Failure scenario in modern fission reactors is also benign. Reactors are designed to lock down to prevent any leaks.

We deploy solar PV capacity, this doesn't mean we actually get that much power from the deployments. Nuclear fission provides reliable, baseload power, and doesn't require huge battery arrays to compensate for the sun setting or winds calming.

Enough renewables are deployed annually to replace the global nuclear fission fleet, year after year, even when accounting for capacity factor derating (to make a like for like comparison). The race is over, and renewables (with batteries) won. If you can find someone unsophisticated to invest in a fission reactor that takes billions of dollars and 10-15 years to build, more power to you. There will be no need for it by 2035-2040 when it prepares to send its first kwh to the grid.

(and to stay on topic for this thread, geothermal is a component of this when geothermal potential exists, cost is competitive, and dispatachability is a requirement to push out fossil generation in concert with renewables, hydro, legacy nuclear, battery storage discharge, and demand response)

Nuclear is great, but it does require wheelbarrows of cash, and we don’t have a solution for waste products.
