IEC 61031/FRAGF ED2

Nuclear facilities - Instrumentation and control systems - Design, location and application criteria for installed area gamma radiation dose rate monitoring equipment for use during normal operation and anticipated operational occurrences IEC 61031/FRAGF ED2

Scope

IEC 61031:2020 applies to the design, location and application of installed equipment for monitoring local gamma radiation dose rates within nuclear facilities during normal operation and anticipated operational occurrences. High range area gamma radiation dose rate monitoring equipment for accident conditions currently addressed by IEC 60951-1 and IEC 60951-3 is not within the scope of this document. This document provides guidelines for the design principles, the location, the application, the calibration, the operation, and the testing of installed equipment for continuously monitoring local gamma radiation dose rates in nuclear facilities under normal operation conditions and anticipated operational occurrences. These instruments are normally referred to as area radiation monitors. Portable instruments are also used for this purpose but are not covered by this document.

This document is to be used in conjunction with IEC 60532:2010. This second edition cancels and replaces the first edition published in 1990. This edition includes the following significant technical changes with respect to the previous edition:
a. The scope of the standard is extended from nuclear power plants to nuclear facilities and the title is accordingly aligned.
b. The relevant standards published by IEC SC 45A since the publication of the first edition are taken into account and refered to when relevant.
