Response to the Proceedings of the National Academy of Sciences’ Paper on Spent Nuclear Fuel

Regarding the recently published paper in the Proceedings of the National Academy of Sciences, we are providing our response to the academy due to the factual errors related to NuScale’s technology and design contained within the paper. The paper uses:

  • Outdated design information for the energy capacity of the NuScale fuel design
  • Wrong assumptions for the material used in the reactor reflector
  • Incorrect assumptions on burnup of the fuel

With the correct inputs, NuScale’s design compares favorably with current large pressurized water reactors on spent fuel waste created per unit of energy. These inputs were available to the authors and their omission undermines the credibility of the paper and its conclusions.
