This Standard covers the management of cleaning and cleanness control of fluid systems and associated components for nuclear power plants during manufacturing, construction, repairs, and modifications. The Standard includes requirements for cleaning and cleanness control of fluid systems and components which have been identified as "safety related." These requirements should also be considered in the cleaning and cleanness control of other fluid systems and components. The Standard covers factors that shall be considered to ensure an adequately clean fluid system or component upon the completion of manufacturing, construction, repair, or modification activities and covers all periods in which these activities are conducted. This Standard is not a procedure for cleaning and cleanness control, but provides a basis for development of such procedures.

This Standard requires close attention to cleanness control during these activities so that only flushing or rinsing may be required to render the item ready for service. When more than a flush or rinse is needed to produce the specified cleanness, additional cleaning, in accordance with this Standard, may be necessary.

This Standard is not intended to be used for items containing liquid metals in liquid metal-cooled power plants. This Standard is not intended to provide guidance for decontamination of radioactively contamined items although its requirements may be invoked in such operations if considered appropriate.

This Standard is intended to be used in conjunction wifh ANSI N45.2, Quality Assurance Program Requirements for Nuclear Power Plants.
