The operational laboratory
The Chemists have access to a number of analytical techniques:
- AAS, Atomic Absorption Spectroscopy, Perkin Elmer 1100
- FTIR, Fourier Transform Infrared Spectroscopy, Perkin Elmer Paragon 1000
- TOC and TIC, Total Organic Carbon and Total Inorganic Carbon, O-I-analytical 1010
- UV/ VIS Spectrometry, Ultra Violet/ Visual Spectrometry, Perkin Elmer Lamda 2
- Gamma-Spectroscopy, Canberra S404
- Dissolved gases, Orbisphere MOCA O2 /MOCA H2
The main objectives of the laboratory are to control and monitor parameters of the water coolant in the reactor systems and experimental loops. The measured aqueous parameters are for example conductivity, pH, dissolved gases and the content of silica and humus. The transports of radioactive species in the coolant are measured by gamma-spectroscopy on grab samples, fi lters (cation and anion exchange filters and particle filters) and coupons. Different reactor systems are simulated in the experimental loops by use of their respective chemistry.
The laboratory is also responsible for the purifi cation systems in the reactor and experimental systems. The operational laboratory has more than 40 years of experience in controlling and monitoring aqueous systems.
The analytical laboratory
The main analytical techniques used in the analytical laboratory are:
- Ion chromatography, 2 x Dionex and 1 x Iontrac 203 General Electric
- Capillary Electrophoresis, Waters Capillary Ion Analyzer
- X-ray Fluorescence Spectrometer, Spectro 2000
- Gas Chromatography, HP 6890
The main objective of the analytical laboratory is to characterize the content of dissolved species, particles and gases in the environment of the different coolant systems, aqueous as well as gaseous. The sampling techniques are grab samples and integrated methods such as fi lters (cation and anion exchange filters and particle filters). The laboratory has over 10 years experience in the field of measuring low levels (ppb and sub ppb) of contaminates in aqueous environment.
