Why do nuclear plants run with so little superheat??

This becomes less of an issue when dealing with HTGR (High Temperature Gas Reactors) however compact design is still key.

I think it is a great learning tool.
Thanks you

The above post was going to be a new post
Sorry about that

The maximum temperature in a coal fired boiler is 3500 to 4000 in the center of the flame
It then becomes how to best use this heat to generate the power, other limits in material strength at temperature then dictate what you can do.
Both steam cycles try to mimic the carnot cycle where they can to get the best efficiency

There was an externally fired superheat on one of the Con Ed reactors , which was an oil fired superheater.
The current research effort at the Gen IV supercritical reactor SCWR is attempting to show that superheat can be provided within the reactor, but my own opinion is that unbalances in flow to the "worst" channel would cause an unacceptable overheat in the outlet of that worst channel . Standard unbalances of channel effective diameter, heat flux patterns ( at worst unabalanced mdoerator condition), flow unbalance due to inlet distribution plate issues combined with the swift deteriioration in fluid heat capacity above the "pseudo critical point" has been shown ( in the 1950's) to lead to unacceptable outlet temperature unbalances when all heat is absorbed in a single pass device.
