Nuclear technology is technology that involves the nuclear reactions of atomic nuclei. Among the notable nuclear technologies are nuclear reactors, nuclear medicine and nuclear weapons. It is also used, among other things, in smoke detectors and gun sights. (Full article...)
A nuclear weapon (also known as an atom bomb, atomic bomb, nuclear bomb or nuclear warhead, and colloquially as an A-bomb or nuke) is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb). Both bomb types release large quantities of energy from relatively small amounts of matter.

The first test of a fission ("atomic") bomb released an amount of energy approximately equal to 20,000 tons of TNT (84 TJ). The first thermonuclear ("hydrogen") bomb test released energy approximately equal to 10 million tons of TNT (42 PJ). Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ). (Full article...) (Full article...)

Alabama Ordnance Works (1).jpg
The P-9 Project was the codename given during World War II to the Manhattan Project's heavy water production program. The Cominco operation at Trail, British Columbia, was upgraded to produce heavy water. DuPont built three plants in the United States: at the Morgantown Ordnance Works, near Morgantown, West Virginia; at the Wabash River Ordnance Works, near Dana and Newport, Indiana; and at the Alabama Ordnance Works, near Childersburg and Sylacauga, Alabama. The American plants operated from 1943 until 1945. The Canadian plant at Trail continued in operation until 1956. Three nuclear reactors were built using the heavy water produced by the P-9 Project: Chicago Pile 3 at Argonne, and ZEEP and NRX at the Chalk River Laboratories in Canada. (Full article...)

Ed Westcott Manhattan Project Photogragher in Oak Ridge Tennessee 2004.jpg
James Edward Westcott (January 20, 1922 - March 29, 2019) was an American photographer who was noted for his work with the United States government in Oak Ridge, Tennessee, during the Manhattan Project and the Cold War.

As one of the few people permitted to have a camera in the Oak Ridge area during the Manhattan Project, he created the main visual record of the construction and operation of the Oak Ridge production facilities and of civilian life in the enclosed community of Oak Ridge.

17 September 2021 - AUKUS
The Australian Defence Minister announces that the new strategic partnership will also include increased numbers of U.S. bombers and airplanes being based out of Australia. In addition, the Carnegie Endowment for International Peace notes that the deal has revealed a loophole in nuclear policy that does not bar states without nuclear weapons from obtaining nuclear technology for submarines and that this falls outside of IAEA inspections. (ABC News Australia) (Foreign Policy)
17 September 2021 - North Korea-United States relations
In escalating tensions over the past week, North Korea accuses the United States of double standards when it comes to condemning missile tests, saying that the U.S. only condemned North Korea the same day that South Korea also tested missiles. North Korean state media cited its chief as saying that the American response was a "vivid revelation of the American-style double-dealing attitude" and also says that unless "the U.S. drops its hostile policies towards North Korea, denuclearization can never be put on the table" of negotiations.
