PPT : Nuclear Power Today
Content Inside :
Early Beginnings
* Atomic Energy Commission (AEC) established by Congress in 1946 as part of the Atomic Energy Act
* AEC authorized the construction of Experimental Breeder Reactor I ( EBR-1) at a site in Idaho in 1949
* in August of 1951, criticality (a controlled, self-sustained, chain reaction) was reached using uranium
* A football sized core was created and kept at low power for four months until December 20, 1951
* power was gradually increased until the first usable amount of electricity was generated, lighting four light bulbs and introducing nuclear generated power for the first time
* In 1953, the EBR-1 was creating one new atom of nuclear fuel for every atom burned, thus the reactor could sustain its own operation
* With this creation of new cores, enough energy was created to fuel additional reactors
* A few years later, the town of Arco, Idaho became the world’s first community to get its entire power supply from a nuclear reactor
* This was achieved by temporarily attaching the town’s power grid to the reactor’s turbines
Atoms for Peace
* Began in 1953 and was designed by Eisenhower specifically to promote peaceful, commercial applications of atomic energy after the Manhattan Project and atomic bombings on Japan
* Public support for nuclear energy grew, federal nuclear energy programs shifted their focus to advancing reactor technologies
* With this came the support of utility companies, which saw nuclear energy as a cheap and environmentally safe alternative energy choice
Shippingport Atomic Power Station
* Department of Energy and the Duquesne Light Company broke ground in Shippingport, Pennsylvania in 1954 for the first commercial electric-generating station in the U.S. to use nuclear energy
* Opened on May 26, 1958, as part of Eisenhower’s “Atoms for Peace” program
* Three years later, it began supplying electricity for the Pittsburgh area
* It was by far the world’s largest commercial nuclear power plant, surpassing those already in place in the Soviet Union and Great Britain
