A company backed by Microsoft founder Bill Gates and Toshiba are in early talks to jointly develop a small nuclear reactor, the Japanese electronics giant said yesterday.
The Nikkei Shimbun earlier reported that the two sides would team up to develop a compact next-generation reactor that can operate for up to 100 years without refueling to provide emission-free energy.
The business daily said the joint development would focus on the Traveling-Wave Reactor (TWR), which consumes depleted uranium as fuel.
Current light-water reactors require refueling every few years.
“Toshiba has entered into preliminary talks with TerraPower,” Toshiba spokesman Keisuke Ohmori said. “We are looking into the possibility of working together.”
Gates, 54, is the principal owner of TerraPower, an expert team based in the US state of Washington that is investigating ways to improve emission-free energy supplies using small nuclear reactors.
Unlike the current reactors at mega power plants, the smaller types could be introduced by cities or states or in developing countries more easily.
Ohmori said Gates, together with other TerraPower executives, had visited a Toshiba laboratory for nuclear power research near Tokyo last year.
“TerraPower is developing a small nuclear reactor and Toshiba is developing a different kind of small reactor. They were interested in Toshiba’s technology and aiming at practical realization” of small reactors, Ohmori said.
He said the two sides had just begun to “exchange information” but stressed that “nothing concrete has been decided on development or investment.”
Gates is expected to use his enormous personal wealth to support the development of TWRs and his investment could reach several billion dollars, the Nikkei said.
The news boosted Toshiba’s share price by about 4 percent yesterday.
The Nikkei said TerraPower had decided to join forces with Toshiba as it lacks the know-how to manufacture nuclear power equipment.
Toshiba, which owns US nuclear plant maker Westinghouse, has developed a design for an ultracompact reactor that can operate continuously for 30 years.
The company is preparing to apply for US approval to start constructing the first such reactor as early as 2014 and put it into practical use by the end of the decade, Ohmori said.
The Investment Commission yesterday approved a Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) application to invest an additional US$3.5 billion in its Arizona subsidiary to manufactured advanced chips. The world’s largest contract chipmaker’s board of directors last month approved the funding project after TSMC started moving manufacturing equipment into the fab in December last year in preparation for the production of 4-nanometer chips next year. TSMC said it has also commenced the second phase of facility construction in Arizona. The second fab is to produce semiconductors using 3-nanometer technology in 2026. Altogether, TSMC plans to spend US$40 billion on the Arizona fabs, doubling its
KEY SECTOR: Taiwan’s new chip legislation is insufficient, and a more strategic ‘chip act’ that covers the whole semiconductor ecosystem is needed, MediaTek’s chairman said MediaTek Inc (聯發科) chairman Rick Tsai (蔡明介) yesterday urged the government to formulate a state semiconductor strategy and comprehensive “chip act” that includes local chip designers and smaller-scale semiconductor companies, as they are facing intensifying competition from China. The government is playing an increasingly important role in safeguarding the local semiconductor industry’s competitiveness, given that the US, the EU and Japan are offering hefty subsidies and significant tax incentives to build semiconductor capacity domestically, as they have realized the strategic importance of semiconductors, Tsai said. To implement such a program, the government should take steps to finance a “chip act,” Tsai said
Microsoft Corp has threatened to cut off access to its Internet search data, which it licenses to rival search engines, if they do not stop using it as the basis for their own artificial intelligence (AI) chat products, people familiar with the dispute have said. The software maker licenses the data in its Bing search index — a map of the Internet that can be quickly scanned in real time — to other companies that offer Web search, such as Apollo Global Management Inc’s Yahoo and DuckDuckGo. Last month, Microsoft integrated a cousin of ChatGPT, OpenAI’s AI-powered chat technology, into Bing. Rivals
Three years after Luxembourg declared all public transport free in a bid to clear its roads of jams and cut pollution, the car is still king of the congested grand duchy. Traffic permitting, it is barely an hour’s drive from Weiswampach in the far north of Luxembourg near the German and Belgian borders to Dudelange in the south, next door to France. The wealthy country of just 650,000 people appeared the perfect place for a bold experiment — making public transport on trains, trams and buses free nationwide. However, Luxembourg, despite its lack of long-distance highways, has one of the highest rates
