Tim Soetens

Tim joined Eden NE in 2012, bringing in experience from working for the Belgian waste management agency ONDRAF/NIRAS and Belgian waste producers.  He has more than 20 years’ experience related to radioactive waste and nuclear engineering.  His main expertise lies in simulation, modelling and data analysis.  Tim is an experienced user of several modelling tools, including PC-CREAM 08 and the ERICA assessment tool.  He also developed bespoke models using GoldSim, Excel and Scilab.  Tim undertook assessments related to aqueous and aerial discharges, migration in groundwater, human intrusion and impacts to non-human biota, in support of Environmental Safety Cases, Article 37 Submissions and environmental studies for various UK based clients, such as LLWR, Sellafield, Magnox and Dounreay.  Since 2016, Tim has been working extensively with the LLWR’s inventory team to develop a Repository Derived Inventory in cooperation with waste producers.  Tim is a certified RWA and a Chartered Radiation Protection Professional.

 

 

 


Nick Mitchell

Eden_NXM (200x200px)Nick has over 32 years’ experience providing a range of scientific modelling solutions covering radioactive material in the biosphere, radiological assessement, rail infrastructure and municipal waste management activities. He has substantial experience supporting nuclear regulators having contributed to UK implementation of the BSS Directive in UK legislation and provided support to the development of predictive models used to assess radioactive discharges. Nick also helps waste contractors procure and assess long-term management contracts through the development of predictive models for waste flows and process performance. He has also produced models to simulate and assess the uncertain deterioration of rail infrastructure for Network Rail and London Underground. Nick provides support to clients in development and submission of environmental safety cases for the near surface disposal of radioactive waste and associated Article 37 submissions.  He is currently a contributing author to an IAEA publication on the behaviour of Uranium in the environment.


Paul Tulip

Paul has 10 years’ experience in mathematical and computational modelling, including the development of scientific software to model material properties. Since joining Eden Nuclear and Environment, he has applied these skills to develop and apply radiological dose models and models of radionuclide transport in the environment. He has experience in using models to perform radiological risk assessments, and to support the development of environmental safety cases and derivation of waste acceptance criteria for radioactive waste disposal facilities. Paul has supported the development of the LLWR’s Environmental Safety Case, including an application to vary the LLWR’s Permit. As part of these activities, he co-authored and edited a recent Article 37 submission for LLWR, assessing the LLWR’s radiological impact on neighbouring EU states. He is currently developing a BAT study into the disposal of stored wastes at the LLWR. He has also contributed to the development of a conceptual model to understand coastal and marine particles.

 


Tim Slater

Eden_TPS (200x200px)Tim obtained an undergraduate masters in Mathematics and Physics from the University of Warwick, before moving to Manchester, where he got a PhD in Atmospheric Science.  Tim joined Eden Nuclear and Environment in 2015, and has since worked on a variety of projects including providing technical support to LLW Repository Ltd.’s Environmental Safety Case (ESC) and inventory teams; helping to develop the NDA Value Framework and undertaking various human intrusion and other environmental radiological assessments to facilitate radioactive waste disposal across a number of UK nuclear sites.  Tim has also contributed to numerous BAT assessments, completed work on site delicensing and investigated approaches to knowledge management to prevent intrusion into residual contamination after release from RSR.
