Management of the Post‐accident Phase

The post-accident phase is generally divided into two periods. The first period is transitional and the second (very long) period corresponds to the post-accident phase itself. In each period, various actions must be taken. For example, in the case of France, the French Nuclear Safety Authority has published elements of the doctrine for the post-accident management of a nuclear accident. Managing a post-accident phase is a long term and very costly operation, in which the authorities must be able to adapt permanently to situations that are difficult to predict. It is essential that this management is organized before the possible accident. This management must be considered in three main areas: environmental management, anthroposphere management and management of exposed populations. Post-accident management is the responsibility of each state. However, international organizations make their expertise available to states in the form of recommendations.
