The specific activities to be performed in this task are: (1) continuation of Phase 2 of the Fifth Irradiation Series and (2) completion of the Si Irradiation Series, including testing nine irradiated Italian crack- arrest specimens.

It should be noticed, that the Duplex specimens used in the HSSI program were first produced, and afterwards irradiated in the Oak Ridge Research ://. 1. Introduction. The Heavy-Section Steel Technology Program at Oak Ridge National Laboratory (ORNL) has produced new statistical representations for the two properties, the plane-strain static initiation toughness K Ic and the plane-strain crack-arrest toughness K Ia, used to characterize the fracture toughness of reactor pressure vessel (RPV) steels.
