Abstract
Positron Annihilation Spectroscopy is a valuable microscopic method to study radiation damage in nuclear reactor pressure vessel steels. At SCK . CEN, a new positron lifetime setup, suited to measure positron l ifetimes in irradiated steel, is being constructed. The particularity of this setup is that the prompt count rate originating from the induc ed Co-60-activity in the steel is highly reduced. Some preliminary res ults obtained for unirradiated SA-508 steel are discussed.
