The large-scale experiments CometPC-H4 and -H5 investigate cooling of simulated corium melts by flooding the melt from the bottom through layers of porous, water filled concrete. Both experiments use 800 kg of oxidic and metallic melts, initial temperature from 1800 to 1900 C, with simulation of nuclear decay heat by inductive heating with 300 KW t...
Neutron spectra were measured at the GSI heavy ion accelerator using the Bonner sphere spectrometer NEMUS. The irradiation experiments were carried out at Cave A, an experimental area at the GSI heavy ion synchrotron SIS. A 400 MeV/u carbon ion beam impinging on a thick graphite target was used as neutron source. Spectral distributions were determi...
As one of the major tasks of the ECOSTAR project, two large-scale experiments on oxidic melt spreading were performed. The experimental conditions were selected to represent low flow rate of oxidic melt, released with low overheat, so that stop of the spreading process may occur during ongoing melt release, and spreading would be incomplete. Beside...
