Nuclear Power Generation

Identifies companies and other entities that own or operate civilian nuclear reactors used to generate electricity, including reactors in commercial operation and units in commissioning where the entity has accepted operational responsibility. Generating-capacity and revenue thresholds are client-policy overlays. Research or isotope reactors, nuclear-weapons facilities, suppliers without operational responsibility, plants solely in decommissioning, and announced projects without construction or commissioning activity are excluded.

How to read this definition

Inclusion criteria describe evidence that can establish this activity. Exclusion criteria identify circumstances that do not establish it on that basis alone. The evaluation remains connected to its taxonomy version and supporting evidence.

Can establish this activity

Included when supported

Evidence may support involvement when it matches one or more of these inclusion criteria.

5 criteria
  1. 01Criterion

    Include entities that directly operate civilian nuclear reactors generating electricity.

  2. 02Criterion

    Include owners of nuclear generating assets in commercial operation or commissioning where the owner has accepted substantive operational or economic responsibility.

  3. 03Criterion

    Include public, private, or mixed-ownership utilities with active civilian nuclear power generation.

  4. 04Criterion

    Include entities managing or operating civilian nuclear plants under concession, management, government, or public-private agreements.

  5. 05Criterion

    Include entities whose current operational or regulatory disclosures establish nuclear electricity generation, ownership, or operator responsibility.

Does not establish this activity on its own

Excluded on this basis alone

These circumstances do not establish this activity unless separate evidence also meets an inclusion criterion.

6 criteria
  1. 01Criterion

    Exclude entities whose only nuclear generating assets have permanently ceased operation and entered decommissioning; preserve historical involvement separately.

  2. 02Criterion

    Exclude entities engaged only in decommissioning, dismantling, remediation, or post-closure management without current nuclear generation.

  3. 03Criterion

    Exclude designers, constructors, developers, engineers, and technology suppliers without plant ownership or operational responsibility.

  4. 04Criterion

    Exclude fuel, component, maintenance, waste, and support-service suppliers without ownership or operation of a civilian nuclear generating asset.

  5. 05Criterion

    Exclude research reactors, isotope-production reactors, medical facilities, and other nuclear installations not used for electricity generation.

  6. 06Criterion

    Exclude announced or planned plants without active construction, commissioning, ownership of a committed project, or operational responsibility; project-development activity may qualify under Civilian Nuclear Power Plant Development and Engineering.
