NUCLEAR STRUCTURE

Rigorous and traceable nuclear structural engineering expertise

The success of any intervention in a nuclear environment depends above all on mastering structural, regulatory, and operational constraints. INGEFORCE deploys structured engineering analysis to justify the structural integrity of facilities during maintenance, modification, or decommissioning phases. In confined environments, ATEX zones, or co-activity contexts, we design fully documented, audit-ready solutions that are practical for on-site implementation and compliant with industry requirements.

Verification of Nuclear Structures
Inspection of concrete and steel structures, load-bearing capacity analysis, and justification under operational and accidental loads.
RCC-CW Calculation Notes
Design sizing and verification in accordance with applicable codes and standards, with formalized assumptions and full traceability.
Modifications to Existing Structures
Addition of equipment, load reassessment, and structural reinforcements in constrained environments.

Interventions in ATEX & Confined Environments
Consideration of access constraints, safety requirements, and multi-contractor co-activity.
Reinforcement & Envelope Adaptation
Strengthening and adaptation studies for structural envelopes and secondary structures.
Operational & Auditable Deliverables
Structured technical documentation, clear executive summaries, and documents tailored to inspection bodies and nuclear industry quality requirements.

Structural integrity : guaranteeing the safety of your Basic Nuclear Installations (BNI)

Any modification in a nuclear environment affects the structural balance of a facility.
We intervene to verify, justify, and secure these changes in compliance with applicable codes and standards, as well as operational constraints.

Operational constraints management

Maintenance during operation, multi-contractor co-activity, restricted access, confined environments, or ATEX zones: we integrate these parameters from the calculation phase to ensure the feasibility and safety of interventions.

Applicable codes and RCC-CW calculation notes

Our design calculations and verifications are based on the applicable technical frameworks, notably RCC-CW – Design and Construction. Each assumption is formalized, justified, and fully traceable.

Documentary traceability and insurability

Our calculation notes and technical files are structured to meet the documentation requirements of the nuclear industry. Clear, auditable, and operational deliverables designed for inspection bodies and project stakeholders.

Nuclear environments: complying with strict regulatory frameworks

Structural interventions in Basic Nuclear Installations (BNI / INB) are subject to enhanced technical and documentation requirements, under the supervision of the Autorité de Sûreté Nucléaire.

Any structural modification, reinforcement, or equipment addition must be justified in accordance with applicable codes and standards, and integrated within a rigorous framework of safety and traceability.

INGEFORCE supports you in securing your structural studies in nuclear environments, ensuring deliverables that are fully operational and compliant with industry expectations.

APPLICABLE CODES & STANDARDS

Design in accordance with nuclear industry frameworks. Studies carried out under RCC-CW and BNI (Basic Nuclear Installation) requirements.

DOCUMENTATION REQUIREMENTS

Full calculation traceability. Structured calculation notes, formalized assumptions, and operational deliverables.

NON-COMPLIANCE RISKS

Insufficient justification can halt a project. Delays, corrective requirements, and insurance risks.

OUR APPROACH

A clear and fully justified structural assessment. Verification, design sizing, and an audit-ready technical dossier.
