If there is a release of radioactivity, ENSI has to assess the consequences and, if necessary, be able to recommend protective measures. With the aid of an atmospheric dispersion calculation, ENSI can predict in which direction a radioactive cloud will move after it escapes from a nuclear installation and which areas will be affected.
The dispersion calculation can be used by the responsible emergency organisations (in particular ENSI and the National Emergency Operations Centre, NEOC) to predict the direction in which a radioactive cloud will move after its release from a nuclear power plant.
Protection of the population and ecosystems take priority if there is an unplanned release of radioactivity. To do so, it is essential to identify the areas most at risk from radioactivity as early as possible. However, before any radioactivity is released (in the pre-phase) no radioactivity measurements are available. Therefore, the hazard can only be…
