What safety measures should have been taken in order to prevent the fukushima disaster?

To prevent the Fukushima disaster, several safety measures could have been implemented, including the installation of more robust seawalls to protect against tsunamis, regular seismic assessments to evaluate and reinforce the plant's earthquake resilience, and improved backup power systems to ensure cooling systems remained operational during emergencies. Additionally, better emergency response planning and communication protocols could have enhanced preparedness for such catastrophic events. Finally, stricter regulatory oversight and adherence to international safety standards would have contributed to a more resilient nuclear facility.
