Nuclear

Our nuclear experience, use of industry-standard tools and supply of SQEP ensure we are well positioned to serve the needs of the nuclear industry throughout the UK. Our early growth during the 1980s was predominantly through nuclear services. We continue to actively support the industry, providing technical safety and reliability solutions in addition to design and engineering simulation for new build, small modular reactor (SMR) development and decommissioning applications.

Structural Analysis

We are very familiar with seismic, impact and other dynamic analysis as well as pressure equipment codes, including the analysis of glove boxes for nuclear decommissioning. We also offer fracture mechanics and fatigue capabilities.

For plant equipment, such as reactors, piping, materials handling and concrete protection barriers, we have carried out structural analysis projects for Babcock International subsidieries and other major companies. We also have experience undertaking third party assessment and reviews. Some of our work is undertaken in conjunction with civil & structural engineers within the Wilde Group who have significant nuclear design experience.

Through our knowledge of complex non-linear material behaviour, we also support manufacturers of high integrity forgings to the nuclear industry with micro-structural modelling services and software.

Ansys is used widely for nuclear applications. We have supplied FEA & CFD software and training services to the industry for over 20 years, including the additional CivilFEM for Ansys solution for undertaking specific nuclear-related analysis and  steel/concrete codes checking.

Geotechnical Analysis

With PLAXIS geotechnical FEA, we can accurately model soil-structure interaction when considering ground movement, installing the software at leading nuclear organisations and their supply chain. Thermal capabilities within PLAXIS enable underground temperature changes due to nuclear waste storage to be simulated.

RAMS Analysis & Risk Assessment

The nuclear industry is a major user of our ReliaSoft software for RAMS analysis and Probabilistic Risk Assessment (PRA). We run a dedicated training course concerning instrumentation and control safety systems within nuclear power plants, covering IEC61513, IEC 61226 and related standards. We have provided long term secondments of TRAM engineers to Sellafield on decommissioning projects.

Clients

We have worked with many companies within the nuclear supply chain, including:

AMEC Foster Wheeler Clean Energy | Assystem UK | Babcock (Dounreay Site Restoration) | Babcock (UKAEA Ltd)
Babcock (VT Nuclear) | EDF Energy | Esterline (Darchem Engineering) | Moltex Energy LLP | NDA (International Nuclear Services)
NDA (Sellafield Sites) | NIS Limited | Nuvia | Reviss UK | Sir Robert McAlpine | Springfield Fuels | Westinghouse

The course was highly informative and pitched to a level where all delegates could be included and feel part of the discussion. Lecturer had a good understanding of our environment and how the software package could be used in our industry.

EDF Energy

Very informative introduction to FE analysis in geotechnics. Good mix of theory and practical exercises.

Halcrow Group

I have found this course particularly useful. The content took me from a basic level of understanding to a point at which I feel comfortable using the software effectively. The teaching and exercises were very effective and interesting.

Sellafield

Everything about Wilde exuded first class quality from the moment [they] came to visit us to listen to our requirements. Then using Wilde’s extensive experience to provide Darchem with advice on the most cost and time effective options available for the analysis, whilst retaining accurate and robust results. The end report, results and the time scale in which this was achieved, further confirmed Wilde’s quality of service.

Esterline (Darchem Engineering)

Wilde Analysis have been a pleasure to work with during this project, responsive to requests, delivering on time and at reasonable cost and providing good guidance as to optimal ways forward.

Moltex Energy LLP

Many thanks for your contribution. By your diligence you have enabled us to proceed with confidence.

Reviss UK

We have now installed the kiln jet and operated at nearly double the throughput. I’d just like to say thanks for the invaluable work that you carried out in helping us to hone the design to the final version that was installed and worked impeccably from day 1. It saved us a lot of trial and error on the production line with associated losses that would have been incurred.

Springfields Fuels

The course has highlighted new and improved techniques to enable the company to be more efficient and flexible with presentation of the analysis and results.

Esterline (Darchem Engineering)

Excellent course! ... Brilliant refresher course for those who have not used FEA day to day and need to refresh on understanding of fundamentals.

NIS

Highly recommended. Excellent delivery, job well done!
