While nuclear certainty can adopt to grid demand quite well, if you have a good reactor.
However it leads to bad utilization of your plant.
For that reason, many of the next generation nuclear companies are designing their system to produce hot solar salt, like a Concentrated Solar Power Plant would.
Moltex Energy for example, hopes to deploy a 1GW reactor that heats up solar salt (ie heat battery), and then us that to drive 3 CCGT (Combined Cycle Gas Turbines) that are mass produced for coal and gas plants to produce 3GW of electricity when prices are high. This is a major improvement over traditional PWR have much less heat and have to use insanely expensive bespoke steam turbines (that are also insanely huge).
This is a good idea not just because it you can sell when prices are high and sell a lot, but also the nuclear island would only make a much smaller part of your total project cost, thus reducing the overall cost risk.

- nickik 7y agoIts by far my favorite design of all advanced reactors designs out there. Their solution for dealing with the 'pumping' problem is brilliant and their idea to make the liquid salt reducing is an incredibly neat way to avoid corrosion issues.
