Produced by the Institute for Energy Economics and Financial Analysis (IEEFA), the report finds that SMRs are still too expensive, too slow to build, and too risky to play a significant role in transitioning away from fossil fuels.
According to the International Atomic Energy Agency over 80 SMR concepts are at some phase of development globally.
Advocates of SMRs believe the price and construction time of these power plants will be quicker and cheaper than previous nuclear projects. The new IEEFA report finds that the industry is still troubled by cost overruns and schedule delays.
“A key argument from SMR proponents is that the new reactors will be economically competitive,” David Schlissel, IEEFA director of resource planning analysis and co-author of the report said in a statement. “But the on-the-ground experience with the initial SMRs that have been built or that are currently under construction shows that this simply is not true.”

The report recommends that:
- Regulators who will be asked to approve utility or developer-backed SMR proposals should craft restrictions to prevent delays and cost increases from being pushed onto utility customers.
- Utilities that are considering SMRs should be required to compare the technology’s uncertain costs and completion dates with the known costs and construction timetables of renewable alternatives. Utilities that still opt for the SMR option should be required to put shareholder funds at risk if costs and construction times exceed utility estimates.
- State and federal governments should require that estimated SMR construction costs and schedules be publicly available so that utility customers, taxpayers and investors are better able to assess the magnitude of the SMR-related financial risks that they may be forced to bear.
- Finally, it is vital that this debate consider the opportunity costs associated with the push for SMRs. The money invested in SMRs will not be available for use in building out a wind, solar and battery storage resource base. These technologies are available today and can push the transition from fossil fuels forward significantly in the coming 10 years - years when SMRs will still be looking for licensing approval and construction funding.
“The comparison between building new SMRs and building renewable energy couldn’t be clearer,” said Dennis Wamsted, IEEFA energy analyst and co-author of the report. “Regulators, utilities, investors and government officials should acknowledge this and embrace the available reality: Renewables are the near-term solution.”
