A nuclear waste disposal facility being used to store radioactive water from the crippled Fukushima No. 1 power plant will soon be full, Tokyo Electric Power Co. officials said Monday.

The operator, known as Tepco, plans to suspend the extraction operation until mid-June once the facility becomes filled and until a new water treatment facility begins operating.

A temporary storage tank is being prepared but will not be ready until around early July, the officials said.
