Independent Nuclear Safety Assessment (INSA) and Independent Safety Audit

Formal independent assessment and audit that gives authorised decision-makers a defensible view of nuclear safety documentation.

What we do

Formal nuclear safety decisions need an authoritative gatekeeper who can assess the evidence without ownership of the original work. We provide Independent Nuclear Safety Assessment and independent safety audit services for safety documentation, arrangements and supporting evidence.

Our assessments examine the safety case against applicable regulatory principles, challenge the basis for claims and controls, and identify whether the evidence is sufficient for the decision being requested. We make the basis for each conclusion clear, including unresolved issues and conditions that need to be carried forward.

The result is an independent, auditable assessment that supports approval authorities, licensees and duty-holders through formal safety sign-off and ongoing assurance.

Who this is for

Nuclear licensees, approval authorities, defence organisations, operators and duty-holders requiring formal independent safety assessment or audit.
