F4N is a comprehensive supplier development and assessment programme designed to ensure businesses meet the high standards required by the nuclear sector.

It assesses capability across:

  • Quality management and process control

  • Health & safety and regulatory compliance

  • Leadership and business strategy

  • Cybersecurity and information management

  • Material traceability and documentation discipline

  • Workforce competence and training

  • Operational performance and continuous improvement

  • Culture, governance and organisational maturity

The assessment process is intensive, involving diagnostic reviews, site visits, improvement planning and verification audits.

Achieving F4N status means WKW has been approved by the Nuclear AMRC as a capable, and reliable, supplier to the nuclear supply chain.
