Dr. Roger D. Wilmot, BA, PhD Principal Consultant
Dr. Roger D. Wilmot has degrees in Earth Sciences from Cambridge University (BA) and Imperial
College, London (PhD). He is a geologist with over 20 years experience in providing a broad range of
research, consultancy and management services to a range of clients, starting with site
characterisation work for the four proposed UK shallow sites in the 1980s.
Dr. Wilmot is chair of SSM’s OVERSITE international panel responsible for regulatory review of SKB’s
risk assessments for radioactive waste disposal in Sweden. He has also worked fro the Swedish
regulators on Quality Assurance, development of a strategy for consideration of future human actions
in assessments and the conduct of risk assessments.
Dr Wilmot provided technical support to the Environment Agency and SEPA in the recent revision of
the agencies’ Guidance on Requirements for Authorisation, and was part of the management team for
the review on behalf of the Environment Agency of BNFL’s safety case for the LLWR.
Dr. Wilmot developed a computer code for UKAEA to undertake radiological performance assessments
of waste disposal and storage facilities, and assessments of the impact of radioactivity in the
environment. He has led a variety of waste management options appraisals for UKAEA Dounreay,
including an evaluation of the transport of radioactive waste, as part of BPEO studies. He authored a
draft ESC for the Pits facility at Dounreay.
Dr. Wilmot was responsible for development, implementation and trial application of an methodology
for assessing the doses associated with landfill sites for Special Precautions Burial of LLW, and has
extended and used this methodology for PA of on-site disposal of radioactive wastes and for assessing
the dose implications of dustbin disposal of VLLW.
Dr. Dev Reedha, BEng(Hons), PhD Senior Consultant
Dr. Dev Reedha has degrees in Mechanical Engineering and Energy Systems (BEng First Class
Honours) and Engineering (PhD) from the University of Manchester. He has six years experience in
radioactive waste management and nuclear consultancy and research, and ten years experience in
computational fluid dynamics, mathematical modelling and simulation of fluid flow in sedimentary units,
and in computer code development. He also has experience in software consultancy.
Dr. Reedha has carried out key technical work in radioactive waste management. On behalf of the UK
environmental regulators (through SNIFFER), he developed a computational model to evaluate
allowable disposals of radioactive waste to landfill, and provided technical support for the evaluation of
doses associated with VLLW disposals. On behalf of Defra, he provided technical support on a project
to advise Government on the feasibility of gathering data on the geographical generation of nonnuclear
LLW, including VLLW, within the UK. For ONDRAF-NIRAS, he has reviewed the treatment of
concrete degradation in safety assessments, and is currently working (lead author) on the Belgian
Category A inventory report.
Dr. Reedha is an experienced groundwater flow and contaminant transport modeller using state-of-theart
software packages such as FEFLOW and GoldSim-RT. He contributed to an assessment of postclosure
safety of the LLW disposal facility near Drigg, on behalf of the Environment Agency. For
DSRL, he worked on the development of a risk assessment model in GoldSim-RT for solid LLW
disposal at Dounreay, and is currently undertaking hydrogeological modelling analysis of the proposed
LLW facilities using FEFLOW. On behalf of the Nuclear Decommissioning Authority’s Radioactive
Waste Management Directorate (NDA RWMD), he recently undertook transient three-dimensional
groundwater flow calculations using FEFLOW to evaluate potential hydrological interactions in a
geological disposal facility during the operational phase and after facility closure.
