AbstractAbstract
[en] The Hertzian indentation technique has been used to determine the fracture toughness, KIc of two borosilicate glasses developed to contain high-level nuclear waste. For the product VG 98/12, adding selected groups of fission products leaves KIc unchanged, but addition of Pb lowers KIc by approx. 20%. Radiation with 77 MeV α-particles to a dose of approx. 1015 α/cm2 increases KIc by approx. 75%. For the product SM 58 LW 11, the fracture toughness was measured on pieces taken from different parts of a large cylinder to investigate the effects of segregation phenomena and of partial crystallization and formation of small cristobalite inclusions which decrease KIc by approx. 25%
