The role can be based at Harwell, London, Birchwood or other locations will be considered. The successful applicant will be part of a multi-disciplinary team (including chemists, physicists, geologists, engineers, safety case specialists and mathematicians) who provide consultancy, modelling, safety case and laboratory studies to underpin the science, technology and engineering to allow the safe disposal of radioactive waste.

The successful candidate will provide technical leadership across a portfolio of projects within the area of Radioactive Waste Management, centred on geochemistry and geochemical modelling for geological disposal. You will manage and support both large and small consultancy projects and proposals, many of which are multi-disciplinary. You will have the opportunity to lead and support client relationships and projects, prepare proposals, liaise with clients, manage projects and subcontractors, provide advice and deliver technical reports in line with client and regulatory requirements.

You will support senior managers and provide technical leadership on a range of consultancy projects for customers , including radioactive waste management organisations, radioactive waste producers and regulators, both in the UK and overseas. Your work will focus on the geochemistry and geochemical modelling associated with the disposal of radioactive wastes, including their chemical interactions with groundwater, backfills, encapsulants and other components.

The responsibilities include

• Developing conceptual models for the representation of chemical processes in performance assessment models that support safety cases
• Developing models to aid the understanding of waste reactions with engineered materials, groundwaters and geological materials
• Providing geochemical and chemical input to a range of modelling studies led by the wider modelling team
• Working with experimentalists to aid the design of programmes and to analyse and interpret results from studies on contaminant chemistry and transport
• Delivering high-quality and bespoke technical and strategic support to our clients

• Experience in one of the following areas
  o The development of chemical models for the prediction of interactions of contaminants with groundwater, engineered barriers and geological materials
  o Understanding of the chemical behaviour of radioelements and non-radiological contaminants under disposal conditions
  o Working with PHREEQC or similar tools for geochemical modelling
  o A track record of problem solving in the field of geochemistry
  o Analysis of large geochemical datasets
  o Performing laboratory experiments studying sorption, solubility and diffusion of contaminants, under conditions relevant to safety assessment for waste disposal facilities
  o Working on problems relevant to the management and disposal of radioactive waste
• Experience of leadership or people management
• Demonstrable ability to write clearly and present complex arguments in a well-structured manner
• Adaptable and able to work on a variety of projects, prioritising as appropriate.
