Abstract
The Rossendorf Beamline at the European Synchrotron Radiation Facility is equipped with a unique radiochemistry experimental station. This dedicated station has been designed to perform environmentally relevant experiments on radionuclides, in particular actinides, using synchrotron based X-ray absorption fine structure spectroscopy. The technical concepts and the layout of this experimental station, where radioactive solids and liquids with activities of up to 185 MBq can be studied, are presented. The radiological safety of experimenters, equipment, and of the environment are ensured by the specially developed radiochemistry safety system. The multibarrier concept, the ventilation and air monitoring systems, the radiological protection system, and special software components for recording and visualisation of the safety status are described in detail.
Abstract
Die Rossendorf-Strahllinie an der Europäischen Synchrotronstrahleinrichtung (ESRF) in Grenoble umfasst eine unikale radiochemische Experimentieranlage. Dieser spezialisierte Messplatz wurde konzipiert, um umweltrelevante Röntgenabsorptions-Feinstruktur Experimente mit Radionukliden, speziell Aktiniden, am Synchrotronstrahl durchzufähren. Das gesamte technische Konzept des Messplatzes, an dem radioaktive feste und flüssige Proben mit Aktivitäten bis zu 185 MBq untersucht werden können, wird vorgestellt. Der Schutz der Experimentatoren, der sonstigen Ausrüstung sowie der Umwelt vor radioaktiver Strahlung wird mittels eines speziell entwickelten radioaktiven Sicherheitssystems gewährleistet. Das mehrstufige Barrieren-Konzept, das Ventilations- und Luftüberwachungssystem, sonstige Strahlenschutzeinrichtungen sowie spezielle Softwarelösungen zur Registrierung und Visualisierung des Zustandes der Sicherheitskomponenten werden detailliert beschrieben.
