Abstract: Increasing global energy demand coupled with the need to reduce carbon and other greenhouse gases make investments in new carbon-free energy technologies more important than ever. One promising new technology is light water small modular nuclear reactors (SMRs). Their relatively small size, modular design, reduced construction times, enhanced safety and other features make them a potentially attractive energy source. A critical element in assessing their potential for future development, however, is their economic viability relative to other energy sources. The most common metric to assess a power system's economic viability is the levelized cost of electricity (LCOE). The LCOE method allows comparisons across energy producing technologies with different capital, operating, fuel, and other costs as well as different levels of power produced and operating horizons. The manufacture, construction and other initial capital costs loom large in LCOE calculations. To date, however, there has been substantial uncertainty regarding these capital costs for SMRs and, as a result, attendant uncertainty about the economic viability of SMRs relative to other energy sources.
