Japan considering building network of tunnels beneath seabed to store thousands of tonnes of nuclear waste
Government agencies are discussing the plan as a ‘long-term solution’ while environmentalists have dismissed it as an expensive ‘pipe dream’.
A team of experts from Japan’s Nuclear Waste Management Organisation is examining the possibility of storing thousands of tonnes of highly radioactive nuclear waste in tunnels deep beneath the Pacific Ocean.
Japan already has a stockpile of some 40,000 units of vitrified nuclear waste, with each of the stainless steel containers containing around 500kg of radioactive material, with more waste being produced.
Two of Japan’s 55 nuclear reactors resumed operations last year, after their operations were subjected to detailed scrutiny as a result of the disaster at the Fukushima nuclear plant, caused by the 2011 earthquake and tsunami.
A number of additional reactors have applied to restart operations, while dozens of the older plants will now have to be decommissioned as they have reached the end of their operational lives. Japan has never before decommissioned a reactor and does not have a dedicated storage facility for high-level nuclear waste.
We are looking for a long-term solution to the issue that also meets the terms of the law on the storage of high-level waste
“We are presently looking for a site and one of the options being considered is for tunnels beneath the seabed,” Kenichi Kaku, a spokesman for the agency, told the South China Morning Post.
“We are looking for a long-term solution to the issue that also meets the terms of the law on the storage of high-level waste,” Kaku explained.
