Analysis of Differences in Fuel Safety Criteria for WWER and Western PWR Nuclear Power Plants


Book Description

This report captures the common features and differences between Western PWR and WWER fuel, and may serve as a general basis for the sefety evaluation of these fuels. Therefore, it should be very beneficial for PWR and WWER licensing activities, as it focuses on the issues of importance for the review of fuel safety cases.

Thermal and Reliability Criteria for Nuclear Fuel Safety


Book Description

The book covers basic approaches to the nuclear fuel state of energy reactors in the last stages of the nuclear fuel cycle, these have been developed by the authors based on Ukrainian Nuclear Power Plant (NPP) operational experience. The book starts by looking at the physical safety basis of water-water energetic reactor (WWER) nuclear fuel. It goes on to discuss modern approaches to the heat exchange modelling in nuclear power plant equipment. Next, the safety criteria when making a decision about dry storage for WWER-1000 fuel assembly are discussed. Then the effect of reactor capacity cyclic changes on energy accumulation of creep formations in fuel cladding is covered in full, along with a chapter on the analysis of WWER-1000 fuel cladding failure. Finally, the book finishes with a description of thermal safety criteria for dry storage of spent nuclear fuel. The book is essential reading for anyone concerned with NPP maintenance and safety.







Nuclear Fuel Safety Criteria


Book Description

Presents brief descriptions of 20 fuel-related safety criteria along with both the rationale for having such criteria and possible new design and operational issues which could have an effect on them.




Nuclear Power Reactor Designs


Book Description

Nuclear Power Reactor Designs: From History to Advances analyzes nuclear designs throughout history and explains how each of those has helped to shape and inform the nuclear reactor designs of today and the future. Focused on the structure, systems and relevant components of each reactor design, this book provides the readers with answers to key questions to help them understand the benefits of each design. Each reactor design is introduced, their origin defined, and the relevant research presented before an analysis of its successes, what was learned, and how research and technology advanced as a result are presented. Students, researchers and early career engineers will gain a solid understanding of how nuclear designs have evolved, and how they will continue to develop in the future. - Presents reactor designs through history to present day, focusing on key structures, systems and components - Provides readers with quick answers about various design principles and rationales - Includes new approaches such as the micro-reactor and small-modular reactors




Considerations on the Application of the IAEA Safety Requirements for the Design of Nuclear Power Plants


Book Description

This publication facilitates the understanding and practical application of the IAEA Safety Requirements for the Design of Nuclear Power Plants, SSR 2/1 (Rev. 1), which has been revised after the Fukushima Daiichi accident to strengthen the safety of the plant designs.




Best Estimate Safety Analysis for Nuclear Power Plants


Book Description

Deterministic safety analysis is an important tool for confirming the adequacy and efficiency of provisions within the defence in depth concept for the safety of nuclear power plants (NPPs). IAEA Safety Standards Series No. NS-R-1.2 and Safety Reports Series No. 23 recommend, as one of the options for demonstrating the inclusion of adequate safety margins, the use of best estimate computer codes with realistic input data in combination with the evaluation of uncertainties in the calculation results. The evaluation of uncertainties is an issue of considerable complexity, and this Safety Report has been developed to complement the existing publications. It provides more detailed information on the methods available for the evaluation of uncertainties in deterministic safety analysis of NPPs and practical guidance in the use of these methods.
