Deterministic Safety Analysis for Nuclear Power Plants 
IAEA Safety Standards Series, 2009, 84 p.

The objective of this Safety Guide is to provide recommendations and guidance on deterministic safety analysis for designers, operators, regulators and technical support organizations. It also provides recommendations on the use of deterministic safety analysis in: (a) Demonstrating or assessing compliance with regulatory requirements; (b) Identifying possible enhancements of safety and reliability; (c) Obtaining increased operational flexibility within safety limits for nuclear power plants.

The recommendations are based on current good practices at nuclear power plants around the world and derive mainly from experience in performing transient analyses and accident analyses for nuclear power plants.

Approaches and Challenges for the Use of Geological Information in the Safety Case for Deep Disposal of Radioactive Waste
Nuclear Energy Agency (NEA), 09 October 09, 76 p.

A cornerstone of national decision making and societal acceptance of deep geological disposal of radioactive waste is confidence that such repositories can protect humans and the environment both now and in the future. The “safety case” is the synthesis of evidence, analyses and arguments that quantify and substantiate a claim that the repository will be safe after closure and beyond the time when active control of the facility is

ensured. For deep geological disposal, studies of the geosphere form a principal component of the safety case. Geoscientific information is unique in that it can offer evidence and lines of reasoning that span geological timescales (millennia and even longer).

The NEA Approaches and Methods for Integrating Geological Information in the Safety Case (AMIGO) project addresses the collection and integration of geoscientific evidence, analyses and arguments that contribute to an understanding of long-term safety. The third and final AMIGO workshop on “Approaches and Challenges for the Use of Geological Information in the Safety Case” underscored that geoscientific information plays a fundamental role in safety assessments. It is also increasingly used in the wider context of the safety case to provide evidence and arguments for the intrinsically favourable properties of a site, including its long-term stability. No single geoscientific argument “proves” safety, but rather each supports some key element of the safety case and provides enhanced confidence in the safety case. The workshop also considered the links and feedback among the safety case; design, engineering and construction issues; and geoscientific investigations.

Reglamento para el transporte seguro de materiales radiactivos, Edición de 2009 - Requisitos de seguridad 

El presente Reglamento fija normas de seguridad que permiten someter a un grado razonable de control los riesgos inherentes a la radiación y la criticidad, así como los riesgos térmicos, que pueden correr las personas, los bienes y el medio ambiente en relación con el transporte de materiales radiactivos. Este Reglamento se basa en los Principios fundamentales de seguridad, Nociones Fundamentales de Seguridad Nº SF-1 [1], copatrocinados por la Agencia para la Energía Nuclear de la OCDE (AEN), la Euratom, el OIEA, la

Organización de las Naciones Unidas para la Agricultura y la Alimentación (FAO), la Organización Internacional del Trabajo (OIT), la Organización Marítima Internacional (OMI), la Organización Mundial de la Salud (OMS), la Organización Panamericana de la Salud (OPS), y el Programa de las Naciones Unidas para el Medio Ambiente (PNUMA) y en el Vol. Nº 115 de la Colección Seguridad [2], “Normas básicas internacionales de seguridad para la protección contra la radiación ionizante y para la seguridad de las fuentes de radiación”, copatrocinadas por la AEN, la FAO, el OIEA, la OIT, la OMS y la OPS. Así, se considera que el cumplimiento del presente Reglamento se ajusta a los principios de las Normas básicas de seguridad relativas al transporte. De acuerdo con la Ref. [1], la responsabilidad primordial de la seguridad debe recaer en la persona u  organización a cargo de las instalaciones y actividades que generan riesgos asociados a las radiaciones.

Classification of Radioactive Waste - General Safety Guide 
IAEA Safety Standards Series, 2009, 68 p.

The objective of this Safety Guide is to set out a general scheme for classifying radioactive waste that is based primarily on considerations of long term safety, and thus, by implication, disposal of the waste. This Safety Guide, together with other IAEA safety standards on radioactive waste, will assist in the development and implementation of appropriate waste management strategies and will facilitate communication and information exchange within and among States. Disposal is considered the final step in the management of radioactive

waste, as stipulated in Safety Requirements publications on predisposal management of radioactive waste and disposal of radioactive waste [1, 5].

The Safety Guide identifies the conceptual boundaries between different classes of waste and provides guidance on their definition on the basis of long term safety considerations. While the usefulness is recognized of classification schemes for the safe operational management of radioactive waste, including the transport of waste, such schemes are subject to different considerations and are not addressed in this Safety Guide.

A Common Objective, a Variety of Paths. Synthesis and Main Lessons: Third International Conference on Geological Repositories
Nuclear Energy Agency (NEA), 20 October 09, 40 p.

High-level political, governmental and regulatory decision makers, as well as representatives of economic and social groups and implementing organisations met in Berne, Switzerland to present and to reflect on their collective experience towards meeting the challenge of implementing national disposal projects for placing radioactive waste in deep geological formations. This summary highlights the main

lessons to be learnt and final recommendations to assist future developments in national radioactive waste management programmes seeking to meet both technical and social imperatives of modern society.

Leak Detection in Heat Exchangers and Underground Pipelines Using Radiotracers 
IAEA Training Course Series, 2009, 77 p.

The International Atomic Energy Agency plays a major role in facilitating the transfer of radiotracer technology to developing Member States. The use of radiotracer techniques is well established in many Member States; some hundred radiotracer and end user specialists have been trained in radiotracer techniques and their applications; nearly 50 radiotracer laboratories have been working in this field. The training of radiotracer practitioners is vital for the  provision of quality services to industry.

Leak detection using radiotracer techniques is probably one of the most widespread applications of radiotracers in industrial troubleshooting. Radiotracer techniques are the most competitive for online leak inspection of heat exchangers and buried pipelines. Radiotracers help in early detection of leaks in heat exchangers and underground transporting pipelines, thus saving money, reducing shutdown time, ensuring safe operation and protecting the environment from pollution.

The training course series on leak detection in heat exchangers and underground pipelines using radiotracers addresses the needs of the radiotracer groups and their end users. Besides training purposes, this material will assist radiotracer groups in establishing their quality control and accreditation systems.
