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

    Nuclear Weapons Test and Evaluation Contractors

    Defined as: Companies that conduct, support, instrument, evaluate, or analyze physical testing for nuclear weapons, nuclear warheads, nuclear-specific components, or nuclear delivery systems.

  2. 02Criterion

    Stockpile Simulation and Certification Providers

    Defined as: Companies providing modelling, simulation, code development, computational science, or certification support for nuclear-weapons stockpile assurance or modernization.

  3. 03Criterion

    Dedicated High-Performance Computing for Nuclear Weapons

    Defined as: Companies designing, building, operating, or materially supporting supercomputing or high-performance computing systems dedicated to nuclear-weapons laboratories or stockpile simulation programmes.

  4. 04Criterion

    Nuclear Test Site and Range Support Providers

    Defined as: Companies operating, maintaining, or materially supporting test sites, ranges, facilities, instrumentation, diagnostics, or data systems used for nuclear-weapons testing or evaluation.

  5. 05Criterion

    Nuclear Missile and Delivery-System Test Support

    Defined as: Companies providing operationally relevant test instrumentation, telemetry, evaluation, or validation for nuclear missile systems or nuclear-specific delivery platforms.

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.

5 criteria
  1. 01Criterion

    Training and Operational Readiness Simulators

    Defined as: Companies providing training simulators, classroom tools, exercises, or operational-readiness simulations only. This excluded screen category is not being created per user instruction.

  2. 02Criterion

    General-Purpose IT or Computing Providers

    Defined as: Companies providing ordinary cloud, hardware, software, data centre, or IT services without a dedicated nuclear-weapons simulation, certification, or testing nexus.

  3. 03Criterion

    Civilian Nuclear Safety or Reactor Simulation

    Defined as: Companies simulating or testing civilian reactors, nuclear power plants, nuclear medicine, industrial radiography, or civilian radiation safety only.

  4. 04Criterion

    Arms-Control, Humanitarian, or Academic Impact Modelling

    Defined as: Organizations modelling nuclear risk, humanitarian effects, nonproliferation, arms-control verification, or policy scenarios without supporting operational weapons development or certification.

  5. 05Criterion

    Inert, Display, or Non-Operational Demonstration Testing

    Defined as: Companies testing replicas, inert devices, museum items, or non-operational mock-ups without connection to operational weapon performance, certification, or modernization.
