Preserving the Environment

We Strive to Achieve Harmony with Local Environments in the Operation of Our Power Plants.

Each and every employee of JAPC has a great awareness of the environment and is involved in efforts at power plants that aim for operations that lead to a low-carbon society as well as promotion of environmental preservation in each area.

 

Our Power Stations Environmental Management

To Achieve Harmony with the Environment

Through our business activities, we endeavor to bring joy and comfort to all living creatures on earth and share happiness with local communities while gaining the trust and confidence of all and contributing to the growth of nuclear power generation.

Our Power Stations Environmental Policies

  1. Contributing to the prevention of global warming through the safe operation of nuclear power plants
  2. Setting goals for environmental activities and making continuous improvements in our environmental management system
  3. Compliance with environmental laws and agreements and prevention of environmental pollution
  4. Reduction in the amount of radioactive gaseous and liquid waste discharged
  5. Reduction in the amount of radioactive solid waste discharged and reduction of the volume of solid waste
  6. Energy saving, efficient use of resources and promotion of the 3 R's(Reduce, Reuse and Recycle) of waste
  7. Making environmental policies known to all employees and raising the environmental consciousness of all power plant workers
  8. Achievement of harmony with the natural landscape and protection of the natural environment
  9. Active participation in local environmental activities as members of the community
 

First nuclear power plant in Japan to obtain ISO 14001 certification

In February 1998, Tokai No. 2 Power Station and Tsuruga Power Station obtained ISO 14001 certification for their environmental management systems —a first for nuclear power stations in Japan.
Our power stations continue environmental management activities.

 

Establishing Power Plants through Environmental Assessment

We are implementing various environmental preservation measures in the construction of Tsuruga Power Station Units 3 and 4 in accordance with the construction progress. To reduce the impact of the construction on the surrounding environment, proper environmental preservation measures, based on an environmental
impact assessment conducted in advance, are taken according to the progress of the construction.
For example, to protect plants during the site preparation work, we have transplanted seven types of plants including Chrysanthemum wakasaense and Iris ensata var. spontanea. We also monitor the growth of the plants after they are transplanted and confirm that they are growing well.

Monitoring of the Environment around Power Stations

Monitoring of the environment around power stations

Our company and the local government set up equipment (such as monitoring posts) in areas surrounding power stations in order to measure and monitor the radiation effect on the environment. Monitoring results are displayed in real-time on JAPC's website. We also periodically collect samples of seawater, soil from the sea bottom and land, crops and drinking water in the areas around power stations and we measure the concentration of radioactive substances in order to confirm that no radiation effects are observed in the environment.

Surveys on the environmental effects of thermal effluent

At power stations, the steam used to rotate turbines is cooled by seawater. Seawater that has been used to cool steam is discharged into the sea. We have conducted periodic surveys on the effects of this thermal effluent since our power plants went into operation.
No impact of thermal effluent on the environment has so far been observed in the areas around the Tokai No. 2 and Tsuruga Power Stations.

Initiative for the Promotion of a Recycling-based Society

Efficient use of resources

We are working to promote the 3 R's (Reduce, Reuse and Recycle) of industrial waste and nonindustrial
waste. For example, we reduce waste oil as much as possible, reuse lubricating oil for electric motors, make compost from garbage discharged from company canteens to recycle it as fertilizer, and use a solid substance made from jellyfish trapped inside water intakes as cement
material.

We are working to plant and preserve trees within the sites of our power stations and in surrounding areas.

To preserve the natural environment, we administer injections to trees to protect them from damaged by pine weevils, we cut down sick trees, and we plant trees where too many trees have been harvested.

Processing methods of Radioactive Waste

We strive to minimize the environmental impact of radioactive waste (gas, liquid, solid) generated in the course of operating a nuclear power station by eliminating the radioactive materials, or reducing or storing the radioactive waste.
