Things are more expensive when we keep reinventing the wheel and trying to do new things instead of just reusing proven designs. Remember that solar power also used to cost wheelbarrows of cash back in the day. When you do something repeatedly, it becomes less expensive over time.
Nuclear is actually the leader in waste management. No other energy source has as complete a story. Eg what happens to solar panels when they EOL in 25 years? They go into landfills and leach toxic chemicals into the ground. These chemicals, like lead and cadmium are toxic forever. They have no 'half-life' in which their toxicity reduces.
Solar panels are recycled at almost 100% of total materials. Redwood Materials (founded by Tesla's former CTO) has already established a supply chain to ingest and recycle EV and stationary storage batteries at scale. The problem is that the hardware is lasting longer than expected, and meaningful recycling volume does not yet exist.
Conversely, ~95,000 metric tons of nuclear waste in the US does not have permanent storage or recycling solutions, as of this comment, and there is no plan for long term storage or recycling. Nuclear generation is experiencing a negative learning curve; we keep spending more the more we attempt to build it.
(solar PV panels have a 25-30 year service life, at which point they will still produce power at ~80-85% initial rating, batteries have a 15-20 year service life, with sodium ion chemistries estimated to have up to 50 year service life assuming once daily cycling)

(nuclear power accounts for about 10% of electricity generation globally, as of this comment)
A nuclear plant about 50 miles from my house was closed 15 years ago. The spent fuel rods will be stored there indefinitely until a federal facility is built.
