Milton Shaw
Milton Shaw (October 5, 1921 – November 24, 2001) was an American nuclear engineer who served as director of the Division of Reactor Development and Technology at the US Atomic Energy Commission from 1964 to 1973. He served in the US Navy during World War II before transitioning to the Naval Reactors program. Considered a protégé of Hyman Rickover, Shaw oversaw the construction of the USS ''Nautilus'' and USS ''Enterprise''. During his tenure at the AEC, he is credited with the obstruction of many reactor safety-related programs; and was instrumental in the termination of the Molten Salt Reactor Experiment. Biography Early life Milton Shaw was born in Knoxville, Tennessee, on October 5, 1921. He had two sisters, Ruth and Genevieve. His father, William Shaw, was a professor of agricultural chemistry at the University of Tennessee.

Liquid Metal Cooled Reactor
A liquid metal cooled nuclear reactor (LMR) is a type of nuclear reactor where the primary coolant is a liquid metal. Liquid metal cooled reactors were first adapted for breeder reactor power generation. They have also been used to power nuclear submarines. Due to their high thermal conductivity, metal coolants remove heat effectively, enabling high power density. This makes them attractive in situations where size and weight are at a premium, like on ships and submarines. Most water-based reactor designs are highly pressurized to raise the boiling point (thereby improving cooling capabilities), which presents safety and maintenance issues that liquid metal designs lack. Additionally, the high temperature of the liquid metal can be used to drive power conversion cycles with high thermodynamic efficiency. This makes them attractive for improving power output, cost effectiveness, and fuel efficiency in nuclear power plants. Liquid metals, being electrically highly conductive, can ...

Secretary Of The Navy
The Secretary of the Navy (SECNAV) is a statutory officer () and the head (chief executive officer) of the Department of the Navy, a military department within the United States Department of Defense. On March 25, 2025, John Phelan was confirmed as Secretary of the Navy. By law, the Secretary of the Navy must be a civilian at least five years removed from active military service. The secretary is appointed by the president and requires confirmation by the Senate. History The position of Secretary of the Navy was created in 1798. It was a member of the president's Cabinet until 1949, when the Secretary of the Navy (and the secretaries of the Army and Air Force) were by amendments to the National Security Act of 1947 made subordinate to the secretary of defense. From 2001 to 2019, proposals to rename the Department of the Navy to the Department of the Navy and Marine Corps, which would have also renamed the Secretary of the Navy to the Secretary of the Navy and Marine Co ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering carrier-based aircraft, shipborne aircraft. Typically it is the capital ship of a naval fleet, fleet (known as a carrier battle group), as it allows a naval force to power projection, project seaborne naval aviation, air power far from homeland without depending on local airfields for staging area, staging aerial warfare, aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear marine propulsion, nuclear-powered supercarriers that carry dozens of fighter aircraft, fighters, strike aircraft, military helicopters, airborne early warning and control, AEW&Cs and other types of aircraft such as unmanned combat aerial vehicle, UCAVs. While heavier fixed-wing aircraft such as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Submarine
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" (typically diesel-electric) submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a virtually unlimited range, making the only limits on voyage times factors such as the need to restock food or other consumables. Thus nuclear propulsion solves the problem of limited mission duration that all electric ( battery or fuel cell powered) submarines face. The high cost of nuclear technology means that relatively few of the world's military powers have fielded nuclear submarines. Radiation incidents have occurred wit ...

Alvin Weinberg
Alvin Martin Weinberg (; April 20, 1915 – October 18, 2006) was an American nuclear physicist who was the administrator of Oak Ridge National Laboratory (ORNL) during and after the Manhattan Project. He came to Oak Ridge, Tennessee, in 1945 and remained there until his death in 2006. He was the first to use the term " Faustian bargain" to describe nuclear energy. A graduate of the University of Chicago, which awarded him his doctorate in mathematical biophysics in 1939, Weinberg joined the Manhattan Project's Metallurgical Laboratory in September 1941. The following year he became part of Eugene Wigner's Theoretical Group, whose task was to design the nuclear reactors that would convert uranium into plutonium. Weinberg replaced Wigner as director of research at ORNL in 1948, and became director of the laboratory in 1955. Under his direction it worked on the Aircraft Nuclear Propulsion program, and pioneered many innovative reactor designs, including the pressurized water r ...
