Regulations for the Safe Transport of Radioactive Material: 2025 Edition
STI/PUB/2120 ¦ English ¦ ISBN 978-92-0-115825-3 ¦ 181 pages ¦ Date published: 2025
This publication is the latest edition of IAEA Safety Standards Series No. SSR-6, Regulations for the Safe Transport of Radioactive Material. It is supported by seven IAEA Safety Guides which provide recommendations for meeting the requirements in SSR-6 to facilitate worldwide implementation. The regulations apply to the transport of radioactive material by all modes on land, water or in the air. Transport comprises the design, manufacture, maintenance and repair of packaging, and the preparation, consigning, loading, carriage including in-transit storage, shipment after storage, unloading and receipt at the final destination of loads of radioactive material and packages. These requirements form an integral part of regulations worldwide; therefore, SSR-6 and its associated Safety Guides are aimed at governments, competent authorities, and all organizations and individuals involved in the transport of radioactive material. These requirements are transcribed into the UN Model Regulations, which are subsequently transcribed into the IMDG Code by the International Maritime Organisation for shipment by sea, and into the Technical Instructions for the Safe Transport of Dangerous Goods by Air by the International Civil Aviation Organization. Both the IMDG Code and the ICAO Technical Instructions are globally implemented and mandatory. Land transport is the responsibility of the national government of each Member State, hence the SSR-6 requirements are adopted for national transport safety regulations for shipments on land.
Approaches to and Preparation for the Operation of Small Modular Reactors
IAEA-TECDOC-2110 ¦ English ¦ ISBN 978-92-0-127825-8 ¦ Date published: 2025
This TECDOC presents state of the art technical information on approaches and preparations for the operation of near term deployable small modular reactors (SMRs). It compares these approaches with the experience and knowledge accumulated from operating commercial nuclear power plants (NPPs) that use large water cooled reactors (WCRs). This publication focusses on near term deployable SMRs with an electrical output of 300 MW(e) or less, planned for grid connection between 2020 and 2035. It identifies the operational and preparatory characteristics of these SMRs from the perspective of plant operators and contrasts them with those of conventional large NPPs. Particular emphasis is placed on operator activities following the loading of the first new fuel assembly into the reactor core, during primary system heat up, and prior to the start of commercial operation. The report also addresses key operational competencies: managing plant control systems and power output during baseload and flexible operation; ensuring fuel integrity; and optimizing the main control room (MCR) layout for both single module and multi module plants, including considerations for human–machine interface (HMI) design.
Development of Waste Acceptance Criteria for Low and Intermediate Level Radioactive Waste
STI/PUB/2117 ¦ English ¦ ISBN 978-92-0-114925-1 ¦122 pages ¦ Date published: 2025
This publication provides practical guidance for the development, implementation and application of Waste Acceptance Criteria (WAC) for the pretreatment, treatment, conditioning, transportation, storage, and disposal of radioactive waste. The WAC approach is largely independent of the type of facility (processing, storage, or disposal) and is appropriate for very low level waste, very short lived waste, low level waste and intermediate activity level short lived waste, including unpackaged waste (for example, parts of decommissioned steam generators or pressure vessels). It can also be applied to the management and disposal of disused sealed radioactive sources declared as radioactive waste. This publication is a valuable resource for all those concerned with the development and implementation of appropriate WACs, including those involved in waste generation, processing and waste package production, as well as regulators, radioactive waste management organizations and technical support organizations.
