Data provenance

Source of the capacity and fuel values:

capacity: GEM Global Nuclear Power Tracker September 2025 unit-status sum (cancelled); fuel: GEM GNPT

In context: how this plant compares

Technically it is described as boiling water reactor. Its current lifecycle status is “Cancelled” — so it is not yet, or no longer, generating at full output. Nuclear plants split uranium to raise steam with no direct CO₂; they run as steady baseload with very high capacity factors and the longest operating lifetimes of any thermal plant.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
