This position offers you the opportunity to deepen your expertise in radioactive waste management by conducting cutting-edge research on the use of concrete and cement for waste containment. You will work with trace amounts of radioactive tracers in an inert gas glove-box and learn to interpret results into parameters used for safety evaluations of waste repositories. The experience gained will be highly valuable for a career in nuclear waste management-a highly sought-after qualification in today's nuclear energy sector.
Project overview
The position is based in the Nuclear Chemistry research group, focusing on radioactive waste management.
Intermediate-level radioactive waste (ILW) is often conditioned with concrete and/or placed in steel containers. It can also include steel from decommissioned nuclear reactors. In this project, you will investigate the sorption behavior of radionuclide tracers on a mixed medium of cement and iron.
Key research questions include:
•
How does iron influence the redox states of redox-sensitive radionuclides?
•
Does the dissolution of Fe(II) affect the sorption of other divalent metals?
Your main tasks will include:
•
Conducting experimental studies on radionuclide sorption onto cement phases
•
Performing spectroscopic studies with XPS to determine metal oxidation states
•
Participating in DFT calculations on metal sorption onto tobermorite
The work will be carried out in an inert gas glove-box, and the oxidation state of metals will be studied using advanced analytical methods.
About the division
The Energy and Materials division at the Department of Chemistry and Chemical Engineering conducts diverse research addressing critical material and energy challenges. Our mission is to contribute to a sustainable future by improving material and energy systems across multiple applications, including:
• High-temperature corrosion prevention
• Development of advanced fuel cells
• Recycling of valuable materials
• Innovations in nuclear energy
Our collaborative and dynamic environment offers ample opportunities for personal and professional growth.
Qualifications
To qualify for this position, you must meet the following criteria:
• Hold a doctoral degree in Chemistry or Chemical Engineering, awarded no more than three years before the application deadline.
• Have at least two peer-reviewed research publications.
• Possess strong verbal and written communication skills in English.
Contract terms
This is a full-time postdoctoral position with a fixed term of two years. Supervision and support will be provided for both experimental and modeling studies.
Please observe: Since the department is also a nuclear facility, only citizens of the countries who are signatory of Treaty on the Non-Proliferation of Nuclear Weapons can apply and be considered for the position. Please check the status of your country before applying.
The position requires physical presence throughout the entire employment. A valid residence permit must be presented by the start date, otherwise the offer may be withdrawn.
