Honorable Accountant.
I am primarily an Oil & Gas person but since I am also interested in “Energy” in general, I know how to get at the latest information about the Economics of Nuclear Power.
The “Fuel cost” only of nuclear energy is normally less than 0.50 cent (75 paisa) per unit but capital outlay and other costs are very high. To get a true comparison; power engineers have developed the concept of ‘Levelized cost of energy" (LCOE) which is the average total cost of building & operating the plant over its lifetime as per unit of the total electricity production over the plants operating life.
Since all the info is from another source with very little input from me, I am only copying below for what is relevant to your query. The detailed info is available at:
Nuclear power is cost competitive with other forms of electricity generation, except where there is direct access to low-cost fossil fuels. In assessing the economics of nuclear power, decommissioning and waste disposal costs are fully taken into account.

“Economics of Nuclear Power”
(Updated March 2020)
- Nuclear power is cost competitive with other forms of electricity generation, except where there is direct access to low-cost fossil fuels.
- Fuel costs for nuclear plants are a minor proportion of total generating costs, though capital costs are greater than those for coal-fired plants and much greater than those for gas-fired plants.
- System costs for nuclear power (as well as coal and gas-fired generation) are very much lower than for intermittent renewables.
- Providing incentives for long-term, high-capital investment in deregulated markets driven by short-term price signals presents a challenge in securing a diversified and reliable electricity supply system.
- In assessing the economics of nuclear power, decommissioning and waste disposal costs are fully taken into account.
- Nuclear power plant construction is typical of large infrastructure projects around the world, whose costs and delivery challenges tend to be under-estimated.
The OECD Nuclear Energy Agency’s (NEA's) calculation of the overnight cost for a nuclear power plant built in the OECD rose from about $1900/kWe at the end of the 1990s to $3850/kWe in 2009. In the 2015 report
Projected Costs of Generating Electricity, the overnight costs ranged from $2021/kWe in South Korea to $6215/kWe in Hungary. For China, two comparable figures were $1807/kWe and $2615/kWe. LCOE figures at a 3% discount rate range from $29/MWh in Korea to $64/MWh in the UK, at a 7% discount rate from $40/MWh (Korea) to $101/MWh (UK), and at a 10% rate $51/MWh (Korea) to $136/MWh (UK).

Comparing the economics of different forms of electricity generation.
In 2017 the US EIA published figures for the average levelised costs per unit of output (LCOE) for generating technologies to be brought online in 2022, as modelled for its Annual Energy Outlook. These show: advanced nuclear, 9.9 c/kWh; natural gas, 5.7-10.9 c/kWh (depending on technology); and coal with 90% carbon sequestration, 12.3 c/kWh (rising to 14 c/kWh at 30%). Among the non-dispatchable technologies, LCOE estimates vary widely: wind onshore, 5.2 c/kWh; solar PV, 6.7 c/kWh; offshore wind, 14.6 c/kWh; and solar thermal, 18.4 c/kWh.
