Jan 4 (Reuters) - A group of investors led by Brookfield Business Partners LP said on Thursday it would buy bankrupt nuclear services firm Westinghouse Electric Co from Toshiba Corp for about $4.6 billion.
Westinghouse filed for bankruptcy in March after two nuclear power plants it had designed and was constructing in the U.S. Southeast had gone billions of dollars over their fixed-cost contracts.
The deal is expected to close in the third quarter of 2018.
