In this paper the Analytic Network Process (ANP) is applied to the selection of photovoltaic (PV) solar power projects. These projects follow a long management and execution process from plant site selection to plant start-up. As a consequence, there are many risks of time delays and even of project stoppage. In the case study presented in this paper a top manager of an important Spanish compan...

In recent years, subbituminous coal from the Powder River Basin and lignites from Texas and North Dakota have captured an increasing share of the power generation market involving pulverized coal-fired power plants. However, these coals contain relatively large amounts of moisture, which affect unit performance, stack emissions and plant maintenance costs. The moisture also results in fuel hand...

The Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWGNPPCI) of IAEA has been active in providing guidance for the I&C field in the form of technical documents and reports. This year the writing of a new TECDOC to address the challenges in the implementing and licensing digital I&C in nuclear power plants was initiated. This paper reports on discussions within this ...

We present the status of the Angra Neutrino project, describing the development of an antineutrino detector aimed to monitor nuclear reactor activity. The experiment will take place at the Brazilian nuclear power plant located in Angra dos Reis. The Angra II reactor, with 4GW of thermal power, will be used as a source of antineutrinos. We expect to observe about one thousand events per day with...

KNICS (Korea Nuclear Instrumentation and Control System) is a national promoted project to develop a safety-critical level embedded system for nuclear plant protection system. PLC(Programmable Logic Controller) is a typical embedded system to instrument and control plant system, and KNICS has been developing a PLC for controlling a reactor of nuclear power plant system. The PLC micro-kernel is ...

The efficiency and output power of gas turbine power plants are heavily affected by ambient air temperature. To compensate this defect, some cooling technologies and technics are applied. In this paper, the effect of applying an absorption chiller by recovering waste heat from gas turbine flue gas has been investigated. For this purpose, the behavior of a GE-F5 gas turbine was modeled by coding...

A Bulgarian project at Maritsa East power station demonstrated the proper transformation of air pollutants (SOx and NOx) into nitrogen fertilizer. Although this technology has not been put into practice in Bulgaria, it seems feasible on an industrial scale and so it may help to ease Portugal’s reliance on imports of nitrogen fertilizer and thereby contain the outfl ow of Portuguese funds. The d...

Alpine rivers have been channelized by significant river training works in the past two centuries and are now disconnected from their natural environment. In addition, their flow regime is often affected by hydropower plant operation. Also the risk of flood damages is increasing continuously due to urbanization requiring additional flood protection measures. Nevertheless, such trained rivers st...
