The issue is that nuclear largely makes renewables redundant. Nuclear is just as cheap to run 24/7 as it is to run half the time, unlike fossil fuels. Right now, the way we're using intermittent sources is to shut fossil fuel plants off when renewables are producing and turn them back on when they are not producing. Intermittent sources are essentially supplementing a grid based in fossil fuels. If we use nuclear plants to fill in the gaps in intermittent sources' production curves, then we'd have already built enough nuclear capacity to run the grid without intermittent sources so we'd just run nuclear plants at full capacity and eliminate the need for intermittent sources.
