(Image: NuScale) The NuScale Power Module is a pressurised water reactor with all the components … Typically, the fuel will be low-enriched uranium contained in thousands of individual fuel pins. NuScale reactor Westinghouse AP1000 containment structure 44 … Defense-in-Depth • Multiple additional barriers to protect against the release of radiation to the environment. It has a 2-year refueling period. core, preventing heat removal for any size break. The NuScale reactor uses gravity and buoyancy to naturally circulate the cooling water. Downs said a NuScale Modular Reactor is a completely different take on a pressurized water reactor. Its small decay heat, inherent stability, and reactor physics eliminates fuel damage in all design basis events including those with failure of all control rods to insert. Many of the SMR designs in development simply shrink the systems of large-scale nuclear plants, using less fuel. The design is based on Multi-Application Small Light Water Reactor developed at Oregon State University in the early 2000s. Off-the-shelf components have been utilized to allow full reliance on existing operating experience to minimize fuel performance uncertainties. Our Small Modular Reactor (SMR) is premised on well-established nuclear technology principles with a focus on integration of components, simplification or elimination of systems, and use of passive safety features. The company developing small nuclear reactors that it plans to build near Idaho Falls has inked a deal with a crane company that will help support the project. As the first ever to receive U.S. Nuclear Regulatory Commission (NRC) design approval, the company's SMR features a fully factory fabricated NuScale Power Module™, capable of generating 77 megawatts of electricity (MWe). A single module can produce 60 MW of electricity, equivalent to 17,000 acres of wind, enough to power 50,000 homes. In the contact information of release dated Aug. 31, 2020, Brian Mershon's phone number should read: 864.281.6484 (instead of 864.282.6484). Fluor is a majority investor in NuScale Power, a small modular reactor (SMR) technology company based in Portland, Oregon. The reactor is much smaller than those at work in nuclear power plants today, and with its modular design, NuScale hopes to simplify things while also ensure that the reactor … The updat Once the boron dilution phenomenon is considered, the actuation of non-safety injection systems play an important role in the event progression following any accidents or AOOs which lead to the ECCS actuation. Furthermore, the scalable, 12-module power plant will now approach a size that makes it a true competitor for the gigawatt-size market. As a refresher, in the NuScale reactor, a core is kept cool by circulating normal fresh water, as happens in today’s operating nuclear plants on a much, much larger scale. NuScale’s reactor is 65 feet tall and 9 feet in diameter, and is housed in a containment vessel only slightly larger. Nuscale’s reactor will be just 76 feet (23 metres) high. Summary of NuScale Plant Resilience Features . And a NuScale reactor's core would contain only 8% as much fuel as the bigger reactor's core. NuScale is an integral pressurized-water reactor, designed by NuScale Power, LLC. NuScale’s system is also integral, meaning the fuel, steam, and generator will all be in one vessel. Robust HTP™ Technology The HTP™ spacer grid technology is an ideal platform for an SMR operating with natural circulation flow. NuScale Small Modular Reactor (SMR). Through this program, the Department has partnered with NuScale Power and Utah Associated Municipal Power Systems (UAMPS) to demonstrate a first-of-a-kind reactor technology at the Idaho National Laboratory this decade. The reactor vessel is enclosed in a containment vessel that sits in a pool of surrounding water. Small, efficient core design limits source term: The NuScale reactor has 1/20 of the nuclear fuel of a large scale reactor. The reactor’s small size also generates economic efficiencies. • Reactor core is 1/20th the size of large reactor cores • Integrated reactor design - no large-break loss-of-coolant accidents. Increasing the power generating capacity of a 12-module NuScale small modular reactor (SMR) plant by an additional 25% lowers the overnight capital cost of the facility on a per kilowatt basis from an expected $3600 to approximately $2850. Increasing the power generating capacity of a 12-module NuScale small modular reactor (SMR) plant by an additional 25 percent lowers the overnight capital cost of the facility on a per kilowatt basis from an expected $3,600 to approximately $2,850. NuScale also plans to increase the size of its reactor units from 50 MW to 60 MW units, which will require a separate design approval review, Lyman said. NuScale Power announced Monday that federal regulators have completed the second and third phases of the review of its small modular reactor (SMR) design, keeping it … More than 125 NuScale reactors could be put in a traditional reactor’s containment building, though the company plans to deploy them in groups of 12. The NuScale reactor coolant system (RCS) includes a reactor vessel with two integral once-through helical coil steam generators (SGs). According to the company, the NuScale SMR is more cost-effective in leveled cost of electricity (LCOE)—the lifetime cost of building and operating a plant divided by its lifetime output—compared to other low-carbon energy options. The design is small in size but excellent in its functioning. This groundbreaking small modular reactor (SMR) design features a fully factory-fabricated NuScale Power Module™ capable of generating 60 MW of electricity using a … Because NuScale’s modular reactor is relatively small—15 feet in diameter and 70 feet long—it can be deployed in places where large nuclear installations likely wouldn’t be used, such as in coastal cities in need of clean water sources. NuScale said its upgrade “lowers the overnight capital cost of the facility on a per kilowatt basis from an expected $3,600 to approximately $2,850. It has also announced options for smaller four-module and six-module plant sizes in addition to its flagship 12-module plant. The scalable, 12-module power plant will now approach a size that makes it a true competitor for the gigawatt-size market. Furthermore, the scalable, 12-module power plant will now approach a size that makes it a true competitor for the gigawatt-size market. A nuclear reactor core is the portion of a nuclear reactor containing the nuclear fuel components where the nuclear reactions take place and the heat is generated. This unparalleled safety is foundational to the new level of plant resilience we offer at NuScale. NuScale Final Safety Analysis Report Summary Description Tier 2 4.1-1 Revision 1 CHAPTER 4 REACTOR 4.1 Summary Description The NuScale Power Module (NPM) is a self-contained nuclear steam supply system comprised of a reactor core, a pressurizer, and two steam generators integrated within the reactor NuScale Power has announced a 25% increase in power output for its NuScale Power Module small modular reactor, which it says will lead to significant cost savings. NuScale’s flexible design is redefining nuclear. NuScale has demonstrated 12 of its new design reactors functioning in a pool just the way reactors do in nuclear power plants. Originally a Department of Energy and Oregon State University project, the NuScale module reactors have been taken over by NuScale Power, Inc. “Furthermore, the scalable, 12-module power plant will now approach a size that makes it a true competitor for the gigawatt-size market,” the company said. The NuScale is a light water reactor (LWR), with 235 U fuel enrichment of less than 5%. The NuScale small modular reactor (SMR) safely shuts down and self-cools, indefinitely, with no operator action, no AC or DC power, and no additional water – a first for commercial nuclear power. A plant with 12 modules would likely need to be located on a site of about 14 hectares, which is equivalent in size to about 14 rugby fields. Simplicity Enhances Safety. adequate and complete as NuScale reactor has ample water inventory to remove decay heat during the post ECCS operation. NuScale’s modular reactor is built with 76 feet tall (23 meters), 15 feet wide (4.5 meters) cylinder made of steel, and is capable of producing up to 50 megawatts of electricity.
