Safety Measures Implementation at Kashiwazaki-Kariwa Nuclear Power Station

Emergency Safety Training at Kashiwazaki-Kariwa Nuclear Power Station

Outline of Emergency Safety Training

The procedures to follow when the power supply functions are disabled due to Tsunami have been newly developed. The effectiveness of the new procedures was evaluated through a comprehensive safety training utilizing the deployed power supply cars and fire engines.

[Setting up the procedures (Completed)]
- The situation similar to the accident at Fukushima Daiichi Nuclear Power Station is assumed (Station blackout after Tsunami hits. External power supply, emergency diesel generators and seawater system pumps are all disabled).
- Based on the above situation, procedures were set up to achieve water injection to the reactor, cold shut-down and cooling the spent fuel pool.

[Comprehensive training (Held 4 times, approx. 620 people participated]
- Emergency training was held based on the procedures set up.
- Equipments/materials prepared for emergency use (such as power supply cars) were deployed. The operations during night time were also covered.
- It was confirmed that the preparation can be completed within 8 hours (target) even when the staff are to come to the station on foot.

[Other training activities]
- Receiving power from the power supply car to the power panel
- Opening the top vent and the blow-out panel
- Handling power cable terminals in the dark
- Operating the fire engine etc.
