in the information provided to it under Article 45, sufficiently in advance for the safeguards procedures to be adjusted when necessary.

Article 47
                   Purposes of examination of design information
The design information provided to the Agency shall be used for the following purposes:
    (a) To identify the features of facilities and nuclear material relevant to the application of safeguards to nuclear material in sufficient detail to facilitate verification;
    (b) To determine material balance areas to be used for Agency accounting purposes and to select those strategic points which are key measurement points and which will be used to determine flow and inventory of nuclear material; in determining such material balance areas the Agency shall, inter alia, use the following criteria:
          (i) The size of the material balance area shall be related to the accuracy with which the material balance can be established;
          (ii) In determining the material balance area advantage shall be taken of any opportunity to use containment and surveillance to help ensure the completeness of flow measurements and thereby to simplify the application of safeguards and to concentrate measurement efforts at key measurement points;
          (iii) A number of material balance areas in use at a facility or at distinct sites may be combined in one material balance area to be used for Agency accounting purposes when the Agency determines that this is consistent with its verification requirements; and
          (iv) A special material balance area may be established at the request of Australia around a process step involving commercially sensitive information;
    (c) To establish the nominal timing and procedures for taking of physical inventory of nuclear material for Agency accounting purposes;
    (d) To establish the records and reports requirements and records evaluation procedures;
    (e) To establish requirements and procedures for verification of the quantity and location of nuclear material; and
    (f) To select appropriate combinations of containment and surveillance methods and techniques and the strategic points at which they are to be applied.
The results of the examination of the design information shall be included in the Subsidiary Arrangements.

Article 48
                   Re‑examination of design information
Design information shall be re‑examined in the light of changes in operating conditions, of developments in safeguards technology or of experience in the application of verification procedures, with a view to modifying the action the Agency has taken pursuant to Article 47.

Article 49
                   Verification of design information
The Agency, in co‑operation with Australia, may send inspectors to facilities to verify the design information provided to the Agency pursuant to Articles 43 to 46, for the purposes stated in Article 47.

INFORMATION IN RESPECT OF NUCLEAR MATERIAL OUTSIDE FACILITIES
Article 50
The Agency shall be provided with the following information when nuclear material is
