    Abstract

    The present Light Water Reactor (LWR) pressure vessel safety regulations refer to the actual steel fracture toughness through indexation to Charpy impact test ductile-to-brittle transition temperatures or upper shelf energies, depending on the fracture mode. These conventional concepts bear upon an absolute one: reactor service life limit and total generated MW(e) power. They do not nor do need to carry an absolute meaning, intrinsically, provided they adequately correlate with fracture probabilities.
