Recently, the IAEA saw an increase in the participation of Member States in its programme for the technology development of SMRs. The driving forces in the development of such reactors are: meeting the need for flexible power generation for wider range of users and applications; replacing the ageing fossil fuel-fired power plants; enhancing safety performance through inherent and passive safety features; offering better economic affordability; suitability for non-electric applications; options for remote regions without established electricity grid infrastructures; and offering possibilities for synergetic energy systems that combine nuclear and alternate energy sources. The trend in development has been towards design certification of small modular reactors, which are defined as advanced reactors that produce electric power up to 300 MW(e), designed to be built in factories and shipped to utilities for installation as demand arises. These new factory-built designs aim to reduce lengthy construction times while simultaneously increasing quality, thereby minimizing the financing costs associated with nowadays construction projects that span 5–8 years. SMR designs include water-cooled reactors, high temperature gas cooled reactors, as well as liquid metal cooled reactors with fast neutron spectrum. Some of SMRs are to be deployed as multiple-module power plants. Several countries are also pioneering in the development and application of transportable nuclear power plants, including floating and seabed-based SMRs. The distinct concepts of operations, staffing and security requirements, size of emergency planning zones (EPZs), licensing process, legal and regulatory framework are the main issues for the SMRs deployment. The projected timelines of readiness for deployment of SMRs generally range from the present to 2025–2030. Member States, both those considering their first nuclear power plant and those with an existing nuclear power programme, are interested in information about advanced SMR designs and concepts, as well as new development trends. The IAEA Department of Nuclear Energy, which has been facilitating Member States in addressing common technologies and issues for SMRs and related fuel cycles in the past three decades, plays a prominent role in presenting international scientific forums and technical cooperation in this field for interested Member States. The IAEA has been regularly publishing booklets on the status of SMR technology developments with the objective to provide Member States, including those considering initiating a nuclear power programme and those already having practical experience in nuclear power, a balance and objective overview of the status of SMR designs. This booklet is reporting the advances in global development of small modular reactor designs and technologies. This booklet covers only water-cooled and high temperature gas cooled small modular reactor designs and technologies. As for various small reactors with fast neutron spectrum, they are reported in a recent dedicated booklet on status of innovative fast reactor designs and concepts (see Annex III). This booklet is intended as a supplement to the IAEA Advanced Reactor Information System (ARIS), which can be accessed at http://aris.iaea.org. This publication was developed by Nuclear Power Technology Development Section, Division of Nuclear Power of the IAEA Department of Nuclear Energy in cooperation with Member States. The IAEA acknowledges the roles and contributions of A. Iunikova in coordinating the development of this booklet. The IAEA officers responsible for this publication were H. Subki and F. Reitsma of the Division of Nuclear Power.

Advanced SMRs having an equivalent electric power of less than 700 MW(e) or even less than 300 MW(e) are part of a new generation of nuclear power plant designs being developed to provide a flexible, cost-effective energy for various applications. Advanced SMR designs include water-cooled reactors, high-temperature gas cooled reactors, as well as liquid-metal cooled reactors with fast neutron spectrum. The trend of development has been towards design certification of small modular reactors, which are defined as advanced reactors that produce equivalent electric power less than 300 MW(e) designed to be built in factories and shipped to utilities for installation as demand arises. The SMR systems adopt modularization, by which the structures, systems and components are shop-fabricated then shipped and assembled onsite, thus the construction time for SMRs can be substantially reduced. Some of the SMRs are to be deployed as multiple-module power plants allowing utilities to add additional reactor and power conversion modules as demand for local power increases. Advanced SMRs will use different approaches from large reactors for achieving a high level of safety and reliability in their systems, structures, components, and that will be the result of a complex

Canadian Nuclear Safety Commission - R550.1 Survey of Design and Regulatory Requirements for New Small Reactors, Contract No. 87055-13-0356 Final Report - July 3, 2014 Executive Summary The objectives of this report are to perform a design survey of small modular reactors (SMRs) with near-term deployment potential, with a particular emphasis on identifying their innovative safety features, and to review the Canadian nuclear regulatory framework to assess whether the current and proposed regulatory documents adequately address SMR licensing challenges. SMRs are being designed to lower the initial financing cost of a nuclear power plant or to supply electricity in small grids (often in remote areas) which cannot accommodate large nuclear power plants (NPPs). The majority of the advanced SMR designs is based on pressurized water reactor (PWR) technology, while some non-PWR Generation IV technologies (e.g., gas-cooled reactor, lead-cooled reactor, sodium-cooled fast reactor, etc.) are also being pursued.

  • Russia Highly Appreciates the Activity of IAEA and Its Role in Promoting "Peaceful Atom” in Every Aspects of Life
    Unofficial translation Dear colleagues, ladies and gentlemen! Russia highly appreciates the activity of IAEA and its role in promoting "peaceful atom” in every aspects of life. We strongly support Agency's activities in the field of nuclear science and technology, participate in virtually all areas of activity and provide our knowledge, experience, educational opportunities and experimental facilities to promote this important industry. We are convinced that nuclear and radiation technologies, based on solid foundation of science, will make a significant contribution to achievement of Sustainable Development Goals of mankind, including problems of climate and power supply. The strategic goal of Russian nuclear industry is to ensure the innovative development of our country based on the expansion of application of nuclear technologies in various sectors of the economy. The focus is traditionally set on the development of nuclear energy technologies. We are convinced that the future of nuclear energy is inextricably linked with the closure of the nuclear fuel cycle. Russian scientists have already made a significant contribution to the development and commercialization of this direction, demonstrating to the world the operability and attractiveness of its key element - fast neutron reactor of 4th generation. This was the basis for the development and implementation of the Breakthrough project with a demonstration of technical solutions for existing challenges, nuclear power industry faces today: critical decision to increase the safety of nuclear power generation is the transition to “natural safety” reactor systems and the resolution of issues related to the management of spent nuclear fuel and radioactive waste. Undoubtedly, one of the components of new technological platform is the development of low and medium power sector of nuclear power industry.

  • Russia's Akademik Lomonosov – the First Modern Floating Nuclear
    Russia’s Akademik Lomonosov – The First Modern Floating Nuclear Power Plant (FNPP) Peter Lobner, 15 May 2021 1. Introduction Designated Project 20870, construction of Akademik Lomonosov started on 15 April 2007, when the keel was laid at the Sevmash shipyard in Severodvinsk, which also is Russia’s premier submarine building shipyard. Originally, Akademik Lomonosov was expected to supply power to the Sevmash shipyard itself and the town of Severodvinsk, in Northwest Russia. Cutaway drawing showing the general arrangement of the Akademik Lomonosov. Source: Rosatom In August 2008, the hull of Akademik Lomonosov was transferred to the Baltic Shipyard in St. Petersburg, where a second “keel laying” was held in May 2009. Plans for deploying the FNPP were reconsidered, leading to the final selection of Pevek, a remote Arctic coastal city in Russia’s Far East. The FNPP was launched on 30 June 2010 and outfitting continued with the vessel secured dockside at the Baltic Shipyard. Two un-fueled OKBM Afrikantov KLT-40S modular pressurized water reactors (PWRs) were installed in October 2013. 1 After work on the vessel and reactor systems was completed in April 2018, Akademik Lomonosov was towed 4,000 km (2,485 miles) around Norway to Murmansk, where the reactors were fuelled and tested at Rosatomflot facilities, which also support their nuclear- powered icebreaker fleet. In June 2019, the Russian nuclear regulatory agency Rostekhnadzor issued a 10-year license to Rosenergoatom to operate Akademik Lomonosov until 2029. After successfully completing testing, Akademik Lomonosov departed Murmansk on 23 August 2019 and was towed 4,770 km (2,964 miles) along the Northern Sea Route, arriving at its final destination on 9 September 2019 at a new protected pier at Pevek, which is about 980 km (609 miles) west of the Bering Strait.

  • Core Design and Optimization of the High Conversion Small Modular Reactor
    Technische Universität München Fakultät für Maschinenwesen Lehrstuhl für Nukleartechnik Core Design and Optimization of the High Conversion Small Modular Reactor Denis Janin Vollständiger Abdruck der von der Fakultät für Maschinenwesen der Technischen Universität München zur Erlangung des akademischen Grades eines Doktor-Ingenieurs (Dr.-Ing.) genehmigten Dissertation. Vorsitzender: Prof. Phaedon-Stelios Koutsourelakis, PhD Prüfer der Dissertation: 1. Prof. Rafael Macián-Juan, PhD 2. Prof. Dr. Jean-Baptiste Thomas Die Dissertation wurde am 08.05.2018 bei der Technischen Universität München eingereicht und durch die Fakultät für Maschinenwesen am 01.11.2018 angenommen. ABSTRACT This research work investigates the design and optimization of the high conversion small modular reactor (HCSMR) core. The HCSMR has a thermal output of 600 MW for 200 MW electrical. It is an integrated PWR with a tightened fuel assembly lattice. The rod-to-rod pitch is 1.15 cm in a hexagonal fuel assembly geometry. As a result the moderation ratio (1.0) is reduced compared to large PWRs (around 2.0) and the HCSMR has an improved ability to convert 238U into 239Pu and use plutonium isotopes more efficiently. The core is loaded with MOX fuel. The HCSMR concept finds its roots both in large high conversion light water reactors and small modular reactor (SMR) concepts. The reduced core size results in an increased neutron leakage rate compared to large cores. This intrinsically supports the core behavior in voided situations. The necessity to introduce fertile fuel materials in the core to keep negative void coefficients is reduced, contributing to the HCSMR safety and limited core heterogeneity.

  • 60 Years of Marine Nuclear Power: 1955
    Marine Nuclear Power: 1939 - 2018 Part 4: Europe & Canada Peter Lobner July 2018 1 Foreword In 2015, I compiled the first edition of this resource document to support a presentation I made in August 2015 to The Lyncean Group of San Diego (www.lynceans.org) commemorating the 60th anniversary of the world’s first “underway on nuclear power” by USS Nautilus on 17 January 1955. That presentation to the Lyncean Group, “60 years of Marine Nuclear Power: 1955 – 2015,” was my attempt to tell a complex story, starting from the early origins of the US Navy’s interest in marine nuclear propulsion in 1939, resetting the clock on 17 January 1955 with USS Nautilus’ historic first voyage, and then tracing the development and exploitation of marine nuclear power over the next 60 years in a remarkable variety of military and civilian vessels created by eight nations. In July 2018, I finished a complete update of the resource document and changed the title to, “Marine Nuclear Power: 1939 – 2018.” What you have here is Part 4: Europe & Canada. The other parts are: Part 1: Introduction Part 2A: United States - Submarines Part 2B: United States - Surface Ships Part 3A: Russia - Submarines Part 3B: Russia - Surface Ships & Non-propulsion Marine Nuclear Applications Part 5: China, India, Japan and Other Nations Part 6: Arctic Operations 2 Foreword This resource document was compiled from unclassified, open sources in the public domain. I acknowledge the great amount of work done by others who have published material in print or posted information on the internet pertaining to international marine nuclear propulsion programs, naval and civilian nuclear powered vessels, naval weapons systems, and other marine nuclear applications.
