Westinghouse Electric, the U.S. nuclear unit of embattled Japanese electronics giant Toshiba, has been acquired in a deal valued at about out $4.6 billion.

Westinghouse Electric Co. declared bankruptcy protection early last year, leaving a number of nuclear projects in limbo.

The acquisition by Brookfield Business Partners LP on Thursday comes one day after an agreement tying up loose ends from two failed nuclear reactors in South Carolina.
