Nuclear power plant safety performance indicators are developed "by nuclear operating organisations to monitor their own performance and progress, to set their own challenging goals for improvement, and to gain additional perspective on performance relative to that of other plants". In addition, performance indicators are widely used by regulatory authorities although the use is not harmonised....

The idea of a circular economy (CE), which differs from traditional linear economy with a high consumption of natural resources and pollution, has captured much interest and attention. This paper uses a CE system of coal power and cement in Kongtong District, Pingliang City, Gansu Province, China as a case study to analyze the comprehensive effects of CE paradigm. Our simulation results, based ...

Since the 19th century, with industrial and urban development and the consequent increase in emissions from industrial activities and vehicular emissions have been observed air pollution effects on living organisms. Thus, since the beginning of the twentieth century, have been carried out several studies that include studies of the effect of pollution on plants (Chies,1983). Some features obser...

Three alternative condensing mode power and combined heat and power (CHP) waste-to-energy concepts were compared in terms of their impacts on the greenhouse gas (GHG) emissions from a heat and power generation system. The concepts included (i) grate, (ii) bubbling fluidised bed (BFB) and (iii) circulating fluidised bed (CFB) combustion of waste. The BFB and CFB take advantage of advanced combus...

About 33% of the thermal energy produced in nuclear reactions is converted into electricity. The remaining 67 released, for example, sea, etc., as waste heat. Therefore, heat recovery and its use power plants (NPPs) are important increasing generation efficiency. this paper, an absorption refrigerator using reactor cooling water (waste heat) seawater sources was used to generate cold heat, wher...

The penetration of renewable sources in the national energy mix is necessary for most of the industrialised countries in order to comply with the ever-challenging constraints imposed by environmental impact reduction policies. However, a big family of renewable sources have the peculiarity of being non-programmable, that is very variable throughout hours and seasons. While the traditional elect...

In the endeavour of avoiding presence of biodegradable waste in landfills and increasing recycling, mechanical-biological treatment (MBT) plants have seen a significant increase in number and capacity in the last two decades. The aim of these plants is separating and stabilizing the quickly biodegradable fraction of the waste as well as recovering recyclables from mixed waste streams. In this s...

Nowadays, energy plays an important role in the economic and community development of country. Consequently, performance analysis of energy systems is one of the effective methods being used to prevent waste of energy resources. Among the different power generation technologies, steam power plants make a significant contribution to power generation in Iran, with a share of 47 % of electricity g...
