Here we present the first report of a carbon-γ-Fe₂O₃ nanoparticle composite of mesoporous carbon, bearing COOH- and phenolic OH- functional groups on its surface, a remarkable and magnetically separable adsorbent, for the radioactive material emitted by the Fukushima Daiichi nuclear power plant accident. Contaminated water and soil at a level of 1,739 Bq kg(-1) ((134)Cs and (137)Cs at 509 Bq kg...

The evaluation on nuclear power plant operational safety performance had great significance on whether the nuclear power plant operated safely or not. Currently the academic literatures on nuclear power plant operational safety performance are rare. Improved Fuzzy evaluation model which introduce confidence level had been used into the evaluation of nuclear power plant operational safety perfor...

This article reviews the process of public response to warnings of an impending nuclear power plant emergency. Significant evidence exists to suggest that people engage in protective action in response to warnings based upon the substance and course through which emergency warning information is disseminated. The three basic components of a warning system are defined, and the elements of public...

Commercial nuclear power plants release gaseous and liquid radiological effluents into the environment as a byproduct of electrical generation. These releases are monitored by federal agencies to ensure compliance of regulatory limits. The U.S. Nuclear Regulatory Commission (NRC) and U.S. Environmental Protection Agency (EPA) offer guidance and make recommendations for domestic power plants eff...

Understanding how to establish standards is essential for risk communication and also provides perspectives for further study. In this paper, the concept of risk analysis as regulatory science for the establishment of standards is demonstrated through examples of standards for evacuation and provisional regulation values in foods and drinking water. Moreover, academic needs for further studies ...

Installed throughout a nuclear power plant, instrumentation and control (I&C) is an essential element in the normal, abnormal and emergency operation of nuclear power plants (International Atomic Energy Agency [IAEA], n.d.). Through their equipment, modules, sensors, and transmitters, I&C systems measure thousands of variables and processes the data to activate pumps, valves, motors, and other ...

Several inquiries have been made to Ocean Networks Canada with regard to the fate and severity of oceanic contamination from the leakage of radioactive material into the Pacific Ocean as a result of the March 2011 damage to the Fukushima Dai-ichi Nuclear Power Plant (FNPP). There are on-going studies and assessments of the impacts on the ocean, primarily by the World Health Organization (1) [2]...
