This is the 41st edition of Reference Data Series No. 2, which presents the most recent reactor data available to the IAEA. It contains summarized information as of the end of 2020 on power reactors operating, under construction and shut down as well as performance data on reactors operating in the IAEA Member States. The information is collected through designated national correspondents in th…
Given the increasing interest of Member States in the near term deployment of SMRs, this publication presents several model technology roadmaps that States can adapt for their specific projects. For nuclear newcomer countries, these roadmaps assume that a Member State has already developed, or is at least well along the way to developing, the infrastructure necessary to carry out a nuclear powe…
The objective of this publication is to provide specific guidance for accident analysis for nuclear power plants with pressurized water reactors, taking into account the specific design features of these reactors. This guidance covers all steps required to perform such analyses, including selection of initiating events, acceptance criteria, computer codes, modelling assumptions, preparation of …
The assessment approach described in this publication provides a comprehensive means to determine the status of the infrastructure conditions relevant to all issues detailed in IAEA Nuclear Energy Series No. NP-T-5.1, Specific Considerations and Milestones for a Research Reactor Project. This approach can be used by any interested Member State for self-assessment to identify weaknesses and to d…
This publication presents a summary of discussions from a consultants meeting on the merits and challenges associated with the operation of aqueous homogeneous reactors (AHRs) for the production of the isotope technetium-99m (99mTc) and includes the technical presentations given by the participants during the meeting. Currently, 80% of all radiopharmaceutical procedures employ 99mTc, a product …
Following the accident at the Fukushima Daiichi nuclear power plant, combustible gas behaviour and related accident management measures have been the subject of increased study and analysis. This has included on measures to limit the fission product release into the environment. This publication reviews the current state of technology regarding combustible gas related safety issues in water coo…
IAEA Member States have expressed relevant interest in the development and deployment of small and medium-sized or modular reactors (SMRs) to help cover their energy needs in the coming decades. SMR designs may include technological characteristics that differ significantly from those of the large nuclear power plants that are commercially available. Those SMR characteristics can represent a ch…
Fuel acceptance criteria can be used, among other things, as key inputs in the determination of operating limits and conditions for reactor operational states, in the determination of fitness for service criteria for anticipated operational occurrences, in the formulation of special safety system trip set points for accident conditions, and in the determination of a plant's safe operating envel…
This report presents guidelines to the designers of water cooled power reactors which will minimize the impact of IAEA safeguards on plant operations and ensure efficient and effective acquisition of safeguards data to the mutual benefit of the Member State, the plant operator and the IAEA. These guidelines incorporate the IAEA's experience in establishing and carrying out safeguards at current…
An important characteristic of research reactors is that they are interdisciplinary tools that can be used in a variety of fields: scientific research, applied or engineering oriented research and training. The results find applications in medicine and agriculture as well as in industrial processes in the form of nuclear techniques which may be cheaper and faster and in many cases may provid…
