TOKYO, March 30 (Reuters) - Shares of Tokyo Electric Power slid another 12.7 percent on Wednesday, on top of a 47-year low hit a day earlier as the government pondered whether to nationalise the operator of a stricken nuclear plant.
The shape of a government bail-out is unclear but investors said the huge repair and compensation bills faced by the firm, Asia's largest utility, and reduced income from lost production after this month's earthquake and tsunami were unsustainable.
Tokyo Electric's shares fell as low as 494 yen from Tuesday's close of 566 yen, before recovering a little to trade at 504 yen, down 10.8 percent. (Writing by Rodney Joyce; Editing by Edmund Klamann)
