Retractable Tunnels for Nuclear Power Stations

Enhancing Safety and Efficiency

When it comes to nuclear power generation, safety, precision, and operational efficiency are non-negotiable. Every process, from routine maintenance to critical infrastructure upgrades, demands controlled environments that protect personnel, equipment, and the integrity of the site. As the energy sector evolves and nuclear facilities undergo refurbishment and life-extension projects, adaptable temporary structures are becoming essential tools. This is why retractable tunnels have a part to play at nuclear power stations.

At Stretch Structures, our retractable tunnels are increasingly being deployed at nuclear power stations, offering robust, flexible, and rapid to install solutions that meet the unique challenges of highly regulated environments.

Why Nuclear Power Stations Need Retractable Tunnels

1. Controlled Environments for Sensitive Operations

Nuclear sites require strict management of dust, debris, and weather exposure. Retractable tunnels create sealed, weatherproof pathways and work zones, allowing teams to carry out inspections, decontamination, and component transfers without contamination risks.

2. Protection from the Elements

Weather is unpredictable year-round. Retractable tunnels provide immediate shelter from rain, wind, and UV exposure, ensuring work can continue safely and on schedule, even in adverse conditions.

3. Safe Transfer of Materials and Equipment

Large components, such as turbines, switchgear, or specialised tools, often need to be moved between buildings or into containment structures. Our tunnels create protected transit routes that help maintain cleanliness standards and protect sensitive equipment.

4. Rapid Installation with Minimal Disruption

Nuclear power sites operate under strict scheduling and security controls. Our retractable tunnels can be installed quickly and customised to fit existing infrastructure, reducing downtime and allowing work to proceed without major site modifications.

5. Durable, Compliant, and Customisable

Stretch Structures’ retractable tunnels are engineered to meet the stringent standards expected in nuclear environments.

Benefits include:

  • Flame-retardant, industrial-grade PVC fabrics
  • Galvanised steel or aluminium frames
  • Custom height, length, and colour options
  • Optional flooring, HVAC systems, and access points
  • Integration with radiation-controlled zones or secure transfer systems

Applications at Nuclear Power Facilities

Retractable tunnels are currently being used across the energy sector for:

  • Maintenance bays and temporary workshops
  • Walkway protection for staff during outages
  • Encapsulation of high-risk or weather-sensitive tasks
  • Temporary cover during turbine hall operations
  • Link tunnels between modular buildings
  • Shielded pathways for specialised equipment transfer

Their flexibility means they can be deployed temporarily for shutdowns or left in place as semi-permanent structures.
