Actemium delivers high‑integrity engineering solutions for nuclear defence programmes, supporting some of the UK’s most sensitive and strategically important facilities. We have extensive experience operating within secure, highly regulated environments, including long‑term programmes where safety, assurance and reliability are paramount.
Nuclear defence demands engineering partners that can operate with rigorous security, robust assurance, and uncompromising delivery discipline. Actemium supports defence clients and their delivery partners with high‑integrity engineering across infrastructure, facilities, containment and safety‑critical control systems – where configuration control, information governance and secure delivery are integral to success.
Our nuclear defence support typically includes:
- High‑integrity containment and process enclosures – engineering of containment and glovebox‑type systems, supporting controlled operations, maintainability, and integration of utilities, ventilation and monitoring/control architectures.
- Safety‑critical and mission‑critical control systems – design and build of control panels and safety systems, implementation and commissioning, plus lifecycle support – aligned to functional safety expectations where applicable.
- Secure industrial automation and cyber-aware delivery – automation engineering that prioritises reliability, consistency and compliance in regulated environments, informed by experience across other high‑assurance industries.
- Resilient power and packaged infrastructure – LV switchgear, MCCs, generator control and containerised electrical rooms / e‑houses to reduce onsite disruption and accelerate deployment, with factory build and test in the UK.
For customers, the value is straightforward: reduced delivery risk, clearer interfaces, and engineering outputs that stand up to scrutiny – without losing pace. Where security considerations apply, we align delivery to the applicable controls and assurance expectations, including Cyber Essentials Plus and security cleared personnel where required.
