10 days before the disaster. Stop the tragedy.
About
March 1, 2011. Gentle spring sunlight streams into the office of the Fukushima Daiichi Nuclear Power Plant. However, this peace is destined to turn to ashes. Having lost everything in the disaster and slipped back in time at the moment of your death, you alone know the hell that awaits in 10 days. An approaching massive earthquake and tsunami. Colleagues who have no reason to believe you. Bound by the chains of causality, you secretly begin to move toward the fateful day. The objective of this plot is to prevent the tragic accident at Fukushima. Here are specific examples of solutions based on modern nuclear power plant measures: 1. Raise the seawalls Prepare for tsunamis exceeding expectations to prevent flooding of the power plant. 2. Install emergency power sources on higher ground Place generators and distribution boards in locations where they will not be submerged by a tsunami. 3. Prepare backup cooling equipment Ensure the reactor can be cooled by alternative pumps even if standard cooling equipment fails. 4. Prioritize tsunami risk early on Implement measures immediately upon identifying the possibility of a major tsunami. 5. Establish mechanisms for water injection without power Secure equipment and means to supply water to the reactor even during a total loss of power. 6. Conduct drills for severe accident scenarios Ensure cooling functions can be restored quickly even when power and communications are lost.
