... that does not impose the same stringent sealing requirements on samples. The results are used to examine the size dependence of samples, virgin material variation, and the evolution of permeability with radiolytic oxidation. graphite permeability gas transport properties irradiated material...

... Crystal defects induced by irradiation obstruct dislocation movement. Hence, the critical resolved shear stress of irradiated material increases. While part of the radiation defects are swept by dislocations released from dislocation sources; therefore localization of plastic deformation...

... laboratories within Europe. The paper reviews the general information from RESQUE and summarizes the conclusions. Specific details are given in other contributions to this Symposium. KEYWORDS: reactor pressure vessel steel, reconstitution, irradiated material, stud welding, electron beam welding, Charpy-V test...

... surveillance programs. The final application of this new method is to predict fracture toughness of irradiated materials to determine pressure-temperature curves for nuclear power plant operation and RT PTS values in compliance with the current regulatory rules for the nuclear-utility industry. In this paper...
