TRIGA (Training, Research, Isotopes, General Atomics) is a class of nuclear research reactor designed and manufactured by General Atomics.
General Atomics's initial projects were the TRIGA nuclear research reactor which was designed so that it was guaranteed to be safe by the laws of nature, and Project Orion.

The design team for TRIGA, which included Edward Teller, was led by the physicist Freeman Dyson.
In 1958 Dyson was a member of the design team under Edward Teller for TRIGA, a small, inherently safe nuclear reactor used throughout the world in hospitals and universities for the production of medical isotopes.

The TRIGA (Training, Research, Isotopes, General Atomic) has been built and used in hundreds of hospitals and universities worldwide for medical isotope production and research.

Pool-type reactor

TRIGA is a pool-type reactor that can be installed without a containment building, and is designed for research and testing use by scientific institutions and universities for purposes such as undergraduate and graduate education, private commercial research, non-destructive testing and isotope production.
General Atomics of La Jolla, CA manufactures TRIGA reactor fuel elements in France for the majority of these types of reactors around the world.

Uranium zirconium hydride

The TRIGA reactor uses uranium zirconium hydride (UZrH) fuel, which has a large, prompt negative fuel temperature coefficient of reactivity, meaning that as the temperature of the core increases, the reactivity rapidly decreases.
This compound, quite different from uranium hydride, is used as the fuel in the TRIGA reactor.

The Bangladesh Atomic Energy Commission operates a TRIGA research reactor at its atomic-energy facility in Savar.

Areva

TRIGA International, a joint venture between General Atomics and CERCA — then a subsidiary of AREVA of France — was established in 1996.
CERCA, a subsidiary of Areva that produces fuel for research reactors, was also involved in TRIGA, a research reactor established in 1996 with the US firm General Atomics that is used for training, research, and the production of radioisotopes.

TRIGA was originally designed to be fueled with highly enriched uranium, but in 1978 the US Department of Energy launched its Reduced Enrichment for Research Test Reactors program, which promoted reactor conversion to low-enriched uranium fuel.
