US small modular nuclear reactor has achieved design certification from regulator

The US Nuclear Regulatory Commission (NRC) has issued its so-called ‘Final Rule’ for the NuScale Power (NuScale) small modular nuclear reactor (SMR), completing the certification process for design. This made the NuScale SMR the first reactor in its category to be certified by the NRC. Although termed a ‘rule’, the NRC determination was actually a document some 55 A4 pages in length. This meant that, when the company applied for a licence to build and operate an NPP employing its SMR, the design of the SMR itself would not be an issue. NuScale would only need to meet the licensing requirements for the specific site chosen for the NPP.
