Project Overview

The U.S. Nuclear Regulatory Commission (NRC) is currently engaged in pre-application activities with X-Energy LLC starting in September 2018. X-Energy is a Rockville, MD company designing the Xe-100 reactor which is a pebble-bed, high-temperature gas-cooled reactor (HTGR). Each reactor will generate 200MWt and approximately 80MWe. The standard Xe-100 "four-pack" plant generates approximately 320MWe.

For more information, please see the Xe-100 reactor pre-application documents (NRC Docket 99902071).
