Saltfoss Energy

The reactor designed by Saltfoss Energy is called the Compact Molten Salt Reactor (CMSR). The company claims that it is inherently safe, significantly smaller, better for the environment, and inexpensive even compared to fossil fuel-based electricity. In early 2023 however, Saltfoss Energy made the decision to switch at least the first generation of developed reactors to Low-Enriched Uranium (LEU), instead of the originally planned High-Assay-Low-Enriched Uranium (HALEU) due to potential issues with HALEU supply, which did not meet their desired timeline for the CMSR. This involved switching the moderator to graphite from NaOH as well. In the case of an overheating accident, a frozen salt plug at the base of the reactor melts and the liquid fuel flows out of the reactor core away from the moderator into cooled tanks where the reaction quenches, the fuel cools and solidifies, without dispersing in the surrounding environment. The approach mitigates the danger of a failure rather than eliminating all failures. == Deployment ==

The company intends to deploy its shipping container sized reactors on barges. Reactors are manufactured at scale in a central facility, reducing costs. Using barges makes them mobile. Single reactor output is estimated to be 100 MWe. Multiple units could be deployed on a single barge. The primary design challenge is in preventing the highly corrosive fuel slurry and moderator from damaging the reactor. == References ==
