An Operational Reactor Safeguards Examination (ORSE) is an examination conducted by United States Navy personnel onboard U.S. Navy nuclear-powered ships. The purpose of an ORSE is to ensure that the Engineering (submarines) or Reactor (aircraft carriers) department of a nuclear-powered vessel is operating their reactor(s) in a safe manner.
The first proposal to test nuclear weapons against naval warships was made on August 16, 1945, by Lewis Strauss, future chairman of the Atomic Energy Commission.In an internal memo to Secretary of the Navy James Forrestal, Strauss argued, "If such a test is not made, there will be loose talk to the effect that the fleet is obsolete in the face of this new weapon and this will militate against ...
Nuclear test detection experiments are designed to improve the capabilities to detect, locate, and identify nuclear detonations, in particular, to monitor compliance with test-ban treaties. In the United States these tests are associated with Operation Vela Uniform before the Comprehensive Test Ban Treaty stopped all nuclear testing among ...
The Lockheed CL-1201 was a design study by Lockheed for a large 6,000 ton nuclear-powered transport aircraft in the late 1960s. One envisioned use of the concept was as an airborne aircraft carrier.
The effects of an underground nuclear test may vary according to factors including the depth and yield of the explosion, as well as the nature of the surrounding rock. [25] If the test is conducted at sufficient depth, the test is said to be contained, with no venting of gases or other contaminants to the environment. [25]
The first American nuclear-powered aircraft carrier was USS Enterprise, commissioned in 1961. All of US Navy's current carriers, which are a mix of Nimitz- and Ford-class carriers, are nuclear ...
The operation consisted of 29 explosions, of which only two did not produce any nuclear yield.Twenty-one laboratories and government agencies were involved. While most Operation Plumbbob tests contributed to the development of warheads for intercontinental and intermediate range missiles, they also tested air defense and anti-submarine warheads with smaller yields.
Satellite images and public documents helped identify likely carrier project. There have long been rumors that China is planning to build a nuclear-powered aircraft carrier, but the research by the Middlebury team is the first to confirm that China is working on a nuclear-powered propulsion system for a carrier-sized surface warship.
