Abstract
The characteristics of sodium permeation through graphite and the accompanying swelling of the graphite are examined for the central rotating column of a BN-600 reactor.
The sodium transport parameters when sodium comes into contact with graphite at 350–500°C for up to 400 h are determined experimentally. Under these conditions, the permeation parameter is (0.13–1.3)·10−11 m2/sec, which corresponds to an effective diffusion coefficient (0.2–2)·10−11 m2/sec. The ratio of the increment to the graphite volume and the sodium mass there is ∼0.85.
