    • Advanced gas cooled designs
    • Factory provided, assembled on-site
  • DoD energy needs are increasing as available fossil fuels increase in cost and decrease in availability
  • Hundreds of small nuclear reactors have been built, mostly for naval use and as neutron sources
  • National Security requirement for independent power supply for DoD bases
    • Multiple small reactors could either be distributed or clustered to solve energy demand
    • Could be part of a Sandia National Laboratory micro grid concept
  • Characteristics of smaller nuclear reactors:
    • Greater simplicity of design
    • Economy of mass production
    • Reduce cost of site
    • High level of passive/inherent safety

    • Started by Kevin Billings, Assistant Secretary AF for energy, environment, saftey and occupational health (MAR 08)
      • Senator Larry Craig (ID) sent letter to SAF asking if AF was interested
      • Senator Pete Domenici (NM) sent a similar letter
three branches three reactor programs
Naval Reactor efforts began in the late 1940s with Rickover’s pursuit of a nuclear reactor for a submarines, culminating in the launch of the USS Nautilus in 1954.

Pressurized water reactor technologies were chosen based on their compactness and relative simplicity.

The Air Force also had a desire for a nuclear-powered aircraft that would serve as a long-range bomber.

An aircraft reactor was far more challenging than a terrestrial reactor because of the importance of high-temperatures, light weight, and simplicity of operation.

The Nuclear Aircraft Program led to revolutionary reactor designs, one of which was the liquid-fluoride reactor.

The Army Reactor Program began in 1953 to enable nuclear power for remote sites—they chose PWR technology because the Navy did.

Reactors for Ft. Belvoir, Ft. Greely, Camp Century, and other sites were built.

Three Branches—Three Reactor Programs

Army Nuclear Power Program

MA-IA Reactor

  • Key to the codes:
    • First letter: S - stationary, M - mobile, P - portable.
    • Second letter: H - high power, M - medium power, L - low power.
    • Digit: Sequence number.
    • Third letter: A indicates field installation.

The Army Nuclear Power Program (ANPP) was a program of the United States Army to develop small pressurized water and boiling water nuclear power reactors for use in remote sites.

Eight reactors were built in all: (Of the 8 built, 6 produced operationally useful power for an extended period)

  • SM-1, 2 MWe. Fort Belvoir, VA, first criticality 1957 (several months before the Shippingport Reactor) and the first U.S. nuclear power plant to be connected to an electrical grid.
  • SM-1A, 2 MWe, plus heating. Fort Greely, Alaska. First criticality 1962.
  • PM-2A, 2 MWe, plus heating. Camp Century, Greenland. First criticality 1961.
  • PM-1, 1.25 MWe, plus heating. Sundance, Wyoming. Owned by the Air Force, used to power a radar station. First criticality 1962.
  • PM-3A, 1.75 MWe, plus heating. McMurdo Station, Antarctica. Owned by the Navy. First criticality 1962, decommissioned 1972.
  • SL-1, BWR, 200kWe, plus heating. Idaho Reactor Testing Station. First criticality 1958. Site of the only fatal accident at a US nuclear power reactor, on January 3 1961, which destroyed the reactor.
  • ML-1, first closed cycle gas turbine. Designed for 300 kW, but only achieved 140 kW. Operated for only a few hundred hours of testing before being shut down in 1963.
  • MH-1A, 10 MWe, plus fresh water supply to the adjacent base. Mounted on the Sturgis, a barge converted from a Liberty ship, and moored in the Panama Canal Zone. Installed 1968, removed on cessation of US zone ownership in 1975 (the last of the eight to permanently cease operation).

  • Combat Logistics – “Tooth to tail” ratio > 10-1
  • Extended (and vulnerable) supply lines
  • Prohibitive transportation costs – Fuel costs $100-600/gallon
  • Storage and distribution challenges – Large infrastructure costs
  • No, or inadequate local sources
  • Combat Losses
  • -- Men and material
  • -- Impact on Combat operations
  • Fuel Consumption per soldier is rapidly increasing

What Future Vessels Must Provide

  • “Four themes hardware producers need to accommodate
  • Systems must be capable of supporting the transformation mission
    • LCS – shallow water; High speed
    • Advanced weapons and sensors
  • Reduced manning is vital
    • As personnel costs drive total cost, value of reducing crew size achieves similar importance to acquisition system cost reduction
  • Logistics must be simplified
    • Common elements, reduced numbers of models/series
    • De-salinated water and other products
  • Open Architecture is paramount
    • Allows rapid upgrade of systems to the latest technologies
    • Allow for continuing competition of the best ideas/capabilities”
  • Donald C. Winter, Secretary of the Navy, remarks to Bear Sterns Defense and Aerospace Conference, 31 May 2006, Ritz Carlton, Arlington, VA
  • LFTR successfully addresses each
  • Scaleable to fit LCS and other ships
  • Power for EM Guns/sensors
  • Global range at flank speed
  • Simplicity & safety reduces operations manpower, increases flexibility which further reduces crew size
  • LFTR reduces ship fire and damage control crews
