Simi Valley (Chumash: Shimiyi) is a synclinal valley in Southern California in the United States. It is an enclosed or hidden valley surrounded by mountains and hills. It is connected to the San Fernando Valley to the east by the Santa Susana Pass and the 118 (Ronald Reagan) freeway, and in the west the narrows of the Arroyo Simi and the Reagan Freeway connection to Moorpark. The relatively flat bottom of the valley contains soils formed from shales, sandstones, and conglomerates eroded from the surrounding hills of the Santa Susana Mountains to the north, which separate Simi Valley from the Santa Clara River Valley, and the Simi Hills.

Grandma Prisbrey's Bottle Village, also known as Bottle Village, is an art environment, located in Simi Valley, California. It was created by Tressa "Grandma" Prisbrey (1896–1988) from the 1950s to the 1970s. Prisbey built a "village" of shrines, walkways, sculptures, and buildings from recycled items and discards from the local landfill. Bottle Village has been designated as a historical landmark by the City of Simi Valley, County of Ventura, and State of California (California Historical Landmark No. 939. It was also listed on the National Register of Historic Places in 1996. Bottle Village closed in 1984 and was severely damaged during the 1994 Northridge earthquake.

Santa Susana High School is one of four public high schools located in the Simi Valley Unified School District in Simi Valley, California. Built in 1970, the school campus was originally designed as a junior high campus formerly known as Sequoia Junior High School. In June 1995, the Simi Valley School Board voted one junior high campus be converted into a magnet high school to accommodate the move of 9th graders into regular high school campuses, and all remaining junior high campuses be converted into middle schools. The school board elected Sequoia Junior High over Hillside Junior High because of its location. Santa Susana High School officially opened on September 5, 1996.Currently, Santa Susana High School is configured with three major classroom blocks, surrounding a quad. A large open-air amphitheater divides the classroom complex, and the school's MUR, music, stagecraft, film and broadcasting workshops, and Black Box Theater. The technical, 422-seat Performing Arts Center, dance studios, and the student parking lot are located west of the multipurpose room. The school colors are silver, black, white, and teal. The mascot is the Troubadour.

Simi Institute for Careers and Education, formerly known as Simi Valley Adult School, is the adult education division of the Simi Valley Unified School District located in eastern Ventura County, between Los Angeles and Santa Barbara Counties. School enrolments are reported to be more than 11,000 students a year with about half pursuing occupational training programs. Simi Institute is accredited by the Western Association of Schools and Colleges.

The Sodium Reactor Experiment was a pioneering nuclear power plant built by Atomics International at the Santa Susana Field Laboratory near Simi Valley, California. The reactor operated from 1957 to 1964. On July 12, 1957 the Sodium Reactor Experiment became the first nuclear reactor in California to produce electrical power for a commercial power grid by powering the nearby city of Moorpark. In July 1959, the reactor experienced a partial meltdown when 13 of the reactor's 43 fuel elements partially melted, and a controlled release of radioactive gas into the atmosphere occurred. The reactor was repaired and restarted in September 1960. In February 1964, the Sodium Reactor Experiment was in operation for the last time. Removal of the deactivated reactor was completed in 1981. Technical analyses of the 1959 incident have produced contrasting conclusions regarding the types and quantities of radioactive materials released. Members of the neighboring communities have expressed concerns about the possible impacts on their health and environment from the incident. In August 2009, 50 years after the occurrence, the Department of Energy hosted a community workshop to discuss the 1959 incident.

Apollo High School is a High School located in Simi Valley, California, United States. Its goals are to provide "a safe, caring, and academically challenging environment in which students can grow academically and personally".

The Energy Technology Engineering Center (ETEC), was a government-owned, contractor-operated complex of industrial facilities located within the 2,850-acre (11.5 km2) Santa Susana Field Laboratory (SSFL), Ventura County, California. The ETEC specialized in non-nuclear testing of components which were designed to transfer heat from a nuclear reactor using liquid metals instead of water or gas. The center operated from 1966 to 1998. The ETEC site has been closed and is now undergoing building removal and environmental remediation by the U.S. Department of Energy.

Simi Valley ( ; Chumash: Shimiyi) is a city in the valley of the same name in the southeast region of Ventura County, California, United States. Simi Valley is 40 miles (65 km) from Downtown Los Angeles, making it part of the Greater Los Angeles Area. The city sits next to Thousand Oaks, Moorpark, and Chatsworth. As of the 2020 U.S. Census the population was 126,356, up from 124,243 in 2010. The city of Simi Valley is surrounded by the Santa Susana Mountains and the Simi Hills, west of the San Fernando Valley, and northeast of the Conejo Valley. It grew as a commuter bedroom community for the cities in the Los Angeles area, and the San Fernando Valley when a freeway was built over the Santa Susana Pass. The Ronald Reagan Presidential Library, where the former president was buried in 2004, is in Simi Valley. The Reagan Library has hosted Republican primary debates in 2011, 2015, and in 2023.

Atomics International was a division of the North American Aviation company (later acquired by the Rockwell International company) which engaged principally in the early development of nuclear technology and nuclear reactors for both commercial and government applications. Atomics International was responsible for a number of accomplishments relating to nuclear energy: design, construction and operation of the first nuclear reactor in California (1952), the first nuclear reactor to produce power for a commercial power grid in the United States (1957) and the first nuclear reactor launched into outer space by the United States (1965).Atomics International undertook the development of nuclear reactors soon after being established: a series of commercial nuclear power reactors beginning with the Sodium Reactor Experiment (SRE) and a range of compact nuclear reactors culminating with the Systems for Auxiliary Nuclear Power SNAP-10A system. Both efforts were successful, despite nuclear accidents at the Santa Susana Field Laboratory, but overall interest in nuclear power steadily declined. The division transitioned to non-nuclear energy-related projects such as coal gasification and gradually ceased designing and testing nuclear reactors. Atomics International was eventually merged with another division (Rocketdyne division) of the same parent company (Rockwell International). As of 2010, all of the Atomics International facilities, except for the few remaining facilities located in the Area IV test area at the Santa Susana Field Laboratory (SSFL), have been demolished, cleaned and reused, or awaiting final cleanup.
