Nearly nine years after the accident, the decommissioning of the plant, where three reactors melted, remains largely an uncertainty. The revised road map, to be formally approved later this month, lacks details on how the complex should look at the end but maintains a 30- to 40-year target to finish.MELTED FUEL DEBRIS
Earlier, assessment at Unit 3 was hampered by high radiation and water levels in its primary containment vessel. A robotic survey at Unit 1 was unsuccessful due to extremely high radiation levels. TEPCO says it has space to store only up to 1.37 million tons until the summer of 2022, raising speculation that the water may be released after the Tokyo Olympics next year. TEPCO and experts say the tanks get in the way of decommissioning work and they need to free up the space to build storage for debris removed and other radioactive materials. The tanks also pose risks if they were to spill out their contents in another major earthquake, tsunami or flood.
Fukushima is a serious problem for Japan. In the decade since the disaster radioactive soil/water has been stored temporarily in bags/tanks while tons of toxic water flows into the ocean despite an ice barrier. The technology isn't in place to clean up a disaster of this scale
