The analysis of the radiological impact on the surrounding population and the environment requires the analysis of the vectors causing the dispersion of radioactive nuclides, i. e. the wind and the water, the use of the land and water bodies, the food chain pathways, population distribution and habits. All these studies will serve to limit the radioactive releases to air and water in such a way that the safety objectives are fulfilled in normal operation and countermeasures introduced into the design basis to limit the conse­quences from accidental releases of radioactive nuclides.

The principle on the feasibility of the emergency plans is offered in the following way:
