Job Description

As a Thermal Hydraulics Analysis Engineer , you will join Derby team to support our activities within the Nuclear sector.

You will play a key role in supporting the LOCA fault analysis team, contributing to the delivery of detailed design and GDA Step 3 for advanced nuclear reactor systems.

This role focuses on Loss of Coolant Accident (LOCA) and steam generator tube rupture analyses, using system thermal hydraulics codes to support reactor safety cases and design validation.

You will be working within a highly regulated, safety-critical environment, contributing to the development and assessment of PWR (Pressurised Water Reactor) systems.

Location: Derby
On Site: 1 day / Remote
Clearance: BPSS
Experience Level: 5-10

Key Responsibilities:

Perform LOCA fault studies analysis, supporting ongoing safety and design assessments.
Conduct thermal hydraulics simulations using tools such as RELAP5-3D, CATHARE, or equivalent.
Analyse PWR water systems behaviour using 0D, 1D, or CFD modelling approaches.
Support analysis of steam generator tube rupture faults and related transient scenarios.
Provide technical input into reactor island system design and safety case development (GDA Step 3 E3S case).
Interpret simulation results to inform design decisions and safety justifications.
Collaborate with multi-disciplinary engineering teams to ensure alignment with nuclear safety requirements.
Contribute to technical documentation and safety case authoring where required.
Perform advanced thermal analysis and flow simulations using Flowmaster.
Carry out pressure drop, heat transfer, and system performance calculations.
Develop and validate models to support complex system designs.
Collaborate with cross-disciplinary engineering teams (mechanical, systems, safety, and integration).
Ensure all work is delivered to the highest technical and regulatory standards.
Contribute to design reviews, technical reports, and project milestones.

Qualifications

Required Skills:

Strong background in thermal hydraulics and fluid system analysis.
Experience with system thermal hydraulics codes (e.g. RELAP5-3D, CATHARE).
Knowledge of PWR technology and nuclear reactor systems.
Experience in fluid simulations, particularly thermal hydraulics (preferred over general thermofluids).

Required Qualifications:

Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, or related discipline or equivalent military experience.

Desirable Skills:

Experience in LOCA (Loss of Coolant Accident) analysis.
Familiarity with nuclear safety case development and regulatory frameworks.
Experience with CFD tools for thermal-fluid analysis.
Coding or modelling experience related to PWR system behaviour.
