Abstract

A simulated nuclear waste glass was self-irradiated by doping with short-lived actinides of ²³⁸Pu and ²⁴⁴Cm. Changes in the hardness, the Young's modulus and the fracture toughness, as a function of irradiation dose, were measured by use of indentation techniques. The irradiated glass was annealed at temperatures from 573K to 723K for periods of upto 48 hours, and the recovery of these changes were measured as a function of annealing temperature and time. The results of the annealing show that the hardness and the Young's modulus were almost recovered to the original values at temperatures above 673K within 10 hours, while the recovery of the fracture toughness was minimal in the region of temperature and time.
