Full-Time
Senior Nuclear Analysis Code Validation Engineer

Thermal Hydraulics | Verification & Validation (V&V) | VVUQ | Advanced SMR Programme

Location: Derby, Manchester or Warrington (Hybrid Working)

Salary: £53,800 - £66,500 + Bonus + £2,200 Flexible Benefits Allowance + Excellent Benefits Package

Morson are supporting a pioneering advanced engineering organisation as they continue to expand their specialist Performance & Analysis capability, delivering one of the UK's most innovative Small Modular Reactor (SMR) programmes.

This is a rare opportunity to join a specialist team responsible for the Verification, Validation and Uncertainty Quantification (VVUQ) of thermal hydraulic analysis codes used to support reactor design, safety case substantiation and plant performance.

Working at the forefront of advanced nuclear technology, you'll play a key role in developing confidence in the analytical tools and methodologies that underpin reactor safety and performance.

The Role

As a Senior Analysis Code Validation Engineer, you'll work within a specialist VVUQ team supporting the validation, verification and continuous improvement of thermal hydraulic analysis methods, models and software.

You'll collaborate closely with reactor performance, methods development, testing and safety teams, ensuring analysis tools are robust, validated and fit for application within a safety-critical environment.

The role offers exposure across reactor systems analysis, core thermal hydraulics, containment analysis and advanced modelling techniques used throughout the design and licensing lifecycle.

Key Responsibilities

Verification, Validation & Uncertainty Quantification (VVUQ) of thermal hydraulic analysis codes
Development and validation of analysis models against experimental test data
Benchmarking analytical predictions against large-scale thermal hydraulic test programmes
Supporting the development of analysis methodologies and modelling approaches
Quantification of modelling uncertainties using statistical and engineering judgement-based methods
Sensitivity studies and assessment of model assumptions
Development of Python-based analysis tools and automation
Working within Linux and High-Performance Computing (HPC) environments
Supporting reactor safety case substantiation and design validation activities
Technical leadership of analysis and validation activities across multidisciplinary teams

About You

We're interested in hearing from engineers with experience in one or more of the following areas:

Thermal hydraulics or fluid systems analysis
Verification & Validation (V&V)
Verification, Validation & Uncertainty Quantification (VVUQ)
Model validation against experimental data
Engineering simulation and analysis
Development of analysis methods, models or tools
Software verification and quality assurance processes
Uncertainty analysis and sensitivity studies
Python development for engineering applications
Safety-critical industries such as Nuclear, Defence, Aerospace, Oil & Gas, Process Industries or Power Generation

Desirable Experience

Experience with one or more of the following analysis codes would be advantageous:

RELAP
FLOMASTER
VIPRE
CTF
GOTHIC
Experience supporting safety cases, fault studies, transient analysis or reactor performance programmes would also be beneficial.

Qualifications

Degree qualified in Engineering, Physics, Mathematics, Computer Science or a related discipline
Chartered Engineer status, or working towards chartership, desirable

Salary & Benefits

Salary £53,800 - £66,500
Annual Bonus up to 12.5%
£2,200 Flexible Benefits Allowance
Excellent Pension Scheme
28 Days Holiday + Bank Holidays
Option to Buy or Sell Additional Leave
Private Medical Insurance
Life Assurance
Enhanced Family-Friendly Policies including IVF Support
Home Office Allowance
Flexible & Hybrid Working

Why Apply?

This is an opportunity to join a growing team of specialists working on one of the UK's most significant advanced nuclear programmes.

You'll help develop, validate and improve the analytical methods that underpin reactor safety, performance and licensing, while working alongside experts in thermal hydraulics, reactor systems and engineering analysis.

Please note that successful applicants will be required to undergo BPSS and DBS clearance checks
