For each material balance area (summarised in Table 3), ASNO provided reports to the IAEA as required by the Comprehensive Safeguards Agreement. Report statistics are summarised in Tables 4 and 5. The high number of reports in Table 4 attributed to 'other locations' primarily relates to small holdings of uranium and thorium compounds at universities and research institutions.

Table 6 is a summary of total quantities of nuclear material by category in Australia. A small quantity (2.7 kg) of 235U in high enriched uranium is retained in Australia and used for a variety of purposes primarily due to the utility of the particular chemical, physical and isotopic characteristics. Typical uses of this material include: research and development related to nuclear non-proliferation activities; validating the commercial application of ANSTO's Synroc waste immobilisation technology; nuclear forensics for identifying illicit nuclear materials; development of detection technologies and chemistry work. The quantity comprises several items in various locations around Australia such as ANSTO and some universities.

As well as requiring reporting on nuclear material inventory and transactions, the Comprehensive Safeguards Agreement also requires reporting on design and operational attributes (relevant to safeguards) of nuclear facilities. This information is provided to the IAEA in Design Information Questionnaires (DIQs) for each facility MBA, and in the case of MBAs for locations outside facilities (LOFs), in LOF information questionnaires. No DIQs were updated during the reporting period.

The Safeguards Act requires permits for possession of nuclear material, as well as associated material, associated equipment and associated technology (collectively termed associated items). Permits for associated items ensure Australia can maintain regulatory controls on technology, equipment and material with potential proliferation risks, can report on design attributes for DIQs, and meet other reporting obligations under various nuclear cooperation agreements. Table 7 lists the inventory of associated items in Australia.

Reporting Obligations under the Australia– IAEA Additional Protocol

The Additional Protocol gives the IAEA greater access to information and locations related to nuclear fuel cycle activities, thereby allowing the IAEA to provide greater assurances not only that all declared nuclear material is accounted for, but also that states do not have any undeclared nuclear material or activities. Australia was the first country to sign and ratify an Additional Protocol with the IAEA, which came into force for Australia on 12 December 1997.

ASNO prepares and provides annual declarations under a range of Additional Protocol categories, as well as quarterly declarations on relevant exports. Table 8 lists the number of entries made under each category. An important aspect of the Additional Protocol is reporting to the IAEA on nuclear fuel cycle related research and development activities. ASNO ensured that all IAEA requirements were met during the reporting period with respect to nuclear research and development.

Safeguards Developments in Australia

The IAEA implements safeguards in Australia in accordance with the provisions in a range of legal instruments: the Comprehensive Safeguards Agreement; Additional Protocol; Subsidiary Arrangements; facility attachments and LOF attachments for each material balance area (MBA). Australia's MBAs are described in Table 3. The overarching framework the IAEA uses to prioritise and optimise various in-field verification and headquarters (i.e. at the IAEA) analysis activities under these instruments is the State-level approach (SLA) for Australia, which the IAEA updated in 2016 and is currently reviewing under the IAEA's SLA Improvement Project.

In Australia, the IAEA and ASNO apply most of their respective safeguards efforts to the Australian Nuclear Science and Technology Organisation (ANSTO), particularly safeguards aspects of the ANSTO Nuclear Medicine (ANM) project. At full operation, ANM has the capacity to supply a significant proportion (up to 25 per cent) of the world's requirements for molybdenum–99 (Mo–99), the parent product of the world's most widely used nuclear medicine, technetium–99m. ANSTO's permit issued under the Safeguards Act to establish its SyMo facility (Synroc Waste Immobilisation Facility) was extended by the Minister for Foreign Affairs, Senator Marise Payne, to cover construction delays.

All entities holding a permit to possess nuclear material are required to conduct an annual physical inventory taking (a stocktake of nuclear material held). As first done in 2020, ASNO adjusted procedures for the physical inventory taking at small permit holders (primarily comprising radiographers, universities, laboratories and state regulators) in 2021 to allow flexibility for COVID-impacted industries that could not readily conduct inventory-taking during June/July 2021. However, the multiple COVID-related lockdowns, especially in Sydney and Melbourne, resulted in two permit holders being unable to complete their physical inventory taking and associated reporting in time for ASNO to meet its reporting deadline to the IAEA (30 July). ASNO worked with these permit holders to obtain a "book inventory" based on the best information available to them. Formal physical inventory taking will be pursued once the lockdown periods end.

ASNO continues to engage with the Australian Radioactive Waste Agency (ARWA) in its mandate to establish a facility for Australia's radioactive waste. During the reporting period, ASNO assisted ARWA in its project of establishing a Common National Inventory for Radioactive Waste.

Permits and Authorities System

ASNO continued to operate Australia's state system of accounting for and control of nuclear material (SSAC) in accordance with Australia's Comprehensive Safeguards Agreement with the IAEA and national legislation. Australia's SSAC is implemented through permits issued under the Safeguards Act. Notices of all permit changes were published in the Australia Government Gazette as required by subsection 20(1) of the Safeguards Act. A summary of all permits granted, varied, revoked and expired in the reporting period is in Table 9.

Table 9: Status of Permits and Authorities under the Safeguards Act at 30 June 2021 and Changes in the Reporting Period
Permit or authority Current total Granted Varied Revoked Expired
Possess nuclear material 110 6 92 3 4
Possess associated items 10 0 2 0 0

Establish a facility 1 0 1 0 0
Decommission a facility 2 1 0 0 0
Communicate information contained in associated technology 7 0 1 0 0
Total 151 9 96 3 4

The conditions and restrictions set in ASNO's permits and authorities are customised to the activities relevant to the possession and transport of nuclear material and associated items and also to the relevant industry involved (e.g. research, radiography, mining, patent services). A summary of these permit classes is listed in Table 10. A high-level plan for the revision of all permits and authorities was established in August 2020. In 2020–21, 96 permits and authorities (including nearly all Class L, R and U6 permits) were revised under this plan. In 2021–22 all Class U2, U3, T1 & T2 permits and ANSTO's S1 permit are scheduled for revision.

Essential for the operation of the permit system is a fit-for-purpose database for managing permits and preparing routine reports on nuclear material inventory and transactions to the IAEA. ASNO continued to work with the database development team (under DFAT's Information Management Division) on the continuing development of ASNO's NUMBAT database.

During the reporting period, the IAEA conducted inspections in accordance with standard arrangements under Australia's Comprehensive Safeguards Agreement and the Additional Protocol. In the reporting period, the IAEA made three separate visits to Australia. On each occasion, the IAEA inspectors spent two weeks in quarantine before conducting their inspections. Details on all inspections are provided in Table 11, and the IAEA's findings from these inspections (where available at the time of publishing this Annual Report) are listed in Appendix B.

ASNO officers facilitated access for the IAEA inspectors in accordance with conditions under respective permits issued under the Safeguards Act and accompanied the inspectors during all of their activities.

In August 2020, the IAEA conducted verification of the uranium content in solid waste from molybdenum–99 (Mo–99) radiopharmaceutical production using an active well coincidence counter (AWCC). This first formal use of the AWCC in Australia followed successful hot commissioning of the detector in 2019. This inspection addressed the issue previously identified by the IAEA of the build-up of otherwise unverified nuclear material (see findings of material balance area AS-C page 96 of the 2019–20 ASNO Annual Report). Following verification with the AWCC, the IAEA applied dual containment seals to verified waste in storage.

The IAEA conducted a short notice random inspection in April 2021 and its annual, scheduled Physical Inventory Verification (PIV) inspections in June 2021. The IAEA also conducted a Complementary Access at the Honeymoon uranium mine (currently under care and maintenance) in June 2021.

Overall, the IAEA has maintained the "broader conclusion" for Australia that "all nuclear material remained in peaceful activities" (see Appendix B).

ASNO Inspections

During 2020–21, ASNO accompanied the IAEA on all the inspections listed above to ensure Australia's obligations were met in a timely and efficient manner and to ensure the inspections were conducted effectively.

The IAEA holds inspections to help it draw its conclusions on the correctness and completeness of Australia's nuclear accounting reports and safeguards declarations. ASNO inspectors are able also to use these opportunities to observe the inspected organisation's performance against their domestic permit conditions. This proves an efficient mechanism for ASNO's stakeholder outreach on regulatory requirements.

In addition to the IAEA inspections, ASNO continued to assist CSIRO and other permit holders with characterising legacy items of nuclear material and adding them to the inventory records. ASNO visited the NSW Environment Protection Authority (NSW EPA) radioactive store for which re-characterisation of its inventory had been partially completed. ASNO provided advice and recommendations on required actions for NSW EPA to satisfactorily establish and maintain the nuclear material inventory for the store.

Inventory balances

ASNO performed the annual material balance evaluation of the nuclear inventory accounts for each MBA with minor differences between book and physical inventory. These inventory differences were reported to the IAEA in conjunction with inventory change reports and physical inventory listings. Details are provided in Table 12. Differences were due to re-measurement of small batches of nuclear material at universities and research institutes and approximately 0.2 kilograms of mis-located items of depleted uranium and thorium for which investigations were pending the cessation of COVID-related lockdowns.

Table 12: Inventory Differences Recorded during 2020–21
