The results of materials-technology investigations of a spent fuel assembly
from a reactor at the Obninsk nuclear power plant, the first nuclear power
plant in the world, before the rated burnup and after prolonged dry storag
e (for about 40 years) were presented.
It was established that the fuel elements from the fuel assembly studied ar
e in satisfactory condition. No appreciable damage due to the prolonged sto
rage was found: the outer diameter remains within the technological toleran
ce limits and the strength and the plasticity of the jackets are high. Only
surface corrosion damage to 10 mu m depth was found on the fuel-element ja
ckets. The fuel composition remained whole. 6 figures, 1 table, 3 reference
