Preparation for Potential Severe Accidents
Maintenance and Improvement of Emergency Response Capabilities
*Takahama Units 3 and 4
In preparation for emergencies, Kansai Electric Power consistently ensures the deployment of necessary personnel so that appropriate emergency response actions can be taken even on weekday nights and on weekends and holidays. At the same time, we are making an effort to enhance the emergency response capabilities of those involved by continuously improving our education/training programs. In addition, we have placed an organizational system to ensure that plant vendors and manufacturers can provide timely technical assistance as well as materials and equipment.
Education/Training Program on an Assumption of an Accident
Integrated Nuclear Disaster Prevention Drill
Integrated nuclear disaster prevention drills are conducted assuming a severe accident during which all on-site power supplies are lost, disabling cooling of the reactor.
- Mobilization drill on an assumption of an emergency
- Drill on transportation of materials/equipment by a helicopter
- Drill on manipulation of remote control robots
Drill on power supply
Drills on connection and startup of a power supply car are conducted on an assumption of unavailability of power supply from transmission lines and diesel generators. In addition, nighttime drills are also conducted.
- Nighttime drill on connection/startup of power supply cars
- Drill on installation of large capacity pumps
- Drill on the installation of pumps injecting coolant into reactor
- Drill on installation of fire pumps while putting protective clothes and masks on an assumption of adverse conditions.
Drill on control of radioactive release
Drills on control of radioactive release to the environment are conducted on an assumption of containment vessel failure.
- Drill on water discharge directly to the containment utilizing water cannons to mitigate radioactive release
Drill on removal of rubbles using a heavy machine
Drills on removal of rubbles using heavy machines deployed on-site are conducted to ensure the access of workers and vehicles as well as passages assuming that a tsunami or flooding makes rubbles being scattered across the site area.
- Drill on use of the dozer shovel to remove rubbles
Drill on operations in the event of loss of power supply
Drill on emergency operations are conducted to enhance operators’ capabilities safety terminate the events under adverse conditions assuming a loss of all on-site power supplies.
- Simulator training on an assumption of loss of all power supplies
