French nuclear giant scraps SMR plans due to soaring costs, will start over, page-106

The process for financial modelling multiple reactor/technology scenarios would follow common modelling principles.

1. Baseline cost estimates; CAPEX, OPEX, decommissioning cost, cost of capital, reg/leg cost.
2. Model on multiple scenario models including technology specific facts; factor by reactor number, size and technology basis to eliminate least efficient technology for geographic location, modelled economic assumptions, maturity curve, output, energy source input etc, (PWR, LWR, FBR or SMR)
3. Data collection and benchmarking modelling to known related projects
4. Sensitivity analysis - identify cost drivers and identified risk and assumptions.
5. Map confidence intervals
6. Model simulations - eg. Monte Carlo simulation
7. Cost benefit analysis - map estimate benefit profile
8. Comparative analysis to alternate energy technology financial models.

None of the above would require a decision on specific technology, these steps would be taken to provide to model a variety of scenarios to present the most suitable options to further explore through further market participation following formal decision making. 

No doubt you wont understand the above and will carrying on with more disinformation.
