Comparing the cost of a non-intermittent energy source with an intermittent energy source excluding the cost of storage is comparing apples to oranges. Solar and wind are cheap, until you saturate the energy market during peak production hours. Then it gets exorbitantly expensive. The only viable storage solution at the moment is hydroelectric, which is geographically limited. Global lithium ion battery output for a whole year doesn't even add up to 1 hour's worth of the USA's electricity consumption.
When probed on how to address intermittency, many wind and solar advocates propose things like hydrogen storage, giant flywheels, compressed air, or other solutions that are currently in the prototyping stage and have yet to actually be deployed to a grid and demonstrate viability.
This is the chief advantage of nuclear power: it works and we have over half a century of production experience with it. Betting on one of those storage solutions panning out is betting on a big unknown.
