Renewables don't need baseload help, they need dispatchability. So nukes would not help at all. Nukes will be mothballed in a few years as they become unable to attract bids sufficient to continue operation. (In some places they will continue getting their massive tax- or rate-payer subsidy.) As operation time falls, cost of every kWh they ever produced grows as the massive construction cost is amortized over fewer lifetime kWh. Fortunately, most storage technologies are nimbly dispatchable. They are not being built out much, yet, except for extra-short-term load shifting, and hydro cheaply retrofitted with a pump, because there is not enough renewable capacity to charge from. Until there is, combined-cycle NG turbines fill shortfalls. Build-out gradually reduces that expense, but not to zero. Instead, solar farms in the tropics fixing ammonia for export mean nobody needs more than a week of storage. The NG furnaces will be converted to burn ammonia, or maybe hydrogen extracted from ammonia. Catalytic fuel cells might enable retiring the gas turbines when they get cheap enough.
