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…
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…
Conventional wisdom holds that a breeder reactor produces more fuel than it uses. This idea is fascinating to some, but confusing to a whole group of rational people. It sounds too much like science fiction or Madison Avenue hype. Actually, a breeder reactor is not magic, but it is a marketing exaggeration to state that…
AEI would prefer to concentrate its efforts on discussing the incredible technical potential of nuclear energy while leaving the discussion of politics and personality to others. When trying to understand nuclear energy technical decisions, however, it is essential to understand some of the political issues involved. For the last 20 years, there has been an…
Soon after the development of the first nuclear reactors, scientists and engineers began to discuss the possibility of a nuclear fuel shortage. As far as these nuclear pioneers knew, there was a rather limited supply of uranium that was concentrated in certain areas of Africa and Eastern Europe. The situation was considered even more critical…
At 12:30 am, on August 26, 1977, the operators at the Shippingport Atomic Power Station began lifting the central modules of the experimental breeder reactor core into the blanket section. At 04:38 am, the reactor reached criticality. During the next five years, the core produced more than 10 billion kilowatt-hours of thermal power – equivalent…
The Japanese nuclear ship Mutsu is designed not for show, but for research. She is currently being used by the Japan Atomic Energy Research Institute (JAERI) as a test bed to validate computer models of the behavior of pressurized water reactors in an ocean environment. The Mutsu has a 10,000 shaft horsepower nuclear engine. The…
One of the main reasons for publishing this letter is to add a healthy dose of reality to the mythology that has surrounded the atomic energy field. There are so many of these myths that this column will be a regular feature of the Atomic Energy Insights. One of the most prevalent myths is that…
Atomic energy provides an amazing source of concentrated power. The potential applications that have been proposed are widely varied. There is room for unlimited innovation and creativity. Imagine what it would be like to have a battery that could provide power for several decades without recharging. Sounds almost like science fiction. Fact, in this case,…
On December 2, 1942, Enrico Fermi and a small band of scientists and engineers demonstrated that a simple construction of graphite bricks and uranium lumps could produce controlled heat. Let’s look back to see how simple that first reactor was. Behind the Scenes The space chosen for the reactor was a squash court under the…
