Steam Dump Isolation Valve Control Panel

Steam dump systems, and their associated isolation valves, play a key role in managing reactor conditions during transient events and operational adjustments.

Maintaining the performance and reliability of these systems is essential for both safety and operational continuity. As part of ongoing lifecycle management, EDF Energy required engineering support to progress the development of an updated control solution aligned with modern operational and compliance expectations.

The requirement was not simply to deliver engineering input, but to do so within a constrained commercial and technical framework.

Key challenges included:

• Supporting the development of a safety-critical control system without disrupting ongoing operations
• Ensuring alignment with existing plant systems, standards, and regulatory expectations
• Delivering at pace to meet programme demands

This required a delivery approach that combined technical precision with flexibility and clear accountability.

AMS Nuclear deployed an experienced lead engineer to provide targeted design and engineering support for the control system development. Rather than applying a broad or generic solution, the team focused on providing the specific expertise required to move the project forward efficiently.

The approach included:

• Supporting the development of an automatic control system for the steam dump isolation valve
• Ensuring compatibility with existing control architectures and plant interfaces
• Applying nuclear industry best practice for design governance, documentation, and traceability
• Working within EDF’s established framework agreement to maintain consistency in quality and compliance

The project was delivered through a streamlined and controlled support model, designed to align with both technical and commercial requirements.

Key elements of delivery included:

Design & Engineering Integration
Direct involvement in system development ensured that engineering outputs were aligned with functional and operational requirements from the outset.

Quality Assurance & Compliance
All activities were conducted in accordance with EDF’s framework agreement and nuclear QA processes, ensuring appropriate oversight and documentation.

Collaborative Working
Close engagement with EDF stakeholders enabled efficient communication, rapid decision-making, and alignment with site-specific needs.

This project highlights how targeted engineering expertise can deliver measurable value in a highly regulated environment, without the need for large-scale mobilisation.

Key learning points include:

• Focused Expertise Delivers Impact
  Deploying the right engineering capability at the right time enables efficient progress on complex systems.
• Framework Alignment Accelerates Delivery
  Working within established client agreements reduces onboarding time and ensures immediate compliance with required standards.
• Transferable Across the Fleet
  The approach used is directly applicable to similar control system developments and upgrades across the UK nuclear fleet.

This project demonstrates AMS Nuclear’s ability to deliver clear, accountable and technically robust solutions – supporting safe, reliable operations across critical nuclear infrastructure.
