Abstract The influence of different power augmentation techniques used in gas turbines on the performance of simple cycle type power plants is assessed in this work. A computational model and tool realistically describing the performance of a typical simple cycle type power plant at design and off-design point conditions is initially developed. This tool is complemented with different models of power augmentation technologies. Finally, the whole model including both power plant and power augmentation techniques is used to analyze a case study involving a particular power plant in Peru. The results from the simulations of the specific power plant indicate that power output can be increased through all the evaluated power augmentation technologies. These results show indeed that technologies based on absorption refrigeration systems produce the largest gains in terms of power output (7.1%) and thermal efficiency (0.7%). Such results confirm the suitability of these systems for simple cycle type power plant configurations operating under hot and humid operating conditions as those accounted for here. From an economic perspective, considering the net present value as the key parameter defining the feasibility of a project in this category, power augmentation techniques based on absorption cooling systems result also the most suitable ones for the studied power plant. Power augmentation techniques environmental implications are also quantified in terms of CO2 emissions.

Environmental Context.Industrial metal production, thermoelectric power plants, and similar technologies can release a large amount of particles (with sizes up to the millimetre scale) of heavy metals into the local surrounds. Up to 10% of these particles are strongly magnetic and easily detectable above the background magnetism. A map of the regional magnetic signals, which would be relatively simple and cheap to produce, provides a guide to pollution ‘hotspots’. But it’s not that simple: The authors integrate chemistry, microscopy, and magnetism studies of single particles of sediments from the Danube River to show rock magnetic parameters established for natural rocks cannot be directly used on environmental man-made particles. Abstract.The presence of significant amounts of strongly magnetic phases in anthropogenic particulate industrial emissions allows the use of magnetic methods for fast and cheap detection of environmental pollution. The aim of our study is to check the validity of some of the constitutive magnetic parameters and their ratios used for estimation of grain sizes and distance from the pollution source. The results from our integrated magnetic, microscopic, and microchemical study on large, single, anthropogenic particles show that classical rock magnetic parameters (Mrs/Mr, Bcr/Bc) for mineral magnetic characterization cannot be directly applied to the anthropogenic phases. This results from their inhomogeneous composition, often with dendritic exsolution of iron oxides within an aluminosilicate matrix.

Cooperative Research And Development

InThe last days of its life, the 85th Congress gave its approval to the joint United States-Euratom research and power reactor program, in the legislation known as the Euratom Cooperation Act of 1958. This law provides that the United States will assist the European Atomic Community in attaining its goal of a total installed capacity of approximately 1 million kilowatts of electricity by December 31, 1963, by bringing into operation power plants using nuclear reactors. In addition, the legislation authorizes an initial appropriation of $3,000,000 for a cooperative research and development program, and provides for sale or lease to the Community of fissionable uranium 235 and one kilogram of plutonium. This law was implemented by the agreement for cooperation containing provisions for financing, which entered into force on February 18, 1959. This legislation marked the high point of American collaboration with the latest institution of the European Community. As such, it is a logical point of departure for recapitulating the current status of that Community and its relations with the United States.

Main goal of the project within the European Community 5th Framework Program was in a preparation, evaluation and mutual agreement of a “Unified Procedure for Lifetime Assessment of Components and Piping in WWER Type Nuclear Power Plants”. This procedure should be based on former Soviet rules and codes, as WWER components were designed and manufactured in accordance with requirements of these codes and from prescribed materials. Then, critical analysis of possible application of some approaches used in PWR type components was performed and such approaches have been incorporated into the prepared procedure as much as possible with the aim of a harmonization of WWER and PWR Codes and procedures. Preparation of a Unified Procedure for WWERs operating in Finland, Czech Republic, Slovak Republic, Hungary and Bulgaria will increase the level of lifetime/integrity evaluation in these countries and will help to elaborate a unified approach and fully comparable results between individual plants and countries. Then, harmonization with PWR codes allows to obtain results that will be comparable, reliable and more sophisticated as similar approaches will be used in both types of reactors. The paper described main principles, approaches and achievements of the “Unified Procedure...”.

Metallic Contamination

This study introduces a spatiotemporal evaluation of the metallic contamination with three trace metals (mercury, lead, and cadmium) in the muscles of three fish species (Lepomis macrochirus, Barbus callensis, and Barbus nasus), of which the samples were taken from three stations in the Moulouya River: the confluence of the Moulouya River and the Sebra River (station 1), the neighbourhood of the farms in the region of Aklim downstream from confluence of Lakhmis river (station 2), and the level of ancient bridge of Ras El Ma-Moulouya (station 3), during the period from July 2017 to May 2018. The results have allowed us to highlight rather high contents of lead and mercury in the fish muscles, mainly in station 1, which receives domestic and industrial discharges. The contents of cadmium in all fish species in different stations are very low. Moreover, all concentrations assessed in different fish species do not exceed the maximum limit recommended by European Community (EC) Commission Regulation No. 1881/2006.
