Letter from the Editor: A History of Success

The United States Navy submarine reactor program has a record of achievement and respect dating back to the early 1950s. In a field full of failed projects begun with high expectations, the Naval Reactors program is worthy of admiration and study. In this issue of AEI, we will focus on several early technical decisions that…

Pressurized Water: Best Choice for the 1950s Subs

When Rickover first began studying nuclear technology, he found a program in severe disarray. The Army’s Manhattan Project had accomplished its mission of completing a workable bomb before the end of the war. Many of the key scientists and engineers had left the program, eager to leave the security restrictions and poor working conditions behind….

In the news: November 1995

Russian Delegation Visits Cuba (October 10, 1995) Russian scientists and businessmen visited Cuba to discuss the future of the VVER-440 pressurized water reactor at Juragua. According to an official at Cuba’s National Center for Nuclear Security, construction was halted when the reactor was 90 percent complete. Cuba’s government is investigating the possibility of completing the…

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…

Letter from the Editor: Breeding Better Reactors

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…

Plutonium Fuel Cycle: Under Attack

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…

Liquid Metal Fast Breeder: Right Answer, Wrong Question

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…

Light Water Breeder Reactor: Adapting A Proven System

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…

In the news: September 1995

Modern Hiroshima Described (August 7, 1995) (Knight-Ridder Newspapers) “This was supposed to have become a dead city, a toxic landscape so contaminated by radiation that nothing green would grow for generations. A nuclear desert – that’s what even some scientists saw in Hiroshima’s future. Instead, today’s Hiroshima is a thriving, flower-planted, ultramodern metropolis of 1-million…

Rocket Technology Applications: Machines With Limitless Capabilities

Under any circumstances, there is a very limited market for nuclear rockets. Even if space exploration is raised in the national priority list, the first mission to Mars would probably occur in about 2010. For at least a decade or more after that, trips would probably be infrequent at best. There would be some utility…
