DESIGN INFORMATION
QUESTIONNAIRE *
IAEA USE ONLY

The purpose of this document is to
obtain the facility design information
required by the Agency in order to
discharge its safeguards responsibilities.
It will also serve as a checklist for
examination of design information by
Agency inspector(s). If, in any area,
insufficient space is available add further
shee ts to the extent necessary.
