nuclear power reactors are, in nature nonlinear and time varying. these characteristics must be considered, if large power variations occur in their working regime. in this paper a robust optimal gain scheduling controller for regulating the power of a nuclear reactor has been designed and simulated. the proposed controller is capable of regulating power levels in a wide power range (10% to 100...

A car-borne survey for dose rate in air was carried out in March and April 2011 along an expressway passing northwest of the Fukushima Dai-ichi Nuclear Power Station which released radionuclides starting after the Great East Japan Earthquake on March 11, 2011, and in an area closer to the Fukushima NPS which is known to have been strongly affected. Dose rates along the expressway, i.e. relative...

Artificial intelligence is the science of automating intelligent behaviours currently achievable by humans. Power system has grown tremendously over a few decades. As the size and complexity of the power system consisting of generators, transmission lines, power transformers, distribution transformers etc. increases the possibility of inviting faults. The acquisition of data, the processing of ...

Dear Editor-in-Chief Nuclear energy is economically feasible. Therefore, nuclear power plants produce about 16% of the world’s electricity nowadays. Calder Hall in the United Kingdom is the world’s first commercial nuclear power station in 1956 (1). In the United States, Shippingport was first operated since 1957. However, the accident like Three Mile Island and Chernobyl disaster had awakened ...

Various radionuclides including fission products and heavy nuclides were released into the environment during Fukushima Daiichi Nuclear Power Station (FDNPS) accident. The dissolution followed by migration of deposited Cs, Sr U on soils could take place to local environment. Therefore, it is necessary determine sorption-desorption coefficients in soil-water system around FDNPS from a viewpoint....
