Scott Williamson-Owens
Principal - Head of Simulation and Modelling
Scott has 30 years’ nuclear science and engineering experience, working across the entire nuclear fuel cycle, with a focus on modelling support to plant/process design and optimisation with strategic & safety decision making. Part of Scott's role includes providing expert technical advice to a range of site and engineering customers and served on several UK industry technical committees – particularly in nuclear decommissioning and waste management. Scott has a wide range of experience in working on international projects including US, Canada, EU, Iraq, Japan & Australia.
He has a long and distinguished working involvement with academia and national labs, with a track record of managing work through from low TRL innovation and research to practical application within industry. Scott has worked on some of the most complex and intractable problems in the nuclear industry including high-profile issues, such as: Sellafield effluent management, wet sludge silo stores and waste vitrification facilities; Westinghouse MOx; Magnox waste and pond activity management; Dounreay site decommissioning and waste management site operations. Most of work has related to hazard and risk reduction, including cost management – with an international reputation for excellence, demonstrated by his customer base.
Most recently, Scott has built a strong (and becoming world-recognised) team in the area of process and operational models – combining the capability to optimise program-level and operational processes within the same tool; providing tension and balance between engineering throughput at the unit process level and operational management requirements and constraints (such as budget and available resource).
Recent tasks Scott has worked on:
- Led project to deliver site programme and operational modelling solutions for the Dounreay site
- Built UK-NNL plant and optimisation team from disparate modelling teams and grew to 20+ strong profitable capability.
- Developed the model used to predict and manage effluent discharges from the Sellafield Site, used by site and UK regulators.
- Published over 20 peer reviewed journey papers, book chapters, patents and 50+ key industry advisory reports.
