Building a series of nuclear reactors with overlapping schedules (about one completion every year or two) in one country should help. But it’s simply far easier to find cost reductions for wind turbines which are manufactured in the thousands per year or solar panels and batteries which are manufactured in the millions.
Within a generation costs lowered, but between generations they exploded.
And the reductions were to small to make a dent in how horrifyingly expensive new built nuclear power is in 2026.
