Very abstract and beautiful representation of the TRIGA pool-type reactor. An acronym of Training, Research, Isotopes, General Atomics, TRIGA was the innovative nuclear reactor created in 1958 by General Dynamics, under a team headed by famed physicists Edward Teller and Freeman Dyson. TRIGA variants are currently being used in over 20 countries! See more of the General Dynamics posters in our Modernism section.
