (GVH’s) BWRX-300 and the Rolls-Royce SMR—for potential construction of new nuclear capacity adjacent to its Ringhals plant site on Sweden’s Värö Peninsula. The announcement represents a critical step in what could become Sweden’s first new nuclear build project in more than 40 years.
While the utility ultimately intends to select one SMR supplier from the two finalists, the selections unveiled on Aug. 21 stem from a rigorous process Vattenfall launched in 2024 to identify potential suppliers for Sweden’s first new nuclear project. Vattenfall said the project is necessary to meet rising electricity demand, bolster energy security, and advance the country’s net-zero targets.
The Swedish utility’s board formally decided on July 18, 2025, to build the new project following an extensive evaluation process that began with 75 potential suppliers and was narrowed to four candidates in fall 2024. The shortlist included GVH’s 300-MWe BWRX-300 SMR, Rolls-Royce’s 470-MWe pressurized water SMR, a large-scale design from Westinghouse, and a large-scale design from Électricité de France (EDF).
Vattenfall on Thursday said it is now planning a project with either five BWRX-300 SMRs or three Rolls-Royce SMRs, which could provide a total output of 1,500 MWe. “For comparison, a 500 MW SMR has the same capacity as the first large-scale reactor in Oskarshamn,” which began operation in 1972 with a design output of approximately 440–494 MWe.
“Among other things, an application for state risk sharing will be submitted and a final supplier selection will be made,” the company said. However, the utility is also looking at building another 1 GW in a “next step” on a site near Ringhals 1 and 2. “Final investment decisions will be made later in the process,” it said.....
