Washington Post : Almost five years after the Fukushima Daiichi nuclear disaster, the Tokyo Electric Power Co still has a lot of work to do to dispose of contaminated water and soil and nuclear fuel debris. Radiation readings have dropped but are still at the upper end of safe, and several neighboring towns remain vacant of inhabitants. To try to stop the flow of groundwater into the reactor buildings, where it becomes contaminated, Tepco has been building an ice wall to freeze the soil. However, the plan has been put on hold by Japan’s Nuclear Regulation Authority, which says the risk of leakage is still too high. According to one Tepco official, the entire decommissioning process is only about 10% complete.
