Currently, Societatea Națională Nuclearelectrica S.A. (SNN) is the sole producer of nuclear-generated electricity in Romania, through its CNE Cernavodă branch. Additionally, through its FCN Pitești branch, SNN manufactures CANDU-type nuclear fuel bundles used to power its own nuclear reactors.

The CNE (Nuclear Power Plant) Cernavodă branch operates the two functioning nuclear units based on CANDU technology and manages all SNN assets in Cernavodă (Units 1 and 2 in operation, Units 3 and 4 in the project phase). The two operational units (Units 1 and 2) each have an installed capacity of around 700 MW (706.5 MWe for Unit 1 and 704.8 MWe for Unit 2) and are among the most productive nuclear units in the world, based on capacity factor, out of over 440 units globally.
