1.1 General
This Standard provides requirements and guidance related to the performance of periodic safety reviews (PSRs) for nuclear power plants (NPPs).
Note: This Standard may be used to provide guidance for nuclear facilities other than NPPs using a graded approach.
1.2 Requirements and guidance
This Standard provides requirements and guidance related to the PSR for:
developing the basis document;
conducting reviews of modern requirements documents and practices;
conducting safety factor reviews to identify findings;
performing analyses of safety factor findings, including consolidation of identified gaps and strengths, development of global issues, and preparation of a global assessment report (GAR); and
preparing the integrated implementation plan (IIP) where the developed global issues are resolved into actions.
1.3 Deliverables
This Standard identifies required deliverables that will help facilitate achieving the objectives of the PSR process.
1.4 Terminology
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
1.5 Additional terminology
In this Standard, “shall be considered” or “shall consider” means that the user evaluates the impact and documents any decisions.
Note: Decisions could include no action.
