Nuclear

We provide specialist engineering support to the UK defence nuclear enterprise, focusing on safety-critical systems, design authority, assurance and sustainment.

Our capability includes regulated engineering, non-conformance management, verification and validation, infrastructure support and through-life engineering. We operate within highly regulated environments, ensuring compliance with the stringent requirements of the Office for Nuclear Regulation (ONR) and the Defence Nuclear Safety Regulator (DNSR).

Case studies

Case study

Streamlining Engineering Compliance for UK Nuclear Submarines

Quest Global deployed a UK-based engineering team to support non-conformance management, engineering assessment, and design resolution activities for a nuclear submarine programme. The engagement improved maintenance throughput, enhanced platform availability, and maintained compliance with stringent nuclear safety and regulatory requirements.

Case study

Bridging the Legacy Gap for the UK Defence Nuclear Enterprise

Quest Global provided agile engineering support to modernise legacy dockyard infrastructure and accelerate readiness for future nuclear submarine defuel operations. By rapidly mobilising technical teams and introducing modern systems-thinking approaches, the programme improved operational efficiency, delivery alignment, and future scalability.
