This is happening now. Everyone is focused on getting to "net-zero" and switching to natural gas as a "transition" to cleaner, more sustainable energy sources. This has resulted in nuclear/coal going offline and being switched out for natural gas and natural gas prices shooting up like crazy, then war breaks out and natural gas imports are at risk and people still need power, so policy makers turn to "well maybe its time to switch the nuclear power plant back on?".
When things shift such that the short-term incentives shift away from the push towards the sustainable, renewable direction then it goes back the other way and it can and will happen.
