Radiation and Nuclear Safety Authority’s (STUK) regulation, which will applied from the first day of February onwards, no longer stipulates a five-kilometer precautionary action zone nor a 20-kilometer emergency planning zone around all nuclear power plants.


In the future, those applying for a license for a power plant must each time separately indicate to the supervising authority what kind of protection zones are needed to guarantee safety. People and the environment must be as safe as they have been so far.


The new regulation applies to all possible nuclear power plants. For the so-called small nuclear power plants (small modular reactor, SMR) that have been in the public eye recently, the change means that if safety can be demonstrated, the plants could be built closer to the population than would be possible with the old regulation in force.
