Cobalt content and vacancy swelling of ChS-68 steel

Analysis of the state of fuel-element claddings before and after operation in a fast reactor revealed a statistically significant factor correlating with the vacancy swelling of 06Kh16N15M2G2TFR (ChS-68) austenitic steel. This factor, which depends on the quantitative composition of the alloying and...

Description
Summary:Analysis of the state of fuel-element claddings before and after operation in a fast reactor revealed a statistically significant factor correlating with the vacancy swelling of 06Kh16N15M2G2TFR (ChS-68) austenitic steel. This factor, which depends on the quantitative composition of the alloying and impurity elements in steel melts, explains the reason for the large (more than a factor of 2) differences in the size changes of spent fuel elements in BN-600 reactor fuel assemblies and makes it possible to predict the swelling resistance of different batches of casing tubes made of ChS-68 steel.[PUBLICATION ABSTRACT]
