Abstract

Tests of simulators of fuel elements are carried out (coaxially located tubes from steel 16Cr12WMoSiVNbB up to 1100 mm long with a gap of 150 microns, filled with an Pb-Mg eutectic) at temperature drop 923-693 K lasting up to 750 hours. On the basis of gravimetric and laser atomic spectrometer analyses it isn't revealed corrosion interaction of an alloy with steel.
