Japan's industry ministry has launched an expert team to study disposal of highly radioactive waste from nuclear power plants. The study includes as potential candidate sites areas beneath the coastal seabed.
A ministry panel last month compiled an interim report on conditions of disposal sites for such waste made of residual liquid from reprocessed spent fuel.
The report suggested areas within 20 kilometers of coasts as appropriate disposal sites, saying their proximity to ports makes them safe for nuclear waste transport.
The ministry set up the team to carry out a geological survey of coastal areas.
At its meeting on Tuesday, officials from the Nuclear Waste Management Organization showed a picture of how tunnels from coastal areas or a nearby island would connect disposal sites built under the seabed.
They said groundwater flows slowly beneath the seabed, and that such disposal sites are unaffected by sea level changes and have security advantages.
The team is to study technical issues such as geological features and seawater impact before compiling a report by around the middle of this year.
