Small Nuclear Power Plants

  • Valuable Tool for Antarctic Research or Costly Waste?

    Before the discovery of nuclear fission, the only power source capable of supplying reliable electrical energy in remote locations was a combustion engine. Because of its compact nature compared to a coal fired steam engine, the internal combustion engine was the power system of choice. When engineers realized that a fission power plant could operate…

  • A Question of Economics: The Answer Depends on the Assumptions

    In 1970, President Nixon affirmed that the United States had long term objectives in the Antarctic regions and consolidated responsibility for management and funding of all Antarctic operations under the National Science Foundation. According to the new arrangement, the NSF was to take over the funding of PM-3A as of July 1, 1972. At the…

  • How Clean is Clean? Blasting Out Frozen Soil

    The final disposition of the soil was to spread it out on the ground and cover it with asphalt, turning the expensively gathered Anarctic soil into a parking lot that continues to serve the sailors at Port Hueneme, California. After the decision was made to decommission the PM-3A, the Naval Nuclear Power Unit began planning…

  • Letter from the Editor: PM-3A, Pioneer in Anarctic Research

    Recently I took my family to the Tampa, Florida Museum of Science and Industry (MOSI), which had a traveling exhibit on Antarctica. The display included a great deal of information about the dedicated explorers and unique wildlife indigenous to that remote land with one of the harshest climates on earth. Several of the exploration groups…

  • PM-3A Design and Construction: Rapid Pace to Fulfill a Need

    Between January 1 and March 1, 1962, the plant was assembled by a team of contractors and military technicians. On March 4, 1962, the plant reached initial criticality. The U. S. Navy began intensive involvement in Antarctic research missions during 1955 in preparation for the International Geophysical Year. The Department of Defense assigned the Navy…

  • New Nuclear Power Barges: Russians Build on Ice Breaker Lead

    The northern coast of Russia is an area endowed with rich natural resources and vast mineral wealth but burdened with a limited infrastructure. Because of the extremely cold winters, transportation is difficult and infrequent. During the Soviet era, finding workers to exploit the riches was not difficult; they had little choice in the matter. Once…

  • SL-1: Designed for Remote Power and Heat

    SL-1’s mission was to provide power to radar stations along the northern perimeter of North America; a series of such stations was known as the DEW (Defense Early Warning) Line. The Army’s designation , SL-1, tells us that the plant was a stationary, low power reactor, and that it was the first of its kind….

  • Keep it Simple: Complex Systems Cost More

    It must also be understood that the 60 percent efficient gas turbine combined cycle is a very sophisticated piece of machinery operating with its material at close to maximum limits. A first generation Adams Engine might achieve a thermal efficiency of approximately 30-35 percent, instead of the 55-60 percent that is currently being advertised for…

  • Letter from the Editor: Small Is Beautiful

    At the request of several readers, we have decided to dedicate this issue to discussing the Adams Engine concept. Rather than talking about technical details, however, we have decided to talk about general principles and philosophies. Adams Atomic Engines, Inc. has determined that it is possible to build uranium heated machines that can fulfill many…

  • Prefab Reactors For Off-Grid Users

    At the top of Mt. Washington, New Hampshire, for example, electricity for the weather station is provided by a diesel generator using fuel that must be moved by small tanker trucks struggling up a very steep grade. The Army Nuclear Power Program was established as part of the Atomic Energy Commission in 1954. It was…

  • Army Nuclear Power Plants

    Designation Description of Reactors SM-1 This stationary military reactor was the Army’s prototype and training facility. It began operation in April 1957 at Fort Belvoir, VA, several months before the Shippingport reactor. SM-1 has the distinction of having been the first nuclear power plant to be hooked to an electrical grid. 2,000 kw. SM-1A Built…

  • Letter from the Editor: Portable Nuclear Reactors

    The United States Army ran an innovative nuclear power program for more than 20 years. The men involved operated a series of small, nuclear heated generating plants in some of the world’s least hospitable environments. The story of what those diligent heros did has been all but lost. Though the Army was the lead service…
