  • Particularly for Instrumentation and Control, performing the analysis for defining the I&C Functional Requirements of the system and production of the I&C logic :
  • Writing of the Instrumentation and Control Functional Requirements
  • Writing of Detailed Functional Diagram (DFD)
  • Writing of the FTP (Functional test platform procedure) specifications
  • Analysis of the results of the FTP tests
  • Writing of P5 text (I&C logic description)
  • Writing of P6.x (alarms sheets, operating images, operating modes)
  • Particularly for mechanical design:
  • sizing of components e.g. pumps, fans, pipework, pressure relief valves, tanks
  • Perform thermal-hydraulic calculation and modelling with in house or commercial tools
  • Ensuring the 3D model is consistent with the intended system design
  • Formulate equipment specification and provide the data in respective database or data sheet
  • Support to procurement team in formulation of technical specification for contract documentation
  • Support to procurement team in technical surveillance of supplier documentation
  • Analysis and verification of input data, requirements, and lessons learnt from other stations
  • Engage proactively with all stakeholders around the system to ensure the delivery of a product meeting the requirements set by all disciplines (layout, civil, hazard, nuclear safety, environment, configuration management, procurement …)
  • Contribute to topics around good practises, innovation, improvement of processes, and quality
  • Participate in experience sharing activities within the discipline
  • Management of modifications related to the system including:
  • Managing requests for modifications to system(s) issued by various external parties by producing specifications and following engineering cycle (I&C and/or mechanical design changes specifications)
  • Analysis and verification of the applicability of these modifications and challenging them as appropriate
  • Developing technical solutions and presenting them to the client to help resolve technical issues (technico-economic optimisation approach)
  • Utilising the electronic Engineering Change Management tool
  • Support to System Coordinator for relevant building:
  • Producing and updating component datasheets for handovers with detailed designers
  • Producing and updating P&IDs with all relevant design changes for handovers with detailed designers
  • Liaising with other stakeholders through participation at kick off meetings, gate reviews etc relevant to the system.

Essential Requirements:

  • Mechanical or Chemical Engineering degree or equivalent qualification
  • Knowledge of Instrumentation and Control design
  • Experience of producing design documentation and Test Specifications
  • Knowledge of nuclear system design, thermal-hydraulic calculation and modelling
  • Working knowledge of fluid mechanics, heat transfer and thermodynamics
  • Knowledge of PWR or AGR power station design and system


Desirable Requirements:

  • Knowledge of EPR design principles and Safety Classification
  • Understanding of Safety Case construction and Nuclear Safety requirements placed on systems
  • Knowledge of UK licensing requirements and its application within the HPC project
  • Familiarity with Human Performance techniques
  • Experience of working on an operating plant or on an industrial site
