POWER FOR CONTINENT SEVEN - US Navy , McMurdo Station , PM-3A 40110 2595

This fascinating film was made by the U.S. Department of Energy / Atomic Energy Commission and the U.S. Navy in 1962. In that year, the U.S. Navy delivered a nuclear reactor to Antarctica to power the McMurdo Station. The plant, like nearby Scott's Discovery Hut, was prefabricated in modules. Engineers designed the components to weigh no more than 30,000 pounds (13,608 kg) each and to measure no more than 8 ft 8 inches by 8 ft 8 inches by thirty feet. A single core no larger than an oil drum served as the heart of the nuclear reactor. These size and weight restrictions were intended to allow the reactor to be delivered in an LC-130 Hercules aircraft. However, the components were actually delivered by ship. The reactor generated 1.8 MW of electrical power and reportedly replaced the need for 1,500 US gallons (5,700 L) of oil daily. Engineers applied the reactor's power, for instance, in producing steam for the salt water distillation plant. The reactor, designated PM-3A, was designed and built by the Martin Company. There were problems with the plant from the beginning. It underperformed to expectations and frequently fell victim to power failures. It also raised concerns in New Zealand, where U.S. Navy ships transporting the fuel and waste under Operation Deep Freeze would dock for a few days while in transit. All of these factors led to PM-3A existing on very shaky ground almost from the day it began operating. The coup de grace, however, came in 1972 when a leak in the reactor's pressure vessel was discovered during a routine inspection. A closer look uncovered cracks throughout the reactor, caused by failures in some of the welds, and the decision was made to close and dismantle PM-3A. Disposal presented other headaches. Decommissioned nuclear plants are usually entombed in concrete, but provisions in the Antarctic Treaty made this impossible, so the dismantled plant, along with some of the contaminated ground surrounding it, was shipped to a disposal site in California.
