Commisioning Engineer Mechanical & Fuel Route

Role Overview

Working on a major nuclear power plant project the Commissioning Engineer within the Mechanical & Fuel Route Team is responsible for the planning execution and delivery of commissioning activities associated with mechanical systems supporting the fuel route and reactor operations of the plant. The role ensures that systems are commissioned safely compliantly and in accordance with project schedules regulatory requirements and operational readiness objectives.

Working as part of a multidisciplinary commissioning team the Commissioning Engineer will support the transition of systems from construction through testing commissioning and handover to operations ensuring that all activities are conducted to the highest standards of nuclear safety and quality.

Framework & Boundaries
Throughout the projects lifecycle the role of the Senior Commissioning Engineer will evolve combining
technical expertise with project management skills. At the early stages you will contribute to detailed
planning and preparation for the start of the Commissioning phase. Following this you will oversee the
execution of factory tests and commissioning tests as part of a team and analyse of the results to justify the
readiness of the HPC units to safely enter commercial operation.

As part of the role you will collaborate closely with Responsible Designers and project contract partners.
Together you will ensure compliance with a comprehensive set of commissioning documents that
incorporate technical test programs and safety justifications which will form an integral part of the
Commissioning Arrangements. Building strong collaborative relationships with designers contractors the
project delivery team site engineering and the plant operational organization will be crucial in
ensuring well-defined and controlled interfaces with the commissioning process.
