Plutonium recovered from LWR spent fuel, while not weapons grade, can be used to produce nuclear weapons at all levels of sophistication, [25] though in simple designs it may produce only a fizzle yield. [26] Weapons made with reactor-grade plutonium would require special cooling to keep them in storage and ready for use. [27]
The pits of the first nuclear weapons were solid, with an urchin neutron initiator in their center. The Gadget and Fat Man used pits made of 6.2 kg of solid hot pressed plutonium-gallium alloy (at 400 °C and 200 MPa in steel dies – 750 °F and 29,000 psi) half-spheres of 9.2 cm (3.6 in) diameter, with a 2.5 cm (1 in) internal cavity for the initiator.
North American AT-6A (Charge Number NA-78) in flight AT-6 Texan Advanced Trainer - same as BC-1A with minor changes, powered by a 600hp R-1340-47 and armed with forward-firing 0.3in machine gun, nine original started as BC-1As and 85 built.
Gilbert Atomic Energy Manual — a 60-page instruction book written by Dr. Ralph E. Lapp; Learn How Dagwood Split the Atom — comic book introduction to radioactivity, written with the help of General Leslie Groves (director of the Manhattan Project) and John R. Dunning (a physicist who verified fission of the uranium atom) [11] [12]
The first large-scale nuclear reactors were built during World War II.These reactors were designed for the production of plutonium for use in nuclear weapons.The only reprocessing required, therefore, was the extraction of the plutonium (free of fission-product contamination) from the spent natural uranium fuel.
Included system-oriented layers and troubleshooting, assembly and disassembly aspects. The Advanced Interactive Electronic Technical Manual (A-IETM 1992) was an R&D Augmented Reality (AR) version of this system designed to help to guide the standards used in the mark-up of the documentation - the idea being a UI-independent data stream.
Plutonium carbide comes in several stoichiometries (PuC and Pu 2 C 3). [1] It can be used as a nuclear fuel for nuclear reactors in conjunction with uranium carbide . The mixture is also labeled as uranium-plutonium carbide (UPuC).
The M28 or M29 Davy Crockett Weapon System was a tactical nuclear recoilless smoothbore gun for firing the M388 nuclear projectile, armed with the W54 nuclear warhead, that was deployed by the United States during the Cold War.
