Position available: research scientist in hydrogeochemistry

Main tasks

The work will be connected to nuclear decommissioning and disposal of nuclear waste in deep repositories and will be based on competence related to geochemical processes, interactions and modelling.

The tasks will include:

  • Numerical simulations of transport of radionuclides and metals, including geochemical/hydrochemical reactions and kinetics, utilizing numerical models, including programming, if feasible.
  • Laboratory experiments to provide relevant chemical speciation data in order to understand processes such as dissolution/precipitation kinetics, redox, sorption and remobilization dynamics at relevant time scales as well as colloid transport for modeling purposes.
  • Production of model parametrization data, utilizing advanced technologies in collaboration with CERAD personnel.
  • Field experiments to study flow and transport in the subsurface using lysimeters, and geophysical techniques for characterization and time-lapse measurements. Combined in situ size and charge fractionation techniques will also be applied.

The research will be carried out within CERAD, in close collaboration with hydrogeologists at the MINA faculty, at other national institutions and internationally.  The MINA group is currently applying MODFLOW, SUTRA and Hydrus to simulate flow and transport under saturated and unsaturated conditions during different temperature regimes as well as degrees of heterogeneity.

Results are expected to be published in peer reviewed literature as well as being presented at national and international conferences.

Required academic qualifications

Applicants must have a PhD degree or equivalent qualifications in hydrochemistry, geochemistry, hydrogeochemistry, environmental chemistry, radioecology or nuclear chemistry.

Experience from work with ionizing radiation or radionuclides as well as metals/mineralogy is an advantage. For candidates without competence within radiation, the Radiation protection course (KJM350) offered at NMBU will be mandatory.

Knowledge of chemical speciation concepts as well as experience with relevant models such as PhreeqC, or related extensions such as HP2 (Hydrus) or piChem (FeFlow) or similar programs would be an advantage.

Required personal skills

  • Enthusiasm and creativity in research and education
  • Ability to work individually and in teams
  • Ability to work in a result-oriented environment
  • Flexibility with respect to work tasks
  • Ability to create a positive working environment
  • Good capabilities in English, both orally and in writing
