Threat-informed. Consequence-driven.
Independent nuclear security advisory and assurance services.
NSAL provides independent nuclear security advisory and assurance, translating threat into practical, defensible protection.
We enable clients to deliver physical protection systems that are threat-informed, consequence-driven, and regulatory-aligned.
We provide independent assurance that nuclear security systems deliver the required protection effect against defined threats
The UK civil nuclear sector operates in a high-consequence environment where physical protection systems must demonstrably achieve defined security outcomes.
Controls may be well designed and implemented, but assurance often focuses on compliance rather than performance.
The critical question is:
Do security arrangements deliver the required protection effect against the defined threat?
NSAL provides independent, technically grounded assurance to answer that question with confidence.
WHAT WE DO
Assurance & Compliance
Independent, regulator-aligned, assurance that converts nuclear security requirements into defensible evidence, board confidence, and inspection readiness.
Threat & Risk Interpretation
We translate Design Basis Threats and risk into clear, actionable security decisions for leaders and delivery teams.
Intelligent Client Support
Independent intelligent client oversight that enables project design, justify, and embed security across the full project lifecycle.
Security Culture & Governance
We turn security culture into measurable leadership behaviours, workforce engagement, and board-level assurance.
Independent advisory and assurance - this is what NSAL does.
We do not deliver guarding or equipment installation or maintenance.
