TOKYO (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.
