Radiation Protection in Newer Medical Imaging Techniques:
CT Colonography 
IAEA Safety Reports Series, 2009, 27 p.

This publication has been developed by the IAEA in collaboration with the World Health Organization, the International Society of Radiology and the International Commission on Radiological Protection. It addresses issues associated with high patient doses received from multi-detector CT (MDCT) in colonography and provides data on patient dose and risk levels, as well as information for practitioners on optimizing techniques.

Sustaining Global Best Practices in Uranium Mining and Processing - Principles for Managing Radiation, Health and Safety, Waste and the Environment
World Nuclear Association (WNA), 2008, 16 p.

The worldwide community of professionals engaged in uranium mining and processing recognizes that managing radiation, health and safety, waste and the environment is of paramount importance for the protection of workers, the public and the environment. This recognition – and the acceptance of commensurate responsibility – is fundamental to our vision, values and measures of success.

Such responsible management of uranium mining and processing projects applies at all stages of planning and activities – from exploration throug h development, construction and operations, and on to decommissioning. Today we are acting to ensure that all parties directly involved in uranium mining and processing – including operators, contractors, and regulators – strive to achieve the highest levels of excellence in these fields of management. We are doing so by sustaining a strong safety culture based on a commitment to a framework of common, internationally shared principles.

Structuring Nuclear Projects for Success: An Analytic Framework
World Nuclear Association (WNA), August 2008, 24 p.

Recent years have seen a transformation both in the actual economics of nuclear power and also in the widening recognition that it occupies an increasingly strong position in the energy marketplace. A growing community of investors now understands that existing nuclear power plants are highly economic. Power prices have risen sharply with the escalation of oil and gas prices, while well-run nuclear plants have stable and predictable operating costs that ensure excellent profitability

for their owners in any type of electricity market.
The economics of new nuclear plants are more challenging and are documented in a number of publications, including the WNA Report entitled "The New Economics of Nuclear Power" issued in late 2005. It has however become clear that, even with the most cautious assumptions on costs of plants, the price of natural gas and other relevant variables, new nuclear plants can now be economically viable.
This prospect is strengthened by the likelihood that public policies will focus increasingly on penalizing energy technologies that produce carbon emissions. Economic viability, however, is only one aspect that investors must consider when contemplating new nuclear projects. They have somewhat unique characteristics. They are capital intensive, with very long project schedules and have significant fixed operating and maintenance costs but relatively low fuel costs.
They exist in a rigorous regulatory environment where the regulator very actively patrols the plant's operations and has considerable authority that can impact on both unit construction and operations. Many utilities are extremely risk averse, some of them having suffered through projects that did not meet expectations in the past. Given the long period of time without any substantive new build projects, they are looking for ways to boost confidence that plants will be built to budget and schedule, so that the promise of good economic performance will be realized. This report describes the key risks facing those who are looking to build new nuclear plants and then demonstrates that a good structure is essential for project success.

Second Follow-up IAEA Mission in Relation to the Findings and Lessons Learned from the 16 July 2007
IAEA, December 2008, 111 p.

The safe performance of the Kashiwazaki-Kariwa nuclear power plant during and after the earthquake that hit Japan´s Niigata and Nagano prefectures on 16 July 2007 has been confirmed, according to a IAEA report published today.
The report is the third in a series issued by an IAEA-led team of international experts that completed its mission in December 2008. Two previous missions were carried out by the same team in August 2007 and January 2008. All missions were

carried out at the invitation of the Government of Japan.
The consequences of the July 2007 earthquake on the plant were unique in the sense that the levels of seismic ground motion estimated in the design process were very significantly exceeded by the event. The mission found that there is consensus in the scientific community about the causes of those unexpectedly large ground motions experienced at the plant site and, consequently, it has been possible to identify the precautions needed to be taken in relation to possible future events and the newly calculated seismic hazard at the site is much higher than both the July 2007 event and the original design earthquake level.
These precautions were based on extensive studies and assessments conducted by a number of specialized institutions and experts in different fields. The necessary upgrades and actions were consequently defined and are being implemented by the Japanese utility for both safety and non-safety related components at the nuclear power plant.

IRPA Guiding Principles for Radiation Protection Professionals on Stakeholder Engagement
International Radiation Protection Association (IRPA), s. d., 9 p.

IRPA Guiding Principles for Radiation Protection Professionals on Stakeholder Engagement is intended to provide to help radiation protection professionals to understand the objectives, requirements and demands of stakeholder engagement, encourage participation and provide a framework for establishing a constructive dialogue with other stakeholders.  This document is presented following discussion at the Associate Societies Forum during the 12th International Congress IRPA in Buenos Aires.

Model Constitution for IRPA Associate SocietesInternational Radiation Protection Association (IRPA), s. d. 11 p.

The Model Constitution for IRPA Associate Societies is designed to assist societies that are forming and wish to become associated with IRPA. It will ensure that the IRPA requirements for the constitution are met. It is only a tool to help in the development of Associate Society Constitutions and need not be followed.

Release of Radioactive Materials and Buildings from Regulatory Control
A Status Report Nuclear Energy Agency (NEA) - OCDE, 19-NOV-08, 72 p.


The radiological concept of clearance can be defined as the release of radioactive materials or buildings from any further regulatory control applied for radiological protection purposes by the competent body. It is generally based on the assumption that, following clearance, any potential radiological exposure of the public will be trivial.

Clearance is now a mature concept being used for the management of large amounts of radioactive materials (including metals, building rubble, cables and plastics) and disused buildings associated with a controlled nuclear activity. There are, however, differences in the ways in which clearance is dealt with in the regulatory frameworks of various countries and the ways in which clearance has been implemented in diverse decommissioning projects.

This report provides up-to-date information on an array of national approaches to clearance. It should be of particular help to those planning the implementation of a clearance procedure, such as that for decommissioning a nuclear facility.

This publication is also available in French as: Libération des matériaux et bâtiments radioactifs du contrôle réglementaire - Rapport de synthèse:
