The selected systems are phosphates, carbonates, SiO2(s) and SiO2(aq) species, aqueous borate species, aluminium species, magnesium and calcium, solid sodium and potassium carbonates and hydrocarbonates, solid sodium borate, and magnesium and calcium containing minerals.A team, composed of four internationally recognised experts, has critically reviewed all the relevant scientific literature for the above mentioned systems and documented the results in the present volume, which contains new tables of selected values for formation and reaction data and an extensive bibliography.

This volume will be of particular interest to scientists carrying out performance assessments of deep geological disposal sites for radioactive waste. To mark this 20th anniversary, this publication includes papers on several nuclear liability topics and the work of INLEX, contributed by some of the group's current members. The aim of this publication is to increase awareness of the role of INLEX, as well as nuclear liability as an important aspect of nuclear law.

Advancing the State of the Practice in Uncertainty and Sensitivity Methodologies for Severe Accident Analysis in Water Cooled Reactors of CANDU Types
IAEA-TECDOC-2058¦English ¦ Date published: 2024

The IAEA facilitated collaborative research among its Member States, in advancing the state of the practice in uncertainty and sensitivity methodologies for severe accident analysis in water cooled reactors. The primary aim was to evaluate the uncertainty and sensitivity associated with severe accident calculations, particularly concerning the progression and consequences of accidents in a generic CANDU type nuclear power plant under a postulated station blackout scenario.

Key parameters considered in these analyses included hydrogen generation, event timings, and the release of fission products into the environment. The resulting publication showcases contributions from three institutions across three Member States, providing insights into their methodologies for uncertainty and sensitivity analysis in severe accidents.

Milestones in the Development of a National Infrastructure for Nuclear Power
IAEA Nuclear Energy Series No. NG-G-3.1 (Rev.2)¦English ¦ STI/PUB/2073 ¦ 119 pages ¦ Date published: 2024

The decision to develop a nuclear power programme is a significant undertaking by any country. In preparing the necessary nuclear power infrastructure, there are numerous activities that must be completed in a timely manner in line with the objectives of the nuclear power programme.

This publication defines three milestones in the development of the infrastructure necessary for introducing nuclear power and provides guidance on the activities that need to be carried out before each milestone. This new revision incorporates the experiences and feedback from several countries which have already completed or progressed significantly in all three phases. It also includes an annex for outlining the specific infrastructure considerations for Small Modular Reactors, which are expected to be deployed in a number of countries in the coming years. This publication is principally for decision-makers, advisers and senior managers in government, utilities and regulatory bodies in Member States interested in introducing nuclear power.

Summary Report - International Conference on Regulators’ Views and Priorities on Nuclear Safety and Radiation Protection. TEPCO Fukushima Daiichi NPS Accident: 10-Year Reflection, Now and the Way Forward
OECD, Nuclear Energy Agency ¦ English ¦ Date published: 2024

The Nuclear Energy Agency (NEA), in co-ordination with the Nuclear Regulation Authority (NRA) of Japan, hosted the “International Conference on Regulators’ Views and Priorities on Nuclear Safety and Radiation Protection 10 Years After TEPCO Fukushima Daiichi Nuclear Power Station Accident – 10-Year Reflection, Now and the Way Forward”, on 28 and 29 November 2022.

This conference provided an opportunity to bring together high-level regulatory officials from around the world to discuss and reflect on the past, present and future challenges and successes in the field of nuclear safety. The main objective of the conference was to discuss: the developments in national regulatory frameworks after the Fukushima Daiichi Nuclear Power Station accident; the reassessment of safetyrequirements related to natural hazards; trust-building and transparency; and the involvement of women in the nuclear field.

Application of the Principle of Defence in Depth in Nuclear Safety to Small Modular Reactors
INSAG Series No. 28¦English ¦ STI/PUB/2094 ¦ 14 pages ¦ Date published: 2024

This publication developed by the International Nuclear Safety Advisory Group (INSAG) supplements its advice provided in INSAG-10 underscoring application of the principle of defence in depth in nuclear safety for small modular reactors and related emerging technologies. It is intended to stimulate discussion and to promote practical action at all levels to enhance safety of Small Modular Reactors (SMRs).

). INSAG provides recommendations on current and emerging nuclear safety issues to the IAEA, the nuclear community, and the public. The report is intended for use by governmental authorities and by the nuclear industry and its supporting organizations. In particular, the intended audience includes national decision makers for nuclear power programmes using small modular reactors (SMRs), researchers and designers in this field and nuclear and radiation safety experts.

Enhancement of Modelling Approaches for the Assessment of Radionuclide Transfer in the Marine Environment
Report of Working Group 7 - Modelling and Data for Radiological Impact Assessments (MODARIA II) Programme IAEA-TECDOC-2060 ¦English ¦64 pages ¦ Date published: 2024

This publication describes the work undertaken by Working Group 7, Assessment of Fate and Transport of Radionuclides Released in the Marine Environment of the IAEA’s Modelling and Data for Radiological Impact Assessments (MODARIA II) programme (2016–2019).

The work carried out was a natural continuation of that completed during the first phase of the IAEA’s MODARIA programme (2012–2015) by Working Group 10, Modelling of Marine Dispersion and Transfer of Radionuclides Accidentally Released from Land Based Facilities. In MODARIA II, the degree of complexity of the models used was increased in order to effectively consider additional processes, specifically uptake by biota, and the spatiotemporal scales of the simulations were also expanded. General information on the simulation of radionuclides in the marine environment using dispersion and transport models was compiled. This is intended for scientists in Member States considering development or adoption of models for radiological assessment following incidents or emergencies involving releases of radionuclides into the marine environment.
