The Working Group's mission is to provide the safeguards community with expert advice on containment and surveillance (C/S) instruments and methods and on their performance; and act as a forum for the exchange of information on such instruments and methods, including unattended and remote monitoring systems.

Terms of Reference


To provide the Safeguards Community with expert advice on Containment and Surveillance (C/S) instruments and methods and on their performance; and act as a forum for the exchange of information on such instruments and methods, which are considered to include unattended and remote monitoring systems.


To achieve the above objectives the C/S Working Group will:

  1. Advise the European Commission and IAEA on new and improved instruments and methods and on areas where R&D effort is still needed.
  2. Maintain a list of C/S instruments and methods currently used or under development for safeguards purposes.
  3. Develop methods for determining the assurance and performance of C/S equipment and contribute to their evaluation.
  4. Contribute to determining, on request, the assurance and performance of C/S equipment.
  5. Promote cooperation with other working groups and the inspection authorities.
  6. Assist in the development of C/S instruments and methods in support of safeguards approaches including the definition of technical requirements.
  7. Assist in the development and assessment of data evaluation and decision tools.
  8. Collaborate with other working groups to develop comprehensive and integrated tools to support safeguards approaches.
  9. Promote the exchange of information and experience among facility operators, safeguards authorities, and developers.
  10. Study technical characteristics of instruments and devices from other domains (e.g., physical protection) and investigate into the possible transfer of technology from these domains to the safeguards area.
  11. Look at other verification regimes and assess to what extent their techniques and methods could be used for safeguards.

C/S Compendium

At a workshop held in Salamanca in 1992, by the ESARDA Working Group on Containment and Surveillance, it was concluded that the development of containment and surveillance (C/S) devices had now reached a stage where products or basic expertise were available to assist with the solution of many problems.  It was felt that a compilation, which contained outline information on a range of C/S products would help the potential user to know where to obtain further information and, thus, to judge whether a particular device might meet the requirements of a specific application.

The Compendium also complies with the ‘ESARDA Strategic Planning’ initialised in 1998.

This compendium is not intended to be comprehensive but collects together contributions provided by the members of the Working Group.
