Implementation of radiation protection and pollution control procedures. Compliance with approved operating and maintenance procedures. Implementation of training and qualification programs in radiation protection and conducting refresher courses to impart the concept and awareness of ALARA. Recognizing the seriousness of the accident at the Fukushima Daiichi nuclear power plant, where all power sources in Units 1, 2, 3 and 4 failed due to the tsunami, electric power companies in Japan have committed to strengthening safety assurance measures at their nuclear power plants by focusing on measures against tsunami.
The main objective of nuclear power plant regulations is to ensure that there are no failures, but all possibilities must be considered. If faults occur, they must be properly monitored. If those protections fail, systems must be in place to limit the consequences. Although the construction and operation of these facilities are closely monitored and regulated by the Nuclear Regulatory Commission (NRC), accidents are possible.
The protection of critical infrastructure, such as nuclear power plants, is a requirement and a necessity for chemical facilities, the operation of nuclear reactors and many other utility facilities. It should be noted that a commercial-type power reactor simply cannot, under any circumstances, explode like a nuclear bomb: fuel is not enriched more than about 5% and much greater enrichment is needed for explosives. The exercise covered 147 nuclear plants in 15 EU countries, including Lithuania, with only plants decommissioned, plus 15 reactors in Ukraine and five in Switzerland. Knowledge management policies and practices should help create a supportive organizational culture that recognizes the value of nuclear knowledge and promotes effective processes to maintain it.
For low-lying sites, civil engineering and other measures are usually taken to make nuclear plants resistant to flooding. It shows that many residents are experiencing increasing frustration and instability due to the nuclear crisis and the inability to return to the lives they lived before the disaster. Nuclear reactor accidents have long been claimed to be the epitome of low-probability but high-consequence risks. Therefore, even if the containment structure surrounding all modern nuclear power plants were to break, as was the case with one of Fukushima's reactors, it is still very effective in preventing the escape of most of the radioactivity.
The IAEA defines nuclear safety as the prevention and detection and response to theft, sabotage, unauthorized access, illegal transfer or other malicious acts involving nuclear materials, other radioactive substances or their associated facilities. Two government advisers have said that Japan's nuclear reactor safety review following the Fukushima disaster is based on erroneous criteria and that many people involved have conflicts of interest. Various earthquake safety measures are taken at all stages of nuclear power plant design and construction. Katsuhiko Ishibashi, professor of seismology at Kobe University, has said that the history of nuclear accidents in Japan is due to overconfidence in the plant's engineering.
The nuclear fuel cycle includes the extraction and enrichment of radioactive minerals, the production of nuclear fuels, the transportation and use of fuel in the operation of nuclear power plants, the reprocessing of spent fuel to recover reusable materials for more fuel, and the nuclear waste storage.

Nuclear DKM practices can enhance and support traditional business functions and objectives, such as human resource management, training, planning, operations, maintenance, and more. .
