Повний текст джерелаAfrican states are interested in the development of nuclear power (also referred to as atomic power) for the generation of electricity and desalination. These include Algeria, Egypt, Ghana, Kenya, Morocco, Namibia, Niger, Nigeria, Tunisia, South Africa, and Uganda. The nuclear governance in South Africa has adopted principles into its legal system which require it to comply with the objectives of numerous resolutions, conventions, treaties, bilateral and multilateral agreements. Therefore, there is an obligation upon the government through ‘reasonable legislative and other measures’ to manage nuclear matters, such as nuclear accidents, in a manner that protects the general public, atomic industry workers as well as prevents the pollution of the surrounding environment. It has been seven years since the Fukushima Daiichi Nuclear Power Plant Accident that occurred in Japan on 11 March 2011, when considerable amounts of radioactive material from the damaged plant released into the environment. Health hazards, associated with exposure to low levels of ionising radiation, are a significant concern following such an accident. A nuclear disaster can potentially violate not only the right to health of workers, but that of residents and evacuees alike, particularly pregnant women, older persons, and children. Regional and international human rights conventions impose obligations on state parties to “take whatever steps necessary to ensure that the right to the highest attainable standard of health is enjoyed by all as soon as possible”. In most cases, when a nuclear accident occurs, workers within the nuclear plant are expected to mitigate emergencies. The danger of this expectation is that it could violate their fundamental human rights.

Повний текст джерелаThe increased demand for electricity has persuaded a number of countries world-wide to re-evaluate their strategies on energy production. These strategies largely focus on expanding the power generation capacity and adjustment of the amount of energy generated from various sources, in the light of global climate change, security of energy supply and fossil fuel price volatility (OECD report, 2010). In the United States of America (USA), for example, according to Ansolabehere & Konisky (2009), a projection of 40% rise in electricity demand is forecast over the next three decades presenting a need for diversifying the energy mix and expanding power generation capacity. The need for expanding energy supply is increasingly becoming more pronounced in a number of developing countries as well. The demand for energy warrants generation of energy from a variety of sources: coal-fired power plants, gas turbines, wind farms and nuclear power facilities. In order to transmit electricity efficiently these facilities need to be located near residential centres. The challenges associated with the construction of such centres are multi-fold. The option of nuclear power generation is a very divisive issue with as many opponents as supporters, and it has certainly been put back on the agenda in many countries including China, India and Russia, with over 250 nuclear projects in the pipeline globally. The construction of nuclear power plants is often masked with opposition from the public resulting in huge delays in completing the projects yet, nuclear energy is considered as one of the most comprehensive and cost-effective generating options which has the potential to reduce carbon dioxide emissions, meet the ever-increasing demand for electricity as well as making a crucial contribution to energy independence and security of supply.
Kanike, Vanaja. "“Acid-spike” effect in spurs/tracks of the low/high linear energy transfer radiolysis of water : potential implications for radiobiology and nuclear industry." Mémoire, Université de Sherbrooke, 2016. http://hdl.handle.net/11143/9711.
Повний текст джерелаAbstract : Hydronium ions (H3O+) are formed within spurs or tracks of the low or high linear energy transfer (LET) radiolysis of pure, deaerated water at early times. The in situ radiolytic formation of H3O+ renders the spur and track regions temporarily more acid than the surrounding medium. Although experimental evidence for an acidic spur has already been reported, there is only fragmentary information on its magnitude and time dependence. In this work, spur or track H3O+ concentrations and the corresponding pH values are obtained from our calculated yields of H3O+ as a function of time, using Monte Carlo track chemistry simulations. We selected four impacting ions and we used two different spur and track models: 1) an isolated “spherical” spur model characteristic of low-LET radiation and 2) an axially homogeneous “cylindrical” track model for high-LET radiation. Very good agreement was found between our calculated time evolution of G(H3O+) in the radiolysis of pure, deaerated water by 300-MeV incident protons (which mimic 60Co gamma/fast electron irradiation) and the available experimental data at 25 °C. For all cases studied, an abrupt transient acid pH effect, which we call an “acid spike”, is observed during and shortly after the initial energy release. This acid-spike effect is virtually unexplored in water or in a cellular environment subject to the action of ionizing radiation, especially high-LET radiation. In this regard, this work raises a number of questions about the potential implications of this effect for radiobiology, some of which are briefly evoked. Our calculations were then extended to examine the effect of temperature from 25 to 350 °C on the yield of H3O+ ions that are formed in spurs of the low-LET radiolysis of water. The results showed an increasingly acidic spike response at higher temperatures. As many in-core processes in a water-cooled nuclear reactor critically depend on pH, the question here is whether these variations in acidity, even highly localized and transitory, contribute to material corrosion and damage.

Повний текст джерелаENGLISH ABSTRACT: The International Energy Agency will for the first time in its 32 years history urge governments to speed up the construction of nuclear power plants. According to Fatih Birol, lEA chief economist, "the decision almost needs to be made tomorrow if we are going to act before we reach a point of no return in climate and security of supply." Nuclear energy, through the conversion and enrichment of uranium oxide, is one of the energy sources with the potential to make an immediate and substantial difference in the emission of greenhouse gasses. Uranium Oxide currently provides a cost effective and sustainable source of clean energy through nuclear power generation, directly comparable in price to gas and coal. With the growth of the world economy, comes a requirement for more energy. This can only be sustained through a number of sources, of which uranium and renewable sources of energy i.e. wind power generation, is part of. The supply of uranium oxide from production to conversion is key to the success of the uranium industry. The high energy potential of relative small quantities of uranium makes rt ideal to transport as the cost and handling is reduced. The transportation of uranium oxide is continuously increasing in complexity. This combined with a high price scenario, increased demand and supply shortages increases the risk associated with denial and delays of shipments.
AFRIKAANSE OPSOMMING: Die Internasionale Energie Agentskap gaan vir die eerste keer in die organisasie se 32-jaar geskiedenis' regerings aanspoor om die konstruksie van kemkragsentrales te bespoedig. Volgens Fatih Birol, IEA se hoof-ekonoom, "moet die besluit amper more geneem word as ons gaan reageer voor ons 'n punt van geen omdraai bereik het ten opsigte van die klimaat en sekuriteit van aanbod." Kernkrag, deur die omskakeling en verryking van uraanoksied, is een van die energie bronne met die potensiaal om 'n onmiddelike en substansiele verskil in die vrylating van groenhuis-gasse te maak. Uraanoksied verskaf huidiglik 'n koste effektiewe en volhoudbare bron van skoon energie deur kernkrag opwekking, direk vergelykbaar met steenkool en gas. Met die groei in die wereld ekonomie, kom die vraag na meer energie. Dit kan slegs volhoudbaar wees uit 'n aantal bronne waarvan uraan en hernubare bronne soos windkrag-opwekking, deel is. Die verskaffing van uraanoksied van produksie tot verryking is die sleutel tot die sukses van die uraan industrie. Die hoe energie potensiaal van relatiewe klein hoeveelhede uraan, maak dit geskik vir vervoer omdat die koste van vervoer en hantering verminder word. Die transportering van uraan oksied is voortdurend besig om in kompleksiteit toe te neem. Gekombineerd met 'n hoe prys senario, verhoogde vraag na en aanbodtekorte, verhoog die risiko verbind met wyering en vertragings in verskeping.

Повний текст джерелаThere is a South African Government initiative to use State-owned Enterprises (SOE’s) to roll out a programme for the development and stimulation of local small businesses in South Africa. The state has requested SOE’s to set targets on a voluntary basis to increase trade with small businesses, with the purpose of developing small enterprises to eventually enhance skills transfer, training and employment. However, when large customers such as Eskom Nuclear Generation require ISO certification as a prerequisite for a supplier to provide goods and/or services to them, most small businesses are unable to comply. The requirement of ISO9000 compliance inhibits the ability of most small businesses to compete with their larger counterparts. Small businesses constitute as much as 90% of most world economies. They have many advantages to offer customers, such as a high level of flexibility, innovation and responsiveness to customer needs. These attributes can introduce healthy competition to the supply chain. Small businesses, by their very nature experience more risks, such as a higher vulnerability to volatile market forces and skills loss. In addition, they are generally less specialised. They are under continuous competitive pressure, and are generally not able to provide assurance of a sustainable product over a longer period. Although there is an imperative to develop and use small suppliers, they introduce higher risk to the supply chain. The primary research objective of this dissertation is to develop a robust model to identify risks inherent to small businesses, and to propose measures to mitigate such risks. A classification of problems with small suppliers that have occurred at Koeberg Nuclear Power Station over a period of 3 years (from June 2005 to May 2008), will form the basis of the research methodology. The anticipated findings of the research include the following. _ Several common critical issues of failure will be identified in the internal processes of small suppliers, with variations between types of suppliers, which will indicate which elements within the context of ISO9000 can be applied to address shortcoming in the suppliers’ processes. _ A matrix will be compiled from this by which the customer can identify the type of supplier, the types of risks inherent to that supplier, and which elements of ISO9000 the customer should insist upon to be adopted into an elementary quality management system of that small supplier. This should be executed as part of a larger supplier development programme.

Повний текст джерелаThis doctoral dissertation describes the running of a high-risk process industry,nuclear power plants, and the operators’ autonomy to apply technical procedures.The chosen procedures must fit the "real-life" situations, which are always new, andultimately unique. Nuclear power technology is so complex that ambiguous situations often arise. The operators have to make technical decisions that encompassall the demanding issues of high-risk industries : nuclear safety, plant availabilityand generation output, workers’ safety, environmental protection, etc.Operating a nuclear power plant thus involves trade-offs between theoretically compatible concerns that in practice are incompatible or difficult to reconcile.Each option in the actual decision will have advantages for certain criteria anddisadvantages for others. Deciding thus always means forgoing something, andtechnical decision-making in high-risk organizations forces the field workers totake professional and personal risks. The dissertation thus examines the factors explaining why operators are still interested in getting involved in the action.Self-interest and cultural theories cannot explain all the cases encountered in thefield (workers with high commitment but paradoxically little interest in career advancement, strong differences between individuals in a supposedly homogenoussocio-professional groups, etc.). The research focuses on social recognition andgift/countergift theories as the primary explanation for motivation and cooperation at work

Повний текст джерелаThe thesis studies the evolution of the power generation system of electricity, during the Franco’s Regime (1940-1975). In this period, it began the construction of a unified system of exploitation, where the power installed was moved from 1.731Mw to 25.467Mw. The system was called "self regulation", allowing the coexistence of private electric companies, grouped around UNESA and the INI in its electrical aspect. However, the decisions and the power policy, and later on the energy, was directly influenced by the government. It discusses the importance of the primary energy sources (hydro, coal, fuel oil, natural gas, nuclear) in electric power generation. However, it is not intended to illustrate a comprenhensive explanation of the environmental impact and its consequences and effects long term. To sum up, all this takes place in the relevant historical context in a technical and economical perspective.
