Whacky! Why the hell would one use nuclear hydrogen to make electricity?
Why not use the nuclear energy to make elctricity directly in a Rankine
cycle steam plant as is now done? What is the hydrogen for? You imply using
hydrogen for some type of peaking cycle to boost the power plant's output
for peak requirements but it would be simpler and much cheaper to simply
scale the reactor for the peak reqirements. The additional generators and
other equipment are necessary anyway but no hydrogen storage or fuel boilers
would be required. Using nuclear thermal hydrogen as a syngas to synthesize
other fuels and chemicals may make some sense. That's the way most hydrogen
produced today is used.
