Nuclear Safety Research

The Institute carries out application oriented Research in the field of radioecology. The investigations help to protect people and environment from the hazards caused by potential transfers of radioactive heavy metals into the biosphere.

Our goal is to reveal the interactions and mobility of Actinides (Thorium, Uranium, Neptunium, Plutonium, Curium and Americium) and further long-lived radionuclides on a molecular level in geo- and biosystems, which contributes to the macroscopic process understanding and allows to model the respective processes.

Typical application cases are the development and assessment of restoration methods in uranium mining, the long-term safety evaluation of nuclear repositories, and the knowledge about the behaviour of accidental nuclear contaminations in the environment.

Research topics:

 

Actinides (Metals) in biosystems

 

Actinides (Metals) in nuclear waste disposal systems
 

 

Bakterien

[Process understanding and mobility of actinides with biomolecular interfaces and in biosystems]

  

 

Muskovit

[Structure, kinetics, thermodynamics and modelling of sorption of actinides on rocks, in soils, onto colloids and in biofilms]

Methods:

All experimental works can be carried out in radiochemical laboratories within controlled areas, the institute provides a variety of analytical tools:

  • X-ray absorption spectroscopy (EXAFS, XANES)
  • Laser-induced spectroscopies (TRLFS, LIPAS)
  • Vibrational spectroscopies (ATR-FT IR, PTBD)
  • Colloid chemistry methods (LIBD, PCS)
  • Microbiological methods
  • Element and component analyses (ICP-MS, AAS, AES, IC; HPLC)
  • Surface determinations (BET)
  • Digestion methods

A brief review of the History of the institute may also be of interest.
