• The present work was undertaken to obtain the effect of thermophoretic adherence of nuclear aerosol on the reactor containments in the event of a hypothetical accident of LMFBR. In the accident, sodium oxide aerosol containing PuO<SUB>2</SUB>-UO<SUB>2</SUB> fuel and fission products may be suspended in the containment and tends to deposit on the cold wall of the containment, so that the aerosol concentration decreases by thermophoresis in addition of settling and diffusional plating. Experiments were made to determine the degree of thermophoretic adherence for sodium oxide aerosol in a chamber during sodium burning. The results obtained by the experiments were compared with those of the calculations and the agreement was satisfactory.
