The Gas Dynamic Mirror seemed the most interesting and I got a lot of Google hits on it, but here are some guys working on actual proof of concept hardware.

The most powerful fission reactor engine ran for 12 minutes at 4,000 megawatts. The coolant/propulsion gas was hydrogen.
 

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...
