Nuclear power plants (NPPs) must operate in a manner that meets their design intent over a period of many decades. Maintaining the safe operation expected of a plant requires that the initial design (or any other design changes thereto during its lifetime) be implemented, recorded and controlled via a meticulous, adequate, and structured process.

Due to the nearly one century long lifetime of an NPP, changes may affect the effectiveness and adequacy of design information maintenance, updating, recording and retention. If design and configuration control are lost, it is essential that the the complete and correct reconstitution of design information will be efficient, effective and properly planned and scheduled, with an understanding of the extent of such efforts.

The purpose of the technical meeting is to provide a platform for Member States to share knowledge and experiences related to the loss and re-establishing of design basis, as well as to the maintenance and control of facility design and configuration that prevent such a loss or need for reconstitution. The meeting will also introduce the draft of a Technical Document developed by the IAEA?on Design Basis Reconstitution for Long Term Operation of Nuclear Power Plants and collect comments, input and feedback from Member States.

Those wishing to participate?in the meeting have to be designated by an IAEA Member State or should be members of organizations that have been invited to attend.
