Energy, Society, and the Environment/Swapping Coal for Nuclear Power
Financial Cost[edit | edit source]
In "Carbon emissions and costs associated with subsidizing New York nuclear instead of replacing it with renewable" Felix Cebulla and Mark Jacobson break down the financial costs of maintaining a nuclear subsidy for New York state over swapping entirely to wind or swapping to mixed wind/photovoltaic (PV) systems.
(Measured in 2014 USD) They estimate the financial cost of maintaining current nuclear power plants from 2016 to 2050 at $32.4 billion (USD).
However they measure the cost of swapping to other systems at: Entirely to wind farms at $24.5 billion A mixed wind/PV system to either $31.6 billion if 25% of power is supplied by rooftop PV's A mixed wind/PV system $25.8 billion if all PV power is supplied by utility companies.
Alternatively in "Evaluating the Cost, Safety, and Proliferation Risks of Small Floating Nuclear Reactors Michael Ford, Ahmed Abdulla, and M. Granger Morgan break down the financial cost of having small offshore nuclear plants (fSMR) versus the costs of having land based nuclear power plants as well as what the costs would be if they were built by the US military.
For an SMR with an output of under 300 Mega-Watts: The cost to construct a fSMR using commercial cost it would be approximately $620 Million. The cost to construct a land based SMR of the same scale it would be approximately $760 Million. If the fSMR were built using specifications created by the US military (MILSPEC) it would cost (according to their calculations) over $1.4 Billion .
