This paper discusses the processes and steps that Australia hastaken to ensure that its replacement research reactor (including nuclear material) will beeffectively protected against sabotage and theft. It also describes the legal basis of theAustralian Safeguards and Non-Proliferation Office (ASNO), Australian RadiationProtection and Nuclear Safety Agency (ARP ANSA), Australian Nuclear Science andTechnology Organisation (ANSTO), and Australian Security and IntelligenceOrganisation (ASIO). The inter-agency process is also outlined. ASNO and ARP ANSAhave responsibilities to satisfy themselves about the adequacy of the security system forANSTO's replacement research reactor (RRR). ANSTO is responsible for preparing asecurity plan and for implementing the security system set out in this plan for theprotection of nuclear material and nuclear facilities against sabotage, damage, theft, lossor unauthorized use. Meanwhile, ASIa plays a key role in developing the threatassessment and aspects of physical security. The design process of RRR physicalprotection system is included in this paper.
