Shortly after a 9.0 earthquake shook the ocean floor near Sendai, Japan, a tsunami crashed into the Fukushima Daiichi nuclear plant resulting in a cascade of meltdowns throughout the plant’s reactors. Though at the time of the disaster the plants 4th reactor was undergoing scheduled maintenance and refueling, spent fuel rods were still wallowing in the reactor’s water filled core.
In an effort to remove these spent rods, the plant’s owner and operator (TEPCO) has finally come up with a scheme they believe should get the job done. In the coming weeks, workers will begin using a series of cranes to move spent fuel rods out of the reactor and into waiting containment vessels. Once filled with radioactive material, the vessels will be loaded onto trucks and taken to safe disposal facilities off-site.
Experts expect the complete decommissioning of the facility to take 40 years. Even after the facility is forgotten, however, the remnants of this disaster will remain. We can only hope that future nuclear plants will integrate the lesson learned from Fukushima. Or better yet, maybe we can find an even better source of clean energy.
