The heads of the national nuclear and radiation safety regulators in Europe have developed and agreed on a new approach to further improve the response and cross-border coordination for all types of possible accident scenarios including severe accidents, like the one in Fukushima. It contains overarching principles and provides an incentive for joint actions between neighbouring countries. The regulators have committed to engage a cooperation at national level with the competent authorities in charge of civil protection for the implementation of the corresponding measures.
