About using nuclear to cover seasonal variation, its not ideal, but at worst you increase the cost by 50-100%.

Day/night cycles can make that even slightly worse, but even small amounts of storage can even that out.

This Korean study claims that a at 3% dicount rate, the price the LCOE of their APR1400 reactors go from 36Won/kWh (a bit under 3cents) at 90% average utilization to 52Won/kWh (a bit over 4 cents) at 60% average utilization.

In both cases, the costs are very reasonable.
