List of small nuclear reactor designs

Small modular reactors are approximately one-third the size of the current nuclear plants (about 350 MWe or less) and have compact and scalable designs which propose to offer a host of safety, construction and economic benefits by offering great potential for lower initial capital investment and scalability.

Status updated based on IAEA Report as of September 2014

NOTE Some reactors are not included in IAEA Report.
