The Conversion of Research Reactors to Low-Enriched Fuel and the Case of the FRM-II
The use of highly enriched uranium (HEU) as fuel in research reactors runs contrary to the concept of proliferation-resistant nuclear technologies. Consequently, for more than two decades, international activities have been undertaken to terminate the use of HEU in research reactors by supporting the conversion of these facilities to low-enriched uranium (LEU). Achievements, setbacks and perspe...
متن کاملAdvanced Neutron Instrumentation at FRM-II
The construction of the new German high flux neutron source FRM-II is finished and FRM-II is waiting for its licence to start nuclear operation. With the beginning of the routine operation 22 instruments will be in action, including 5 irradiation facilities and 17 beam tube instruments, most of them use neutron scattering techniques. Additional instruments are under construction. Some of these ...
متن کاملThe New German Neutron Source Frm Ii
The new research reactor of the Technische Universität München will provide the German needs of neutrons for the beginning of the next century. High intensities of thermal neutrons are provided by a particular densely packed core of highly enriched uranium and are extracted by 12 beam apertures. The low thermal power of 20 MW allows the positioning of a D2 cold source at a maximum of the therma...
متن کاملInstrument Control with TACO at the FRM-II
With the start up of the new German Neutron Source FRM-II in Garching, a common instrument control system has to be installed at the different neutron scattering instruments. With respect to the large variety of instruments, a modular system was required. In spite of starting from scratch, a well developed and tested system was needed, in order to meet the restricted man power and short time sc...
متن کاملSPHERES, Jülich's high-flux neutron backscattering spectrometer at FRM II.
SPHERES is a third-generation neutron backscattering spectrometer, located at the 20 MW German neutron source FRM II and operated by the Jülich Centre for Neutron Science. It offers an energy resolution (fwhm) better than 0.65 μeV, a dynamic range of ± 31 μeV, and a signal-to-noise ratio of up to 1750:1.
