Small Modular Reactors: Pricey Power Down Under?
Small Modular Reactors (SMRs) are sparking a lot of interest as a potential answer to our growing energy demands. The core idea is simple: to develop smaller, more manageable nuclear reactors that can be pre-fabricated in a factory and then assembled on-site. But are SMRs a cost-effective way to power Australia's future, or are they just another expensive gamble in the energy market? Get3Quotes investigates.
What Exactly Are Small Modular Reactors (SMRs)?
Essentially, an SMR is a scaled-down version of a traditional nuclear power plant. The crucial differences lie in their size and modular design. Unlike large, custom-built nuclear facilities, SMRs are designed to be manufactured in a controlled factory setting and then transported for on-site assembly. This modular approach offers several potential advantages for energy generation:
- Reduced Upfront Costs: Their smaller size can lead to lower initial investment, making them potentially more accessible.
- Quicker Construction: Modular construction can significantly speed up the building process, reducing project timelines.
- Enhanced Safety Features: Many SMR designs incorporate passive safety mechanisms that rely on natural forces to safely shut down the reactor in the event of an emergency.
- Flexible Deployment Options: SMRs can be deployed in a wider range of locations, including remote communities and industrial facilities, offering greater flexibility in energy distribution.
While the concept sounds promising, the practical deployment of SMRs is still in its infancy. Currently, there are very few commercially operating, land-based SMR power stations around the world.
The Promise and the Challenge: Lessons from UAMPS and NuScale
One of the most closely watched SMR projects globally is the Utah Associated Municipal Power Systems (UAMPS) initiative in the United States. UAMPS plans to construct an SMR plant using technology developed by NuScale Power. NuScale's reactor design was the first SMR to receive design approval from the U.S. Nuclear Regulatory Commission (NRC) for its 50 MW modules back in 2020. They are now seeking approval for an updated design with a 77 MW capacity.
UAMPS aims to deploy a VOYGR nuclear power plant at the Idaho National Laboratory, with an ambitious target of being operational by 2030. However, this project vividly illustrates the challenges associated with SMR development, particularly when it comes to managing costs.
SMR Cost Blowouts: A Cause for Concern?
According to experts such as David Schlissel, Director of Resource Planning Analysis at the Institute for Energy Economics & Financial Analysis (IEEFA), the projected cost of power from the UAMPS project has increased dramatically. Initially, the target power price was USD $55 per megawatt-hour (MWh). That figure had already risen to $58 per MWh last year.
Now, Schlissel estimates that power prices from the project could potentially reach $90-$100 per MWh. And that's after accounting for a substantial $1.4 billion subsidy from the U.S. Department of Energy (DoE) and an additional $30 per MWh subsidy from the Inflation Reduction Act (IRA). This raises serious questions about the long-term economic viability of SMRs.
Historical trends in nuclear power development suggest that these cost estimates could potentially climb even higher. Schlissel points to the example of two new reactors at Georgia Power's Vogtle project, where costs have increased by a staggering 140% since construction began in 2011. Furthermore, these reactors are more than six years behind schedule.
What's Driving Up the Costs of SMRs?
Several factors contribute to the high cost of SMRs:
- First-of-a-Kind Expenses: As a relatively new technology, SMRs are subject to high initial engineering, design, and licensing costs. These are the costs associated with pioneering a new technology.
- Regulatory Hurdles: The regulatory landscape for SMRs is still developing, which can lead to delays, increased expenses, and uncertainty for investors.
- Supply Chain Complexities: Establishing a reliable and efficient supply chain for SMR components can be complex and costly, especially in the early stages of deployment.
- Economies of Scale Challenges: While SMRs are smaller than traditional reactors, they may not achieve the same economies of scale, potentially leading to higher per-unit costs.
SMRs vs. Renewables: An Australian Cost Perspective
Another crucial factor to consider is the cost competitiveness of alternative energy sources, particularly in the Australian context. Organisations like Australia's CSIRO have consistently found that renewable energy sources, such as wind and solar power, are the cheapest new-build electricity generation options, even when taking into account the costs of energy storage and transmission infrastructure.

This raises a fundamental question: are SMRs a worthwhile investment for Australia when cheaper, cleaner renewable alternatives are readily available and becoming increasingly affordable? While SMRs offer the potential for reliable, baseload power, their high cost and the abundance of renewable energy sources make their economic viability uncertain in the Australian energy market.

The Persistent Nuclear Waste Problem
Beyond cost considerations, another significant challenge associated with SMRs is the issue of nuclear waste. While SMRs may produce less waste per unit of energy compared to traditional reactors, the problem of long-term nuclear waste storage remains a major concern. Finding safe, secure, and permanent disposal solutions for nuclear waste is a complex and politically sensitive issue that needs to be addressed effectively. Contact us for more information.
SMRs in Australia: A Distant Reality?
Given the current ban on nuclear power in Australia, it's highly unlikely that we'll see SMRs deployed here in the near future. Even if the ban were lifted, the high cost and commercial immaturity of the technology make local SMR projects unlikely in the short to medium term, according to assessments by the CSIRO.

The Future of SMRs: A Balanced View
While the challenges are significant, there's still reason for cautious optimism about the future of SMRs. Ongoing research and development efforts are focused on reducing costs, improving safety features, and addressing the nuclear waste issue more effectively. If these efforts prove successful, SMRs could potentially play a valuable role in a diversified future clean energy mix. Learn more about emerging energy technologies.
Conclusion: Are SMRs a Prudent Investment for Australia?
Small Modular Reactors offer an intriguing vision of a future powered by clean, reliable nuclear energy. However, the high costs and other challenges associated with SMRs raise serious questions about their economic viability, particularly in the Australian context. With cheaper renewable energy alternatives readily available, it's crucial to carefully weigh the costs and benefits of SMRs before making any significant investments.
