The Role

Our Client is recruiting for a highly motivated and skilled Senior Nuclear Engineer to join their London based dynamic team. This role will sit within a multidisciplinary Engineering Office and will be responsible for the design, integration and research of nuclear systems for Floating Nuclear Power Plants (FNPPs) and Nuclear Merchant Ships (NMS). The role has a thermal-hydraulics and plant transient analysis focus, with supporting involvement in neutronics and shielding work.

Key Responsibilities

• Responsible for the development of engineering appraisal work for a range of different reactor technology projects.
• Development and V&V of thermal-hydraulics models for plant transient analysis.
• Take a senior role in the design and integration of nuclear systems in maritime applications, from defining requirements to preliminary design.
• Conduct technical evaluations, feasibility studies, and risk assessments for this discipline.
• Ability to understand, supervise, distribute and oversee analysis of important project criteria.
• Ability to understand and implement nuclear regulatory standards.
• Review and approve calculation packages on behalf of the company prepared by project teams and 3rd parties.
• Co-developing of neutronics models for core design and shielding.
• Working under a Systems Engineering Framework for the design of Floating Nuclear Power Plants and Nuclear Merchant Ships.
• Contributing to ongoing research and co-authoring peer reviewed publications for nuclear technology at sea.
• Authoring and reviewing of technical reports and documentation.
• Presenting work to internal and external stakeholders.
• Act as a mentor to junior engineers and naval architects and internship students.
• Ensure that all design and engineering work is performed, reviewed, checked and approved in accordance with engineering procedures or Project Quality Plans.
