 We turn turbine with steam and, at nuclear power plant, generate electricity.
 Steam which we used for generation cools off and gets back to water, but will use a large quantity of seawater as coolant then.
 When we drew water, we compare, and this coolant is released with temperature rise to the sea. We call this released seawater on*sui generally.
 We carry out Surveys about influence that on*sui gives to neighboring environment and living things in the prefecture.

 

 

Diffusion Surveys of on*sui

 We establish Surveys point in peripheral sea area to grasp the diffusion situation of on*sui and measure water temperature. 

 

The quality of the water Surveys

 We establish Surveys point in peripheral sea area to grasp change of the quality of the water by on*sui and carry out Surveys about hydrogen-ion concentration (pH), oxygen content of water (DO), quantity of chlorophyll -a, turbidity. 

  

Periphyton Surveys

 We establish Surveys point in the neighboring shores to grasp influence that on*sui gives to living thing and carry out type of animal and plant and Surveys of cover degree.
