Question: What mostly decommissioned nuclear production complex operated by the United States is overlooked by Rattlesnake Mountain?

Context paragraphs:
Hanford Site: The Hanford Site is a mostly decommissioned nuclear production complex operated by the United States federal government on the Columbia River in the U.S. state of Washington.  The site has been known by many names, including: Hanford Project, Hanford Works, Hanford Engineer Works and Hanford Nuclear Reservation.  Established in 1943 as part of the Manhattan Project in Hanford, south-central Washington, the site was home to the B Reactor, the first full-scale plutonium production reactor in the world.  Plutonium manufactured at the site was used in the first nuclear bomb, tested at the Trinity site, and in Fat Man, the bomb detonated over Nagasaki, Japan.

Rattlesnake Ridge: Rattlesnake Ridge (sometimes called Rattlesnake Ledge or Rattlesnake Mountain) is a mountain ridge located south of North Bend, Washington, United States.  The western end is near the intersection of State Route 18 and I-90 in Snoqualmie, Washington and runs southeast about 7 mi or 11 mi by trail.  It is the highest and easternmost of the Issaquah Alps (although Cedar Butte in the gap between Rattlesnake Ledge and the Cascade front at Mount Washington is considered by Harvey Manning to be a quasi-Alp).  A complicated maze of abandoned logging roads and constructed trails have been strung together to provide a 10.5 mi foot path from the Snoqualmie Point Trailhead at Exit 27 on I-90 all the way to the Rattlesnake Lake trailhead near Exit 32.

Rattlesnake Mountain: Rattlesnake Mountain is the name of 55 summits in the United States alone, including:

WVIT: WVIT, UHF digital channel 35 (virtual channel 30), branded on-air as NBC CT, is an NBC owned-and-operated television station licensed to New Britain, Connecticut, United States and serving the Hartford–New Haven television market.  Owned by the NBC Owned Television Stations subsidiary of the NBCUniversal division of Comcast, WVIT's offices and main studios are located on New Britain Avenue in West Hartford, and its transmitter is located on Rattlesnake Mountain in Farmington.  On cable, the station is carried primarily on channel 4 throughout the Hartford–New Haven television market.

Rattlesnake Mountain (New Jersey): Rattlesnake Mountain is a peak of the Kittatinny Mountains in Sussex County, New Jersey, United States.  The mountain stands 1489 ft high.  It lies along the Appalachian Trail in the Delaware Water Gap National Recreation Area.

Rattlesnake Mountain, Benton County, Washington: Rattlesnake Mountain (Native American name Lalíik meaning "land above the water") is a 3,527 ft (1,060 m) windswept treeless sub-alpine ridge overlooking the Hanford nuclear site.  Parts of the western slope are privately owned ranchland, while the eastern slope is under the federal protection of the Arid Lands Ecology Reserve, a unit of the Hanford Reach National Monument, managed by the United States Fish and Wildlife Service.

WRCH (FM): WRCH is a radio station in the Hartford, Connecticut, United States area and broadcasts at 100.5 FM with an Adult Contemporary format.  Its transmitter is located on Rattlesnake Mountain on the WTIC-TV tower, and a backup transmitter in "Radio Park" behind the Connecticut School of Broadcasting (its former studio location), and studios and offices located at 10 Executive Drive, all in Farmington.  Its "Pillow Talk" program on weekday evenings features a Soft Adult Contemporary format.

Redstone, New Hampshire: Redstone is an unincorporated community within the town of Conway in Carroll County, New Hampshire, United States.  It is located on the road from Center Conway to North Conway at the base of Rattlesnake Mountain.  From the late 19th century until circa 1950, Redstone was famous for its quarry of "red" granite which was mined extensively.

United States naval reactors: United States naval reactors are nuclear reactors used by the United States Navy aboard certain ships to generate the steam used to produce power for propulsion, electric power, catapulting airplanes in aircraft carriers, and a few more minor uses.  Such Naval nuclear reactors have a complete power plant associated with them.  All U.S. Navy submarines and supercarriers built since 1975 are nuclear-powered by such reactors.  There are no commissioned conventional (non-nuclear) submarines or aircraft carriers left in the U.S. Navy, since the last conventional carrier, USS "Kitty Hawk" , was decommissioned in May 2009.  The U.S. Navy had nine nuclear-powered cruisers with such reactors also, but they have since been decommissioned.  Reactors are designed by a variety of contractors, then developed and tested at one of several government (Department of Energy)-owned and prime contractor -operated facilities.  These facilities include Bettis Atomic Power Laboratory in West Mifflin, PA and its associated Naval Reactors Facility in Idaho, and Knolls Atomic Power Laboratory in Niskayuna, NY and its associated Kesselring site in West Milton, NY, all under the management of the office of Naval Reactors.  Sometimes there were full-scale nuclear-powered prototype plants built at the Naval Reactors Facility, Kesselring, and Windsor (in CT) to test the nuclear plants, which were operated for years to train nuclear-qualified sailors.

Ship-Submarine Recycling Program: The Ship/Submarine Recycling Program (SRP) is the process that the United States Navy uses to dispose of decommissioned nuclear vessels.  SRP takes place only at the Puget Sound Naval Shipyard (PSNS) in Bremerton, Washington, but the preparations can begin elsewhere.
