Job Description

General overview

The Radiological Protection Engineer ensures that the Buildings within client’s scope of responsibility meet the radiological protection requirements as required by the Nuclear Safety Authority. The Radiological Protection Engineer reports to the Team Leader and works alongside other Radiological Protection Engineers. They work closely with other engineering disciplines within client’s office and are part of the extended Radiological Protection team mainly based in the client’s office in Paris and Lyon.

Main activities
Based on radiological protection requirements and technical documents supplied by systems engineers (circuit operation, space requirement drawings, etc.), technical documents supplied by the architect engineer (location of sources of radioactivity) the Radiological Protection Engineer will:

Support the building design team for the detailed design of the nuclear island buildings
▪ Give advice to the designer regarding the radiological protection constraints (shielding needs, operational constraints, waste management, etc.) that could impact the Civil and Layout design of the building.
▪ Assess any civil and layout modifications that could impact the radiological and contamination zoning requirements of the building.
▪ Ensure that the design is consistent with UK context requirements.

Undertake studies and calculations relating to the spread of radiation
▪ From 3D model extracts, model the areas with PANTHERE software and assign various source terms (sources of radioactivity).
▪ Produce simulations for calculating the thickness of protection screens, depending on the reactor’s operating conditions, the geometry of the premises and the radioactive sources involved.

Provide analysis of the results and writing of technical reports
▪ Writes the radiation protection calculation reports in order to define the radiological zoning and contamination zoning of the buildings.
▪ Issues recommendations for protection screens:
– Defines the radiological classification of premises and systems.
– Defines the necessary protective devices and biological doors.
– Advises building leaders on the optimisation of premises.
▪ Supplies studies and recommendations to the layout teams.
