The Principal Working Group 5 of the Committee on Safety of Nuclear Installations of the Nuclear Energy Agency (NEA)/Organization for Economic Cooperation and Development (OECD) initiated a survey on the use of quantitative safety guidelines in the member countries. In the development of the questionnaire, it was recognized that the quantitative criteria and guidelines used in conjunction with the regulation, design, licensing, and operation of nuclear power plants fall into two distinct categories: one aiming for a high level of safety in the operation of NPPs, and the other providing a set of safety standards against which their risk should be assessed. Only the second category was judged to be relevant. Most OECD countries responded and provided the requested information. Probabilistic safety assessment (PSA) is the instrument to demonstrate compliance with probabilistic safety criteria (PSC) or to indicate the level of conformance with probabilistic guidelines. The 13 countries included in the survey are representative of the state of the art of PSA and PSC. This article is a review of the survey results.
