Extremely so.
Every estimate given that shows how cheap it is ALWAYS ignores "hidden" costs.
yes it is very expensive.
Uranium is more expensive, but the kWh in a nuclear power plant is more cheaper.
Nuclear fusion rocket technology is too expensive to use as a means for power production.
Some common cons of nuclear power include the risk of accidents leading to radioactive leaks, the long-term storage and disposal of radioactive waste, and concerns about nuclear proliferation and the potential for nuclear weapons development. Additionally, nuclear power plants can be expensive to build and decommission.
Extracting energy from nuclear fuels is more expensive than extracting energy from fossil fuels.
No one has found a way to get rid of nuclear wastes, there is a lot of security dealing with nuclear power, an accident at a nuclear reactor can be dangerous for miles around and for years to come. Except for hydrogen bombs, nuclear fusion power has not been harnessed by people for more than a few seconds. Considering that all a nuclear (fission) power plant does is to boil water and turn it into steam, there are better ways of making electricity than nuclear power (except for submarines and aircraft carriers). Remember Three Mile Island and Chernobyl? That's why nuclear power is so expensive.
Nuclear power plants require high upfront capital costs for construction, maintenance, and decommissioning. Strict safety and security measures, complex regulatory requirements, and long project timelines also contribute to the high costs associated with nuclear power. Additionally, challenges related to radioactive waste disposal and public perception can further increase expenses.
They are expensive to build but relatively cheap to run because the fuel costs are lower.

All types of power are going to be more expensive than in the past, we shall have to get used to it.
Gas turbine power is more expensive per kilowatt-hour than nuclear power due to the higher fuel costs associated with natural gas compared to nuclear fuel (uranium). Nuclear power plants also have lower operating and maintenance costs and have a longer operational life, resulting in lower overall costs per kilowatt-hour. Additionally, nuclear power plants typically benefit from government subsidies and incentives that help lower the cost of production.
Nuclear is about the same as fossil fuel in total costs, but more expensive to build the plant. Solar and wind power are more expensive and have to be subsidised to make them economic for power companies to use
