    Toshia should put their valuable but currently impoverished Nuclear technology unit to the task of coming up with a "backyard" Nuclear Power Station product line, and capitalize on their good fortune to have all the tools to do so.

    That would pull them back up into profitability :)

    Toshiba, buy up these guys and get a foothold in that new burgeoning market!:

    Hyperion Power Generation Inc. Announces Change of Company Name to Gen4 Energy, Inc.

    TECHNOLOGY

    The Gen4 Module is a next generation design that uses a liquid metal cooled, uranium nitride fueled, fast-spectrum reactor that employs control rods for reactivity control. The reactor has been designed to deliver 70 MW of heat (25 MW of electricity) for a 10-year lifetime, without refueling.

    Key advantages of the Gen4 Module design are:
    • Advanced reactor design – Use of advanced reactor concepts provides for a safer and simpler reactor, elimination of many potential accident scenarios that affect LWRs, and elimination of complex reactor systems.
    • Small reactor – A smaller reactor is more appropriately sized for smaller generation requirements, can directly replace existing diesel fueled generators, and requires no upgrade to existing small electricity distribution systems.
    • 10-year power module replacement – The Gen4 Module provides 25 MWe continuously for 10 years on its initial fuel load (compared to an 18 to 24 month cycle for current light water reactors). No on-site refueling is required. After 10 years the entire reactor module is replaced.
    • Underground containment vault – The reactor is sited in an underground containment vault to provide isolation from the environment, prevent intrusion or tampering, and avoid harm from natural disasters.
    • Factory-assembled transportable power modules – Factory assembly allows for standard designs, superior quality control, and faster construction and on-site deployment.
    A standardized design will offer several advantages:
    • Manufacturing process controls will be uniform and will not vary between units.
    • Nuclear fabrication and assembly will be completed at the factory before the unit is shipped, minimizing the nuclear construction capabilities that are necessary on site.
    • On site construction activities will be limited to the reactor vault, the non-nuclear systems, placement of the Gen4 Module in the vault, and connection to the Gen4 Module to non-nuclear systems and controls. This will significantly reduce the on-site construction complexity and result in a faster construction schedule.
    • Gen4 Energy will provide standard operating procedures, operator training, licensing support, technical support, in-service engineering, and safety analysis, significantly reducing the nuclear expertise and staffing that is required of the owner/operator.
    Key material selections include:
    • Lead Bismuth Eutectic (LBE) coolant -The core coolant is LBE, which is non-reactive to air and water, with a mixed mean exit temperature of 500C. A solid phase oxygen control system is used to control the oxygen level in the coolant to maintain a protective coating on structural surfaces, limiting corrosion.
    • Uranium Nitride (UN) fuel- The fuel consists of 19.75% enriched (non weapons grade) UN pellets contained in clad tubes made of HT-9. These high-temperature ceramic material pellets deter the ability to separate plutonium from spent fuel.
    • Stainless Steel structural materials (HT-9 and T-91)
    • Quartz radial reflector
    • B4C control rods for reactivity control -There are three independent reactivity shut-down systems in the core: a shutdown rod system composed of six boron carbide (B4C) rods, a control rod system comprising 12 boron carbide (B4C) rods and a reserve shutdown system consisting of a central cavity into which B4C balls may be inserted. Each of the three systems can independently take the core to long-term cold shutdown. The rod shutdown and the ball shutdown systems perform this safety function automatically and instantaneously when triggered.

    You should warn people before making a left turn that quick.

    Came for the laptop company, stayed for the nuclear power plans.

    It's not about the laptops at all :confused::eek:o_O

    Follow the OP link and read the article, Toshiba's whole financial failure mode is due to their Westinghouse US Nuclear Power plant investments - financially nuking them ;)

    Toshiba’s bid for survival
    "Toshiba Corp., the embattled electronics and machinery giant once deemed a blue-chip company representative of Japan Inc., is seeking to survive the latest crisis derived from huge losses in its nuclear power business in the United States"
    http://www.japantimes.co.jp/opinion/2017/04/14/editorials/toshibas-bid-survival/#.WPJ5nke1tFE

    This is why I post the title and snippet of interest to inform my posts when providing links... it may seem like too much info, but not enough info is far worse... few follow the link, instead fancifully filling in their own motives and interests, and bang zoom, it's all about "laptops" ;)

    Nope. Notebook 7 line, Notebook 9 line, and TabPro S all run Windows. Maybe some others I'm forgetting too.

    Good news, Toshiba is already in that mini "neighborhood" nuclear plant market like Hyperion:

    Toshiba 4S
    https://en.wikipedia.org/wiki/Toshiba_4S

    "The Toshiba 4S (Ultra super safe, Small and Simple) is a micro sodium reactor design.

    The plant design is offered by a partnership that includes Toshiba and the Central Research Institute of Electric Power Industry (CRIEPI) of Japan.[1]

    The technical specifications of the 4S reactor are unique in the nuclear industry.[2] The actual reactor would be located in a sealed, cylindrical vault 30 m (98 ft) underground, while the building above ground would be 22×16×11 m (72×52.5×36 ft) in size. This power plant is designed to provide 10megawatts of electrical power with a 50 MW version available in the future.[3]

    The 4S is a fast neutron sodium reactor. It uses neutron reflector panels around the perimeter to maintain neutron density. These reflector panels replace complicated control rods, yet keep the ability to shut down the nuclear reaction in case of an emergency. Additionally, the Toshiba 4S utilizesliquid sodium as a coolant, allowing the reactor to operate 200 degrees hotter than if it used water. [clarification needed] Although water would readily boil at these temperatures, sodium remains a liquid; the sodium coolant therefore exerts very low pressure on the reactor vessel even at extremely high temperatures.[citation needed]

    The Toshiba 4S Nuclear Battery was proposed as the power source for the Galena Nuclear Power Plant in Alaska, but the project was abandoned and Toshiba did not proceed with an application for certification of the design.[4]"

    You know what? I think the thread actually ended up being far more interesting this way for a multitude of reasons ;) Hence why I didn't bother correcting the misconception :D:p
