This report is an introductory guide for potential investors in companies developing advanced nuclear technologies for electric power generation, industrial or district heating, hydrogen production, or other applications. The guide describes advanced reactor characteristics and considerations that may be of particular interest for evaluating investments. The focus of this guide is on fission technology, not fusion.

Deep decarbonization models generally have limited consideration of the unique characteristics of advanced reactors. This report identifies relevant future for energy system modelers to include advanced nuclear energy in future modeling efforts. For more information on how deep decarbonization models mischaracterize advanced nuclear energy and the challenges answered by this report, please refer to our blog post, Deep Decarbonization Models Miss the Mark on Advanced Nuclear Energy.

This primer provides basic information on advanced reactors to help the public and stakeholders understand the promise of innovative nuclear technologies. Dozens are under development around the world; this primer focuses on those in the United States and Canada.
