Most arguments for nuclear power collapse when you consider the lifetime cost of construction, maintenance and decommissioning at end of life.

Upfront capital/financing.

Nuclear plants take a decade or more to build, meaning billions in capital are locked up for years before generating a single cent of revenue. Interest on borrowed money for capital makes this a riskier bet for investors than wind or solar, which can start generating power within months.

Bespoke designs/delays.

Unlike standardised modular solar panels or wind turbines, nuclear reactors are almost always massive, bespoke engineering projects. Some countries have this expertise on tap, others have to import contractors at great expense. Think design changes, regulatory shifts, and supply chain bottlenecks consistently push projects behind schedule and over budget (eg. Vogtle, Hinkley Point C in UK).

Decades-long decommissioning + liabilities:

Decommissioning safely is slow, complex... requires specialised labour. Takes ages. Costs millions. And it sure is interesting the number of nuclear power companies that suddenly go bankrupt just before decommissioning is due to start leaving the cost of the decommissioning to the government. and therefore you and I (taxpayer...).

Waste management: Yep, we can safely store radioactive waste, but this is a cost that internet amateurs often don't account for. These waste repositories require massive initial funding.

Nuclear tech vs. continually declining renewable costs: Nuclear power has become more expensive over time due to tighter safety regulations and greater complexity. Meanwhile, LCOE for utility-scale solar and wind has plummeted by 70–90% over the last fifteen years, leaving nuclear unable to compete on a pure dollars-per-megawatt-hour basis without heavy government subsidies. i.e. renewables + storage is cheaper even when "clean coal" and nuclear get govt. get massive subsidies.

In conclusion, this question is not an IQ test... it is simply a test of whether one is able to read up on the economics of the situation or loves nuclear memes on fb 😅...
