UxC: Small Modular Reactor Market Outlook
Due to the depletion of the fossil fuels and major concerns about the security of energy in the future to produce fuels, the importance of utilizing the renewable energies is distinguished. Nowadays there has been a growing interest for biofuels. Thus, this paper reveals a general optimization model which enables the selection of preprocessing centers for the biomass, biofuel plants , and warehouses to store the biofuels. The objective of this model is to maximize the total benefits.
Costs of the model consist of setup cost of preprocessing centers, plants and warehouses, transportation costs , production costs , emission cost and the depreciation cost. At first, the deprecation cost of the centers is calculated by means of three methods.

The model chooses the best depreciation method in each period by switching between them. The costs of completing unfinished US nuclear power plants. A cost benefit analysis is performed to assess the costs of completing unfinished nuclear power plants in four regions of the United States of America, north-east, south-east, mid-west and west.
The analysis is in five main sections: the projection of the cost to complete nuclear plants under construction, the forecast of future operations and maintenance costs , the forecast of price of fuels, the evaluation of future electricity demand and capacity growth, and calculation of the financial cost -benefit ratio based on the preceding figures.
It was found that in the north-east, mid-west and west, because the demand for the power will not be made before the year , finishing the units is not the least- cost supply option. The code was then used to examine the dependence of the plant capital costs and the busbar cost of electricity COE on a variety of design parameters type of driver, chamber repetition rate, and net electric power. The base-case plant was a MW e plant containing a reactor vessel driven by an induction linac heavy-ion accelerator, run at 8 Hz with a driver energy of 6. All costs in this paper are given in equivalent dollars.
The COE was 8. The COE and total capital costs for a MW e base plant are nearly independent of the chosen combination of repetition rate and driver energy for a driver operating between 4 and 10 Hz. For comparison, the COE for a coal or future fission plant would be 4. There is a large economy of scale with heavy-ion-driven inertial confinement fusion ICF plants. Electric utility power plant construction costs , 1st Edition. New UDI report combines historical construction costs for more than 1, coal, oil, gas, nuclear and geothermal units that have entered commercial operation since and projected power plant construction costs for about utility-owned generating units scheduled to enter commercial operation during the next 20 years.
Historical construction cost data are also provided for about utility-owned hydroelectric, gas turbine, combined-cycle and diesel units these data are generally for units entering service after Progress report on the investigation of nuclear plant costs. Over the past few years, many studies have been performed in an effort to understand, evaluate, and explain the reasons for the substantial increases in nuclear plant costs , as well as for the divergence between predicted and actual costs.
The future use of nuclear power depends on the ability of the industry to control these costs while maintaining safety. Stone and Webster Engineering Corporation SWEC has responded to this concern by initiating an internal study to evaluate, quantify, and explain the factors influencing this cost growth.
Previously, a conceptual approach was presented in which three explanatory variables or factors were used as surrogates for the many variables that affected plant cost. This paper presents a progress report of that continuing study. Belowground advantages in construction cost facilitate a cryptic plant invasion.
The energetic cost of plant organ construction is a functional trait that is useful for understanding carbon investment during growth e. Despite the enormous importance of roots and rhizomes in acquiring soil resources and responding to global change, construction costs have been studied almost exclusively in leaves. We sought to determine how construction costs of aboveground and belowground organs differed between native and introduced lineages of a geographically widely dispersed wetland plant species Phragmites australis under varying levels of CO2 and N. We grew plants under ambient and elevated atmospheric CO2, as well as under two levels of soil nitrogen.
We determined construction costs for leaves, stems, rhizomes and roots, as well as for whole plants.

Across all treatment conditions, the introduced lineage of Phragmites had a 4. Whole- plant construction costs were also smaller for the introduced lineage, with the largest difference in sample means 3. In having lower rhizome and plant -scale construction costs , the introduced lineage can recoup its investment in tissue construction more quickly, enabling it to generate additional biomass with the same energetic investment. Our results suggest that introduced Phragmites has had an advantageous tissue investment strategy under historic CO2 and N levels, which has facilitated key rhizome processes, such as clonal spread.
We recommend that construction costs for multiple organ types be included in future studies of plant carbon economy, especially those investigating global change. Higher SPK-content fuels could, however, produce desirable fuels: lower density, higher SPK-content fuels may have benefits for. Probabilistic cost estimating of nuclear power plant construction projects. This paper shows how to identify and isolate cost accounts by developing probability trees down to component levels as justified by value and cost uncertainty.
Examples are given of the procedure for assessing uncertainty in all areas contributing to cost : design, factory equipment pricing, and field labor and materials. The method of combining these individual uncertainties is presented so that the cost risk can be developed for components, systems and the total plant construction project.

Formats which enable management to use the probabilistic cost estimate information for business planning and risk control are illustrated. Topics considered include code estimate performance, cost allocation, uncertainty encoding, probabilistic cost distributions, and interpretation. Effective cost control of nuclear power plant construction projects requires insight into areas of greatest cost uncertainty and a knowledge of the factors which can cause costs to vary from the single value estimates. It is concluded that probabilistic cost estimating can provide the necessary assessment of uncertainties both as to the cause and the consequences.

Nuclear Power Plant Operating Cost and Experience Summaries, has been prepared to provide historical operating cost and experience information on U. As discussed in the report, annual data for these two cost categories were obtained from publicly available reports and must be accepted as having different degrees of accuracy and completeness.
Treatment of inconclusive and incomplete data is discussed. As an aid to understanding the fluctuations in the cost histories, operating summaries for each nuclear unit are provided. The intent of these summaries is to identify important operating events; refueling, major maintenance, and other significant outages; operating milestones; and significant licensing or enforcement actions.
Information used in the summaries is condensed from annual operating reports submitted by the licensees, plant histories contained in Nuclear Power Experience, trade press articles, and the Nuclear Regulatory Commission NRC web site www. Evaluating decommissioning costs for nuclear power plants. An overview is presented of the economic aspects of decommissioning of large nuclear power plants in an attempt to put the subject in proper perspective.
This is accomplished by first surveying the work that has been done to date in evaluating the requirements for decommissioning.
A review is presented of the current concepts of decommissioning and a discussion of a few of the uncertainties involved. This study identifies the key factors to be considered in the econmic evaluation of decommissioning alternatives and highlights areas in which further study appears to be desirable.
Evaluation of construction cost of pyro-partitioning plant. This study was conducted to evaluate the construction cost of a pyro-partitioning plant. The block flow diagram and mass balance obtained from our previous experimental data were used to produce a detailed process-flow diagram and to design the plant. On the other hand, the cost of process robots and the equipments for key measurement point KMP is major part in the cost of in-cell equipment.
The two biggest changes in NPP DandD over the last 15 years that are applicable across all countries are: a.
High Burn-up Radioactive Spent Fuel
Equipment and tools used in NPP DandD have evolved to be available on a more industrial basis, although concerning DandD of the main NPP components, such activity typically is very individual and requires one-of equipment to be developed. Regulation of DandD has increased. Earlier regulations were adapting to what emerged from evolving DandD projects. Today regulatory requirements have caught up and have been framed based on the feedback of experience over the last 15 years. In general they impose prescriptive requirements on DandD approaches and execution. In the U.
A newly emerging trend in the U. Regarding access to information that can be meaningful and sufficiently detailed to support an international benchmarking inter-comparison of NPP DandD cost information: - NAC has established good access to detailed information on actual DandD projects at one U. PWR Trojan and one U. BWR Rancho Seco. Additional information sources probably can be accessed with additional investigation.

Accessibility of the information is not yet fully determined. This will need more extensive, face-to-face interaction with the relevant stakeholders. Utilities and cost estimate service providers offer the opportunity to access relevant information. Specific terms and conditions that would apply and the extent of detail that would be. Commercial electric power cost studies. This volume contains the drawings, equipment list and site description. Guidelines for estimating nuclear power plant decommissioning costs. The objectives of the study were: 1 To develop guidelines to facilitate estimating the cost of nuclear power plant decommissioning alternatives on a plant -specific basis and to facilitate comparing estimates made by others.
The guidelines are expressed in a form that could be readily adapted by technical specialists from individual utilities or by other uses. This is accomplished by providing a detailed, systematic breakdown of how decommissioning cost estimates are prepared. This is accomplished by pulling together the experiences and practices of several nuclear utilities and consultants in conducting past decommissioning cost estimates.
Cost estimating relationships for nuclear power plant operationa and maintenance. Revised cost estimating relationships for are presented for estimating annual nonfuel operation and maintenance O and M costs for light-water reactor LWR nuclear power plants , which update guidelines published previously in The purpose of these cost estimating relationships is for use in long range planning and evaluations of the economics of nuclear energy for electric power generation.
