Japan’s Ministry of Environment plans an interim storage site of approximately 16sqkm to temporarily house contaminated soil and other waste. Some 22 million cubic metres of soil is likely to be collected. Scattered throughout Fukushima prefecture are some 5.5mn black bags containing soil contaminated by the crippled reactors. The government intends to find a final disposal site outside Fukushima Prefecture to permanently store the contaminated soil by 2045.
One million tonnes of contaminated radioactive water is being stored in 850 5-storey tanks. The amount of contaminated water is growing by 150 tonnes a day. Capacity is 1.1mn tonnes. The Nuclear Regulation Authority (NRA) is encouraging Tepco to dump water that has diluted to levels below that of national standards into the sea claiming it will have little or no impact on local fisheries. The NRA has said that these tanks can’t be used indefinitely, planning to store it until January 2021.
Tepco aims to remove to remove melted fuel debris inside the damaged reactors around 2021 and remove spent and unused fuel rods from the storage pools inside reactor 3 in the middle of this year. The other two reactors will see their rods removed around 2023.
Unsurprisingly information is scant leading to public mistrust of foodstuffs emanating from the region. Taxpayers have funded around $120bn so far in the clean up. To think much of this damage could have been avoided had then PM Kan listened to his nuclear experts to release the pressure from the reactors 10 hours before they exploded.
