Chalmers University of Technology, Gothenburg, Sweden

Nuclear Chemistry at Chalmers University of Technology is one of very few universities in the world that has fully equipped laboratories for work with gram amounts of alpha emitting nuclides as well as gamma sources – the alpha, fuel and gamma labs. Adjoining the alpha lab is the new nuclear fuel laboratory allowing production of nuclear fuel pellets containing U, Pu and Am using the sol gel as well as a dry route. Work in this lab is limited to 100 g Pu and 10 g of Am. All work with alpha emitters in the two labs is performed in glove boxes. The gamma laboratory is equipped with a hot cell that allows work with up to 370 GBq of Co-60. This hot cell can be used e.g. for work with aged, used nuclear fuel.

The analysis equipment includes HPGe, PIPS and LSC detectors for radiation measurements as well as centrifuges (AKUFVE) and mixer-settler systems for fast and accurate solvent extraction studies. The extraction equipment is available in plastic as well as metal versions to make studies of all types of extraction systems possible. There are also XRD, SEM, ICP-MS and ICP-OES that, unlike at most other laboratories, can be used for radioactive samples. A strong Co-60 irradiation source (11 kGy/h) for large volume samples is available as well as some weaker Cs-137 irradiation sources.

Collaboration with Maxlab in Lund, Sweden, makes it possible to perform EXAFS studies on solid and liquid radioactive sources, including actinides.

Thus it is possible to perform most types of thermodynamical investigations as well as small-scale solvent extraction process tests. It is also possible to study radiolysis in a wide range of dose rates. Studies of alpha radiolysis with At-211 are also possible; this nuclide is short-lived and leaves a solution that can be treated as non-radioactive. Fabrication and investigation of novel nuclear fuels is possible as well as fabrication of dedicated fuels for e.g. fuel dissolution studies.

Gamma ans Alpha labs

Access requirements

The persons working in these labs must pass security clearance which depends on the purpose of the work and the tools to be used.

Security clearance
Personal documents needed to start the process getting access to the controlled area (4 weeks process time):
1.    CV
2.    Copy of passport
3.    Proof of valid security clearance for work in controlled area, issued in EU-member state

Dosimetry
If the person has a dosimeter, a dosage certificate is needed as well as an innocuousness certificate from your medical department (not older than 5a).

Medical check
A medical checkup is required prior to starting work and is done upon arrival to the PF.
Duration = 0.5 day

Radiation protection and safety course
After arrival, a radiation protection exam must be passed before starting active work.

Additional site specific training
None
