In Pursuit of Greater Safety
No More Fukushima Daiichi Accidents
Hamaoka Nuclear Power Station has always embraced the most up-to-date knowledge in its effort to enhance safety. Following the accident at TEPCO’s Fukushima Daiichi Nuclear Power Station, we have been implementing voluntary countermeasures for tsunami and severe accidents countermeasures, and introducing additional measures in light of the New Regulatory Requirements*1 so as to build up our safety.
“No More Fukushima Daiichi Accidents” With this firm resolve, Hamaoka Nuclear Power Station is making all-out efforts for safety.
Fundamental Principles of Safety for Nuclear Power Stations (3 steps)

With nuclear generation, fuel continues to generate heat even after the plant operation is "shut down". This is why it is important to keep "cooling" fuel by way of injecting water into the reactor and "contain" radioactive materials. In the Fukushima Daiichi accident, the power station failed in "cooling", which led to the failure to "contain" radioactive materials.
