Floating NPP with KLT-40S reactor is ecologically friendly source of energy. The annual radiation dose produced by such a plant is just 1 microSv/year with the natural radiation background affecting a man being 2.4 milliSv/year.

In case of off-design accident at floating NPP the maximum irradiation dose for the personnel is 0.25 milliSv, for the population (in the monitoring zone) – 75 microSv.

This is no more than 0.01% of the natural radiation background. The activity of the nearby water cannot exceed 0.1 Bq/l, which is 100 lower than the allowed activity of drinking water.

Among the non-radiation effects a floating NPP can have on the environment are the effect of discharge of heat into nearby waters, electromagnetic and acoustic effects.

The discharge of heat in case of full capacity:

  • into the air by ventilation system – 270KW; 
  • into nearby waters by generator cooling system – 1650KW; 
  • into nearby water by turbine cooling system – 90MW. 

In winter discharge of circulation water can produce ice-holes: the maximum area of such holes is 44,000 sq m but usually it is no more than 5,000 sq m. The heat emitted by the ventilation systems is not dangerous for the environment.

The chemical, electromagnetic and acoustic impacts the equipment of a floating NPP can have on the environment are localized by design solutions and special measures and are not dangerous for the environment and population.  

The project is based on "build-own-operate" scheme. Russia is not only building the plant but will also ensure its normal operation, maintenance once in 12 years, decommissioning and disposal. The project has done through all legislative examinations and ecological inspection. The plant can stand not only design but also off-design accidents like earthquake or falling plane.
