EDF EPR Engineering UK (EPR-E) is a subsidiary of Edvance, which is a joint venture between EDF and Framatome, established in 2018 in charge of the design and the realisation of nuclear islands for new projects in France and worldwide.
At HPC we are building two new nuclear reactors, the first in a new generation of nuclear power stations in the UK providing low carbon electricity for around six million homes.
For the SZC Project, work on the replication strategy and some early design studies are already underway and being delivered and managed from both France and UK.
We are looking to recruit for the role of JDO Mechanical Calculation Engineer.
The Mechanical Calculation Engineer position focuses on supporting field design activities for the piping discipline within the HPC project. The role involves managing interfaces with multiple disciplines and resolving piping engineering issues encountered during on-site installation of pipework and associated supports. The engineer will ensure compliance with nuclear industry standards and project milestones while maintaining EPR-E procedures. The main tasks will be the following:
Data Collection and Analysis:
Gather input data, analyse/update hypothesis notes, and prepare detailed loading description reports for piping systems and supports.
Mechanical Stress Analyses:
Perform piping flexibility calculations, piping support calculations, and finite element analysis (FEA) to address installation and operational issues using PipeStress, RSTAB & ANSYS software’s.
Conduct dynamic analysis of nuclear structures and components under seismic, thermal conditions (pseudo-static/dynamic), including frequency analysis and structural rigidity assessment.
Design and calculate anchorages (Pre/Post Embedded Plates using VerifPlatines software or Hand calculations), welds, and bolted connections for piping and equipment supports.
Design and Modification:
Propose proportionate modifications when sizing criteria are not met.
Verification and Quality Control:
Review calculation notes and guide drawings subcontracted to external companies.
Check steel structures (e.g., base frames, racks), supports for electrical cabinets, batteries, boxes, main cable trays, instrumentation (pressure/temperature/level sensors), and HVAC support systems (for ducts, chillers, condensers, centrifugal fans etc..).
Support and assist Equipment Department to verify calculation notes for various equipment such as Pumps, Valves, Flanges, Heat exchangers, Tanks, and Pressure Vessels.
Technical Support and Documentation:
Provide technical clarifications to NNB and respond to site requests (RFI, FCR, NCR).
Offer technical support to others disciplines for a wide range of calculations (handling systems…)
Prepare and review technical documentation to support design and installation activities.
Collaboration:
Collaborate with installation contractors, civil works (CW) interfaces, and other disciplines
