Abstract
The structural integrity of the reactor pressure vessel (RPV) of light water reactors (LWR) is of utmost importance regarding the safety of operation and service lifetime. The fracture behaviour of low-alloy RPV steels with different microstructures (base metal, simulated weld coarse grain heat-affected zone) in simulated LWR environments was evaluated by elastic plastic fracture mechanics (EPFM) tests with different strain rates and by metallo- and fractographic post-test evaluations. These tests revealed some evidence of possible high-temperature water effects on the fracture behaviour and potential synergy with environmentally-assisted cracking and dynamic strain aging.
