Impact of SMRs

SMRs are a rapidly growing technology that has its positives and negatives.

SMRs energy output projection

Statistic

The stacked area graph depicts the projected global installed nuclear capacity (GWe) alongside cumulative CO₂ emissions avoided up to 2050. It compares conservative and ambitious projections of Small Modular Reactors (SMRs) deployment, along with large-scale nuclear builds and long-term operation of existing plants. The dashed horizontal line marks the IPCC's recommended nuclear capacity to meet 1.5°C scenarios. The shaded areas represent the contribution of each energy source type, showing an increasing role for SMRs, particularly in ambitious scenarios. This graph effectively highlights how ambitious SMR deployment can significantly reduce CO₂ emissions while contributing to the energy mix.

Slow development

Statistic

This horizontal bar graph shows the SMR development pipeline, categorizing reactor designs by their development stage. The first bar indicates concepts not actively developed, followed by designs making progress toward construction, and finally SMRs under construction or operating. The descending number of SMR designs from concept to deployment visually emphasizes the substantial drop-off, highlighting the challenges faced in progressing from theoretical designs to operational reactors.

Costs of Deploying SMRs

Statistic

The bar graph illustrates the rising construction cost estimates for SMRs from various developers (NuScale, X-Energy, and GE-Hitachi) over the years. Each bar set corresponds to different developers and specific years. The graph reveals a sharp increase in estimated costs per kilowatt ($/kW) from earlier projections to 2023, showing significant variability among developers. It clearly demonstrates the challenge of escalating costs, which could impact the financial feasibility of SMRs despite their modular advantages.
