US Startup X-energy developing innovative Xe-100 “pebble bed” high temperature gas-cooled reactor

X-energy, a Greenbelt-based nuclear engineering company,recently
convened a group of world-renowned nuclear experts to discuss
best-practices in pebble fuel fabrication. X-energy will use the
spherical elements to fuel their Xe-100 gas-cooled nuclear reactor in
the mid-2020s. The Xe-100 is a “pebble bed” high temperature
gas-cooled reactor
(HTGR).

The Xe-100 is a helium-cooled “pebble bed” HTGR that operates at
125MWth and produces approximately 48MWe.

The Xe-100 will benefit from decades of research and safe operation in
pebble bed reactors internationally, and X-energy plans to bring the
remarkable features and benefits of pebble fuel to the United States
for the first time. The Xe-100 will be ultra-safe, small-scale,
compact, versatile, and able to respond in real-time to fluctuating
grid demands.http://nextbigfuture.com/2015/05/us-startup-x-energy-developing.html
