Voici la question qui me guide dans mes recherches...

L’appât du gain manifesté par les entreprises supranationales et certains groupes oligarchiques, de même que le contrôle des ressources naturelles par ceux-ci, dirigent l’humanité vers un nouvel ordre mondial de type féodal, voir même sa perte. Confronté à cette situation, l’être humain est invité à refuser d’accepter d’emblée une pseudo-vérité véhiculée par des médias peut-être à la solde de ces entreprises et groupes. Au contraire, il est invité à s’engager dans un processus de discernement et conscientisation afin de créer sa propre vérité par la confrontation de sa réalité nécessairement subjective à des données objectives, telles que révélées par la science, par exemple.

Building a modular nuclear power plant in a 11 weeks!

Looking at what we accomplish in the 1960's, we wonder why today it takes 10 years and billions to build a nuclear power plant?

In seventy-seven days, the Army team assembled the prefabricated reactor. Just nine hours after fuel elements containing forty-three pounds of enriched Uranium-235 were inserted into the reactor, electricity was produced.

The US Army Nuclear Power Program was created to develop small nuclear power reactors for use at remote sites. Most were based on existing US Naval reactor designs. Eight reactors were built in all, and six of the eight produced useful power. The nuclear reactor at Camp Century was the first of the US Army's portable reactors to actually produce power.

The portable nuclear power plant at Camp Century was designated PM-2A. Its designation indicates: “P” for Portable; “M” for Medium Power; “2” for the sequence number; and the letter “A” indicates field installation. The PM-2A was rated two megawatts for electrical power and also supplied steam to operate the water well. The PM-2A was built by Alco Products, Inc. of Schenectady, New York. The USNS Marine Fiddler transported the reactor from Buffalo, New York to Thule Air Base in Greenland, arriving on July 10, 1960. Up to this time, it was the most valuable cargo ever shipped out of the port of Buffalo. In addition, the Army flew one of the three blast coolers to Thule on a C-124 Globemaster to demonstrate the practicality of air transport. Four hundred tons of pipes, machinery, and components were then carefully transported over the ice in twenty-seven packages. Special care was taken not to damage the parts, since intensely cold metal can become dangerously brittle. As a credit to superb packaging, a ceramic top to a lab cabinet was the only item damaged during transport.

In seventy-seven days, the Army team assembled the prefabricated reactor. Just nine hours after fuel elements containing forty-three pounds of enriched Uranium-235 were inserted into the reactor, electricity was produced. It was soon discovered that additional shielding would be necessary. This shielding was accomplished by adding a layer of two inch thick lead bricks to the primary shield tank. Except for downtime for routine maintenance and repairs, the reactor operated for thirty-three months, until July 9, 1963, when it was deactivated pending a decision to remove it. This decision stemmed from plans to discontinue year-round operations at Camp Century to reduce costs. In addition, the tunnel support structure sheltering the reactor was suffering from reoccurring damage due to compacting snow. A conventional diesel powered plant would have consumed over one million gallons of fuel over the same period. While the power plant was designed to provide 1560 kilowatts of power, Camp Century's power needs peaked at 500 kilowatts, and gradually declined from there. During the reactors operational life, a total of 47,078 gallons of radioactive liquid waste was discharged into the icecap. The PM-2A was removed in the summer of 1964 by the 46th Engineers based at Fort Polk, Louisiana. No military service was willing to accept the plant at another location so the PM-2A's components were put into storage. The reactor vessel was subjected to destructive testing in order to study neutron embrittlement of carbon steel. Phillips Petroleum Company conducted the testing for the US Atomic Energy Commission in 1966. After extreme testing, it was found to be much more durable than expected. Failure of the vessel finally occurred at minus twenty degrees Fahrenheit and 4,475 pounds per square inch pressure after hydrochloric acid was added to a machined defect.
