“…Molten lead-bismuth eutectic alloy (LBE) has been used successfully as a target in a particle accelerator, for the production of spallation neutrons [1]. A main advantage of using liquid LBE is that it can be pumped out of the target area to a heat exchanger, cooled there, and then pumped back into the target area.…”

“…Furthermore, it can be observed that the Hg in the middle capsule leaked out and filled the gaps in the rod. In another rod ( Figure 16 ) of the same irradiation experiment, many samples were irradiated in contact with Pb-Bi eutectic, the target material of MEGAPIE [ 13 ]. In this rod, a big capsule of the martensitic steel T91 contained many tensile specimens and TEM discs (used for transmission electron microscopy measurements).…”

NEURAP—A Dedicated Neutron-Imaging Facility for Highly Radioactive Samples

et al. 2021

NEURAP is a dedicated set-up at the Swiss neutron spallation source (SINQ) at the Paul Scherrer Institut (PSI), optionally implemented as a special configuration of the neutron-imaging station NEUTRA. It is one of very few instrumentations available worldwide enabling neutron-imaging of highly radioactive samples to be performed routinely, with special precautions and following a specific procedure. Since the relevant objects are strong γ-sources, dedicated techniques are needed to handle the samples and to perform neutron-imaging despite the radiation background. Dysprosium (Dy)-loaded imaging plates, effectively made sensitive to neutrons only, are employed. Neutrons are captured by Dy during neutron irradiation. Then the imaging plate is erased removing gamma detections. A subsequent relatively long self-exposure by the radiation from the intrinsic neutron-activated Dy within the imaging plate yields the neutron-only radiograph that is finally read out. During more than 20 years of NEURAP operation, images have been obtained for two major applications: (a) highly radioactive SINQ target components were investigated after long-term operation life; and (b) spent fuel rods and their cladding from Swiss nuclear power plants were characterized. Quantitative analysis of the image data demonstrated the accumulation of spallation products in the lead filled “Cannelloni” Zircaloy tubes of the SINQ target and the aggregation of hydrogen at specific sites in used fuel pins of power plants and their cladding, respectively. These results continue to help understanding material degradation and optimizing the operational regimes, which might lead to extending the safe lifetimes of these components.

“…The leading candidate material for the fuel module housing and spallation target housing is T91 alloy, a ferritic/martensitic steel that has demonstrated good ductility retention to high dose in fast reactor environments. T91 alloy was used as the Pb-Bi container material in the recently completed MEGAPIE experiment [5]. In this application, the T91 alloy received a proton dose of up to 1.1 Â 10 25 protons/m 2 .…”
