In Pursuit of Greater Safety -Maintaining Continuous Efforts for Safety-
Emergency Response Drill
On February 7, 2014, an emergency response drill was conducted with the purpose of understanding and maintaining / improving technical skills of response personnel and the function as a disaster response organization during a nuclear disaster. Approximately 500 Hamaoka Nuclear Power Station workers from Chubu Electric Power Co., Inc. and subcontractors participated in the drill.
The drill was carried out assuming the situation, in which a large-scale earthquake with a seismic intensity of 7 occurred at 8:30AM on a holiday with the subsequent tsunami resulting in a complete loss of AC power similar to that of Fukushima Daiichi.
At the Emergency Response Center serving as the control center when accidents or disasters occur, five shift workers checked immediately after the earthquake whether the power station had safely shut down, and contacted and reported to the Nuclear Regulation Agency and our head office using satellite phones, assuming that the phone lines could not be used. In this manner initial response procedures were confirmed.
1 hour after the earthquake occurred, more than 100 response personnel gathered at the Emergency Response Center. The personnel then divided into groups to perform drills for ensuring the functionality to cool the reactor, such as setting up power cable connections for supplying power from emergency generators, and laying hose for performing alternative water injection from portable power pumps.
