Nuclear is much cheaper when built at scale. Often 3-5x cheaper. Most of the plants built during the nuclear boom in the 1960s and 1970s were built at a cost of ~$2.5 billion per gigawatt of capacity. Note that this capacity is put out 24/7, so it's equivalent to about 4 times as much solar capacity (which typically has a capacity factor of ~25%). Solar and wind are cheap in terms of watts per day, but become drastically more expensive one you need to start adding storage. Storage costs are typically in the $200-400 per KWh range for battery storage, and $100 - $200 per KWh range for hydroelectric storage, but the latter is geographically limited.
