 pebble bed nuclear reactors

The Pebble Bed Reactor is an advanced nuclear

reactor
design. This technology claims a dramatically higher level of safety and efficiency. Instead of water, it uses

helium as the coolant, at very high temperature, to drive a

directly. This eliminates the complex steam management system from the design, and increases the

transfer efficiency (ratio of electrical output to thermal output) to about 50%.



The technology in various forms is under development by MIT, the
