Background Information

The document is a new safety guide in the IAEA Safety Standards Series. The information is based on SSR-2/1 (Rev.1) and some safety guides.

Although there is a separate dedicated section identifying requirements for Auxiliary systems and supporting systems

  • No definition of Auxiliary systems and supporting systems exists in the IAEA Safety Glossary;
  • Recommendations to meet requirements related to Auxiliary systems and supporting systems are found in different safety guides;
  • Not all the important Auxiliary systems and supporting systems are included in those safety guides;
  • Need to develop a corresponding Safety Guide
     

The Safety Guide was initiated to

  • comply with the long term structure of safety standards approved in 2008
  • comply with the safety standards in force at the time of the development
  • provide a definition of “Auxiliary systems and supporting systems” to be included in the IAEA Safety Glossary
  • clearly identify all relevant cross-references to the relevant existing safety guides, to identify possible gaps and to avoid duplication of recommendations
  • provide guidance to meet the requirements for Auxiliary systems and supporting systems, and
  • for preparing and reviewing the corresponding sections of the Safety Analysis Report related to Auxiliary systems and supporting systems.
