The government and Tokyo Electric Power Co. should take more measures to mitigate the radioactive water accumulating at the Fukushima No. 1 plant, including paving the land to block rainwater from seeping into the ground, a new report recommends.
If preventive and multilayer steps can be introduced, most of the risks posed by the tainted water can be taken care of by the end of fiscal 2020, says the report, which a panel submitted to the government Tuesday.
The panel, which consists of experts and Tepco and government officials, stresses the need to come up with additional measures in case steps already planned don't work.
