  • Nuclear Fuel Market Issues & Insights - multi-client report
    NFMI&I evaluates the worldwide markets for U3O8, UF6 conversion and enrichment services, including demand, the status of major suppliers, as well as projected ranges of and general trends for spot and long-term price movements. NFMI&I addresses the relative sensitivity of the price forecasts to changes in supply-demand balance driven by plausible future scenarios. NFMI&I also analyses the LWR fuel fabrication market, discussing the expected trends in competition and prices for both BWR and PWR segments. The report features concise commentaries on the main issues and conclusions, backed up by appendices compiling the related detailed data and assumptions, NFMI&I presents NAC’s expert opinion of where the markets are heading and why. In late July/early August, NAC issued an addendum to the original report to address the potential impact of Honeywell’s July decision to consider a series of upgrades to its Metropolis Works operations. This decision was made following the recent U.S. Nuclear Regulatory Commission inspection that focused on preparedness for extreme natural disasters such as strong earthquakes and tornados.

  • Fuel Fabrication Industry Competitive Analysis
    This report presents a benchmarking analysis of selected international LWR fuel fabrication vendors. It addresses supply structure and organization, fuel fabrication facility performance in terms of capacities and utilization (load factor), estimates LWR fuel assembly manufacturing costs by fabrication site, including breakdowns to the extent possible by materials, labour, components, processes etc. Full costs and direct fabrication (shop door) costs are presented. These estimates are developed for recent actual shop loads and also for a theoretical average shop load of 80 percent across all facilities, the latter case being developed to provide a like-for-like comparison of the competitiveness of the various fabrication facilities. A description of market prices for LWR fuel fabrication in the U.S. and Europe is included and compared with estimated production costs, in order to assess the approximate financial performance of the fabricator businesses.

  • Analysis of the Russian UF6 Conversion Industry
    The Russian conversion industry was developed under the unique conditions of the Former Soviet Union. Processes were selected and plants were built under very different conditions than existed in the western commercial nuclear fuel industry. This report provides information on production capability, capacity utilization, technologies deployed, plans to modify capacity and the imports and exports of U3O8 and natural UF6.

  • Evaluation of Selected African Uranium Mining Projects
    Detailed cash flows (in constant 2009 U.S. dollars) are presented in this report for 23 projects in Africa based on two assumed average annual selling price scenarios. A net present value is determined for each project based on these two revenue scenarios and estimated life-of-project operating and capital expenditures. In addition, an internal rate of return is calculated for each project based on these two revenue scenarios. Potential risk factors for each project are also identified. The number of potential risk factors varies from project to project depending on each project’s technical parameters, location, stage of development, etc.

  • Survey and Analysis of Transportation Accidents
    NAC compiled a database of over 600 transportation accidents regarding radioactive materials. The database includes accidents on all major continents, every mode of transportation and virtually all forms of radioactive materials. The accidents range in severity from simple spillage to accidents that resulted in significant property damage, personal injury and/or spread of radioactivity with associated evacuation.

  • Nuclear Materials Transportation Situation in Selected Countries
    This report discusses the transportation of nuclear materials[1] to, from and within Australia, China, India, Indonesia, Kazakhstan, Pakistan, Republic of Korea, Taiwan, Thailand and Vietnam. For each country, the report addresses the types of nuclear materials transported to/from and within each country and the associated modes of transportation and international transportation routes. General regulations that govern transportation and the policies in each country that may impact future transportation of nuclear materials are also reviewed

  • Issues Related to the Use of Enriched Uranium Fuel with >5 w/o U235
    This report investigates the issues that would need to be addressed in the event the nuclear industry decided to pursue commercial power reactor fuel enrichments in excess of 5 weight percent (w/o) U235. The report, which concentrates on Light Water Reactors of current and evolutionary designs, addresses issues directly related to the production and use of fuel with greater than 5 w/o U235, including initial transition costs, as well as, issues related to the characteristics of such fuel during and after irradiation.

  • Critical Issues in the Enrichment Market
    Centrifuge enrichment technology is capital intensive. Important determinants of capital costs are the centrifuge machine design and output and whether or not the machine manufacturing supply chain has been operating long enough to be optimized and is producing sufficient volume to achieve economies of scale. These factors provide a relative economic benefit to centrifuge suppliers using technology that has a long operating history and a high volume of centrifuge manufacturing and a disadvantage to a new entrant. Capital costs also are significantly impacted by centrifuge reliability and the lifetime and magnitude of site infrastructure that must be built. These factors also tend to favor the enrichers with established technologies and those facilities with operating sites. These and other related issues are examined in this report.
