An inspection shall be deemed to be special when it is either additional to the routine inspection effort provided for in Articles 79 to 83 or involves access to information or locations in addition to the access specified in Article 77 for ad hoc and routine inspections, or both.
Scope of inspections
Article 75
For the purposes specified in Articles 72 to 74, the Agency may:
(a) Examine the records kept pursuant to Articles 52 to 59;
(b) Make independent measurements of all nuclear material subject to safeguards under this Agreement;
(c) Verify the functioning and calibration of instruments and other measuring and control equipment;

Article 76
Within the scope of Article 75, the Agency shall be enabled:
(a) To observe that samples at key measurement points for material balance accountancy are taken in accordance with procedures which produce representative samples, to observe the treatment and analysis of the samples and to obtain duplicates of such samples;
(b) To observe that the measurement of nuclear material at key measurement points for material balance accountancy are representative, and to observe the calibration of the instruments and equipment involved;
(c) To make arrangements with Australia that, if necessary:
(i) Additional measurements are made and additional samples taken for the Agency's use;
(ii) The Agency's standard analytical samples are analysed;
(iii) Appropriate absolute standards are used in calibrating instruments and other equipment; and
(iv) Other calibrations are carried out;
(d) To arrange to use its own equipment for independent measurement and surveillance, and if so agreed and specified in the Subsidiary Arrangements to arrange to install such equipment;
(e) To apply its seals and other identifying and tamper - indicating devices to containments, if so agreed and specified in the Subsidiary Arrangements; and
(f) To make arrangements with Australia for the shipping of samples taken for the Agency's use.
Access for inspections
Article 77
(a) For the purposes specified in Article 72(a) and (b) and until such time as the strategic points have been specified in the Subsidiary Arrangements, the Agency inspectors shall have access to any location where the initial report or any inspections carried out in connection with it indicate that nuclear material is present;
(b) For the purposes specified in Article 72(c) the inspectors shall have access to any location of which the Agency has been notified pursuant to Articles 93(d)(iii) or 96(d)(iii);
(c) For the purposes specified in Article 73 the inspectors shall have access only to the strategic points specified in the Subsidiary Arrangements and to the records maintained pursuant to Articles 52 to 59; and
(d) In the event of Australia concluding that any unusual circumstances require extended limitations on access by the Agency, Australia and the Agency shall promptly make arrangements with a view to enabling the Agency to discharge its safeguards responsibilities in the light of these limitations. The Director General shall report each such arrangement to the Board.
Article 78
In circumstances which may lead to special inspections for the purposes specified in Article 74, Australia and the Agency shall consult forthwith. As a result of such consultations the Agency may:
(a) Make inspections in addition to the routine inspection effort provided for in Articles 79 to 83; and
(b) Obtain access, in agreement with Australia, to information or locations in addition to those specified in Article 77. Any disagreement concerning the need for additional access shall be resolved in accordance with Articles 21 and 22; in case action by Australia is essential and urgent, Article 18 shall apply.
Frequency and intensity of routine inspections
Article 79
The Agency shall keep the number, intensity and duration of routine inspections, applying optimum timing, to the minimum consistent with the effective implementation of the safeguards procedures set forth in this Agreement, and shall make the optimum and most economical use of inspection resources available to it.
Article 80
The Agency may carry out one routine inspection per year in respect of facilities and material balance areas outside facilities with a content or annual throughput, whichever is greater, of nuclear material not exceeding five effective kilograms.
Article 81
The number, intensity, duration, timing and mode of routine inspections in respect of facilities with a content or annual throughput of nuclear material exceeding five effective kilograms shall be determined on the basis that in the maximum or limiting case the inspection regime shall be no more intensive than is necessary and sufficient to maintain continuity of knowledge of the flow and inventory of nuclear material, and the maximum routine inspection effort in respect of such facilities shall be determined as follows:
(a) For reactors and sealed storage installations the maximum total of routine inspection per year shall be determined by allowing one sixth of a man - year of inspection for each such facility;
(b) For facilities, other than reactors or sealed storage installations, involving plutonium or uranium enriched to more than 5%, the maximum total of routine inspection per year shall be determined by allowing for each such facility 30×  E man - days of inspection per year, where E is the inventory or annual throughput of nuclear material, whichever is greater, expressed in effective kilograms. The maximum established for any such facility shall not, however, be less than 1.5 man - years of inspection; and
(c) For facilities not covered by paragraphs (a) or (b), the maximum total of routine inspection per year shall be determined by allowing for each such facility one third of a man - year of inspection plus 0.4×E man - days of inspection per year, where E is the inventory or annual throughput of nuclear material, whichever is greater, expressed in effective kilograms.
Australia and the Agency may agree to amend the figures for the maximum inspection effort specified in this Article, upon determination by the Board that such amendment is reasonable.
Article 82
Subject to Articles 79 to 81 the criteria to be used for determining the actual number, intensity, duration, timing and mode of routine inspections in respect of any facility shall include:
(a) The form of the nuclear material, in particular, whether the nuclear material is in bulk form or contained in a number of separate items; its chemical composition and, in the case of uranium, whether it is of low or high enrichment; and its accessibility;
(b) The effectiveness of Australia's national accounting and control system, including the extent to which the operators of facilities are functionally independent of the national accounting and control system; the extent to which the measures specified in Article 33 have been implemented by Australia; the promptness of reports provided to the Agency; their consistency with the Agency's independent verification; and the amount and accuracy of the material unaccounted for, as verified by the Agency;
(c) Characteristics of Australia's nuclear fuel cycle, in particular, the number and types of facilities containing nuclear material subject to safeguards, the characteristics of such facilities relevant to safeguards, notably the degree of containment; the extent to which the design of such facilities facilitates verification of the flow and inventory of nuclear material; and the extent to which information from different material balance areas can be correlated;
(d) International interdependence, in particular, the extent to which nuclear material is received from or sent to other States for use or processing; any verification activities by the Agency in connection therewith; and the extent to which Australia's peaceful nuclear activities are interrelated with those of other States; and
(e) Technical developments in the field of safeguards, including the use of statistical techniques and random sampling in evaluating the flow of nuclear material.
Article 83
Australia and the Agency shall consult if Australia considers that the inspection effort is being deployed with undue concentration on particular facilities.
Notice of inspections
Article 84
The Agency shall give advance notice to Australia before arrival of inspectors at facilities or material balance areas outside facilities, as follows:
(a) For ad hoc inspections pursuant to Article 72(c), at least 24 hours; for those pursuant to Article 72(a) and (b) as well as the activities provided for in Article 49, at least one week;
(b) For special inspections pursuant to Article 74, as promptly as possible after the Agency and Australia have consulted as provided for in Article 78, it being understood that notification of arrival normally will constitute part of the consultations; and
(c) For routine inspections pursuant to Article 73, at least 24 hours in respect of the facilities referred to in Article 81(b) and sealed storage installations containing plutonium or uranium enriched to more than 5%, and one week in all other cases.
Such notice of inspections shall include the names of the inspectors and shall indicate the facilities and the material balance areas outside facilities to be visited and the periods during which they will be visited. If the inspectors are to arrive from outside Australia the Agency shall also give advance notice of the place and time of their arrival in Australia.
Article 85
Notwithstanding the provisions of Article 84, the Agency may, as a supplementary measure, carry out without advance notification a portion of the routine inspections pursuant to Article 81 in accordance with the principle of random sampling. In performing any unannounced inspections, the Agency shall fully take into account any operational programme provided by Australia pursuant to Article 65(b). Moreover, whenever practicable, and on the basis of the operational programme, it shall advise Australia periodically of its general programme of announced and unannounced inspections, specifying the general periods when inspections are foreseen. In carrying out any unannounced inspections, the Agency shall make every effort to minimize any practical difficulties for Australia and for facility operators, bearing in mind the relevant provisions of Articles 45 and 90. Similarly Australia shall make every effort to facilitate the task of the inspectors.
Designation of inspectors
Article 86
The following procedures shall apply to the designation of inspectors:
(a) The Director General shall inform Australia in writing of the name, qualifications, nationality, grade and such other particulars as may be relevant, of each Agency official he proposes for designation as an inspector for Australia;
(b) Australia shall inform the Director General within thirty days of the receipt of such a proposal whether it accepts the proposal;
(c) The Director General may designate each official who has been accepted by Australia as one of the inspectors for Australia, and shall inform Australia of such designations; and
(d) The Director General, acting in response to a request by Australia or on his own initiative, shall immediately inform Australia of the withdrawal of the designation of any official as an inspector for Australia.
However, in respect of inspectors needed for the activities provided for in Article 49 and to carry out ad hoc inspections pursuant to Article 72(a) and (b) the designation procedures shall be completed if possible within thirty days after the entry into force of this Agreement. If such designation appears impossible within this time limit, inspectors for such purposes shall be designated on a temporary basis.
Article 87
Australia shall grant or renew as quickly as possible appropriate visas, where required, for each inspector designated for Australia.
Conduct and visits of inspectors
Article 88
Inspectors, in exercising their functions under Articles 49 and 72 to 76, shall carry out their activities in a manner designed to avoid hampering or delaying the construction, commissioning or operation of facilities, or affecting their safety. In particular, inspectors shall not operate any facility themselves or direct the staff of a facility to carry out any operation. If inspectors consider that in pursuance of Articles 75 and 76, particular operations in a facility should be carried out by the operator, they shall make a request therefor.
Article 89
When inspectors require services available in Australia, including the use of equipment, in connection with the performance of inspections, Australia shall facilitate the procurement of such services and the use of such equipment by inspectors.
Article 90
Australia shall have the right to have inspectors accompanied during their inspections by representatives of Australia, provided that inspectors shall not thereby be delayed or otherwise impeded in the exercise of their functions.
STATEMENTS ON THE AGENCY'S VERIFICATION ACTIVITIES
Article 91
The Agency shall inform Australia of:
(a) The results of inspections, at intervals to be specified in the Subsidiary Arrangements; and
(b) The conclusions it has drawn from its verification activities in Australia, in particular by means of statements in respect of each material balance area, which shall be made as soon as possible after a physical inventory has been taken and verified by the Agency and a material balance has been struck.
INTERNATIONAL TRANSFERS
Article 92
General provisions
Nuclear material subject or required to be subject to safeguards under this Agreement which is transferred internationally shall, for purposes of this Agreement, be regarded as being the responsibility of Australia:
(a) In the case of import into Australia, from the time that such responsibility ceases to lie with the exporting State, and no later than the time at which the material reaches its destination; and
(b) In the case of export out of Australia, up to the time at which the recipient State assumes such responsibility, and no later than the time at which the nuclear material reaches its destination.
The point at which the transfer of responsibility will take place shall be determined in accordance with suitable arrangements to be made by the States concerned. Neither Australia nor any other State shall be deemed to have such responsibility for nuclear material merely by reason of the fact that the nuclear material is in transit on or over its territory or its territorial waters, or that it is being transported on a ship under its flag or in its aircraft.
Transfers out of Australia
Article 93
(a) Australia shall notify the Agency of any intended transfer out of Australia of nuclear material subject to safeguards under this Agreement if the shipment exceeds one effective kilogram, or if, within a period of three months, several separate shipments are to be made to the same State, each of less than one effective kilogram but the total of which exceeds one effective kilogram.
(b) Such notification shall be given to the Agency after the conclusion of the contractual arrangements leading to the transfer and normally at least two weeks before the nuclear material is to be prepared for shipping.
(c) Australia and the Agency may agree on different procedures for advance notification.
(d) The notification shall specify:
(i) The identification and, if possible, the expected quantity and composition of the nuclear material to be transferred, and the material balance area from which it will come;
(ii) The State for which the nuclear material is destined;
(iii) The dates on and locations at which the nuclear material is to be prepared for shipping;
(iv) The approximate dates of dispatch and arrival of the nuclear material; and
(v) At what point of the transfer the recipient State will assume responsibility for the nuclear material for the purpose of this Agreement, and the probable date on which that point will be reached.
Article 94
The notification referred to in Article 93 shall be such as to enable the Agency to make, if necessary, an ad hoc inspection to identify, and if possible verify the quantity and composition of the nuclear material before it is transferred out of Australia and, if the Agency so wishes or Australia so requests, to affix seals to the nuclear material when it has been prepared for shipping. However, the transfer of the nuclear material shall not be delayed in any way by any action taken or contemplated by the Agency pursuant to such a notification.
Article 95
If the nuclear material will not be subject to Agency safeguards in the recipient State, Australia shall make arrangements for the Agency to receive, within three months of the time when the recipient State assumes responsibility for the nuclear material from Australia, confirmation by the recipient State of the transfer.
Transfers into Australia
Article 96
(a) Australia shall notify the Agency of any expected transfer into Australia of nuclear material required to be subject to safeguards under this Agreement if the shipment exceeds one effective kilogram, or if within a period of three months, several separate shipments are to be received from the same State, each of less than one effective kilogram but the total of which exceeds one effective kilogram.
(b) The Agency shall be notified as much in advance as possible of the expected arrival of the nuclear material, and in any case not later than the date on which Australia assumes responsibility for the nuclear material.
(c) Australia and the Agency may agree on different procedures for advance notification.
(d) The notification shall specify:
(i) The identification and, if possible, the expected quantity and composition of the nuclear material;
(ii) At what point of the transfer Australia will assume responsibility for the nuclear material for the purpose of this Agreement, and the probable date on which that point will be reached; and
(iii) The expected date of arrival, the location where, and the date on which, the nuclear material is intended to be unpacked.
Article 97
The notification referred to in Article 96 shall be such as to enable the Agency to make, if necessary, an ad hoc inspection to identify, and if possible verify the quantity and composition of, the nuclear material at the time the consignment is unpacked. However, unpacking shall not be delayed by any action taken or contemplated by the Agency pursuant to such a notification.
Article 98
Special reports
Australia shall make a special report as envisaged in Article 69 if any unusual incident or circumstances, including the occurrence of significant delay, lead Australia to believe that there is or may have been loss of nuclear material during an international transfer.
Article 99
For the purposes of this Agreement:
A. Adjustment means an entry into an accounting record or a report showing a shipper/receiver difference or material unaccounted for.

(v) Retained waste: nuclear material generated from processing or from an operational accident, which is deemed to be unrecoverable for the time being but which is stored;
(vi) Exemption: exemption of nuclear material from safeguards on account of its use or quantity; and
(vii) Other loss: for example, accidental loss (that is, irretrievable and inadvertent loss of nuclear material as the result of an operational accident) or theft.
K. Key measurement point means a location where nuclear material appears in such a form that it may be measured to determine material flow or inventory. Key measurement points thus include, but are not limited to, the inputs and outputs (including measured discards) and storages in material balance areas.
L. Man - year of inspection means, for the purposes of Article 81, 300 man - days of inspection, a man - day being a day during which a single inspector has access to a facility at any time for a total of not more than eight hours.
M. Material balance area means an area in or outside of a facility such that:
(a) The quantity of nuclear material in each transfer into or out of each material balance area can be determined; and
(b) The physical inventory of nuclear material in each material balance area can be determined when necessary, in accordance with specified procedures,
in order that the material balance for Agency safeguards purposes can be established.
N. Material unaccounted for means the difference between book inventory and physical inventory.
O. Nuclear material means any source or any special fissionable material as defined in Article XX of the Statute. The term source material shall not be interpreted as applying to ore or ore residue. Any determination by the Board under Article XX of the Statute after the entry into force of this Agreement which adds to the materials considered to be source material or special fissionable material shall have effect under this Agreement only upon acceptance by Australia.
P. Physical inventory means the sum of all the measured or derived estimates of batch quantities of nuclear material on hand at a given time within a material balance area, obtained in accordance with specified procedures.
Q. Shipper/receiver difference means the difference between the quantity of nuclear material in a batch as stated by the shipping material balance area and as measured at the receiving material balance area.
R. Source data means those data, recorded during measurement or calibration or used to derive empirical relationships, which identify nuclear material and provide batch data. Source data may include, for example, weight of compounds, conversion factors to determine weight of element, specific gravity, element concentration, isotopic ratios, relationship between volume and manometer readings and relationship between plutonium produced and power generated.
S. Strategic point means a location selected during examination of design information where, under normal conditions and when combined with the information from all strategic points taken together, the information necessary and sufficient for the implementation of safeguards measures is obtained and verified; a strategic point may include any location where key measurements related to material balance accountancy are made and where containment and surveillance measures are executed.
