The Most Advanced SMR
Xe-100
The safest, most economic & most advanced design for a small modular nuclear reactor.
Proven Technology
The Peach Bottom unit 1 reactor in the United States was the first HTGR to produce electricity, and did so very successfully, with operation from 1966 through 1974 as a technology demonstrator. Fort St. Vrain Generating Station was commercial example of this design that operated as an HTGR from 1979 to 1989. The German THTR-300 was another commercial rector that operated between 1986 to 1989, and closed due to political decisions.
Experimental HTGRs have also existed in the United Kingdom (the Dragon reactor) and Germany (AVR), and currently exist in Japan (the High-temperature engineering test reactor using prismatic fuel with 30 MW of capacity) and China (the HTR-10, a pebble-bed design with 10 MW of generation). Two full-scale pebble-bed HTGRs, the HTR-PM reactors, each with 100 MW of electrical production capacity, have gone operational in China as of 2021.
Xe-100 Rector Design
Xe-100 is a 80 MWe reactor that can be scaled into a ‘four-pack’ 320 MWe power plant—with our modular design, the scale can grow even larger as needed.
TRISO-X Fuel
The most critical element in the design of advanced nuclear reactors is a robust fuel that can withstand very high temperatures without melting.
