Master curve evaluation of ANP-5 steel using mini-CT specimens

The nuclear industry demands analyses that make possible the long-term operation of power plants (i.e., beyond 40 years). In this sense, one main challenges to overcome is restricted amount material available extend surveillance programs. To mitigate issue, mini-CT specimens have been proposed for evaluation fracture properties reactor pressure vessel (RPV) materials, and particularly, corresponding Master Curve. These can be taken from broken halves previously tested Charpy specimens. work, employed evaluate reference temperature RPV ANP-5 steel in non-irradiated conditions. results were compared with those obtained by means conventional tests.
