Toshiba, Gates to work on next-gen nuclear reactor

Microsoft founder Bill Gates and Japanese electronics giant Toshiba Corp. are discussing the possibility of jointly developing a cheaper next-generation nuclear reactor that can operate for up to 100 years without refueling, company officials said on Tuesday.

Toshiba Corp. will study cooperating with US venture firm TerraPower, funded by Microsoft Corporation chairman Gates, to jointly develop traveling-wave reactor that can function up to 100 years without refueling, they said.

Gates is said to be considering investing personal assets worth several hundreds of billions of yen in developing the new type of reactor.

The officials said Toshiba and TerraPower have begun exchanging information in a move that would bring together Gates' ample wealth and the know-how and experience which the Japanese electronics giant has established in the nuclear power business, Kyodo news agency reported.

While it is likely to take more than a decade to put the next-generation reactors to practical use, the TWRs can save operating costs because they do not require refueling and are expected to draw demand in emerging countries.

The new reactors, which consume depleted uranium as fuel, can operate from 50 to 100 years and are considered relatively safer than conventional boiling water reactors, which need periodic refueling.

Toshiba, which acquired Westinghouse Electric Co. of the United States, is currently developing an ultracompact nuclear reactor, called the Super-Safe, Small and Simple, or 4S, which can operate continuously for up to 30 years.

The 4S technology is believed to be applicable with the TWRs because they have many aspects in common, according to the officials.

Gates, who has recently been focusing on global warming and other climate issues, effectively owns TerraPower and proposed the collaboration with Toshiba, the report said.
