than water. Sodium was chosen because it has excellent heat transfer properties, has a low operating pressure at typical reactor temperatures and it has a relatively low melting point. When used as a coolant for a nuclear reactor, water requires heavy piping since at the high reactor temperatures, water is kept under pressure. In the event of an accident, the sudden breach of the high temperature water system (among other things) necessitates a special containment vessel to capture the released pressure.
Experience gained from conducting basic nuclear technology development provided Atomics International with the experience and practical knowledge necessary for the design, construction and operation of the Sodium Reactor Experiment nuclear reactor. On July 12, 1957, the Sodium Reactor Experiment became the first nuclear reactor in the United States to produce electrical power for a commercial power grid by powering the nearby city of

Odd-numbered SNAPs: radioisotope thermoelectric generators ...
(SNAP) program largely coincided with Atomic International's Sodium Reactor Experiment effort. In the mid-1950s, Atomics International was chosen as the prime contractor to the U.S. Government for the development of the compact SNAP nuclear reactor. The number of specialized facilities located at the Santa Susana Field Laboratory rapidly increased. Following the successful 1965 launch of the SNAP 10A reactor, the U.S. Government canceled the program leaving a number of government–owned facilities at the site. In 1966, the Liquid Metal Information Center (later renamed the
Energy Technology Engineering Center

) was established by the U. S. Department of Energy as their center of liquid metal-related research. The ETEC reused many of the buildings formerly used in the SNAP program.
Other nuclear energy projects
Atomics International also engaged in a number of commercial projects. Atomics International built and operated the Atomics International Hot Lab (later renamed the Rockwell International Hot Lab) at the Santa Susana Field Laboratory. This facility performed the disassembly of fuel rods to support the on-site research and development of the SNAP reactors and for the decladding of nuclear fuel rods from off-site commercial nuclear reactors. Atomics International also developed a

As time passed, nuclear research and development activities steadily declined. As a result of this decline, Atomics International was organizationally combined with other Rockwell International operations to become the Energy Systems Group in 1978. Atomics International ceased as an autonomous business division, however, their remaining business activities were performed as the Atomics International division of Energy Systems Group, Rockwell International.

U.S. Department of Energy has accepted responsibility for the cleanup of both chemical and radiological impacts within Area IV under the 2010 Administrative Order on Consent (AOC). The AOC requires the DOE to clean up both chemical and radiological contaminants to background concentrations within the underlying soils of the 290-acre Area IV. In May 2009, the US Environmental Protection Agency began a $41.5 million survey to determine the nature and extent of any radiological contamination within Area IV.
Development and testing of nuclear reactors
: Between 1954 and 1980 at the Santa Susana Field Laboratory several nuclear reactors were built, tested and operated in Area IV. These included both nuclear reactors and critical test assemblies. A critical test assembly is a very low-power reactor that does not require an active cooling system and frequently requires a separate neutron source to maintain critical neutron flux.
:* Advanced Epithermal Thorium Reactor
![Nuclear Reactor Japan Stamp in 1957](https://upload.wikimedia.org/wikipedia/commons/d/db/Nuclear_Reactor_Japan_Stamp_in_1957.JPG)
The Advanced Epithermal Thorium Reactor was built for the Southwest Atomic Power Association at Building 100 in 1960. The AETR was used to test twenty different reactor core configurations by using an apparatus which supported a range of geometries. The AETR program was terminated in 1972.
:* Homogeneous Water Boiler-type Reactors
Atomics International designed and built a range of low-power (5 to 50,000 watts thermal) nuclear reactors for research, training and isotope production purposes. This

type of low-power nuclear reactor used a 93% enriched uranyl sulphate solution held in a critical configuration in a spherical vessel. Reactivity was controlled using an arrangement of control rods within tubes penetrating the reactor vessel. The solution did not boil; rather, neutron and gamma flux caused radiolytic decomposition of water into hydrogen and oxygen in the form of tiny bubbles that gave the impression of boiling.
One reactor model, the L-54, was purchased and installed by a number of United States universities and foreign research institutions, including Japan. The Japanese Atomic Research Institute renamed theirs Japan Research Reactor-1 (JRR-1) and the government of Japan issued a commemorative postage stamp noting the establishment of Japan's first nuclear reactor in 1957. The reactor was decommissioned in 1970 and is now maintained as

program undertaken in 1955 by the United States was the development of compact, lightweight, reliable atomic electric devices for space, land and sea. The
Atomic Energy CommissionAEC (predecessor to the
Department of EnergyDOE), was the procurement agency for the
Department of Defense (DOD) and
National Aeronautics and Space AdministrationNASA requirements. The AEC was responsible for developing technologies that would allow the requirement to be fulfilled and for carrying out the initial phases of operational tests. From the period 1955 to 1973 when the program was terminated, approximately $850 million ''then-years'' dollars were spent by the United States to develop the SNAP nuclear reactors.
Atomics International was the prime contractor to the AEC for the development of the SNAP reactors. In the late 1950s to the early 1960s, Atomics International established a number of government-owned facilities to support the SNAP program at the Energy Technology Engineering Center (ETEC) in Area IV of the

![SSFL SNAP Building Complex 6Jan64](https://upload.wikimedia.org/wikipedia/commons/3/37/SSFL_SNAP_Building_Complex_6Jan64.jpg)
:* Nuclear support operations
At the Santa Susana Field Laboratory, approximately twenty facilities were designed and built in Area IV to manage radioactive materials in support of the nuclear reactor programs. These operations included fuel fabrication, storage and reprocessing, radioactive measurement and calibration and radioactive waste management and disposal preparation. As of January 2010, only the Radioactive Materials Handling Facility remains in operation in support of the DOE's cleanup effort.
ETEC – Energy Technology Engineering Center

(ETEC) specialized in the non-nuclear testing of components which were primarily designed to transfer heat from a nuclear reactor using liquid metals instead of water or gas. Atomics International operated the ETEC as a separate division at SSFL under contract to the
U.S. Department of Energy. The ETEC operated from 1966 to 1998.
Ownership and licensing
Atomics International was a division of a private company which engaged in the commercial enterprise of selling products and services to other companies, Universities and foreign governments. Atomics International also conducted research and development for the United States Government. Operating both as a contractor to the U.S. Government and as a commercial company, Atomics International maintained authorizations allowing for the use of radioactive materials in either situation. Activities using radioactive materials owned by the Department of Energy were supervised by that government agency and no licensing was required. For facilities such as the DeSoto, Vanowen operated under a permit to operate granted and monitored by the Nuclear Regulatory Commission or the California State Department of Health Services, Radiological Health Branch. Four buildings at SSFL were licensed by the NRC: Rockwell International Hot Lab (4020), The L-85 reactor building (4093), Nuclear Materials Development Facility (4055), and the Fast Critical Experiment Laboratory (4100).
Personnel radiation exposure limitations were generally lower for those working in facilities licensed by the NRC as opposed to sites overseen by the DOE and operating personnel frequently rotated between the facilities.
