General

This International Standard provides requirements for achieving highly reliable “HDL-Programmed Devices” (HPD), for use in I&C systems of nuclear power plants performing functions of safety category B or C as defined by IEC 61226.

The programming of HPDs relies on Hardware Description Languages (HDL) and related software tools. They are typically based on blank Field Programmable Gate Arrays (FPGAs) or similar micro-electronic technologies such as Programmable Logic Devices (PLD), Complex Programmable Logic Devices (CPLD), etc. General purpose integrated circuits such as microprocessors are not HPDs.

This Standard provides requirements on:

a)  a dedicated HPD life-cycle addressing each phase of the development of HPDs, including specification of requirements, design, implementation, integration and validation, as well as verification activities associated with each phase,

b)  planning and complementary activities such as modification and production,

c)  selection of pre-developed components. This includes micro-electronic resources  Pre-Developed Blocks (PDB),

d)  tools used to design, implement and verify HPDs.

This Standard does not put requirements on the development of the micro-electronic resources, which are usually available as "commercial off-the-shelf" items and are not developed under nuclear quality assurance Standards. It addresses the developments made with these micro-electronic resources in an I&C project with HDLs and related tools.

This Standard provides guidance to avoid as far as possible latent faults remaining in HPDs, and to reduce the susceptibility to single failures as well as to potential Common Cause Failures (CCF).

Reliability aspects related to environmental qualification and failures due to ageing or physical degradation are not handled in this Standard. Other Standards, especially IEC 60987, IEC/IEEE 60780-323 and IEC 62342, address these topics.

This standard does not cover cybersecurity for HDL aspects of I&C systems. IEC 62645 provides requirements for security programmes for I&C programmable digital systems.

Use of this Standard

This Standard provides guidance and requirements to produce verifiable HPD designs and implementations requiring justification due for example to the importance to safety of their function or behaviour. This Standard describes the activities to develop HPDs, organized in the framework of a dedicated life-cycle. It also describes activities and guidelines to be used in addition to the requirements of IEC 61513 for system integration and validation when HPDs are included.

This International Standard applies to installed dose equivalent rate meters, warning assemblies and monitors, as defined below. It covers equipment intended to measure neutron radiation in dose equivalent rates in the energy region between thermal and 20 MeV for the purposes of radiation protection.

Assemblies of this type are commonly defined as area radiation monitors. They are normally employed to determine continuously the radiological situation in working areas in which the radiation field may change with time, for example, nuclear power plants, particle accelerators, high-activity laboratories, fuel reprocessing plants etc., and provide alarms when the radiation field goes outside predetermined limits.

The assemblies considered in this standard comprise at least:

a detector assembly, which may, for example, consist of a detector probe (for thermal neutrons such as BF3 proportional counter, 3He proportional counter, 6LiI(Tl) scintillation detector, etc.) and a moderating and absorbing medium surrounding the detector;

a processing assembly, which may be fitted into a centralized panel, which, in the case of warning assemblies and monitors, provides signal outputs and contacts capable of activating alarm or other trip circuits.

Alternatively, the case when all the processing electronics are placed within the detection unit (so called "smart blocks") may be considered. In this case the functions of the processing assembly will be composed of only the indication, the providing signal outputs and contacts.

This standard specifies general characteristics, general test procedures, radiation characteristics, as well as electrical, mechanical, safety, and environmental characteristics, as well as the identification certificate for the assemblies defined in the scope.

Assemblies designed to perform combined functions shall comply with the requirements pertaining to each of these functions.

This standard is not applicable to criticality monitors covered by IEC 60860, or to assemblies intended to give information about operational parameters of nuclear plants for control purposes. This standard is not applicable to the operating characteristics of indicating or recording instruments as such (for instance, indicating meters, recorders, etc.). The characteristics of such instruments shall be in conformity with the general requirements appropriate to them.

This standard does not cover hand-held neutron dose (rate) meters and instruments that are covered in IEC 61005.

No tests are specified in this standard for performance requirements in pulsed radiation fields. It is understood that an assembly designed to meet this standard may not be suitable for use in this fields.

This part describes the OPC Unified Architecture (OPC UA) Profiles. The Profiles in this document are used to segregate features with regard to testing of OPC UA products and the nature of the testing (tool based or lab based). This includes the testing performed by the OPC Foundation provided OPC UA CTT (a self-test tool) and by the OPC Foundation provided Independent certification test labs. This could equally as well refer to test tools provided by another organization or a test lab provided by another organization. What is important is the concept of automated tool based testing versus lab based testing. The scope of this standard includes defining functionality that can only be tested in an a lab and defining the grouping of functionality that is to be used when testing OPC UA products either in a lab or using automated tools. The definition of actual TestCases is not within the scope of this document, but the general categories of TestCases are within the scope of this document.

Most OPC UA applications will conform to several, but not all of the Profiles.

This specification defines the Information Model of the OPC Unified Architecture. The Information Model describes standardised Nodes of a Server’s AddressSpace. These Nodes are standardised types as well as standardised instances used for diagnostics or as entry points to server-specific Nodes. Thus, the Information Model defines the AddressSpace of an empty OPC UA Server. However, it is not expected that all Servers will provide all of these Nodes.

This specification defines the OPC Unified Architecture (OPC UA) Services. The Services described are the collection of abstract Remote Procedure Calls (RPC) that are implemented by OPC UA Servers and called by OPC UA Clients. All interactions between OPC UA Clients and Servers occur via these Services. The defined Services are considered abstract because no particular RPC mechanism for implementation is defined in this part. IEC 62541-6 specifies one or more concrete mappings supported for implementation. For example, one mapping in IEC 62541-6 is to XML Web Services. In that case the Services described in this part appear as the Web service methods in the WSDL contract.

Not all OPC UA Servers will need to implement all of the defined Services. IEC 62541-7 defines the Profiles that dictate which Services need to be implemented in order to be compliant with a particular Profile.

This specification defines the OPC Unified Architecture (OPC UA) PubSub communication model. It defines an OPC UA publish subscribe pattern which complements the client server pattern defined by the Services in IEC 62541-4. See IEC TR 62541-1 for an overview of the two models and their distinct uses.

PubSub allows distributing data and events from an OPC UA information source to interested observers inside a device network as well as in IT and analytics cloud systems.

The specification consists of

a general introduction of the PubSub concepts,

a definition of the PubSub configuration parameters,

mapping of PubSub concepts and configuration parameters to messages and transport protocols,

and a PubSub configuration model.

Not all OPC UA Applications will need to implement all defined message and transport protocol mappings. IEC 62541-7 defines the Profile that dictate which mappings need to be implemented in order to be compliant with a particular Profile.

This part of IEC 60479 describes the effects on the human body when a sinusoidal alternating current in the frequency range above 100 Hz passes through it.

The effects of current passing through the human body for:

< > sinusoidal current with DC components,< > sinusoidal current with phase control, and< > sinusoidal current with multicycle control

are given but are only deemed applicable for alternating current frequencies from 15 Hz up to 100 Hz.

Means of extending the frequency of applicability of pure sinusoids to a frequency of 150 kHz are given, supplementing the data in IEC 60479-1.

Means of examining random complex irregular waveforms are given.

This document describes the effects of current passing through the human body in the form of single and multiple successive unidirectional rectangular impulses, sinusoidal impulses and impulses resulting from capacitor discharges.

The values specified are deemed to be applicable for impulse durations from 0,1 ms up to and including 10 ms.

This document only considers conducted current resulting from the direct application of a source of current to the body, as does IEC 60479-1. It does not consider current induced within the body caused by its exposure to an external electromagnetic field.

This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It is not intended for use by manufacturers or certification bodies.

One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications.
