Capital Costs

This techno-economic study, using the Desalination Economic Evaluation Program developed by the International Atomic Energy Agency, shows that by 2030, China will have the capacity to produce 23.1 billion cubic meters of water annually, at $0.86/cubic meter, as a coproduct of electricity generation through nuclear power, provided the country favors desalination over water diversion. The authors argue that this policy is more economical and less risky than diversion over the long term.

In these PNAS proceedings, the authors use interviews with 16 experts to evaluate two small modular reactor (SMR) designs based on engineering-economic assessment experiences. They provide estimates of the overnight cost and construction duration for five reactor-deployment scenarios that involve a large reactor and two light water SMRs.

This journal article reviews historical trends in the construction costs of reactors worldwide. The authors discuss the impact of the learning curve on costs and find that in some national environments costs have plateaued whereas in others they have decreased.
This journal article provides background on nuclear cogeneration for district heating, describes a techno-economic model with which to evaluate its application and applies the model to a proposed implementation for district heating in Paris. The cost modeling limits itself to heat transport lines. The policy context is built on a government mandate to alter the share of production derived from nuclear.
This market report identifies resources, commodities and manufacturing capacity as principal cost drivers for nuclear power plants. The high costs reported result in overnight generation rate estimates of $1,200 per kilowatt (kW) to $4,540/kW and total operation costs that range up to $8,081/kW. The authors report projects future increases in construction costs due in part to an average cost overrun of 207 per cent. The authors discuss some policies that could be critical in overcoming cost barriers.

This journal article investigates the costs of stand-alone renewable hybrid power plants on a Greek island and compares them to the cost of the currently used fossil-fuel-based conventional plant. The author shows that the higher cost of electricity of such a remote region can increase the competitiveness and promote the wider incorporation of technologies based on renewable energy sources.

This study was commissioned to provide an independent “outside-in” estimate of the cost and schedule risks of nuclear waste storage projects. The authors analyse cost and schedule risk profiles of 22 completed nuclear waste storage projects, 194 nuclear new builds and 31 underground mining projects.
