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…
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…
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…
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…
The Army Nuclear Power program recognized the potential benefits of putting a nuclear power plant on a water mobile platform in the early 1960s. In January, 1963, construction began on the Sturgis, a World War II vintage Liberty ship hull modified to accept installation of a 10,000 kilowatt pressurized water nuclear steam plant. Designated the…
Most people associated with the nuclear industry, and many residents of Florida have some knowledge of the ill-fated Westinghouse/Newport News Offshore Power System project. Begun in 1970, this project was based on two ideas. The first was that a series of identical reactors produced in a factory type setting could be completed in a shorter…
The SL-1 accident was initiated by the rapid withdrawal of the central control rod. Starting from a fully shutdown condition, the action produced a condition in the core technically known as a prompt criticality. When the SL-1 reactor achieved prompt criticality, a number of events happened in rapid succession. The core power level pulsed to…
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….
Some of the sources that we interviewed suggested that there may have been unstated reasons for not releasing the report. While the term “cover-up” was not used, the phrase “let sleeping dogs lie” was used more than once. One common link in the training of most nukes is the viewing of a grainy, black and…
The root cause of the accident is well understood. Investigators found the central control rod lying across the top of the reactor vessel. All the other rods were clamped in their fully inserted positions. (Note from the editor: The following story is conjecture supported by interviews of first hand sources and a careful review of…
At 9:01 pm on January 3, 1961, the first indication of trouble at SL-1 was received at Atomic Energy Commission Fire Stations. The alarm, which was triggered by one of several measured parameters at the plant, was immediately broadcast over all National Reactor Testing Station radio networks. By 9:10 pm, fire trucks and security personnel…
In the period from 1966 to 1964, there were two basic reactor choices being offered for commercial electric power production. American companies were offering reactors that used ordinary water under pressure as the reactor coolant. British and French companies were offering reactors using pressurized CO2 gas as the reactor coolant. There were substantial technical differences…
