Nuclear Fuel & Electricity Cost Calculator

made by AtomicBlender ↗

LCOE+ Calculator

LCOE+ extends the classic levelized cost of energy view to include construction draws, fuel logistics, refurbishments, inventory carrying, and debt service – everything needed to see the full cost stack of a nuclear project.

This calculator is in beta and may contain inaccuracies. If you find something that looks wrong or broken, please let us know.

Reactor Preset

Pre-filled with typical parameters for the selected reactor design.

A large light-water PWR rated around 1,100 MWe per unit. Typical of most reactors worldwide.

Quickly stress-test the plan by applying percentage overruns/underruns to capex and shifting the construction schedule. Manual edits inside the Construction panel reset these adjustments.

Simulate cost growth or savings relative to the baseline estimate.
