This International Standard defines the essential technical requirements that must be addressed in the process of design and construction of Generation IV (GEN IV) nuclear reactors. It does not address operation, maintenance and in-service inspection of reactors.

Six reactor concepts are considered for GEN IV:

The Sodium Fast Reactor, The Lead Fast Reactor, The Gas Fast Reactor, The Very High Temperature Reactor, The SuperCritical Water Reactor and the Molten Salt Reactor.

Annex A details the main characteristics for the different concepts.

The scope of application of the standard is limited to mechanical components related to nuclear safety and to the prevention of the release of radioactive materials:

—    that are considered to be important in terms of nuclear safety and operability, and

—    that play a role in ensuring leaktightness, partitioning, guiding, securing and supporting,

—    that contain and/or are in contact with fluids (such as vessels, pumps, valves, pipes, bellows, box structures, heat exchangers, handling and driving mechanisms).

It is essential to apply this document if data concerning the deposition efficiency of a spray process in connection with a defined spray material are required.

This document describes the test implementation procedure to determine the deposition efficiency, supplying reliable comparison method between different spray processes and different feed stock. It is applicable for all thermal spray processes (see ISO 14917) and all wire, rod, cord and powder spray materials.

This document defines the basic terms relating to the design and operation of Reciprocating Internal Combustion (RIC) engines.

Further terms relating to components and systems of RIC engines are defined in the 12 parts of ISO 7967, and performance is defined in ISO 15550, ISO 14396 and in the six parts of ISO 3046.
