A realistic understanding of their costs and risks is critical.

What are SMRs?

  1. SMRs are not more economical than large reactors.

  2. SMRs are not generally safer or more secure than large light-water reactors.

  3. SMRs will not reduce the problem of what to do with radioactive waste.

  4. SMRs cannot be counted on to provide reliable and resilient off-the-grid power for facilities, such as data centers, bitcoin mining, hydrogen or petrochemical production.

  5. SMRs do not use fuel more efficiently than large reactors.

      At temperate latitudes, you can actually get something like 95% of the way there using wind, solar, and reasonable amounts of storage in addition to existing hydropower.

      This leaves a fairly small chunk which needs either long-duration storage or firm generation. Nuclear might be able to fill part of that, but only if it comes in at a lower price than currently seems likely. Other technologies, such as induced geothermal and sodium-ion flow batteries are a lot more likely-looking right now.

      No need for power generation dedicated to the base load.

      Nuclear power generation is base load only: it does not full the role of a peaker.

      Battery + renewable technology is already the primary source of power on many grids and the trend continues accelerating in that direction.
