AbstractAbstract
[en] This article presents the different notions of cost concerning electricity production. Costs are in fact complex economic data that are designed in the view of the type of decision they will help to settle. Electricity production industry is facing new challenges with the opening of national markets and the stiffening of competition, so decisions about the economic policy of major electricity producers have to be taken carefully and managers require real and valid costs to do so.

AbstractAbstract
[en] This paper describes a micro-economic, cost-engineering model of a centralized (Generic Interim Storage Facility - GISF) facility to monitor LWR irradiated fuel with particular attention to scale economies (e.g., to compare the likely costs at a power plant site or at regional, national and international facilities). This paper is based on the cost estimates of the Private Fuel Services Facility (PFSF) on the Skull Valley Band of Goshute Indians' Reservation in Utah, licensed by the US NRC in 2006 to centralize storage of 40.000 metric tons of heavy metal (MTHM) for 20 to 40 years. Assuming movement of the 40.000 MTHM every 40 years to a new facility, the levelized costs are 144 dollars/kg without high security and physical protection, and 208 dollars/kg with high security through 2111 (assuming disposal within a century), or about 0.50 dollars/MWh to 0.75 dollars/MWh depending on the burnup and thermal efficiency of the nuclear power plant. This cost estimate is generalized to explore scale economies for facilities with and without high security and physical protection. There are declining levelized costs with increasing size to 120.000 MTHM without high security, and to 500.000 MTHM with high security, i.e., the higher the level of security, the stronger the economies of scale.

AbstractAbstract
[en] Several advanced power plant concepts are currently under development. These include the Modular High Temperature Gas Cooled Reactors, the Advanced Liquid Metal Reactor and the Advanced Light Water Reactors. One measure of the attractiveness of a new concept is its cost. Invariably, the cost of a new type of power plant will be compared with other alternative forms of electrical generation. This report provides a common starting point, whereby the cost estimates for the various power plants to be considered are developed with common assumptions and ground rules. Comparisons can then be made on a consistent basis. This is the second update of these cost estimate guidelines. Changes have been made to make the guidelines more current (January 1, 1992) and in response to suggestions made as a result of the use of the previous report. The principal changes are that the reference site has been changed from a generic Northeast (Middletown) site to a more central site (EPRI's East/West Central site) and that reference bulk commodity prices and labor productivity rates have been added. This report is designed to provide a framework for the preparation and reporting of costs. The cost estimates will consist of the overnight construction cost, the total plant capital cost, the operation and maintenance costs, the fuel costs, decommissioning costs and the power production or busbar generation cost

AbstractAbstract
[en] This paper focuses on one of the important technology issues facing the gamma processing industry today: that of strategically planning for extending the useful life of a production irradiator. Production irradiator owners are typically faced with the difficult question of whether or not to significantly reinvest in their facilities after 15-20 years of service. At this point in time the irradiator has likely provided many years of safe, reliable service and has paid for itself many times over. As the equipment ages, it may become less reliable, due to wear and maintenance practices, and more costly to operate. The cost of refurbishing the equipment may be significant and the downtime required to complete the refurbishment is also likely to be a challenge. This makes it essential to present a clear and rational justification for reinvesting in the facility. There has been a growing trend in recent years for irradiator owners to refurbish or upgrade their facilities. This trend is driven by the need to keep the facilities operating efficiently and safely as well as by the desire to take advantage of advancements that have occurred in the technology over the years. These advancements can enhance equipment efficiency, improve operational effectiveness and maintain or exceed quality assurance requirements. This paper illustrates the value of reinvesting in irradiator facilities, and highlights the significant benefits derived

AbstractAbstract
[en] Mechanical Unit under Engineering Department is responsible in operation and maintenance of building mechanical system and also government vehicles in Malaysian Nuclear Agency. Mechanical Unit manages about 15 periodic maintenance contracts and at least 10 repairs and upgrading works of building mechanical system a year. Among the main building mechanical system are air conditioning and ventilation systems, air compressors, fire protection systems, elevators, overhead crane and LPG system. In 2015, the maintenance of this mechanical system costs almost RM2.0 million a year. However, several measures have been taken in order to reduce this maintenance cost to RM1.5 million in 2020. This paper will describe the efforts have been taken to reduce maintenance cost of building mechanical system. With the savings achieved, this surplus operating expenditure has been used for other uses which can benefit the Malaysian Government, especially the Malaysian Nuclear Agency. (author)

AbstractAbstract
[en] The French Court of Auditors estimates at 60 euros/MWh the cost of operating reactors. This cost includes a fair remuneration of the initial investment. Cash costs represent future charges concerning maintenance, exploitation and upgrading or safety investments for a nuclear reactor. Cash costs are about 36 euros/MWh. The cost of the Flamanville EPR has been reassessed at 12.7 billions euros which is almost the cost of the pair of EPR built at Taishan (in China). Concerning the EPR-2 reactor, the cost of the construction of 3 pairs of reactors is estimated to be 51.7 billions euros. System costs are complete costs of power systems for instance they include the cost of flexibility tools that are needed to compensate the intermittent power production of renewable energies. The social complete cost (or full cost) adds to the system costs the costs of accidents, wastes, sanitary impacts... Nuclear power appears to have one of the lowest full cost of all energies. (A.C.)

AbstractAbstract
[en] A first assessment of the technical and economical consequences of liquid nitrogen cooling of new superconductors is given. For the investigation the applications of superconductivity are classified in two categories: First, systems where superconductors are practically indispensable for achieving the system's objectives; second, superconductor applications in competition with highly developed conventional technologies. Further development of those superconducting systems in the first category for which the cost of cryogenic equipment is a smaller fraction of the total system cost (e.g. fusion reactor or MHD generator) will hardly be affected. However, for systems like particle accelerators, research magnets, and NMR spectroscopy and imaging systems, the cryogenic equipment expenditures are significant and LN2 cooling leads here to a reduction of investment and operating costs, to simplified handling and maintenance, to better reliability and availability, and will thereby improve the acceptance and further spread of these systems. In the second category each application of superconductivity has to be compared with its conventional counterpart, separately. Here, electonic components, power switches, resistive current limiters, and especially the power transmission cables are those applications which look most promising. For magnet applications the main advantageous arguments are less the cost saving aspect but more the higher reliability, simplicity, N2-availability, and ease of handling. (orig.)

Es wird eine erste Abschaetzung der technischen und oekonomischen Konsequenzen der Stickstoff-Kuehlung von neuen Supraleitern gegeben. Fuer die Untersuchung werden die Supraleitungsanwendungen in zwei Kategorien eingeteilt: Erstens, Systeme fuer die zum Erreichen der Ziele Supraleiter praktisch unabdingbar sind; zweitens, Supraleitungsanwendungen im Wettbewerb mit hochentwickelter konventioneller Technologie. Die weitere Entwicklung jener Systeme der ersten Kategorie, fuer die die Kosten der kryogenen Ausruestung ein kleinerer Bruchteil der Gesamtkosten sind (z.B. Fusionsreaktor oder MHD-Generator), wird kaum beeinflusst. Fuer Systeme wie Teilchenbeschleuniger, Forschungsmagnete sowie Kernspin-Spektroskopie- und Kernspin-Tomografie-Systeme sind jedoch die Kosten der Kryo-Ausruestung von Bedeutung, und LN2-Kuehlung fuehrt hier zu einer Verringerung der Investitions- und Betriebskosten, zu vereinfachter Handhabung und Wartung, zu erhoehter Zuverlaessigkeit und Verfuegbarkeit und wird damit die Akzeptanz und weitere Verbreitung dieser Systeme foerdern. In der zweiten Kategorie muss jede Anwendung der Supraleistung separat mit ihrem konventionellen Gegenstueck verglichen werden. Vielversprechend erscheinen hier elektronische Komponenten, Leistungsschalter, resistive Strombegrenzer und vor allem elektrische Energieuebertragung. Bei Magnetanwendungen liegen die Hauptvorteile weniger bei der Kostenersparnis als vielmehr bei hoeherer Zuverlaessigkeit, Einfachheit, N2-Verfuegbarkeit und leichter Handhabung. (orig.)Source

AbstractAbstract
[en] The nuclear industry has higher costs for personnel, equipment, construction, and engineering than conventional industry, which means that cost estimation procedures may need adjustment. The authors account for the special technical and labor requirements of the nuclear industry in making adjustments to equipment and installation cost estimations. Using illustrative examples, they show that conventional methods of preliminary cost estimation are flexible enough for application to emerging industries if their cost structure is similar to that of the process industries. If not, modifications can provide enough engineering and cost data for a statistical analysis. 9 references, 14 figures, 4 tables
