Neutron imaging of industrial two-phase flows, being a promising technique, has gained increasing attention in the last two decades. We focus on annular flows in nuclear fuel bundles. For annular flows, occurring typically at the upper part of the fuel bundles of boiling water reactors (BWRs), the potential dryout of the coolant liquid film constitutes a safety concern and is a limiting factor...

The hydrogen uptake during steam oxidation of the nuclear fuel cladding made from zirconium alloys is very important for the development of nuclear accidents. It changes the time scale of hydrogen release and degrades the mechanical properties of the fuel cladding. The hydrogen uptake results in an embrittlement of the zirconium alloy connected with a strong reduction of the thermo-shock...

In recent years several new techniques have enlarged the area of applications of neutron imaging; among the most important of these are Bragg-edge mapping, polarised neutron imaging and interferometric imaging. In this talk an overview will be given on recent developments in these methods at CONRAD, the neutron imaging instrument at the Helmholtz Centre Berlin. Polycrystalline materials...
