PhD student position in Material and Safety challenges in lead and lead/bismuth cooled Gen IV Reactors

Information about the research/the project/the division
Chalmers University of Technology's Department of Chemistry has about 300 employees which are working within four research divisions and one administrative unit.

The division of Energy and Materials hosts the research group of Nuclear Chemistry / Industrial Materials Recycling comprising 8 senior scientists as well as 11 PhD students and postdocs, headed by two professors in Nuclear Chemistry and Industrial Materials Recycling. The research group is highly international and has a wide international network.

Besides the research on material interactions in reactors at elevated temperatures, the group is specialized in aqueous chemistry and solvent extraction used for both recycling of materials and nuclear applications.

In the field of nuclear chemistry, there are four major research areas: 1) novel nuclear fuels for the generation IV nuclear power systems, 2) radionuclide release from severe nuclear accidents, 3) partitioning and transmutation of spent fuel, and 4) final repository of radioactive waste. The nuclear chemistry research facilities are unique for an university in Europe, with a dedicated alpha laboratory for nuclear fuel research and a gamma lab with "hot cell" and irradiation source. In addition, there are several radiochemistry laboratories for trace-level work.

Major responsibilities
The succesful candidate will take several important steps to increase the understanding of and opportunities to investigate the reactor safety from a chemical point of view for Lead and Lead/Bismuth-Cooled Gen IV Reactors. The physical barriers set up for a safely functioning nuclear reactor are (generally): the fuel matrix, the cladding, and the coolant (Lead-Bismuth eutectic (LBE), Pb, other), reactor vessel, primary containment and the secondary containment. This specific project aims to test the capability of the 3rd physical barrier's (the coolant, here LBE and Pb) capability of retaining, converting and containing potential fission products (both volatile: iodine, Cs and Rb and non-volatile e.g. U, Te, Ru, Mo) released from e.g. a damaged fuel pin before leaving the reactor vessel. The hypotheses to be studied are that the majority of the resulting fission products will be retained and immobilized in the LBE or PB, forming either chemical very stable species through or their release into a gas phase (e.g. air) is very slow.

The candidate's work will be mainly experimental. Results will however be evaluated and brought into context by the project partners from theoretical and computational chemistry. The use of radioactive tracers, work in a controlled environment as well as access to corrosion labs and microscopy infrastructure is foreseen.

Position summary
Full-time temporary employment. This position is limited to a maximum of four and half years.

For you to qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in in Chemistry, Matallurgy and Materials Science. We believe that you as a candidate has expertise in experimental work in Chemistry or Materials Science. We also think you are able to work independently and take responsibility for progress and quality of the project.

The position requires sound verbal and written communication skills in English. Swedish is not a requirement but if you have an interest in learning Swedish, Chalmers offers Swedish courses.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
