Question: United States naval reactors included those found at the R&D facility in what New York city?
Context: John Tucker "Chick" Hayward (15 November 1908 – 23 May 1999) was a World War II naval aviator.  He helped develop one of the two atomic bombs that was dropped on Japan in the closing days of the war.  Later, he was a pioneer in the development of nuclear propulsion, nuclear weapons, guidance systems for ground- and air-launched rockets, and underwater anti-submarine weapons.  A former batboy for the New York Yankees, Hayward dropped out of high school and lied about his age to enlist in the United States Navy at age 16.  He was subsequently admitted to the United States Naval Academy at Annapolis, from which he graduated 51st in his class of 1930.  He volunteered for naval aviation. 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.

Knolls Atomic Power Laboratory (KAPL) is an American research and development facility based in Niskayuna, New York and dedicated to the support of the US Naval Nuclear Propulsion Program.  Developed after World War II in 1946 under a contract between General Electric and the United States government, in the 21st century KAPL is a government-owned, contractor-operated laboratory run by Bechtel Marine Propulsion Corporation for the US Department of Energy.  KAPL is responsible for the research, design, construction, operation, and maintenance of U.S. nuclear-powered warships.  It also manages work on nuclear ships at numerous shipyards across the country. MacGillivray Milne (August 19, 1882 – January 26, 1959) was a United States Navy Captain, and the 27th Governor of American Samoa from January 20, 1936, to June 3, 1938.
