This Final Draft International Standard is an up to 6 weeks' pre-release of the official publication. It is available for sale during its voting period: 2021-06-11 to 2021-07-23. By purchasing this FDIS now, you will automatically receive, in addition, the final publication.
IEC 63186:2021 specifies the minimum requirements for the design of the seismic trip system, and the components thereof, used in a nuclear power plant to mitigate seismic effects. This system is intended to shut down the reactor in operation automatically before it is significantly impacted by the vibratory ground motion incurred by strong earthquakes. This document is applicable to both the design of new built plants and the upgrading of plants in operation. It may be used for the design of other types of nuclear facilities where normal operation shall be stopped in case of strong seismic motions.

IEC 63147:2017(E) contains the functional and design criteria for accident monitoring instrumentation for new plant designs and nuclear power generating stations desiring to perform design modifications. The purpose of this standard is to establish selection, design, performance, qualification, and display criteria for accident monitoring instrumentation for anticipated operational occurrences, design basis events, and severe accidents.
This standard applies to accident monitoring instrumentation intended for use during the following operations:
- As required for planned operator action related to accident mitigation,
- For assessing plant conditions, safety system performance, and making decisions related to plant response to abnormal events,
- For achieving and maintaining safe shutdown following an accident
This standard does not apply to the following:
- Accident monitoring instrumentation that is intended solely for historical recording or solely for maintenance purposes
- Other instrumentation that may be available during accident conditions.
This standard is an adoption of IEEE 497-2016 by IEC.
When applied in an IAEA / IEC environment this standard is to be used in conjunction with IEC TR 63123.Technology -

IEC 63132-4:2020 The purpose of this this part of IEC 63132 is to establish, in a general way, suitable procedures and tolerances for the installation of a vertical Kaplan or propeller turbine. This document presents a typical assembly and whenever the word “turbine” is used in this document, it refers to a vertical Kaplan or propeller turbine. There are many possible ways to assemble a unit. The size of the machine, design of the machine, layout of the powerhouse or delivery schedule of the components are some of the elements that could result in additional steps, the elimination of some steps and/or assembly sequences.
It is understood that a publication of this type will be binding only if, and to the extent that, both contracting parties have agreed upon it.
This document excludes matters of purely commercial interest, except those inextricably bound up with the conduct of installation.
The tolerances in this document have been established upon best practices and experience, although it is recognized that other standards specify different tolerances.
Wherever this document specifies that documents, drawings or information is supplied by a manufacturer (or by manufacturers), each individual manufacturer will furnish the appropriate information for their own supply only.Technology -
