It applies to centralized systems having a direct role in the achievement or maintenance of radiation protection in nuclear facilities. These systems perform functions such as:<\/p>\n<ul>\n<li>\n<p>radiation protection of plant discharge;<\/p>\n<\/li>\n<li>\n<p>interlock of control functions to prevent or to mitigate accidental release of radioactive material;<\/p>\n<\/li>\n<li>\n<p>radiation and environmental monitoring functions to support monitoring of and response to accidents;<\/p>\n<\/li>\n<li>\n<p>provide information to process control or safety systems for use in control or interlock functions.<\/p>\n<\/li>\n<\/ul>\n<p>This document defines the communication criteria to link distributed radiation monitoring equipment in the facility, integrates data processing, storage, optimization, and correlation of data flow and displays, and provides criteria for the interface between monitors of different safety classes.<\/p>\n<p>It will not directly apply to the design and testing of detection and measurement assemblies except as necessary to define the interface with the central computer. Requirements for these assemblies are contained in existing standards.<\/p>\n<p>This document describes the integration of functions including equipment such as those described in IEC 60761-1, IEC 60761-2, IEC 60761-3, IEC 60761-4, IEC 60761-5, IEC 60768, IEC 60861, IEC 60910, IEC 60951-1 IEC 60951-2, IEC 60951-3, IEC 60951-4, IEC 60951-5, IEC 61031, IEC 61250, IEC 62302 and IEC 62303, into a centralized system. The requirements of system-level components (central computer, subsystem computers, operator consoles, and interconnections) are discussed. For detector assemblies, processing assemblies and alarm assemblies, this document contains only the requirements needed to allow connection into the central computer. The standards referenced above contain the specific requirements for these components.<\/p>\n<p>This document identifies requirements pertinent to the integration of the above functions into a centralized system. Requirements for general and design characteristics, electrical performance requirements and tests, mechanical performance and tests, software performance requirements and tests, environmental characteristics performance requirements and tests and documentation are considered by referring to IEC 62705.<\/p>\n<p>Certain complete centralized systems for radiation monitoring may be entirely implemented with direct-connected analogue\/relay technology. This document does not apply to such systems.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>undefined  <\/td>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>English <br \/> CONTENTS  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>FOREWORD  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>INTRODUCTION  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>Table 1 \u2013 Overview of the standards coveringthe domain of radiation monitoring in nuclear facilities  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>1 Scope <br \/> 2 Normative references  <\/td>\n<\/tr>\n<tr>\n<td><b>15<b><\/td>\n<td>3 Terms and definitions  <\/td>\n<\/tr>\n<tr>\n<td><b>16<b><\/td>\n<td>4 Design requirements <br \/> 4.1 General <br \/> 4.1.1 Background  <\/td>\n<\/tr>\n<tr>\n<td><b>17<b><\/td>\n<td>4.1.2 General characteristics and lifecycle (IEC 61559-1:2009, 4.1.1) <br \/> 4.1.3 Safety classification and applicable standards (IEC 61559-1:2009, 4.1.2) <br \/> 4.1.4 System architecture and configuration (IEC 61559-1:2009, 4.1.3)  <\/td>\n<\/tr>\n<tr>\n<td><b>19<b><\/td>\n<td>4.1.5 Location of detector assemblies (IEC 61559-1:2009, 4.1.4) <br \/> Figure 1 \u2013 Example of a typical centralized system configuration  <\/td>\n<\/tr>\n<tr>\n<td><b>20<b><\/td>\n<td>4.1.6 Failure mode <br \/> 4.1.7 Interlock functions <br \/> 4.1.8 Control functions <br \/> 4.1.9 Control of access <br \/> 4.1.10 Testability  <\/td>\n<\/tr>\n<tr>\n<td><b>21<b><\/td>\n<td>4.1.11 Maintainability <br \/> 4.1.12 Operator interface <br \/> 4.1.13 Data communication <br \/> 4.2 Design requirements for the subassemblies <br \/> 4.2.1 Detector assembly (IEC 61559-1:2009, 4.2.1) <br \/> 4.2.2 Processing assembly (IEC 61559-1:2009, 4.2.2)  <\/td>\n<\/tr>\n<tr>\n<td><b>22<b><\/td>\n<td>4.2.3 Alarm assembly (IEC 61559-1:2009, 4.2.3) <br \/> 4.2.4 Subsystem computer <br \/> 4.2.5 Operator console <br \/> 4.2.6 Interconnections <br \/> 4.3 Central computer <br \/> 4.3.1 General (IEC 61559-1:2009, 4.3.1) <br \/> 4.3.2 Functional requirements of the central computer (IEC 61559-1:2009, 4.3.2)  <\/td>\n<\/tr>\n<tr>\n<td><b>23<b><\/td>\n<td>4.3.3 Checking normal operation of the equipment (IEC 61559-1 4.3.3)  <\/td>\n<\/tr>\n<tr>\n<td><b>24<b><\/td>\n<td>4.3.4 Modifications <br \/> 4.3.5 Recommended features  <\/td>\n<\/tr>\n<tr>\n<td><b>25<b><\/td>\n<td>4.4 Electrical characteristics <br \/> 4.4.1 General (IEC 61559-1:2009, 4.4.1) <br \/> 4.4.2 Electromagnetic compatibility (IEC 61559-1:2009, 4.4.2) <br \/> 4.5 Radiation monitoring functions <br \/> 5 General test procedures <br \/> 5.1 General <br \/> 5.2 Test requirements (IEC 61559-1:2009, 5.1) <br \/> 5.3 Test procedures for subassemblies <br \/> 5.3.1 Test procedures for the detector assembly (IEC 61559-1:2009, 5.2) <br \/> 5.3.2 Test procedures for the combination of processing, detector and alarm assemblies (IEC 61559-1:2009, 5.3)  <\/td>\n<\/tr>\n<tr>\n<td><b>26<b><\/td>\n<td>5.3.3 Test procedures for subsystem computer <br \/> 5.3.4 Test procedures for operator consoles <br \/> 5.4 Test procedures for the central computer (IEC 61559-1:2009, 5.4) <br \/> 5.5 Test procedures for effects of power supply and environmental variations (IEC 61559-1:2009, 5.5) <br \/> 5.6 Test procedures for data communications <br \/> 5.7 System validation  <\/td>\n<\/tr>\n<tr>\n<td><b>27<b><\/td>\n<td>5.8 System installation and commissioning testing <br \/> 5.9 System qualification <br \/> 6 Documentation <br \/> 6.1 General <br \/> 6.2 Report on type testing (IEC 61559-1:2009, 6.1) <br \/> 6.3 Certification (IEC 61559-1:2009, 6.2)  <\/td>\n<\/tr>\n<tr>\n<td><b>28<b><\/td>\n<td>6.4 Operating and maintenance manual (IEC 61559-1:2009, 6.3) <br \/> 6.5 Additional documentation <br \/> Table 2 \u2013 Reference conditions and standard test conditions (unless otherwise indicated by the supplier)  <\/td>\n<\/tr>\n<tr>\n<td><b>29<b><\/td>\n<td>Annex A (informative)Cross-references for centralized systemfor radiation monitoring standards <br \/> Table A.1 \u2013 Cross-reference table for centralizedsystem for radiation monitoring standards  <\/td>\n<\/tr>\n<tr>\n<td><b>32<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Nuclear facilities.
