The NRC provides regulatory oversight of nuclear power plant safety through its routine inspection program, as well as assessments where a specially trained simulated adversary attacks the plant. The agency conducts these force-versus-force exercises at each nuclear power plant at least once every three years. According to Selena Ng, Areva's director for Southeast Asia and Oceania, the Fukushima nuclear disaster in Japan is a huge wake-up call for a nuclear industry that hasn't always been transparent enough on safety issues. Nuclear weapons security, as well as the security of military research involving nuclear materials, is generally handled by agencies other than those overseeing civil security, for a number of reasons, including secrecy.
The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) is the Federal Government body that monitors and identifies the risks of solar radiation and nuclear radiation in Australia. Based on the knowledge of these studies, additional mitigation capabilities were put in place at all nuclear power plants. An effective physical protection system takes into account the particular nuclear installation, the type of nuclear material used in it and the threat, as well as the consequences (radiological and otherwise), should prevention fail. Today, nuclear facilities regulated by the NRC are considered to be among the safest critical infrastructures in the country.
Eleven of the Russian reactors are of the RBMK 1000 type, similar to that of the Chernobyl nuclear power plant. The Chernobyl disaster was a nuclear accident that occurred on April 26, 1986 at the Chernobyl nuclear power plant in Ukraine. However, critics of the nuclear industry complain that regulatory bodies are too intertwined with industries themselves to be effective. Nuclear power plants and certain fuel manufacturing facilities must demonstrate that they can defend against a set of adversarial features called the design-based threat.
The most important barrier to the release of radioactivity in the event of an aircraft hitting a nuclear power plant is the containment building and its missile shield. New nuclear power plants shall be designed, located and constructed in a consistent manner with the objective of preventing accidents in commissioning and operation and, in the event of an accident, mitigating potential releases of radionuclides that cause long-term external pollution and preventing early radioactivity radioactive releases or emissions large enough to require long-term protective measures and actions. Nuclear fuel is a strategic resource whose continuous supply must be ensured to avoid plant disruptions. The obligations of Contracting Parties are largely based on the application of the safety principles for nuclear installations contained in the Safety Fundamentals document 'The Safety of Nuclear Installations' (IAEA Safety Series No.
The NNSA Office of Defense and Nuclear Security (DNS) ensures that the security mission is effectively and efficiently executed at all NNSA sites and facilities. If the instability of nuclear material generates unexpected behavior, it can result in an uncontrolled energy excursion.
