Nuclear is over 4x safer than solar [1]. As far as "not having the time", we'd still be using natural gas to accommodate wind and solar's intermittency unless some breakthrough in storage technology happens. Batteries are mostly going to go to vehicles, not grid scale plants. Other storage solutions like thermal batteries, compressed air, or giant flywheels remain in the prototyping phase and aren't even proven to be viable at scale.
