Harder to find than a sponsor for a high-temperature toxic waste incinerator. Start a Post Learn more about posting on Energy Central . Large-scale nuclear projects with huge up-front costs have struggled to attract investment, putting the focus on smaller, cheaper reactors. But there will be a learning curve that goes along exactly what happened with large-scale computers. Remarkably, the new $89/MWh price of power would be much higher if it were not for more than $4 billion in subsidies NuScale and UAMPS expect to get from U.S. taxpayers through a $1.4 billion contribution from the Department of Energy and the estimated $30/MWh subsidy in the Inflation Reduction Act (IRA). The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other. While SMRs and microreactors are considered appropriate for niche markets today, this analysis shows that with significant volume, there is potential for their cost to decline enough to be competitive with large nuclear power plants. DOE Funding: Current Status and Future Prospects. As recently as mid-2021, the target price for power was pegged at $58 per megawatt-hour (MWh); its risen to $89/MWh, a 53% increase. National Academy of Engineering 500 Fifth Street, NW | Washington, DC 20001 T. 202.334.3200 | F. 202.334.2290, Fall Issue of The Bridge on Nuclear Energy Revisited. Folsom, California, Sr. Electrical Engineer That means a large 1-gigawatt reactor would cost around $5.4 billion to build, excluding financing costs. Bipartisan Carbon Border Adjustment Mechanism - A Political Unicorn? Despite these serious limitations, the scaling factors from the 1983 study are still widely used. The SPD encompasses 12,000 deliverables to support client-licensing and deployment activities including: Along with these deliverables, a comprehensive 3D model of the power plant was produced, providing an asset for potential customers to evaluate NuScales technology. The construction cost and target price estimates for the 462-megawatt (MW) small modular reactor (SMR) are going up, way up. Opinions expressed by Forbes Contributors are their own. THE BWRX-300 SMALL MODULAR REACTOR COST COMPETITIVE, CARBON-FREE ELECTRICITY GENERATION The BWRX-300 is a 300 MWe water-cooled, natural circulation Small Modular Reactor (SMR) with passive safety systems that leverages the design and licensing basis of GEH's U.S. NRC-certified ESBWR. From a geopolitical standpoint, the United States government should look at exporting this technology to developing countries for electricity production., If this nation is not involved, China and Russia will be, adds Jeff Merrifield, former Nuclear Regulatory Commissioner. Advanced nuclear reactors are estimated to cost $5,366 for every kilowatt of capacity. According to the U.S. Department of Energy (DOE) and some members of the nuclear industry, the next big thing in nuclear energy will be a small thing: the "small modular reactor" (SMR). With even modest learning rates of 1020 percent, SMRs could reach cost parity with large reactors after a dozen units, even if they start out at twice the cost. From the historical cost data, it is clear that most countries experienced economies of scale in their large reactor fleets, from a scaling factor of 0.2 in Canada to 0.8 in the United States. Today they exist only on the Rolls-Royce drawing boards they have adorned since the 1970s.. As recently as mid-2021, the target price for power was pegged at $58 per megawatt-hour (MWh); it's risen to $89/MWh, a 53% increase. The original target price in 2020 was $58MWH. Similarly, cost data are scarce for large-scale commercial power reactors recently built in China. Modesto Irrigation District LaVarr Webb, a UAMPS spokesperson, wrote in an email on January 24th to this blog that the information downloaded from a CFPP public facing web page is legitimate and correct., He added, as noted in the document, member participants have until February 17th to determine their status in the project. Bell Journal of Economics 13(2):297310. OCCi: overnight construction cost in 2010 USD per kW Architectural and construction drawings and specifications, Detailed system design specifications and calculations, Mechanical piping and instrumentation diagrams. To address these challenges, the nuclear industry is developing small modular reactors that generate less than 300 megawatts of electric power and can be assembled in factories. It will be fabricated in a factory and delivered to the site. To avoid system errors, if Chrome is your preferred browser, please update to the latest version of Chrome (81 or higher) or use an alternative browser. Cantor R, Hewlett J. The project still needs to go through additional design, licensing by the U.S. Nuclear Regulatory Commission, construction and pre-operational testing. Figure 1 shows the hypothetical FOAK costs for an SMR as a function of capacity (2.5300 MW, with four scaling curves covering the range of scaling factors considered by IAEA, n = 0.40.7. Electricite de France SA will build them by 2030. Washington, District of Columbia, Senior Customer Programs Transportation Electrification Manager Scaling the AP1000 cost down to the 60 MW NuScale reactor would result in a FOAK cost ranging from $9800/kW to $56,000/kW, depending on the scaling factor. A spokesperson for NuScale declined to comment on the CFPP budget and cost report referring all inquiries to UAMPS. Rolls-Royce has not yet released updated data on its cost estimate for the 16 reactors despite the fact that inflation in the UK is running at 9.2% annually according to the Office of National Statistics. Another found that increases in reactor size tended to extend construction duration and thus escalate costs (Cantor and Hewlett 1988). For small and microreactors, similar policies could include production and investment tax credits, federal power purchase agreements, state-level clean energy mandates, direct government procurement, and a streamlined licensing process for modular reactors. A cost competitive nuclear option for multiple applications. Assuming the commodity price increases cited by NuScale and UAMPS are accurate, the prices of building all the SMRs that NuScale is marketingand, indeed, of all of the SMR designs currently being marketed by any companywill be much higher than has been acknowledged, and the prices of the power produced by those SMRs will be much more expensive. To estimate the empirical scaling factors and learning rates in these groups, we construct a multiple linear regression with ordinary least squares. The open source format will allow startups, engineering firms, global utilities, and capital markets to align around a common framework. However, if economies of scale are less important (n = 0.8) and learning occurs faster (LR = 25 percent), then it would be necessary to deploy only 230 MW of the 60 MW reactor (4 units) or 32 MW of the 1.5 MW reactor (21 units). Energy Policy 91:37182. The discrepancy between modeled and projected FOAK costs highlights an important point: economies of scale and reactor capacity are not the only factors that will affect the cost of an SMR in comparison to a large NPP. NuScales power module is the only SMR design to date to receive approval from the NRC, which issued a Final Safety Evaluation Report for the 50 MW design in September 2020. This is a BETA experience. 2007. Nobody in the Hunter Valley has urged nuclear for the Liddell site, even on the footprint of this coal-fired power plant scheduled to close. However, the Inflation Reduction Act creates production tax credits for clean energy sources, including nuclear. Lovering J, King L, Nordhaus T. 2017. Academic M.V. Early studies of cost trends for nuclear power found that the technology had experienced positive learning (Cantor and Hewlett 1988): construction costs decreased with increased firm experience. resolution of remaining technical issues with support from owners engineers. Those right-sized reactors are emerging now that the U.S. government has incentivized them, making them more attractive for lenders and utilities. The economics of very small modular reactors in the North. The new 'saviours' for the nuclear industry are Small Modular Reactors (SMRs). The report estimates that the levelized cost of electricity for an SMR based on a pressurized water reactor design would be 86124/MWh with a central estimate of 101/MWh, and adds this caveat: "However it is recognised that SMR is a new technology and there is a substantial risk that these costs will be higher than this if costs accumulate Even the lower bound of nearly $10,000/kW is much higher than NuScales estimate of $4400/kW (NuScale 2020), which is actually less than the realized cost of the AP1000. Using the scaling equation above, it finds that the OCC of the FOAK SMR will be 74 percent higher, but the benefits from other factors reduce the total capital investment of the project to only 9 percent more than the large-scale plant. Energy Policy 86:198218. The decision takes effect on 02/21/23. Learning effects and the commercialization of new energy technologies: The case of nuclear power. The MCAs CEO Tania Constable said: Australia should take advantage of growing international interest in nuclear energy and look to expand its already significant uranium sector.. Recent large-scale reactor builds in the United States and Europe have been prohibitively expensive as costs escalated over time. Predictions for the growth of commercial nuclear power in the 1950s were predicated on the expectation that the larger reactors of the future would be more cost-efficient. As microreactors are deployed in series, unit costs are likely to decline in a process known as economies of volume or learning by doing. According to the new cost estimate, the producer price index for commodities such as carbon steel piping and fabricated steel plates has increased by over 50% since 2020. In 2019 Russia . The total cost per kW of electricity generated by a 114-MW small modular reactor unit is $2,653 compared to $4,764 per kW for a conventional pressurised water reactor unit of 1,144 MW, economic modelling data indicates. Even by the standards of the Minerals Council of Australia (MCA), the new reportpublished by the countrys most influential coal lobby on the subject of small modular nuclear reactors (SMRs) is jiggery-pokery of the highest order. For example, assuming a modest 2% inflation rate through 2030, utilities and ratepayers would pay $102 for each MWh of power from the SMRnot the $89 NuScale and UAMPS want them to believe they will pay. This study serves two purposes: first, it establishes realistic boundaries on the cost evolution of SMRs and microreactors to help inform investment policy; second, it provides empirical support for attempts to understand comparative learning and scaling effects in factory-fabricated nuclear reactors. How much do they cost, and how long will it take to build them? These so-called experience curves track industrywide learning across a country or region, rather than on an assembly line. Menlo Park, California, Senior Electrical Estimator Energy Procedia 7:5154. Benefits of Small Modular Reactors (SMRs) Small modular reactors offer a lower initial capital investment, greater scalability, and siting flexibility for locations unable to accommodate more traditional larger reactors. If small reactors can achieve consistent learning effects over sustained deployment, unit-cost parity with large designs may be possible. Rolls-Royce plans to have a reactor ready to send to the Moon by 2029. Approaches for Assessing the Economic Competitiveness of Small and Medium Sized Reactors. Small modular reactors will initially be far more expensive, mainly because the first iterations are now emerging, and the regulatory approval process is cumbersome. Enter small modular nuclear reactors, which may become the go-to energy source built to run consistently and as a flexible, carbon-free resource. Isnt It Time To Refill The Strategic Petroleum Reserve? where CostSMR is the overnight capital cost (OCC) of the SMR per unit of capacity, CostNPP is the OCC of a large-scale nuclear power plant (NPP) per unit of capacity, MWe is the rated power capacity of each, and n is the scaling factor. While the report is done, it has not yet been formally adopted by CFPP as part of its governance processes. [2] An obvious exception is, of course, nuclear navies. By combining analysis of scaling and learning effects, we explore theoretical deployment levels where SMRs and microreactors reach unit-cost parity with conventional reactors as a function of starting costs, learning rates, and scaling factors. development and implementation of an operating strategy, compliance with Department of Energy funding requirements, and. Using our multifactor regression and a dataset of 369 reactors in 8 countries, our model finds that most fleets experienced statistically significant negative learning (table 1). But more recent analyses have found negative learning, or forgetting by doing, where costs increase as firms or countries gain experience (Cooper 2010; Grubler 2010).[1]. UAE If you compare that to wind and solar, they generally have 20-year lifetimes and batteries of around eight years. WILMINGTON, North CarolinaMarch 15, 2023 GE Hitachi Nuclear Energy (GEH) today announced that its BWRX-300 small modular reactor (SMR) has achieved a significant pre-licensing milestone in Canada with the completion of phases one and two of the Canadian . Meantime, Ontario Power Generation is expected to start construction on a small modular reactor in late 2024 and will begin operating in 2028. TerraPower and GE Hitachi Nuclear Energy launched the so-called Natrium project in September 2020 a small modular reactor that they hope to commercialize by 2030. REUTERS/Phil Noble. Evaluating the role of unit size in learning-by-doing of energy technologies. Small Modular Reactors are a family of new nuclear technologies with the electrical output lower than 300 MWe. To calculate break-even deployment, each learning curve must be formulated as a function of deployed capacity, rather than units, so we replace u1 = G/s1 and u2 = G/s2, where G is the total capacity deployed for each reactor, and s1 and s2 are the sizes of each reactor. Many SMRs in developmenthigh-temperature gas-cooled reactors, salt-cooled, metal-cooled, and fastare non-LWRs. How is it possible to determine the trade-offs between large and small reactors before building the first SMR? How much does a single nuclear reactor cost? The MCA said in June 2020 that SMRs wont find a market unless they can produce power at a cost of A$60-$80 per megawatt hour (MWh). Mroz says it also applies to the industrial sector, pointing to chemical maker Dow, which will develop a small nuclear reactor. It is essentially the long-term price at which the electricity produced by a power plant will have to be sold at for the investor to cover all their costs. While the scaling relation assumes that the scaled-down technology remains broadly similar, it can be useful to apply such an equation to advanced SMRs and microreactors as a form of benchmarking. The applicability of the empirical scaling factors to a future small reactor design will depend on its similarity to existing technology. Washington, District of Columbia, Supervisor of Engineering - Substations DC Public Service Commission Elk River, Minnesota, Analyst/Director (DOE) That is the model for the small modular reactors.. 2020. These FOAK costs may be much higher than the eventual factory-fabricated units. The US, Russian, UK, and French navies have built small modular propulsion reactors for their nuclear submarines and aircraft carriers. The "Small Modular Reactor" (or SMR for short) would use the same kind of nuclear fission that we know can produce enormous amounts of clean energy in nuclear power stations - but on a far . According to aset of talking pointsprepared on January 3, 2023, by theCarbon Free Power Project(CFPP) there are new details about these costs. One study argued that the cost escalation experienced in the US nuclear power industry was caused by industry overestimation of the scaling effect, which led to an inefficient overincrease in unit size over time (Zimmerman 1982). Economies of Scale for Nuclear Power Plants. As an illustrative exercise, we apply the IAEA scaling relation (shown in the equation above) to the cost and size of a Westinghouse AP1000 reactor being built in the United States, assuming an OCC of $5500/kW and capacity of 1100 MW. In October 2020, the U.S. Department of Energy (DOE) approved a multi-year cost share award to a new special purpose entity named Carbon Free Power Project, LLC, an entity wholly owned by Utah Associated Municipal Power Systems (UAMPS), that could provide up to $1.4 billion to help demonstrate and deploy a NuScale power plant located at Idaho National Laboratory. 2013. While the precise cost of building one today is difficult to predict, a 2008 report by the consulting group Synapse Energy found that a new 1,110-megawatt plant could cost $6 billion to $9 billion. In an attempt to quantify the trade-offs between economies of scale and other economies for SMRs, the International Atomic Energy Agency (IAEA 2013) proposes a scaling relation to predict the first-of-a-kind (FOAK) cost for an SMR, given by the following equation: $$Cost_{SMR} = Cost_{NPP}\left({SMR \quad NWe \over NPP \quad MWe}\right)^{n-1}$$. SMRs can provide novel services that large designs have not, including off-grid and emergency power supply, and collocated industrial process heat. More renewable energy is necessary to meet the climate change challenge. No companies are cited in the report expressing interest in SMRs to power their mining operations. (Photo by Michael Williamson/The Washington Post via Getty Images). The costs of first-of-a-kind small modular nuclear power reactors (SMRs) and microreactors (<10 MWe capacity) are expected to be high when compared with those of historical large-scale light water reactors (LWRs). Construction costs per SMR reactor were claimed in 2016 to be less than that for a conventional nuclear plant, while exploitation costs may be higher for SMRs due to low scale economics and the higher number of reactors. The higher costs reflect the changing financial landscape for the development of energy projects nationwide. So here in the United States, there's a great opportunity, Mroz told the audience. The economics of nuclear power: Further evidence on learning, economies of scale, and regulatory effects. Policy challenges of nuclear reactor construction, cost escalation and crowding out alternatives. Energy Policy 34(17):321832. Bowers HI, Fuller LC, Meyers ML. The CFPP, which is to be built at the US Department of Energys Idaho National Laboratory at a site about 50 miles west of Idaho Falls, ID. Because of high commodity prices, and much higher interest rates, CFPP says the energy landscape today is much different than it was just two years ago. The project takes the engineering behind the most successful nuclear energy deployments to create the foundation for a new generation of power plants that are easier and more cost-effective to build. Many of the coal fire plants are facing tougher environmental regulations that will be taking effect in the next couple of years.
