Engineering challenges in Nuclear & SMR

Technical and regulatory pressure points in this sector.

Regulatory Approval Complexity

UK nuclear projects must satisfy the Office for Nuclear Regulation (ONR) Generic Design Assessment (GDA) process. Engineering documentation requirements are significantly more demanding than conventional construction.

Structural Integrity at Nuclear Grade

Seismic design, nuclear-grade concrete specification, and independent structural verification are required for all safety-significant structures under ONR Safety Assessment Principles.

OT Security at Nuclear Grade

Nuclear control systems require security classification and assurance approaches that go beyond standard NIS2 requirements — aligned to IAEA Nuclear Security Series and ONR cyber security guidance.

Key regulations

Regulatory frameworks applicable to this sector.

  • ONR Safety Assessment Principles
    UK nuclear regulator requirements for all safety-significant structures, systems, and components.
  • NIS2 Directive
    Nuclear operators are within NIS2 scope — cybersecurity obligations apply in addition to sector-specific requirements.
  • Euratom Treaty
    EU framework governing nuclear energy — applicable to UK-EU nuclear cooperation and materials trade.
  • Nuclear Safety Directive 2014/87/Euratom
    EU directive establishing common nuclear safety framework — applicable to civil nuclear operators.
