Nuclear, Defence and Power

In the Nuclear, Defence and Power sectors, failure is not an option. The integrity of built assets is a matter of national security and public safety.

From the decommissioning of legacy nuclear sites to the maintenance of active naval bases and power stations, the requirement is for absolute structural reliability.

 

Engineering for High-Hazard Environments

In sectors where failure is not an option, Structural Repairs provides the certainty you need. We specialize in the remediation of critical assets within the nuclear, defence, and power generation sectors—environments defined by strict regulatory oversight and zero tolerance for risk.

Our methodologies are rigorously aligned with the safety standards set by the Office for Nuclear Regulation (ONR), ensuring that every repair we undertake contributes to the safety case and operational continuity of your facility.

Innovation in Hazardous Environments

When human access is limited by radiation or security protocols, standard repair methods fail. We innovate to bridge the gap between structural necessity and operational safety.

  • Remote & Robotic Delivery: We have developed methodologies for the remote application of repair mortars and coatings using robotic systems. This allows us to repair containment vessels and waste storage ponds while keeping our operatives in safe, low-dose areas, adhering to ALARP (As Low As Reasonably Practicable) principles.
  • High-Density Shielding Repair: Standard concrete does not stop radiation. We have formulated and tested bespoke high-density heavyweight concretes (using magnetite or barite aggregates) that allow us to repair shielding walls without compromising their radiation attenuation properties.

Environmental Jeopardy & Carbon Efficiency

The Decommissioning Challenge The environmental jeopardy in this sector is unique. Demolishing a nuclear facility or a hardened defence asset is exceptionally carbon-intensive and generates vast quantities of waste that requires specialist disposal. The “embodied carbon” in a reinforced concrete reactor building or a submarine dry dock is immense.

The Low-Carbon Life Extension We champion “Safe Store” and life extension strategies. By repairing and protecting the existing fabric, we avoid the colossal environmental cost of new construction.

Asset Longevity

Our cathodic protection systems can extend the life of cooling water intakes and reinforced concrete structures by 50+ years, aligning with long-term decommissioning or operation strategies.

Containment Assurance

By sealing leaks in bunds and storage ponds, we prevent environmental contamination, protecting the local ecosystem from radiological or chemical harm.

Material Efficiency

We utilise geopolymer mortars and low-carbon cement replacements where specification allows, reducing the carbon footprint of the repair itself.
