Survey of longer-term power plant concepts

The remaining concepts not yet discussed often employ significant innovation and, therefore, they may require multiple years of R D for technology development prior to a prototype integral demonstration. In general, if new fuel/cladding/coolant combinations are employed, the deployment times can be no sooner than 15-25 years. 

Given that nearer-term concepts already exist, the motivation for further innovations and R D expenditure is to enhance performance in one or more aspects, such as  

These enhanced features are intended to help nuclear energy secure a significant and growing role in long-term global energy supply.
