TRIGA is a class of small nuclear reactor designed and manufactured by General Atomics of the USA. TRIGA is an acronym of "Training, Research, Isotopes, General Atomics". Nuclear power station at Leibstadt, Switzerland. ...
General Atomics is a nuclear physics and defense contractor in southern California. ...
This type of reactor can be installed without a containment building, and is designed for use by scientific institutions and universities for purposes such as graduate education, private commercial research, non-destructive testing and isotope production. Isotopes are forms of a chemical element whose nuclei have the same atomic number, Z, but different atomic masses, A. The word isotope, meaning at the same place, comes from the fact that all isotopes of an element are located at the same place on the periodic table. ...
The TRIGA reactor uses uranium-zirconium-hydride (UZrH) fuel and has a design which incorporates a prompt negative temperature coefficient, meaning that as the temperature of the core increases, the efficiency of the reactor decreases - so it is physically impossible for a meltdown to occur.
The prototype for the TRIGA nuclear reactor (TRIGA Mark I) was commissioned on 3 May 1958 in San Diego and operated until shut down in 1997. It has been designated as a nuclear historic landmark by the American Nuclear Society. May 3 is the 123rd day of the year in the Gregorian calendar (124th in leap years). ...
1958 was a common year starting on Wednesday of the Gregorian calendar. ...

1997 is a common year starting on Wednesday of the Gregorian calendar. ...
The American Nuclear Society is a non-profit, educational organization established by a group of individuals who recognized the need to bring together professional activities within the fields of nuclear science and technology. ...
Mark II, Mark III and other variants of the TRIGA design have subsequently been produced.
A total of 35 TRIGA reactors have been installed at locations across the USA.
A further 35 reactors have been installed in other countries. Many of these installations were prompted by US President Eisenhower's 1953 policy of "Atoms for Peace" which sought to extend access to nuclear physics to countries in the American sphere of influence. Consequently, TRIGA reactors can be found in such diverse locations as Austria, Italy, Japan, Congo, Brazil, Vietnam, Iran, and Mexico.

I feel impelled to speak today in a language that in a sense is new--one which I, who have spent so much of my life in the military profession, would have preferred never to use. ...
New TRIGA installations by General Atomics are underway in Morocco, Thailand and Romania.
Some of the main competitors to General Atomics in the supply of research reactors are Framatome of France and Siemens AG of Germany. Siemens AG (NYSE: SI) is the worlds largest electronics company. ...
