Integrated risk management strategic technical
The management of a nuclear accident involves many actors apart from the radiation protection and nuclear safety experts, such as the emergency services, the local authorities. An efficient involvement of these stakeholders requires a good understanding of the safety and radiation protection aspects of the different steps of the management of a nuclear crisis: what is the nature of the accident? What are the expected releases? What is the potential exposure of the population? What are the various short term and long term countermeasures (sheltering, stable iodine intake, food banning, environment remediation, etc.) and what is the rationale for their implementation? In addition, there are also neighbours of nuclear installations (inhabitants, local associations and commissions, local political representatives) that would be impacted by a nuclear accident and thus wish to be informed and associated to the emergency preparedness process.
In order to contribute to building progressively a common nuclear risk culture between the already active stakeholders and the new stake-seekers, the information about the accidental risk and its management needs to be clearly presented and offered to the debate. Hence, IRSN decided in year 2000 to elaborate a specific feature providing an opportunity for better information and debate.
A CD-ROM is currently being elaborated by a multidisciplinary task group, taking into account:
· the « social expectancies », as they have been identified by a sociologist,
· the existing documents about the nuclear risk, the crisis and its management, which were analysed. The analysis shows that there is a need for a new type of feature.
The CD-ROM will contain first a common bulk, which addresses ail types of nuclear accidents:
· general considerations about radiological risks,
· general considerations about the types of accidents which can occur in a nuclear installation the associated releases and the actors that would be involved,
· exposure pathways of man and environment,
· health and medical dimensions of a nuclear accident,
· short term and long term countermeasures,
· post- accident management.
The CD-ROM will contain also specific developments for each type of accidents occurring in different nuclear installations, namely nuclear power plants:
· potential radiological consequences of the accidental release,
· implementation of short term countermeasures and their related efficiency,
· efficiency of post-accident countermeasures and remediation actions.
·This complete picture given by the description of accidents, their consequences and the protective actions is a very innovative dimension of the project, and is made to show the very large and complex interactions in time and space between the many actors that would be involved.
Specialists in CD-ROM design are involved in the project. It is very important to design the structure of the CD-ROM in such a way as it presents the technical information in an understandable and attractive manner for non-specialists and in various ways.
This CD-ROM, which should be widely distributed and will serve as a support for debates, may contribute to building up progressively a common risk culture. It should help to aim at a better mutual understanding between experts and lay people whose points of view about the nuclear risk management need to be properly taken into account. This should tend to improve the risk management strategies, short and long terns.
