January-February 2019 NPJ

Nuclear Plant Journal, January-February 2019 NuclearPlantJournal.com 33 United Kingdom (UK) published its SMR market analysis in December 2014, estimating that the international market for SMRs is approximately $550B for the period 2023–2042. xii Conclusions From its inception, skeptics have challenged the potential of the NuScale SMR questioning its economics, contending the NRC would not approve key features of its design approach, doubting customer interest, and insisting there would be insurmountable challenges in manufacturing and performance. As shown here, NuScale has systematically worked through each of those concerns: the NuScale control room configuration is being accepted by theNRC; the elimination of requirements for Class 1E power has been approved; and a methodology has been adopted that has the potential to eliminate large emergency planning zones for NuScale plants. Verification testing, supplier input, and “bottom-up” cost estimates with detailed design input continue to provide confidence in the economic potential and manufacturing viability of the design. Confidence has been further enhanced by verification testing at component and integral system levels. While we agree that additional confirmation will be required with the construction and operation of an actual plant, customers familiar with the status of the NuScale SMR continue to show robust interest in its commercial potential. Taken together, we believe there is sufficient basis for optimism that the NuScale SMR will provide both unsurpassed safety and resilience and an economic nuclear option for significantly reducing carbon emissions in the near term.
