Toshiba's Westinghouse troubles
Nuclear services businesses run by Westinghouse contributes to one-thirds of Toshiba's total revenue.
The dispute surfaced when Toshiba, in December 2016, alerted its investors on heavy losses suffered in deals involving Westinghouse. By February, losses were revealed to be about $6.3 billion.
Although Toshiba unsuccessfully tried to sell majority stakes in Westinghouse and was allowed to delay reporting earnings, it could not avert bankruptcy.

Toshiba might look to its memory chip unit (valued between $9 billion and $13 billion) to secure funds. It is also set to sell majority stake within its NAND flash memory unit.
The future of nuclear power
Westinghouse's bankruptcy indicates a decreasing preference for nuclear power due to high costs among other reasons. The projects further suffer delays mainly due to dearth of skilled workers to meet regulatory standards.
Toshiba has clarified that its operations in Asia, Africa and UK would be untouched by the bankruptcy. Its projects including those in India are likely to be delayed.
Will India get its Westinghouse reactors?
Following the Indo-US civil nuclear deal, Westinghouse made an arrangement with India to set up 6 of its renowned AP1000 reactors in Andhra Pradesh by June 2017. A statement from US embassy following the bankruptcy, noted the reactors would provide 60 million Indians with power.
