TOKYO, Nov 26 (Reuters) - Tokyo Electric Power Co (Tepco)
will launch remedial works at the stricken Fukushima
Daiichi nuclear plant to strengthen an ice wall intended to halt
the flow of groundwater after testing indicated partial melting.
The work could begin as early as the start of December,
according to a presentation from the plant operator dated
Thursday, part of a costly and troubled effort to secure the
site following the 2011 earthquake and tsunami.
The ice wall is intended to limit the seepage of groundwater
into the plant, which has created large amounts of toxic water
being stored by Tepco in tanks.
Japan plans to release https://www.reuters.com/article/disaster-fukushima-water-release-idTRNIKBN2HQ0FT
more than 1 million tonnes of water into the sea after treating
it. The water contains the radioactive isotope tritium, which
cannot be removed.
