Advancing Nuclear Energy: NuScale's Small Modular Reactors
Written on
Introduction to Small Modular Reactors
NuScale Power, an American enterprise, is committed to delivering innovative nuclear technology through its Small Modular Reactors (SMRs). This approach offers carbon-neutral energy for generating electricity, heat, and potable water, all without the hefty financial burdens typically associated with larger nuclear power plants.
The U.S. Nuclear Regulatory Commission (NRC) recently instructed its staff to finalize a rule that certifies the design of NuScale’s small modular reactor for operation within the United States. This certification will take effect 30 days following its publication in the Federal Register, confirming that the design adheres to the necessary safety standards set by the NRC.
Energy 101: Small Modular Reactors
This video provides an overview of small modular reactors, explaining their design, benefits, and role in modern energy production.
NuScale’s inaugural commercial facility, featuring six modules of the VOYGR™ power plant, is slated for construction at the Idaho National Laboratory in collaboration with the Utah Associated Municipal Power Systems (UAMPS). According to NuScale’s official information, their SMRs can generate up to 300 megawatts of electricity. The modular design allows for factory construction, which is then transported to the installation site, eliminating extensive field construction, thereby reducing costs and construction time, while enhancing quality control.
Design and Safety Features
The NuScale Power Module™ (NPM) operates as a 77 Megawatt electric integral pressurized water reactor (PWR). It employs gravity-driven natural circulation for the primary coolant during both standard operations and shutdowns. Several NPMs can be combined to achieve a total output of 924 Mwe.
Spent fuel management includes storage in a concrete pool lined with stainless steel, where it remains submerged for at least five years. These pools are engineered to endure significant seismic activity and potential aircraft impacts, ensuring the integrity of the facility.
After the cooling period, the spent fuel is securely stored in certified dry casks on the plant's premises, adhering to the NRC's Waste Confidence Rule. NuScale also highlights existing technologies capable of reusing this spent fuel.
Innovative Safety Measures
NuScale’s SMRs incorporate a fully passive safety system design, enabling the reactors to autonomously shut down and cool without the need for human intervention, computer control, or additional water. This innovative approach significantly enhances the safety profile of the reactors.
NuScale maintains that nuclear energy remains essential for achieving climate objectives. Their SMRs are positioned to support renewable sources like wind and solar by providing consistent base load power and adapting to varying energy demands.
