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.
We have worked with many companies within the nuclear supply chain, including:
Our 1D thermal-fluid code, Flownex, is used worldwide for modelling reactors, steam/power conversion and SCADA systems & control, including condensers, turbines and flow circulation. As part of a safety analysis, it can be used to calculate temperatures, pressures and time scales for a loss of cooling accident (LOCA) and identify pressure wave (water hammer) issues. Flownex is also ideal for Small Modular Reactor (SMR) applications, covering molten salt, gas, water and liquid metal and other coolant/ fuel types.
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.
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.
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.
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.
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.
