TEPCO now freezing the last section of Fukushima nuclear site’s underground wall

Daily Mail 22nd Aug 2017, The Fukushima nuclear plant’s operator Tuesday started freezing the last
section of a $320 million ice wall designed to cut down on vast amounts of
contaminated water at the site of the worst atomic accident in a
generation.

Tokyo Electric Power (TEPCO) began pumping coolant into the
remaining seven metres (23 feet) of its 1.5-kilometre underground wall
which encircles four reactors along Japan’s northeast coast. Underground
pipes circulate the coolant and freeze soil around the buildings. The
30-metre deep wall is designed to block underground water from nearby
mountains from flowing into the shattered complex and then seeping into the
Pacific.

It is reportedly expected to take more than two months until the
wall is completely frozen. The huge utility has been building the barrier
since March 2016 with the government picking up its 34.5 billion yen ($320
million) price tag. Even now, with the ice wall almost complete, about 140
tonnes of underground water flows into the plant daily, forcing the company
to pump it out and store it in on-site tanks.

“When the ice wall is completed, we estimate that the amount of underground water flowing into
the complex will be less than 100 tonnes,” a company spokesman said. But
some experts have cast doubt on the ice wall’s effectiveness in containing
the problem.  http://www.dailymail.co.uk/wires/afp/article-4811494/Fukushima-reactor-ice-wall-nearly-finished.html
