Future plans for energy production in the European Union as well as other locations call for a high penetration of renewable technologies (20% by 2020, and higher after 2020). The remaining energy requirements will be met by fossil fuels and nuclear energy. Smaller, less-capital intensive nuclear reactors are emerging as an alternative to fossil fuel and large nuclear systems. Approximately 50 small (<300 MWe) to medium-sized (<700 MWe) reactors (SMRs) concepts are being pursued for use in electricity and cogeneration (combined heat and power) markets. However, many of the SMRs are at the early design stage and full data needed for economic analysis or market assessment is not yet available. Therefore, the purpose of this study is to develop “target cost” estimates for reactors deployed in a range of competitive market situations (electricity prices ranging from 45–150 €/MWh). Parametric analysis was used to develop a cost breakdown for reactors that can compete against future natural gas and coal (with/without carbon capture) and large nuclear systems. Sensitivity analysis was performed to understand the impacts on competitiveness from key cost variables. This study suggests that SMRs may effectively compete in future electricity markets if their capital costs are controlled, favorable financing is obtained, and reactor capacity factors match those of current light water reactors. This methodology can be extended to cogeneration markets supporting a range of process heat applications.

As I see it, to prove that, it would be necessary to have sensors at all locations (or at least a large number of locations) where it would be reasonably possible to have wind and solar power installations. The data would have to be transmitted, in real-time, to a central location where it would be continuously analyzed to see how much power would be available reliably with no interruptions. So far as I know, that has never been done.

China’s Ministry of Railways spent $88 billion on HSR projects in 2009 – part of an existing $300 billion plan to expand and connect all of the country’s major cities with a projected 10,000 miles of dedicated HSR lines by 2020.
