Price per kwh is not solely about generation efficiency, it's also about distribution and infrastructure. There will always be a cost associated with that which will rise with inflation. Even if we went totally renewable and all your electricity was "free" then you'd still have to account for on demand storage and infrastructure costs. The main benefit of nuclear is its relatively low carbon footprint and in theory less risk of spiking fuel costs because we run out of raw materials. That's the dream of fusion anyway. Nuclear power infra is not cheap and even fusion will have security and decommissioning costs. Forget cost as the main factor, grid power will never be free. That's a fantasy - even publicly owned utilities will/are funded by taxation. You're paying for price and power stability. Domestic fusion means you don't need to rely on foreign resources (eg Russia cutting off the gas). Putting renewable generators in your home has a high capital cost, but people forget that you're also cushioning yourself against grid outages. It's insurance more than anything else.
