Overview

The Standard provides the functional requirements for the alarm systems in the main control room of nuclear power plants. It gives definitions of the terms used for alarm functions. It also establishes the human factors requirements and the design guidelines for alarm presentation for the main control room of nuclear power plants. It specifies the alarm functions including those for the selection and definition of original alarm signals, alarm signal processing (for example, event sequence processing, static and dynamic prioritization), alarm display processing (for example, alarm suppression) and the use of associated display devices (for example, Visual Display Unit (VDU), conventional alarm fascia, mural display), with acknowledge and reset sequences, and other related matters. The standard is designed to help reduce problems that are by no means nuclear-specific: omission of important alarms, delay in detecting important alarms, increased workload that may affect the performance of other operational activities, inattention to frequently activated alarms (known as "nuisance alarms"), and confusion associated with the misunderstanding of the relationships among alarms and of the importance of alarms. Therefore it can also be used as a useful basis for the maintenance of other installations. The responsible committee is DKE/UK 967.1 "Leittechnik für kerntechnische Anlagen" ("Instrumentation and control of nuclear facilities") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
