The National Renewable Energy Laboratory (NREL), located in Golden, Colorado, specializes in renewable energy and energy efficiency research and development.
 NREL is a government-owned, contractor-operated facility, and is funded through the United States Department of Energy.
 This arrangement allows a private entity to operate the lab on behalf of the federal government.
 NREL receives funding from Congress to be applied toward research and development projects.
 NREL also performs research on photovoltaics (PV) under the National Center for Photovoltaics.
 NREL has a number of PV research capabilities including research and development, testing, and deployment.
 NREL's campus houses several facilities dedicated to PV research.
The Terrorist Screening Center (TSC) is a division of the National Security Branch of the Federal Bureau of Investigation.
 It is the duty of the TSC to identify suspected or potential terrorists. Though housed within the FBI, the TSC is a multi-agency organization, including representatives from the United States Department of Justice, the United States Department of State, the United States Department of Homeland Security, the United States Department of Defense, the United States Postal Service, and various private contractors.
 It is located in Vienna, Virginia, near Virginia State Route 123.
Grindelia fraxinipratensis, common name Ash Meadows gumweed, is a North American species of flowering plants in the daisy family.
 It is native to the southwestern United States, in Mojave Desert regions in Nye County in Nevada and Inyo County in California.
 Some of the Nevada populations (including the type locality) lie inside the Nevada Test Site of the United States Atomic Energy Commission
Great Lakes boreal wolf is an informal term used to describe hybrids between North American gray wolves, eastern wolves and possibly coyotes in the forests surrounding the Great Lakes.
 Introgression of gray wolf genes into Canadian populations of eastern wolves has occurred across eastern Manitoba, northern and eastern Ontario, and into southwestern Quebec.
 In the United States, gray wolves have also introgressed into the eastern wolf populations that once inhabited the western Great Lakes states of Minnesota, Wisconsin, and Michigan.
 Introgressions of coyotes into eastern wolf populations have also occurred in southern Ontario, Quebec, and all over the eastern Great Lakes states.
 While gray wolves in the northern states rarely mate with coyotes, it was long suspected that the eastern wolves which mixed with the gray wolves in the boreal forests may have also had coyote introgressions from past hybridizations with earlier coyote populations, resulting in transmittal of coyote genes into the modern day Great Lakes boreal wolves, which in turn further introduce these coyote and eastern wolf genes into other gray wolf populations.
The Nevada National Security Site (N2S2),(though the abbreviation NNSS is still used), previously the Nevada Test Site (NTS), is a United States Department of Energy reservation located in southeastern Nye County, Nevada, about 65 miles (105 km) northwest of the city of Las Vegas.
 Formerly known as the Nevada Proving Grounds, the site was established on 11 January 1951 for the testing of nuclear devices, covering approximately 1,360 square miles (3,500 km) of desert and mountainous terrain.
 Nuclear weapons testing at the Nevada Test Site began with a 1-kiloton-of-TNT (4.2 TJ) bomb dropped on Frenchman Flat on 27 January 1951.
 Many of the iconic images of the nuclear era come from the NTS.
 NNSS is operated by National Security Technologies, LLC, a joint venture of Northrop Grumman, AECOM, CH2M Hill, and Babcock & Wilcox.
Project FIRE (Flight Investigation Reentry Environment) was a United States National Air and Space Administration NASA effort to determine the effects of Atmospheric entry on spacecraft materials.
 Project FIRE used both ground testing in wind tunnels and flight tests to test the effects of reentry heating on spacecraft materials.
 Wind tunnel testing occurred at the 4-foot Unitary Plan Wind Tunnel, the High-Temperature Tunnel, and the Thermal Structures Tunnel at the Langley Research Center located in Hampton, Virginia.
 Recoverable reentry packages were flight tested using the Atlas Intercontinental ballistic missile.
 Project Fire flight tests originated from Launch Complex 12 at Cape Canaveral Air Force Station in Florida, United States.
The United States Department of Energy's State Energy Program (SEP) provides grants to states and directs funding to state energy offices from technology programs in Office of Energy Efficiency and Renewable Energy.
 States use grants to address their energy priorities and program funding to adopt emerging renewable energy and energy efficiency technologies.
According to the United States Census Bureau the following are the places in the United States with the lowest per capita or median household income.
 Locations with populations from the 2010 census are ranked by median household income as surveyed between 2008 and 2012.
 For comparison, locations are next listed with populations per capita income from the 2000 census.
 The most sizable community in 2000 (with a population of 13,138) was Kiryas Joel, New York which had a per capita income of just $4,355.
 In terms of geographic size, Pine Ridge Indian Reservation and the adjacent Rosebud Indian Reservation (Lakota Sioux Reservations, South Dakota) have long been among the lowest income areas in the United States.
 Three of the lowest ten per capita income locations in the U.S. are on these two reservations, which constitute the three largest populations in the bottom ten locations.
The Hubert H. Humphrey Building is a low-rise Brutalist office building located in Washington, D.C., in the United States.
 Originally known as the South Portal Building, the Hubert H. Humphrey Building was dedicated on November 1, 1977.
 It became the headquarters of the United States Department of Health, Education, and Welfare (HEW).
 After the department's education component was given to the newly created United States Department of Education in 1979, the newly named United States Department of Health and Human Services (HHS) continued to occupy the structure.
The Office of Energy Efficiency and Renewable Energy (EERE) is an office within the United States Department of Energy.
 Formed from other energy agencies after the 1973 energy crisis, EERE's mission is to help support the development of clean, renewable and efficiency energy technologies to America and support a global clean energy economy.
 The Office of EERE is led by the Assistant Secretary of Energy Efficiency and Renewable Energy, who oversees three technology sectors: renewable energy, sustainable transportation, and energy efficiency.
 Within these sectors are 11 major technology offices and programs that support research, development, and outreach efforts.

Question: Some Grindelia fraxinipratensis populations are located inside a United States Department of Energy reservation where what type of testing occurred?
Answer: Nuclear weapons testing
