Check out this 1970s project that proposed extracting electricity from thermonuclear explosions.
https://en.wikipedia.org/wiki/Project_PACER
> A series of 50-kiloton bombs would be dropped into the cavern and exploded to heat the water and create steam. The steam would then power a secondary cooling loop for power extraction using a steam turbine. Dropping about two bombs a day would cause the system to reach thermal equilibrium, allowing the continual extraction of about 2 GW of electrical power
There was also project Plowshare, as chronicled by Kurzgesagt at https://www.youtube.com/watch?v=h3DCdWyb0cc
Which was building canals etc with nuclear bombs. https://en.wikipedia.org/wiki/Project_Plowshare
In the end we're just boiling water.
"Hey boss, do you think there is a chance this scheme might introduce radioactive byproducts into the ground water?"

Coming soon: thermonuclear fracking.
Already done https://en.wikipedia.org/wiki/Project_Gasbuggy
There goes another grant proposal into the bin...
