Amazing, a government agency standing in the way of technology. /sarcasm.

I know a lot about the "current" containment structures, and they are amazing pieces of engineering. I put quotes around "current," because the "current" containment buildings are based on what, 40 to 50 year old designs? So, it does not come as a huge surprise there is a better design out there. What, if any, fuel limitations does MHR have?

The Germans have made the most progress with development of coated particle fuel. Based on the German experience, this fuel can operate safely at 1300 C for extended periods during normal operation and can withstand a complete loss of cooling accident, where fuel temperatures reach 1600 C for short periods of time. This fuel design also allows for very high burnup in a single pass. Because of the fuel's high temperature capability, the MHR operates at a much higher thermal efficiency than water-cooled reactors (48% vs. 32%).
