The Future of Nuclear Energy: Facts and Fiction: An update using 2009/2010 Data

An update of our 2009 study, "The Future of Nuclear Energy, Facts and Fiction" using the 2009 and the available 2010 data, including a critical look at the just published 2009 edition of the Red Book, is presented. Since January 2009, eight reactors with a capacity of 4.9 GWe have been connected to the electric grid and four older reactors, with a combined capacity of 2.64 GWe have been terminated. Furthermore, 27 reactor constructions, dominated by China (18) and Russia (4), have been initiated. The nuclear fission produced electric energy in 2009 followed the slow decline, observed since 2007, with a total production of 2560 TWhe, 41 TWhe (1.6%) less than in 2008 and roughly 100 TWhe less than in the record year 2006. The preliminary data from the first 10 months of 2010 in the OECD countries indicate that nuclear power production in North-America remained at the 2009 levels, while one observes a recovery in Europe with an increase of 2.5% and a strong rise of 5% in the OECD Asia-Pacific area compared to the same period in 2009. Worldwide uranium mining has increased during 2009 by about 7000 tons to almost 51000 tons. Still roughly 18000 tons of the 2010 world uranium requirements need to be provided from the civilian and military reserves. Perhaps the most remarkable new data from the just published 2009 edition of the Red Book, are that (1) the best understood RAR (reasonable assured) and IR (inferred) resources, with a price tag of less than 40 US dollars/Kg, have been inconsistently absorbed in the two to three times higher price categories and (2) uranium mining in Kazakhstan is presented with a short lifetime. The presented mining capacity numbers indicate an uranium extraction peak of 28000 tons during the years 2015-2020, from which it will decline quickly to 14000 tons by 2025 and to only 5000-6000 tons by 2035.Comment: 29 pages including 3 pages of reference

Simulation of site-specific irrigation control strategies with sparse input data

Crop and irrigation water use efficiencies may be improved by managing irrigation application timing and volumes using physical and agronomic principles. However, the crop water requirement may be spatially variable due to different soil properties and genetic variations in the crop across the field. Adaptive control strategies can be used to locally control water applications in response to in-field temporal and spatial variability with the aim of maximising both crop development and water use efficiency. A simulation framework ‘VARIwise’ has been created to aid the development, evaluation and management of spatially and temporally varied adaptive irrigation control strategies (McCarthy et al., 2010). VARIwise enables alternative control strategies to be simulated with different crop and environmental conditions and at a range of spatial resolutions. An iterative learning controller and model predictive controller have been implemented in VARIwise to improve the irrigation of cotton. The iterative learning control strategy involves using the soil moisture response to the previous irrigation volume to adjust the applied irrigation volume applied at the next irrigation event. For field implementation this controller has low data requirements as only soil moisture data is required after each irrigation event. In contrast, a model predictive controller has high data requirements as measured soil and plant data are required at a high spatial resolution in a field implementation. Model predictive control involves using a calibrated model to determine the irrigation application and/or timing which results in the highest predicted yield or water use efficiency. The implementation of these strategies is described and a case study is presented to demonstrate the operation of the strategies with various levels of data availability. It is concluded that in situations of sparse data, the iterative learning controller performs significantly better than a model predictive controller

Air pollution and livestock production

The air in a livestock farming environment contains high concentrations of dust particles and gaseous pollutants. The total inhalable dust can enter the nose and mouth during normal breathing and the thoracic dust can reach into the lungs. However, it is the respirable dust particles that can penetrate further into the gas-exchange region, making it the most hazardous dust component. Prolonged exposure to high concentrations of dust particles can lead to respiratory health issues for both livestock and farming staff. Ammonia, an example of a gaseous pollutant, is derived from the decomposition of nitrous compounds. Increased exposure to ammonia may also have an effect on the health of humans and livestock. There are a number of technologies available to ensure exposure to these pollutants is minimised. Through proactive means, (the optimal design and management of livestock buildings) air quality can be improved to reduce the likelihood of risks associated with sub-optimal air quality. Once air problems have taken hold, other reduction methods need to be applied utilising a more reactive approach. A key requirement for the control of concentration and exposure of airborne pollutants to an acceptable level is to be able to conduct real-time measurements of these pollutants. This paper provides a review of airborne pollution including methods to both measure and control the concentration of pollutants in livestock buildings

Assessing Market Expectations on Exchange Rates and Inflation: A Pilot Forecasting System for Bulgaria

Econometric forecasting models typically perform bad in volatile environments as they are often present in economies in transition. Since forecasts of key macroeconomic variable are inevitable as guidelines for economic policy, one might alternatively make attempts at measuring market participants’ expectations or conduct surveys. However, often financial markets are underdeveloped and regular surveys are unavailable in transition countries. In this paper we propose to conduct experimental stock markets to reveal market participants’ expectations. W? present the results fr?m a series of pilot markets conducted in Bulgaria throughout 2002 indicating that the method could be useful especially for transition countries.http://deepblue.lib.umich.edu/bitstream/2027.42/40145/3/wp759.pd

Policies and Measures to Mitigate Potential Environmental Impacts of Cross Border Infrastructure Projects in Asia

While bringing positive impacts and benefits, cross-border infrastructure projects face additional challenges relative to national projects. Moreover, such projects involve a variety of technical, regulatory, institutional, and legal factors, and their obstacles constrain the development of cross-border infrastructure projects. This paper argues that proper technical specifications and well-functioning regulatory, institutional and legislative/legal frameworks with clearer lines of oversight are crucial to getting such projects off the ground in the first place and to ensure that they operate properly and reliably while minimizing their environmental impacts. It is pointed out that many issues in theses areas need to be addressed at the national level. The paper concludes that such domestic efforts, coupled with regional frameworks and arrangements wherever necessary, will promote the further development of cross-border infrastructure projects.asia cross-border infrastructure; environmental impact; asia regional integration

An Economic Perspective on Russia's Accession to the WTO

Russia's application for accession to the WTO is currently in its final phases and may be completed by the end of 2003. In this context, this paper provides some background information on Russia's recent policy and structural reforms, the composition and geographic distribution of trade, tariff rates by commodity groups, and other aspects of trade and domestic policies at issue in the accession process. The accession proce-dure and the current status of the accession process are then discussed. Using a computable general equilibrium (CGE) modeling analysis of China's WTO accession as a prototype, the potential use of CGE model-ing of Russian accession is considered as well as Russia's participation in the Doha Development Round and preferential trading arrangements. It is concluded that Russia may realize significant benefits from WTO accession and from the multilateral trade liberalization to be effected in the Doha Round.http://deepblue.lib.umich.edu/bitstream/2027.42/39857/3/wp472.pd

OLEDs AND E-PAPER. Disruptive Potential for the European Display Industry

DG ENTR and JRC/IPTS of the European Commission have launched a series of studies to analyse prospects of success for European ICT industries with respect to emerging technologies. This report concerns display technologies (Organic Light Emitting Diodes and Electronic Paper - or OLEDs and e-paper for short). It assesses whether these technologies could be disruptive, and how well placed EU firms would be to take advantage of this disruption In general, displays are an increasingly important segment of the ICT sector. Since the 1990s and following the introduction of flat panel displays (FPDs), the global display industry has grown dramatically. The market is now (2009) worth about ¿ 100 billion. Geo-politically, the industry is dominated by Asian suppliers, with European companies relegated to a few vertical niches and parts of the value chain (e.g. research, supply of material and equipment). However, a number of new technologies are entering the market, e.g. OLEDs and electronic paper. Such emerging technologies may provide an opportunity for European enterprises to (re-)enter or strengthen their competitive position. OLEDs are composed of polymers that emit light when a current is passed through them. E-paper, on the other hand, is a portable, reusable storage and display medium, typically thin and flexible. Both OLEDs and e-paper have the potential to disrupt the existing displays market, but it is still too soon to say with certainty whether this will occur and when. Success for OLEDs depends on two key technical advances: first, the operating lifetime, and second, the production process. E-paper has a highly disruptive potential since it opens the door to new applications, largely text-based, not just in ICTs but also in consumer goods, pictures and advertising that could use its key properties. It could also displace display technologies that offer text-reading functions in ICT terminals such as tablet notebooks. There are three discrete segments in the OLED value chain where any discontinuity could offer EU firms the opportunity to play a more significant part in the displays sector: (1) original R&D and IPR for devices and for the manufacturing process and material supply/verification; (2) bulk materials for manufacture and glass; and (3) process equipment:. For the e-paper value chain, we can see that the entry of EU suppliers is perhaps possible across more value chain segments than for OLEDs. Apart from the ones mentioned for OLEDs, there are opportunities to enter into complete devices and content provision. In terms of vertical segments, the point of entry in OLED FPDs for Europe is most likely to be in the mass production of smaller FPDs for mobile handsets. In conclusion, OLEDs and e-paper have the potential to disrupt current displays market and in so doing they may enable EU companies to enter at selected points in the value chain to compete with the Asian ICT industry.JRC.J.4-Information Societ
