For over 50 years, ABS Group has provided nuclear power generation facilities, suppliers and regulators with world-class engineering support and solutions, including probabilistic safety assessments, Seismic Qualification Utility Group (SQUG) walkdowns, extreme load engineering and independent technical assessments (ITA). Our rich heritage in the nuclear industry has enabled our experts to be at the forefront of developing methodologies that have acted as the industry standard for decades.
Our experienced multi-disciplinary team is comprised of civil, structural and mechanical engineers with decades of experience. Discover our engineering solutions and their ability to support nuclear facilities and their safety cases from initial design and construction to their operating lifetime and decommissioning.
ABS Group’s heritage in the nuclear industry started in the 1950s when EQE International pioneered risk assessment methodologies for the power industry. Since then, we have supported plants, suppliers and regulators including the Office for Nuclear Regulation (UK) and Nuclear Regulatory Commission (U.S.) with hundreds of probabilistic risk assessments, hazards and extreme load assessments, including seismic studies and retrofit designs. We have dedicated teams in Warrington, UK and several locations in the U.S. to ensure your local and international regulations are met.
ABS Group uses Finite Element Analysis (FEA) to study the behavior of structures, plants and equipment when subjected to normal (day-to-day) operating and design loadings and extreme hazards, such as seismic, weather, impact and blast loadings. These included linear and non-linear approaches and analysis methodologies.
Our multi-disciplinary team of engineers provides detailed design analysis and assessments for new buildings, structures, cranes or items of plant or equipment based on frequent 1-in-50 or 1-in-100-year events to support facilities to understand and overcome normal operating loads. Our team also reviews existing structures and plants subjected to new hazards or loadings that could affect or have an impact on the safety case.
Featured Loads:
Blast/Shock
Impact (including aircraft and other vehicles)
Seismic
Weather (wind, rain, snow, ice)
Flood
Fire

Our Extreme Loads and Structural Risk (ELSR) division includes engineers whose careers have focused on evaluating dynamic, explosion and thermal hazards for industrial and government clients. We use advanced simulation tools to model the dynamic response to both natural and man‑made hazards for infrequent 1-in-1000 and 1-in-10,000-year extreme events.
Extreme Loads:
Blast/Shock
Impact (including aircraft and other vehicles)
