“…It should be noted that the results of EDX analysis agree with the results of chemical analysis of the LGE and LBE samples from the same test, which showed the Cr, Ni and Mn content in LGE was much high than that in LBE [7]. Fig.…”

“…This was considered as time zero of the experiment. A silver tube of 2 cm length (Goodfellow, thickness 0.020 ± 0.003 mm, purity 99.9 %) was lining the inside of the end of each column (8), where the temperature was approximately 298 K, to trap polonium species not retained on the SS316L surface. The activity of 206 Po was measured by a HPGe-γdetector in comparison with measurements, in the same geometry, of certified standard reference sources.…”

“…Several methods have been considered for removing polonium directly from the LBE, see e. g. Refs. [5,7,8], or to permanently absorb it from the gas plenum above the LBE using dedicated filter materials. For the latter purpose, the first two papers of this series studied the interaction of polonium with different noble metals as candidates for filtering materials [9,10].…”

“…The major concern is the formation of 210 Po, which has an inhalation and ingestion radiotoxicity among the highest of all the known radionuclides [4,5]. In a typical neutron environment characteristic of fast reactors (neutron fluxes at the level of 10 15 n/(cm 2 s)) its activity can reach up to 10 11 Bq/kg [6]. In the MYRRHA reactor pool, assuming that all 210 Po is retained in LBE, the estimated production of this radioisotope after one irradiation cycle at nominal power would be at the level of 350 g, or 5.5 Â 10 4 TBq [7].…”
