ORNL through the decades

A look at key developments at Oak Ridge National Laboratory from the 1940s to 2000.

THE FORTIES

In 1942, Oak Ridge was selected as the site for the World War II Manhattan Project.

1942 - Oak Ridge selected as site for World War II Manhattan Project.

1943 - Graphite Reactor and other pilot operations built in eight months at a cost of $12 million

1945 - First neutron-scattering studies at a nuclear reactor by Ernie Wollan and Cliff Shull, who won a Nobel Prize almost 50 years later for the pioneering work.

1946 - ORNL makes first radioisotope shipment (carbon-14) to a cancer hospital in St. Louis.
* Pressurized water reactor conceived and later applied to submarines.

1947 - Biologists begin using mice to study genetic effects of radiation.

1948 - Union Carbide becomes the government's contractor in Oak Ridge.

1949 - Lab scientists begin work on the PUREX process, which later became the worldwide method of recovering uranium and plutonium from spent nuclear fuels.


THE FIFTIES

In 1959, Sen. John F. Kennedy and his wife, Jacqueline, visit laboratory.

1950 - Oak Ridge School of Reactor Technology (ORSORT) established, and two new test reactors begin operation.

1952 - Based on studies of irradiated mouse embryos, Oak Ridge scientists recommend against pelvic X-rays of childbearing women during periods when pregnancy is possible.

1953 - Engineers design transportable reactor for the Army to use in remote sites such as Antarctica and the Panama Canal Zone.
* ORACLE, world's most powerful computer, starts up.

1955 - Alvin Weinberg named laboratory director, a position he would hold for 18 years.

1957 - ORNL launches first fusion experiment.

1958 - Oak Ridge Research Reactor starts up, expanding the laboratory's nuclear research base.

THE SIXTIES

In 1966 , the Graphite Reactor was named a National Historic Landmark.

1960 - Scientists develop personal radiation monitors, including the "pocket screamer" that chirps and flashes when gamma radiation levels go too high.

1961 - Work begins on radioisotope heat sources to power satellites in space.

1962 - Lab becomes a center for civil defense research to help protect U.S. population in the event of a nuclear war.

1964 - Concept of nuclear desalination is featured at UN conference.

1965 - High Flux Isotope Reactor and Molten Salt Reactor begin operations.
* Researchers begin effort to measure genetic effects of pesticides, tobacco and other chemicals.

1966 - Graphite Reactor, the world's first continuously operated nuclear reactor, named a National Historic Landmark.

1975 - Because of disruptions in the supply of Mideastern oil to the U.S., the government orders research on producing liquid and gaseous fuels from coal.

1978 - President Jimmy Carter visit ORNL.

1979 - Using neutral-beam injections, Oak Ridge engineers achieve record temperature for fusion plasma.
* Researchers help determine cause of the accident at Three Mile Island nuclear plant and assess core damage.


THE EIGHTIES

In 1982, Union Carbide announces plans to leave Oak Ridge after more than 30 years as government's chief contractor. In 1983, Martin Marietta succeeds Union Carbide as laboratory manager.
