Tokyo, Feb 24: Japanese tech giant Toshiba is considering declaring that its US based nuclear power branch is on the verge of bankruptcy and that the multi million dollar devaluation will result in heavy losses to the company in the near future. 

The Japanese conglomerate has weighed up this move as one of its options in the framework of reviewing the operations of its nuclear unit, which is the root of its financial problems, according to company sources.
 
The news shot up the price of Toshiba shares at the Tokyo Stock Exchange, where they soared to 12 per cent after the drop of more than 4 per cent on Thursday, Efe news reported.
 
The company's shares had lost more than half of its value since it announced in December a multi-million dollar devaluation of its nuclear unit assets in the US, which has led to the reduction of such operations as well as the resignation of its president, Shigenori Shiga.
 
The devaluation of Toshiba's nuclear energy branch is due to the increased costs of labour and construction of the new nuclear plants in the US.
