TECDOC-1474 Natural Circulation in Water Cooled Nuclear Power Plants
  This report has been prepared within the IAEA’s Coordinated Research Project (CRP) on "Natural Circulation Phenomena, Modelling, and Reliability of Passive Systems that Utilize Natural Circulation". This publication presents extensive information on natural circulation phenomena, models, predictive tools and experiments that currently support design and analyses of natural circulation systems and highlights areas where additional research is needed. It serves both to provide a description of the present state of knowledge on natural circulation in water cooled power plants and to guide the planning and conduct of the CRP to focus the CRP activities on advancing the state of knowledge.
TECDOC-1391 Status of advanced light water reactor designs 2004
  In the field of light water reactors, the last status report published by the IAEA was "Status of Advanced Light Water Cooled Reactor Designs: 1996" (IAEA-TECDOC-968). Since its publication, quite a lot has happened: some designs have been taken into commercial operation, others have achieved significant steps toward becoming commercial products, including certification from regulatory authorities, some are in a design optimization phase to reduce capital costs, development for other designs began after 1996, and a few designs are no longer pursued by their promoters.
TECDOC-1290 Improving Economics and safety of water-Cooled Reactors: Proven Means and New Approaches
  With increasingly liberalized electricity markets around the world, and particularly the success of low-cost combined cycle gas turbines, incentives have increased for identifying means to achieve better NPP economics. The task on “Optimizing Technology, Safety and Economics of Water-Cooled Reactors” was carried out during 1999-2002. The task includes collaboration with eleven industrial organizations and four government agencies as well as the OECD-NEA and the European Commission. Its objective was to emphasize the need, and to identify approaches, for new nuclear plants with water-cooled reactors to achieve competitiveness while maintaining high levels of safety. To achieve the largest possible cost reductions, proven means for reducing costs must be fully utilized, and new approaches (such as improved technologies, risk informed methods for evaluating the safety benefit of design features, and international consensus regarding safety requirements so that standardized designs can be built in several contries without major re-design efforts) should be developed and implemented. Proven means and new approaches are examined using the full breadth and capabilities of the Agency, including expertise in the Nuclear Power Engineering Section and the Planning and Economic Studies Section of the Department of Nuclear Energy, and in the Division of Nuclear Installation Safety of the Department of Nuclear Safety.
TECDOC-1281 Natural circulation data and methods for advanced water cooled nuclear power plant designs
  Proceedings of a TCM on Natural Circulation Data and Methods for Innovative Nuclear Power Plants Design. The objective of this TCM were to assess the current base of experimental data and the applicability of current methodologies for computing natural convection phenomena in innovative reactor design, and to develop perspectives on needed improvements in models and supporting experimental data. This TECDOC provides the papers presented and summarized the discussions. The papers and discussions addressed both evolutionary and innovative designs for light and heavy water reactors.
TECDOC-1264 Reliability Assurance Programme Guidebook for Advanced Light Water Reactors
  This guidebook demonstrates how the designers and operators of future commercial nuclear plants can exploit the risk, reliability and availability engineering methods and techniques developed over the past two decades to augment existing design and operational nuclear plant decision-making capabilities.
TECDOC-1245 Performance of Operating and Advanced LWR Designs
  Proceedings of a TCM hosted by E.ON Energie AG (Munich) in October 2000. The TCM provided a forum for information exchange on design features and technologies incorporated into LWR plants commissioned within about the last 15-20 years, and into evolutionary LWR designs still under development, for achieving performance improvements with due regard to stringent safety requirements and objectives. It also addressed on-going technology development expected to achieve further improvements and/or significant cost reductions.
TECDOC-1203 Thermohydraulic Relationships for Advanced Water Cooled Reactors
  This report has been prepared within the IAEA’s Coordinated Research Project (CRP) on "Thermohydraulic Relationships for Advanced Water Cooled Reactors" which was started in 1995 with the overall goal to promote information exchange and co-operation in establishing a consistent set of thermohydraulic relationships which are appropriate for use in analyzing the performance and safety of advanced water cooled reactors. The CRP participants collaborated to examine the requirements for thermohydraulic relationships and to conduct research and to review experimental data for critical heat flux (CHF), post CHF heat transfer and pressure drop. These relationships are presented in the TECDOC.
