Bill Gates May Build Small Nuclear Reactor

Hugh Pickens writes "TerraPower, an energy start-up backed by Microsoft co-founder Bill Gates, is in discussions with Toshiba Corp. to develop a small-scale nuclear reactor that would represent a long-term bet to make nuclear power safer and cheaper. Toshiba confirmed it is in preliminary discussions with TerraPower, a unit of Intellectual Ventures, a patent-holding concern partially funded by Gates. Toshiba spokesman Keisuke Ohmori says the two sides are talking about how they could collaborate on nuclear technology, although discussions are still in early stages and that nothing has been decided on investment or development. TerraPower has publicly said its Traveling Wave Reactor could run for decades on depleted uranium without refueling (PDF) or removing spent fuel from the device. The reactor, the company has said, could be safer, cheaper and more socially acceptable than today's reactors. Gates's recent focus on nuclear power has been fueled by an interest in developing new power systems for developing countries where he says that new energy solutions are needed to combat climate change. Terrapower faces a lengthy, multi-year process to get its "traveling wave" reactor concept reviewed by regulators but if TerraPower succeeds in advancing its plans, it could provide an alternative blueprint for the nuclear industry at a time when new reactors may be coming online."

    There's still huge potential for fission power. It's just that civilian reactor technology is basically stuck in the 1970s.

    Notwithstanding Mr. Gates ownership of TerraPower... It makes sense for Toshiba to work with them given (a) Their ownership of the Westinghouse legacy (b) Their experience building large nuclear power reactors (c) Their experience designing small, self contained, fail-safe nuclear reactors in the 100kW to 10MW size range.

      Toshiba was working with NASA to produce a 100kW or 200kW reactor for the proposed lunar base. They had gotten far enough along that they've tested the components using non-nuclear heat sources. It's pretty small but it has very little shielding... You wouldn't want this in your vehicle.

    Well Toshiba bought Westinghouse when the US stopped building nuclear power plants. Rather than letting all that know how go to waste and allowing mindless fear to control their energy policy Japan kept building nuclear power plants.
    GE also builds reactors for the Navy.

  5. Nuclear; Does too little, cost too much by alex_guy_CA · · Score: 3, Informative
    The issues of renewable energy and energy independence have taken center stage in both media and political conversations lately, but the means of achieving various energy goals have proven to be rather controversial. Proposed options dominating news headlines include clean coal, nuclear energy, and offshore drilling. Is there an energy path that we can all agree upon?

    The answer is yes, and Rocky Mountain Institute and Chief Scientist Amory Lovins were featured in a New York Times blog in response to last years Presidential Debate. Energy efficiency, a solution at the core of RMIs work, was discussed as a viable and economically profitable resolution to both energy and economy issues. New York Times writer Kate Galbraith points out that RMI and Amory Lovins have consistently advocated the benefits of a soft-path approach to energy, with efficiency at its core. You can read the article here.

    When it comes to nuclear power specifically, every dollar invested in new US nuclear electricity will save approximately 2-11 times less carbon, and will do so roughly 20-40 times slower, than investing in the same dollar in energy efficiency and micropower (cogeneration plus renewables minus big hydro dams). Buying new nuclear capacity instead of efficiency causes more carbon to be released than spending the same money on new coal plants!

    These conclusions and the empirical evidence supporting them are summarized in Forget Nuclear, and fully documented in The Nuclear Illusion, available for download here, which is to be published in early 2009 by the Royal Swedish Academy of Sciences journal Ambio.

    Hopefully our vision will help put these widely publicized issues into perspective and move us all toward a better understanding that takes us beyond politically divisive issues to collective and viable solutions.
